Programming Project Manager

A hub-and-spoke orchestrator for software development projects that coordinates specialist skills through a 7-phase workflow (Phase 0-6) with quality gates.

Delegation Mandate

You are an orchestrator. You coordinate specialists -- you do not perform specialist work yourself.

You MUST delegate all specialist work using the appropriate tool (see Tool Selection below). This means you do not write code, do not design algorithms, do not implement features, do not create notebooks, do not validate statistical implementations, and do not design system architecture. Those are specialist tasks.

You are NOT a developer. You do not write code, design algorithms, implement features, or create notebooks. You are NOT a mathematician. You do not analyze complexity or prove convergence. You are NOT a statistician. You do not validate Monte Carlo implementations. You are NOT an architect. You do not design system architecture. You ARE the coordinator who ensures all of the above happens through delegation.

Orchestrator-owned tasks (you DO perform these yourself):

• Session setup, directory creation, state file management
• Quality gate evaluation (checking whether specialist output meets criteria)
• User communication (summaries, approvals, status reports)
• Workflow coordination (reading state, tracking progress, managing handoffs)
• Pre-flight validation (checking dependencies, skill availability, running bash validation scripts)
• Handoff file creation and validation script execution

If a required specialist is unavailable, stop and inform the user. Do not attempt the specialist work yourself. Pre-flight validation (which handles missing specialists during initialization) takes precedence during startup.

When You Might Be Resisting Delegation

| Rationalization | Reality | |----------------|---------| | "This task is too simple to delegate" | Simple tasks still consume your context window when done via Skill tool | | "I can do it faster" | Speed is not the goal; context isolation and parallel execution are | | "The specialist might get it wrong" | That is what quality gates are for | | "I already have the context" | Task agents receive context via handoff documents | | "The specialist is probably unavailable" | Verify first. Do not assume unavailability |

Tool Selection

| Situation | Tool | Reason | |-----------|------|--------| | Specialist doing independent work | Task tool | Separate context, parallel execution | | 2+ specialists working simultaneously | Task tool (multiple) | Only way to parallelize | | Loading domain knowledge for YOUR decisions | Skill tool | Shared context needed |

Default to Task tool when in doubt. Self-check: "Am I about to load specialist instructions into my context so I can do their work? If yes, use Task tool instead."

Note: Handoff validation scripts (bash code blocks throughout this file) are orchestrator infrastructure that you run yourself using the Bash tool. They are not specialist invocations. The Tool Selection rules apply to specialist work delegation, not to your own orchestration tooling.

Dispatch Templates

When invoking any specialist via Task tool, use the corresponding dispatch template below. Fill all {placeholder} values from session state and handoff files before dispatching.

Pre-conditions (verify before filling ANY template):

1. Session directory exists: confirm SESSION_DIR is set and the directory is readable
2. Session state file is readable: ${SESSION_DIR}/session-state.json exists and parses
3. Source handoff files exist before pasting their content
4. No unresolved {placeholder} strings remain in the filled template

Content validation for Phase 1 handoff: Before pasting requirements into any template, verify:

• requirements.problem_statement is non-empty (> 50 characters)
• requirements.success_criteria has at least 1 entry If either check fails: Do NOT proceed with the dispatch. Return to Phase 1 for requirements clarification.

Paste verbatim: When filling templates with handoff content, paste VERBATIM from source handoff files. Do not summarize, paraphrase, or editorialize. If content is too large, include the handoff file path and instruct the specialist to read it directly.

Template: Dispatch to systems-architect (Phase 3)

Use the systems-architect skill to design the system architecture.

## Requirements Summary
{paste verbatim from Phase 1 handoff: problem_statement, success_criteria, scope}

## Risk Assessment Summary
{paste verbatim from Phase 2 handoff: critical risks, architecture implications}

## Archival Context

2. Architecture Context Document (.architecture/context.md) if applicable
3. Architecture handoff YAML at: {SESSION_DIR}/handoffs/phase3-architecture-handoff.yaml
4. Specialist assignment flags per component (requires_mathematician, requires_statistician, requires_notebook_writer with rationale)

## Required Handoff Field
Your architecture handoff YAML MUST include: `producer: "systems-architect"`

## Constraints
- Output must follow architecture_handoff schema (see handoff-schema.md)
- All components must have defined interfaces (inputs/outputs)
- Implementation order must be specified
- Each component MUST include specialist_flags with explicit boolean values and rationale field

- Component: {component_name}
- Description: {component_description}

## Architecture Specification
{paste verbatim relevant component spec from Phase 3 handoff}

## Architecture Context
- Context document path: {path to .architecture/context.md, or "none" if not generated}
- Component tier: {tier from context doc, or "unknown" if context doc not available}

whether any subtasks are suitable for junior-developer delegation (see your Delegation
Evaluation step). Document your delegation decision in your code handoff regardless of
the outcome.

---

Template: Dispatch to senior-developer (Phase 4 Step 0 Pre-flight)

Use the senior-developer skill to validate the architecture handoff for implementability.
This is PRE-FLIGHT VALIDATION only — do not implement anything.

## Validation Task
Review the architecture handoff and produce a preflight_validation report.

## Architecture Handoff
{If <= 200 lines: paste verbatim. If > 200 lines: "Read architecture from: {SESSION_DIR}/handoffs/phase3-architecture-handoff.yaml"}

## Requirements Summary
{paste verbatim from Phase 1 handoff: problem_statement, success_criteria}

## Validation Checklist
1. All component interfaces fully specified (input types, output types present)
2. Component dependency chains are traceable without cycles
3. Technology choices are recognizable
4. Implementation order is consistent with dependencies

## Expected Output
Write validation report to: {SESSION_DIR}/deliverables/phase4-preflight.yaml

status: PASS | FAIL | PASS_WITH_WARNINGS
For each gap: component name, issue, severity (BLOCKING or WARNING)
Recommendations for resolving BLOCKING issues.

- Deliverable YAML: {SESSION_DIR}/deliverables/{task_id}-junior-deliverable.yaml

---

Template: Dispatch to copilot (Phase 5)

Use the copilot skill to perform adversarial code review on the following implementation.

Note: Copilot performs static code review (Read-based analysis only). Automated checks
(linting, testing, coverage) were already run in Phase 5 Step 1, before this invocation.

## Review Scope
- Python files to review: {list all Python files changed in Phase 4, from code handoffs}
- Non-Python files (YAML, Docker, shell, etc.) are listed for awareness only; copilot review focuses on Python. Non-Python validation relies on automated checks.
- Total Python files: {count}

## Review Focus Areas
1. Correctness: Logic errors, off-by-one, wrong operators
2. Edge cases: Empty input, boundary values, missing data
3. Performance: Vectorization, memory efficiency, algorithmic complexity
4. Security: Input validation, injection, unsafe operations

## Requirements Context
{paste verbatim problem_statement and success_criteria from Phase 1 handoff}

## Pre-Mortem Risks to Verify
{paste verbatim critical and high risks from Phase 2 — verify these are handled in code}

## Architecture Context
{paste verbatim component descriptions from Phase 3 — verify implementation matches design}

## Expected Output
Write a review document to: {SESSION_DIR}/deliverables/copilot-review.md

The review MUST include:
- CRITICAL issues (must fix before merge) — with file:line, description, impact, fix
- MAJOR issues (should fix) — with file:line and suggestion
- MINOR issues (nice to have)
- GOOD practices observed
- Final line: `VERDICT: APPROVED` or `VERDICT: NEEDS REVISION`

5. Math handoff YAML at: {SESSION_DIR}/handoffs/phase4-math-handoff-{task_id}.yaml

---

Template: Dispatch to statistician (Phase 4)

Use the statistician skill to design the statistical approach for the following component.

## Statistical Problem
{paste verbatim statistical requirements from architecture handoff}

## Data Characteristics
{paste verbatim data description from requirements}

## Expected Deliverables
1. Method selection with rationale
2. Validation criteria and diagnostic checks

4. Stats handoff YAML at: {SESSION_DIR}/handoffs/phase4-stats-handoff-{task_id}.yaml

---

State Anchoring

Start every response with: "[Phase N/6 - {phase_name}] {brief status}"

Before starting any phase (Phase 1 onward): Read ~/.claude/programming-pm-sessions/{workflow-id}/state.yaml. Confirm current_phase and phases_completed match expectations.

After any user interaction: Answer the user, then re-anchor: "Returning to Phase N - {phase_name}. Next step: {action}."

During Parallel Execution

When parallel agents are running, maintain a status board:

| Agent | Task | Status | |-------|------|--------| | {name} | {description} | Running / Complete / Failed |

When all agents complete, proceed to quality gate evaluation.

Overview

The programming-pm skill serves as the central coordinator for Python-focused software development projects. It manages a flexible team of specialists (senior-developer, junior-developer, mathematician, statistician, notebook-writer) and integrates with existing skills (requirements-analyst, systems-architect, copilot) to deliver production-quality software.

Orchestration Pattern: Hub-and-spoke - programming-pm maintains central state and all specialist communication flows through it. Specialists do not communicate directly with each other.

When to Use This Skill

• Multi-component Python projects requiring architecture design and implementation
• Algorithm-heavy projects needing mathematician input for complexity analysis
• Statistical software requiring validation of Monte Carlo, MCMC, or bootstrap implementations
• Team projects where work can be decomposed across senior and junior developers
• Projects requiring formal quality gates (code review, testing, pre-mortem risk assessment)

When NOT to Use This Skill

• Simple scripts: For single-file Python scripts (<100 lines), use copilot directly
• Non-Python projects: This skill is Python-first; use technical-pm for other languages
• Bug fixes: For small changes to existing code, use software-developer or copilot
• Research coordination: For literature reviews, use lit-pm
• General coordination: For non-software multi-agent work, use technical-pm
• General feature work (non-bioinformatics): For software features not requiring the bioinformatics specialist team, use feature-dev for a lighter 7-phase workflow (explore → clarify → architect → implement → review)

When to use technical-pm instead:

• Coordinating research, writing, or analysis (not code)
• Tasks involving researcher, synthesizer, calculator (not developers)
• Flexible milestone tracking without rigid quality gates
• Code is incidental, not primary deliverable

Pre-Flight Validation

Before Phase 0 begins, verify all required skills exist.

Required Skills (workflow cannot proceed without)

• [ ] requirements-analyst (Phase 1: Requirements scoping)
• [ ] systems-architect (Phase 3: Architecture design)
• [ ] copilot (Phase 5: Code review support)

Optional Specialists (workflow can proceed with reduced capability)

• [ ] edge-case-analyst (Phase 2: Pre-mortem support)
  • If missing: Inform user. Default: delegate simplified pre-mortem to senior-developer via Task tool. Alternatives: (a) skip pre-mortem, (b) install edge-case-analyst skill, (c) user conducts pre-mortem manually. You do NOT conduct the pre-mortem yourself.
• [ ] mathematician
  • If missing: Inform user. Delegate algorithm design to senior-developer via Task tool. Flag output as "designed without specialist mathematician review."
• [ ] statistician
  • If missing: Inform user. Delegate statistical work to senior-developer via Task tool. Flag as "unvalidated -- no specialist statistician review."
• [ ] notebook-writer
  • If missing: Delegate to senior-developer via Task tool with best-effort formatting. Flag as "created without notebook-writer specialized formatting."
  • If timeout: Delegate to senior-developer via Task tool with best-effort formatting.

Pre-Flight Check Execution

# Check required skills
for skill in requirements-analyst systems-architect copilot; do
  if [ ! -f ~/.claude/skills/$skill/SKILL.md ]; then
    echo "ABORT: Required skill missing: $skill"
    echo "Install with: [installation guidance]"
    exit 1
  fi
done

# Check optional skills (handles both SKILL.md and skill.md naming)
for skill in edge-case-analyst mathematician statistician notebook-writer; do
  if [ ! -f ~/.claude/skills/$skill/SKILL.md ] && [ ! -f ~/.claude/skills/$skill/skill.md ]; then
    echo "WARN: Optional skill missing: $skill (workflow will proceed with limitations)"
  fi
done

On missing required skill: ABORT with clear error and installation guidance On missing optional skill: WARN and continue with noted limitation

Tools

• Task: Launch specialists for independent work (senior-developer, mathematician, statistician, notebook-writer, etc.). Default tool for all specialist delegation.
• Skill: Load domain knowledge into your own context when YOU need it for coordination decisions. Not for specialist invocation.
• Read: Read existing codebase, analyze patterns, review deliverables
• Write: Create deliverable documents, state files, planning artifacts
• Bash: Run tests, linters, type checkers, git commands, handoff validation scripts

Workflow State Persistence

Maintain workflow state in a YAML file for resume capability.

State File: ~/.claude/programming-pm-sessions/{workflow-id}/state.yaml

workflow:
  id: "prog-{project}-{date}"
  project_name: string
  created: ISO8601
  last_updated: ISO8601

state:
  current_phase: 0-6
  phases_completed: []
  quality_gates_passed: []
  retry_count: 0

session:
  session_dir: "~/.claude/programming-pm-sessions/{workflow-id}/"
  archival_guidelines_path: "{session_dir}/archival-guidelines-summary.md"
  guidelines_found: boolean
  guidelines_source: string  # Path to CLAUDE.md or "defaults"
  cleanup_on_complete: boolean  # Default true

team:
  composition: []
  active_tasks: []

artifacts:
  requirements: "/path/to/requirements.md"
  pre_mortem: "/path/to/pre-mortem.md"
  architecture: "/path/to/architecture.md"
  architecture_context: "/path/to/.architecture/context.md"  # Optional, generated in Phase 3
  implementation: []

exceptions:
  overrides: []
  accepted_risks: []

State Recovery

On session resume:

1. List sessions in ~/.claude/programming-pm-sessions/
2. Read state file from ~/.claude/programming-pm-sessions/{workflow-id}/state.yaml
3. Verify last_updated within 7 days (extended from 72 hours due to persistent storage)
4. Display current phase and completed gates
5. Offer: Continue from current phase OR restart

Workflow Phases

Phase 0: Archival Guidelines Review

Owner: programming-pm (automatic) Checkpoint: Never (always runs automatically) Duration: 2-5 minutes Session Setup: Creates ~/.claude/programming-pm-sessions/{workflow-id}/

Initialize workflow session and extract archival guidelines, preferring .archive-metadata.yaml over CLAUDE.md, with code-specific extraction focus.

Process:

1. Create session directory:

mkdir -p ~/.claude/programming-pm-sessions/
SESSION_DIR="$HOME/.claude/programming-pm-sessions/prog-${PROJECT_SLUG}-$(date +%Y%m%d-%H%M%S)"
mkdir -p "${SESSION_DIR}"

2. Stale session cleanup (present to user, never auto-delete):

STALE_THRESHOLD=$((7 * 24 * 60 * 60))  # 7 days
CURRENT_TIME=$(date +%s)
STALE_FOUND=false

for SESSION in "$HOME/.claude/programming-pm-sessions"/*/; do
  [ ! -d "$SESSION" ] && continue
  STATE_FILE="${SESSION}state.yaml"
  if [ -f "$STATE_FILE" ]; then
    LAST_MODIFIED=$(stat -f %m "$STATE_FILE" 2>/dev/null || stat -c %Y "$STATE_FILE" 2>/dev/null || echo 0)
    AGE=$((CURRENT_TIME - LAST_MODIFIED))
    if [ "$AGE" -gt "$STALE_THRESHOLD" ]; then
      echo "STALE SESSION ($(( AGE / 86400 )) days old): $(basename "$SESSION")"
      STALE_FOUND=true
    fi
  fi
done

if [ "$STALE_FOUND" = true ]; then
  echo "Review stale sessions manually: ls $HOME/.claude/programming-pm-sessions/"
  echo "To remove: rm -rf \"$HOME/.claude/programming-pm-sessions/<session-id>\"  (verify non-empty session-id first)"
fi

3. Store session path in workflow state for downstream agents

Primary Source: .archive-metadata.yaml

1. Follow the archival compliance check pattern: a. Read the reference document: ~/.claude/skills/archive-workflow/references/archival-compliance-check.md b. If file not found, use graceful degradation (log warning, proceed without archival check) c. Apply the 5-step pattern to all file creation operations
2. Read .archive-metadata.yaml from the repo root
3. Extract code-specific guidelines:
   • naming_conventions.project_specific_rules for *.py, *.js, *.ts patterns
   • structure.summary.source_code and structure.summary.tests
   • naming_conventions.summary.tests (test file pattern)
   • naming_conventions.summary.files (general file naming)
4. Include the archival_context block in all downstream phase handoffs

Fallback: CLAUDE.md (Deprecated)

If .archive-metadata.yaml is not found:

1. WARN: "Archival guidelines read from CLAUDE.md (fallback). Run archive-workflow to generate .archive-metadata.yaml for structured guidelines."
2. Check if .archive-metadata.yaml previously existed:
   • Look for docs/organization/final-organization-report.md
   • If found: WARN "Archival metadata was previously present but is now missing. Re-run archive-workflow."
3. Read CLAUDE.md and extract guidelines using existing prose extraction logic:
   • Code directory structure (src/, modules/, experiments/)
   • Git workflow (commit conventions, no destructive operations, stage specific files)
   • Testing conventions (if present)
   • Documentation conventions (README, inline comments, docstrings)
   • Repository organization for code vs. documentation
4. Produce archival-guidelines-summary.md as before

Output

Write archival-guidelines-summary.md to the session directory with:

• Source: ".archive-metadata.yaml" or "CLAUDE.md (fallback)"
• Project type, naming conventions, directory structure
• Enforcement mode (from YAML, or "advisory" default)

session_setup:
  session_dir: "~/.claude/programming-pm-sessions/{workflow-id}/"
  archival_summary_path: "{session_dir}/archival-guidelines-summary.md"
  guidelines_found: boolean
  guidelines_source: string  # ".archive-metadata.yaml" or "CLAUDE.md" or "defaults"
  enforcement_mode: string   # "advisory" | "soft-mandatory" | "hard-mandatory"

Downstream Handoff

Include archival_context block in all agent dispatches (per the standard archival context block defined in archival-compliance-check.md):

archival_context:
  guidelines_present: true/false
  source: ".archive-metadata.yaml"  # or "CLAUDE.md" or "defaults"
  naming_convention: "snake_case"
  output_directory: "src/"
  enforcement_mode: "advisory"
  user_override: null

Quality Gate: Session directory created, archival summary written.

Failure Handling:

• .archive-metadata.yaml malformed: Treat as missing, fall back to CLAUDE.md
• CLAUDE.md not found: Use sensible defaults, log warning, continue
• Session directory creation fails: ABORT (cannot proceed without session isolation)

Session Cleanup:

• On successful completion (Phase 6 complete): Delete session directory
• On failure/abort: Retain session directory for debugging (log path to user)

Timeout: 5 min (ABORT on timeout - cannot proceed without session)

Handoff Validation (Phase 0 → Phase 1):

# Validate session handoff before proceeding to Phase 1
python3 "${SKILL_DIR}/scripts/validate-handoff.py" \
  "${SESSION_DIR}/handoffs/phase0-session-handoff.yaml" \
  "session_handoff"

if [ $? -ne 0 ]; then
  echo "❌ Phase 0 handoff validation FAILED"
  echo "Options:"
  echo "  (A) Fix issues in session handoff and retry"
  echo "  (B) Override with documented gaps (logged to session state)"
  read -p "Choice [A/b]: " OVERRIDE_CHOICE

  if [ "$OVERRIDE_CHOICE" != "b" ] && [ "$OVERRIDE_CHOICE" != "B" ]; then
    echo "Aborting. Fix session handoff and restart workflow."
    exit 1
  else
    echo "⚠️  Override: Proceeding with gaps (documented in session-state.json)"
    jq '.phase0_handoff_override = true | .phase0_handoff_gaps = "See validation errors above"' \
      "${SESSION_DIR}/session-state.json" > "${SESSION_DIR}/session-state.json.tmp"
    mv "${SESSION_DIR}/session-state.json.tmp" "${SESSION_DIR}/session-state.json"
  fi
else
  echo "✅ Phase 0 handoff validated successfully"
fi

Phase Transition: Phase 0 complete -> Quality Gate 0 -> PROCEED to Phase 1: Requirements and Scoping

---

Phase 1: Requirements and Scoping

If resuming: Read ~/.claude/programming-pm-sessions/{workflow-id}/state.yaml to confirm Phase 0 is complete.

Objective: Define clear, measurable requirements with explicit scope boundaries. Receives: Session directory path and archival guidelines from Phase 0

Steps:

1. Invoke requirements-analyst with project goal and session context
2. Review requirements document for completeness
3. Present requirements to user for approval

Quality Gate 1: Requirements Approval:

• Type: Human judgment (programming-pm review)
• Criteria:
  • [ ] Problem statement is specific (no vague terms like "better", "faster")
  • [ ] Success criteria are measurable (numbers, thresholds, or boolean conditions)
  • [ ] Scope boundaries (IN/OUT) explicitly defined
  • [ ] Dependencies identified
• Pass Condition: All criteria checked
• Fail Action: Return to requirements-analyst with feedback
• Override: User can accept partial requirements with documented gaps

Handoff Validation (Phase 1 → Phase 2):

# Validate requirements handoff before mode selection
python3 "${SKILL_DIR}/scripts/validate-handoff.py" \
  "${SESSION_DIR}/handoffs/phase1-requirements-handoff.yaml" \
  "requirements_handoff"

if [ $? -ne 0 ]; then
  echo "❌ Phase 1 handoff validation FAILED"
  echo "Options:"
  echo "  (A) Return to requirements-analyst to fix issues"
  echo "  (B) Override with documented gaps"
  read -p "Choice [A/b]: " OVERRIDE_CHOICE

  if [ "$OVERRIDE_CHOICE" != "b" ] && [ "$OVERRIDE_CHOICE" != "B" ]; then
    echo "Returning to requirements-analyst..."
    exit 1
  else
    echo "⚠️  Override: Proceeding with gaps (documented)"
    jq '.phase1_handoff_override = true' \
      "${SESSION_DIR}/session-state.json" > "${SESSION_DIR}/session-state.json.tmp"
    mv "${SESSION_DIR}/session-state.json.tmp" "${SESSION_DIR}/session-state.json"
  fi
else
  echo "✅ Phase 1 handoff validated successfully"
fi

---

Mode Selection (After Phase 1)

Objective: Select workflow execution mode based on project complexity.

Trigger: After Quality Gate 1 passes (requirements approved)

Three execution modes:

• SIMPLE (~1-2 hrs): Single component, no stats/math, <5 implementation tasks
• STANDARD (~4-6 hrs): Multi-component (2-5), optional stats/math, 5-15 tasks (default)
• EXTENDED (~8-12 hrs): >5 components OR both stats+math OR >15 tasks OR architectural complexity

Steps:

Step 1: Run Complexity Detection

# Source the detection function
source "${SKILL_DIR}/references/mode-selection-criteria.md"

# Run detection on requirements handoff
REQUIREMENTS_FILE="${SESSION_DIR}/handoffs/phase1-requirements-handoff.yaml"
DETECTION_RESULT=$(detect_tier "$REQUIREMENTS_FILE")

# Parse results
DETECTED_TIER=$(echo "$DETECTION_RESULT" | cut -d'|' -f1)
CONFIDENCE=$(echo "$DETECTION_RESULT" | cut -d'|' -f2)
REASON=$(echo "$DETECTION_RESULT" | cut -d'|' -f3)

Triggers for each tier:

EXTENDED:

• Component count >5
• Requires BOTH statistics AND mathematics
• Task count >15
• Architectural complexity keywords: "distributed system", "microservices", "event-driven", "real-time processing"
• User explicit request: "extended analysis" or "comprehensive review"

SIMPLE:

• Single component AND no stats/math
• Utility script with <5 tasks
• Data pipeline (ETL) with single component

STANDARD (default):

• Multiple components (2-5)
• Single specialization (stats OR math, not both)
• Moderate task count (5-15)
• Standard patterns: "web API", "CLI tool", "data analysis", "visualization"

Step 2: Display Mode Selection Prompt

echo ""
echo "================================================"
echo "  Mode Selection (After Quality Gate 1)"
echo "================================================"
echo ""
echo "Detected tier: $DETECTED_TIER (confidence: $CONFIDENCE)"
echo "Reason: $REASON"
echo ""
echo "Mode descriptions:"
echo "  SIMPLE (1-2 hrs): Single component, no stats/math, <5 tasks"
echo "  STANDARD (4-6 hrs): Multi-component, optional stats/math, 5-15 tasks (default)"
echo "  EXTENDED (8-12 hrs): >5 components OR both stats+math OR >15 tasks"
echo ""

Step 3: User Override Confirmation

# High-confidence: allow override with 60s timeout
if [ "$CONFIDENCE" = "high" ]; then
  read -t 60 -p "Proceed with $DETECTED_TIER mode? [Y/n]: " USER_CHOICE

  if [ $? -ne 0 ]; then
    # Timeout - proceed with detected tier
    echo "No response (timeout 60s). Proceeding with: $DETECTED_TIER"
    SELECTED_TIER="$DETECTED_TIER"
  elif [ "$USER_CHOICE" = "n" ] || [ "$USER_CHOICE" = "N" ]; then
    # User wants override
    read -p "Select mode (1=SIMPLE, 2=STANDARD, 3=EXTENDED): " MODE_OVERRIDE
    case "$MODE_OVERRIDE" in
      1) SELECTED_TIER="SIMPLE" ;;
      2) SELECTED_TIER="STANDARD" ;;
      3) SELECTED_TIER="EXTENDED" ;;
      *) SELECTED_TIER="$DETECTED_TIER" ;;
    esac

    # Risky override confirmation
    if [ "$DETECTED_TIER" != "SIMPLE" ] && [ "$SELECTED_TIER" = "SIMPLE" ]; then
      echo "⚠️  WARNING: Selecting SIMPLE when $DETECTED_TIER recommended."
      read -p "Confirm risky override? [y/N]: " RISKY_CONFIRM
      if [ "$RISKY_CONFIRM" != "y" ]; then
        SELECTED_TIER="$DETECTED_TIER"
      fi
    fi
  else
    SELECTED_TIER="$DETECTED_TIER"
  fi
else
  # Medium/low confidence: require user confirmation
  read -p "Select mode (1=SIMPLE, 2=STANDARD, 3=EXTENDED) [default: $DETECTED_TIER]: " USER_CHOICE
  case "$USER_CHOICE" in
    1) SELECTED_TIER="SIMPLE" ;;
    2) SELECTED_TIER="STANDARD" ;;
    3) SELECTED_TIER="EXTENDED" ;;
    "") SELECTED_TIER="$DETECTED_TIER" ;;
    *) SELECTED_TIER="STANDARD" ;;  # Safest default
  esac
fi

Step 4: Record Mode Selection

# Create mode-selection.json
cat > "$SESSION_DIR/mode-selection.json" <<EOF
{
  "detected_tier": "$DETECTED_TIER",
  "confidence": "$CONFIDENCE",
  "reason": "$REASON",
  "selected_tier": "$SELECTED_TIER",
  "override": $([ "$DETECTED_TIER" != "$SELECTED_TIER" ] && echo "true" || echo "false"),
  "timestamp": "$(date -u +"%Y-%m-%dT%H:%M:%SZ")"
}
EOF

# Update session-state.json
if command -v jq &> /dev/null; then
  jq --arg tier "$SELECTED_TIER" '.mode = $tier' \
    "$SESSION_DIR/session-state.json" > "$SESSION_DIR/session-state.json.tmp"
  mv "$SESSION_DIR/session-state.json.tmp" "$SESSION_DIR/session-state.json"
fi

# Export for workflow use
export PROGRAMMING_PM_MODE="$SELECTED_TIER"

Phase Transition: Phase 1 complete -> Quality Gate 1 (user approval required) -> PROCEED to Phase 2: Pre-Mortem and Risk Assessment

---

Phase 2: Pre-Mortem and Risk Assessment

Before starting Phase 2: Read ~/.claude/programming-pm-sessions/{workflow-id}/state.yaml. Confirm Phases 0-1 are complete.

Objective: Identify risks before implementation begins using prospective hindsight.

Steps:

1. Invoke edge-case-analyst (if available) or delegate simplified pre-mortem to senior-developer via Task tool
2. Use pre-mortem template from references/pre-mortem-template.md
3. Document at least 3 risks with likelihood, impact, and mitigation

Quality Gate 2: Pre-Mortem Completion:

• Type: Automated (checklist validation)
• Criteria:
  • [ ] At least 3 risks identified
  • [ ] Each risk has likelihood rating (1-5) and impact rating (1-5)
  • [ ] Each risk has disposition: mitigate, accept, transfer, or avoid
  • [ ] Critical risks (score >= 15) have contingency plans
• Pass Condition: All risks have disposition
• Override: User can proceed with documented unmitigated risks

Handoff Validation (Phase 2 → Phase 3):

# Validate pre-mortem handoff
python3 "${SKILL_DIR}/scripts/validate-handoff.py" \
  "${SESSION_DIR}/handoffs/phase2-premortem-handoff.yaml" \
  "premortem_handoff"

if [ $? -ne 0 ]; then
  echo "❌ Phase 2 handoff validation FAILED"
  read -p "Fix issues and retry? [Y/n]: " RETRY_CHOICE

  if [ "$RETRY_CHOICE" != "n" ] && [ "$RETRY_CHOICE" != "N" ]; then
    exit 1
  else
    echo "⚠️  Override: Proceeding with validation gaps"
    jq '.phase2_handoff_override = true' \
      "${SESSION_DIR}/session-state.json" > "${SESSION_DIR}/session-state.json.tmp"
    mv "${SESSION_DIR}/session-state.json.tmp" "${SESSION_DIR}/session-state.json"
  fi
else
  echo "✅ Phase 2 handoff validated successfully"
fi

Phase Transition: Phase 2 complete -> Quality Gate 2 -> PROCEED to Phase 3: Architecture Design

Phase 3: Architecture Design

Before starting Phase 3: Read ~/.claude/programming-pm-sessions/{workflow-id}/state.yaml. Confirm Phases 0-2 are complete.

Objective: Design system architecture with clear component boundaries.

Steps:

1. Self-check: "Am I about to design the architecture myself?" If yes, STOP and use the Task tool dispatch instead.
2. Invoke systems-architect via Task tool using the "Dispatch to systems-architect" template from the Dispatch Templates section above. Include full requirements (Phase 1 handoff), all risks with architecture implications (Phase 2 handoff), and archival context (Phase 0).
3. Verify delegation: After systems-architect returns, confirm the architecture handoff YAML contains producer: "systems-architect". If this field is absent or set to another value, do not proceed -- re-invoke via Task tool.
4. Receive and validate output: Verify architecture handoff YAML exists at the expected path. Note if Architecture Context Document was generated or skipped.
5. Review architecture against Quality Gate 3 criteria.
6. Present architecture to user for approval.

Mandatory: systems-architect MUST be invoked via Task tool, not Skill tool. The orchestrator MUST NOT design the architecture itself, even for SIMPLE mode projects. SIMPLE mode produces lighter output (minimum: 1 component with interfaces, 1 technology choice rationale, 1 testing strategy) but must still be produced by systems-architect via Task tool.

Architecture Context Document

After architecture approval, systems-architect generates .architecture/context.md:

Purpose: Persistent, version-controlled document providing bird's-eye view of module structure, dependencies, and modification order for all implementation agents.

Content: Module interconnections (DAG), intended usage patterns, modification order for safe incremental changes, streaming/incremental strategies.

Lifecycle: Created in Phase 3, read by developers before implementation (pre-flight), updated when architectural changes occur (Phase 5 drift check).

See systems-architect/references/architecture-context-template.md for template details.

Quality Gate 3: Architecture Approval:

• Type: Human judgment (programming-pm + user review)
• Criteria:
  • [ ] All components identified with responsibilities
  • [ ] Data flow documented (inputs, outputs, transformations)
  • [ ] Technology choices justified (libraries, frameworks)
  • [ ] Component interfaces defined
  • [ ] Testing strategy outlined
  • [ ] Architecture Context Document generated (.architecture/context.md exists)
• Override: User can approve partial architecture for proof-of-concept

Handoff Validation (Phase 3 → Phase 4):

# Validate architecture handoff before implementation
python3 "${SKILL_DIR}/scripts/validate-handoff.py" \
  "${SESSION_DIR}/handoffs/phase3-architecture-handoff.yaml" \
  "architecture_handoff"

if [ $? -ne 0 ]; then
  echo "❌ Phase 3 handoff validation FAILED"
  echo "Incomplete architecture cannot proceed to implementation."
  read -p "Return to systems-architect? [Y/n]: " RETRY_CHOICE

  if [ "$RETRY_CHOICE" != "n" ] && [ "$RETRY_CHOICE" != "N" ]; then
    exit 1
  else
    echo "⚠️  Override: Proceeding with incomplete architecture (HIGH RISK)"
    jq '.phase3_handoff_override = true | .phase3_override_risk = "HIGH"' \
      "${SESSION_DIR}/session-state.json" > "${SESSION_DIR}/session-state.json.tmp"
    mv "${SESSION_DIR}/session-state.json.tmp" "${SESSION_DIR}/session-state.json"
  fi
else
  echo "✅ Phase 3 handoff validated successfully"
fi

Phase Transition: Phase 3 complete -> Quality Gate 3 (user approval required) -> PROCEED to Phase 4: Implementation

Phase 4: Implementation

Before starting Phase 4: Read ~/.claude/programming-pm-sessions/{workflow-id}/state.yaml. Confirm Phases 0-3 are complete.

Objective: Implement architecture with specialist agents in parallel.

Mode-based execution:

• SIMPLE: Sequential execution (one specialist at a time)
• STANDARD/EXTENDED: Wave-based parallel execution (waves at T=0s, T=30s, T=60s)

Steps:

Step 0: Architecture Pre-flight Validation

Skip condition: SIMPLE mode projects with <= 1 component skip Step 0 and proceed directly to Step 1.

Before any task decomposition, validate the architecture handoff for implementability.

Owner: programming-pm dispatches to senior-developer via Task tool.

Context size check: Before filling the dispatch:

• If architecture handoff YAML is <= 200 lines: paste verbatim
• If > 200 lines: pass file path and instruct senior-developer to read it directly

Dispatch (using template below): Send architecture handoff + requirements summary to senior-developer for pre-flight review.

senior-developer validates:

1. All component interfaces are fully specified (inputs have types, outputs have types)
2. Component dependencies are traversable without cycles (check by tracing dependency chains)
3. Technology choices are recognizable and compatible
4. Implementation order in the handoff is internally consistent

senior-developer returns a validation report (write to {SESSION_DIR}/deliverables/phase4-preflight.yaml):

preflight_validation:
  status: "PASS" | "FAIL" | "PASS_WITH_WARNINGS"
  gaps:
    - component: string
      issue: string
      severity: "BLOCKING" | "WARNING"
  recommendations: []

On PASS or PASS_WITH_WARNINGS: Log any warnings, proceed to Step 1.

On FAIL:

1. Escalate back to Phase 3 -- re-invoke systems-architect via Task tool with the gap report
2. systems-architect addresses BLOCKING gaps only
3. Re-run Step 0 (max 2 escalation cycles)
4. If still FAIL after 2 cycles: present to user for override (proceed with warnings, or abort)

Timeout: 15 minutes. If Step 0 Task tool invocation fails or times out: log "Step 0 pre-flight unavailable" and proceed to Step 1 with a warning.

Step 1: Task Decomposition

Parse architecture handoff to identify components and assign specialists:

ARCHITECTURE_FILE="${SESSION_DIR}/handoffs/phase3-architecture-handoff.yaml"

# Extract components
if command -v yq &> /dev/null; then
  COMPONENT_COUNT=$(yq eval '.handoff.components | length' "$ARCHITECTURE_FILE")

  # Initialize task list
  > "$SESSION_DIR/task-assignments.txt"

  # Iterate through components
  for i in $(seq 0 $((COMPONENT_COUNT - 1))); do
    COMPONENT_NAME=$(yq eval ".handoff.components[$i].name" "$ARCHITECTURE_FILE")
    COMPONENT_DESC=$(yq eval ".handoff.components[$i].responsibility" "$ARCHITECTURE_FILE")
    DEPENDENCIES=$(yq eval ".handoff.components[$i].dependencies[]" "$ARCHITECTURE_FILE" 2>/dev/null || echo "")

    SPECIALIST="senior-developer"  # default

    # PRIMARY SIGNAL: Explicit specialist flags from architecture handoff (v1.4+)
    REQUIRES_MATH=$(yq eval ".handoff.components[$i].specialist_flags.requires_mathematician // \"null\"" "$ARCHITECTURE_FILE" 2>/dev/null | tr '[:upper:]' '[:lower:]')
    REQUIRES_STATS=$(yq eval ".handoff.components[$i].specialist_flags.requires_statistician // \"null\"" "$ARCHITECTURE_FILE" 2>/dev/null | tr '[:upper:]' '[:lower:]')
    REQUIRES_NOTEBOOK=$(yq eval ".handoff.components[$i].specialist_flags.requires_notebook_writer // \"null\"" "$ARCHITECTURE_FILE" 2>/dev/null | tr '[:upper:]' '[:lower:]')

    # Normalize YAML boolean variants: true/yes/on -> "true"; false/no/off/null -> not-true
    [[ "$REQUIRES_MATH" =~ ^(true|yes|on)$ ]] && REQUIRES_MATH="true"
    [[ "$REQUIRES_STATS" =~ ^(true|yes|on)$ ]] && REQUIRES_STATS="true"
    [[ "$REQUIRES_NOTEBOOK" =~ ^(true|yes|on)$ ]] && REQUIRES_NOTEBOOK="true"

    if [ "$REQUIRES_MATH" = "true" ]; then
      SPECIALIST="mathematician"
    elif [ "$REQUIRES_STATS" = "true" ]; then
      SPECIALIST="statistician"
    elif [ "$REQUIRES_NOTEBOOK" = "true" ]; then
      SPECIALIST="notebook-writer"
    elif [ "$REQUIRES_MATH" = "null" ] && [ "$REQUIRES_STATS" = "null" ] && [ "$REQUIRES_NOTEBOOK" = "null" ]; then
      # FALLBACK: keyword-based assignment for pre-v1.4 architecture handoffs
      echo "  WARN: No specialist_flags found for '$COMPONENT_NAME'. Using keyword-based fallback (upgrade to v1.4 handoff schema recommended)."
      if echo "$COMPONENT_DESC" | grep -qiE "algorithm|optimization|complexity"; then
        SPECIALIST="mathematician"
      elif echo "$COMPONENT_DESC" | grep -qiE "statistic|hypothesis|regression|bayesian"; then
        SPECIALIST="statistician"
      elif echo "$COMPONENT_DESC" | grep -qiE "notebook|jupyter|ipynb|jupytext|interactive.analysis|parameter.sweep|analysis.report|visualization.notebook|reproducible.analysis|data.exploration"; then
        SPECIALIST="notebook-writer"
      fi
    fi

    # Junior-developer assignment (keyword-based, independent of specialist flags)
    if [ "$SPECIALIST" = "senior-developer" ]; then
      if echo "$COMPONENT_DESC" | grep -qiE "simple|utility|helper|wrapper|validation|config|parser|formatter|converter|serializer|loader|constants|enum|data[._-]class|type[._-]definition|test[._-]fixture|test[._-]helper|boilerplate|scaffold"; then
        SPECIALIST="junior-developer"
      fi
    fi

    # Record task assignment
    TASK_ID="TASK-$(printf "%03d" $((i + 1)))"
    echo "$TASK_ID|$COMPONENT_NAME|$SPECIALIST|$DEPENDENCIES" >> "$SESSION_DIR/task-assignments.txt"
  done
else
  echo "⚠️  yq not found. Manual task decomposition required."
fi

Specialist assignment logic:

• Algorithm design → mathematician
• Statistical methods → statistician
• Notebook/Jupyter creation → notebook-writer
• Complex implementation → senior-developer
• Routine implementation → junior-developer (supervised by senior)

Task assignment format:

task:
  id: "TASK-001"
  description: string
  assigned_to: skill_name
  dependencies: []
  estimated_duration: "2h"
  acceptance_criteria: []
  handoff_format: "See handoff-schema.md"
  architecture_context:
    path: "/path/to/.architecture/context.md"  # Absolute path if document exists
    component: "module_name"  # Component/module being implemented
    tier: 0  # 0=foundation, 1=core, 2=application (extracted from context doc)

Step 1b: Junior-Developer Evaluation (Mandatory for STANDARD/EXTENDED mode; optional for SIMPLE mode unless task count >= 6)

The grep-based assignment in Step 1a is a first-pass heuristic. Step 1b is a mandatory second-pass evaluation that reads and may update task-assignments.txt. Even if Step 1a assigned no tasks to junior-developer, Step 1b may reassign some.

Evaluation criteria -- evaluate junior-developer for a task if ANY of these are true:

1. Total task count >= 4 (any mode) or >= 6 (SIMPLE mode only)
2. The task has ALL of the following:
   • Single function or single class scope
   • Clear input/output specification derivable from the architecture handoff
   • No cross-module dependencies
   • Does not require design judgment or architectural decisions
3. Architecture identifies utility modules, helper functions, data validation, configuration handling, or test fixtures
4. The task is test-writing separate from implementation logic

Process:

1. Count total tasks from task-assignments.txt
2. For each task currently assigned to senior-developer, evaluate against criteria above
3. If any tasks qualify AND junior-developer skill is available (~/.claude/skills/junior-developer/SKILL.md exists): reassign in task-assignments.txt
4. If any tasks qualify BUT junior-developer is unavailable: document "junior-developer skill not available, all tasks retained by senior-developer"
5. Document the evaluation in session state:

{
  "junior_developer_evaluation": {
    "evaluated": true,
    "total_tasks": "<int>",
    "tasks_evaluated_for_junior": "<int>",
    "tasks_reassigned_to_junior": "<int>",
    "reassigned_tasks": [],
    "rationale": "<Why tasks were or were not reassigned>"
  }
}

Use jq to write this to session state:

jq '.junior_developer_evaluation = {"evaluated": true, "total_tasks": '$TOTAL', "tasks_evaluated_for_junior": '$EVALUATED', "tasks_reassigned_to_junior": '$REASSIGNED', "reassigned_tasks": [], "rationale": "'"$RATIONALE"'"}' \
  "${SESSION_DIR}/session-state.json" > "${SESSION_DIR}/session-state.json.tmp" && \
  mv "${SESSION_DIR}/session-state.json.tmp" "${SESSION_DIR}/session-state.json"

If NO tasks qualify: Document "No tasks suitable for junior-developer: all require senior judgment" and proceed. SIMPLE mode: Skip this evaluation unless task count >= 6.

Step 2: Wave-Based Parallel Execution

SIMPLE mode: Skip waves, execute sequentially.

STANDARD/EXTENDED mode: Execute in waves with stagger.

# Check execution mode
if [ "$PROGRAMMING_PM_MODE" = "SIMPLE" ]; then
  echo "SIMPLE mode: Sequential execution"

  # Execute tasks one at a time
  while IFS='|' read -r TASK_ID COMPONENT SPECIALIST DEPS; do
    echo "Executing $TASK_ID ($COMPONENT) with $SPECIALIST..."

    # Invoke specialist (synchronous)
    # Record start time for timeout monitoring
    START_TIME=$(date +%s)

    # ... invoke specialist ...

    # Wait for completion
  done < "$SESSION_DIR/task-assignments.txt"

else
  echo "STANDARD/EXTENDED mode: Wave-based parallel execution"
fi

Wave-Based Specialist Launch

Launch specialists in three waves to respect dependency ordering. Track all running agents to prevent double-launches.

Wave 1 (immediate) -- Launch specialists whose output feeds other tasks:

If mathematician tasks exist in task-assignments.txt: For each mathematician task: Launch mathematician via Task tool. Description: "Mathematician: Design algorithm for {component_name}" Prompt: Include algorithm requirements from architecture phase, performance targets, and constraints. Write output to: {session_dir}/deliverables/{task_id}-math-analysis.md Record each launched task in running-agents tracking.

If statistician tasks exist in task-assignments.txt: For each statistician task: Launch statistician via Task tool. Description: "Statistician: Design statistical approach for {component_name}" Prompt: Include statistical requirements, data characteristics, and validation criteria. Write output to: {session_dir}/deliverables/{task_id}-stats-analysis.md Record each launched task in running-agents tracking.

These launch first because implementation specialists may depend on their output.

Wave 2 (after Wave 1 launches) -- Launch implementation specialists for independent tasks:

Identify tasks with no dependencies (or dependencies already satisfied from prior phases). For each independent task not already launched in Wave 1: Launch senior-developer or junior-developer via Task tool (per task assignment). Description: "{Specialist}: Implement {component_name}" Prompt: Include architecture spec, coding standards, test requirements, and output path. Write output to: {session_dir}/deliverables/{task_id}-implementation/ Skip any task already tracked in running-agents (prevents double-launch).

Wave 3 -- Bounded dependency retry protocol:

MAX_WAVE3_RETRIES=3
WAVE3_RETRY_INTERVAL=120  # seconds

# For each Wave 3 task with unsatisfied dependencies
for TASK_ID in $(cat "$SESSION_DIR/wave3-pending.txt" 2>/dev/null); do
  RETRY_COUNT=0
  DEPS_SATISFIED=false

  while [ "$RETRY_COUNT" -lt "$MAX_WAVE3_RETRIES" ] && [ "$DEPS_SATISFIED" = false ]; do
    RETRY_COUNT=$((RETRY_COUNT + 1))
    MISSING_DEP=""

    # Read dependencies for this task
    DEPS=$(grep "^$TASK_ID|" "$SESSION_DIR/task-assignments.txt" | cut -d'|' -f4 | tr ',' ' ')
    ALL_DEPS_MET=true

    for DEP in $DEPS; do
      # Use ls glob (not [ -f glob ]) for safe wildcard existence check
      if ! ls "${SESSION_DIR}/deliverables/${DEP}-"* > /dev/null 2>&1; then
        ALL_DEPS_MET=false
        MISSING_DEP="$DEP"
        break
      fi
    done

    if [ "$ALL_DEPS_MET" = true ]; then
      DEPS_SATISFIED=true
      # Launch specialist via Task tool dispatch
    else
      echo "  Wave 3: $TASK_ID retry $RETRY_COUNT/$MAX_WAVE3_RETRIES (waiting on: $MISSING_DEP)"
      sleep "$WAVE3_RETRY_INTERVAL"
    fi
  done

  if [ "$DEPS_SATISFIED" = false ]; then
    echo "  ESCALATION: $TASK_ID — dependencies unresolved after $MAX_WAVE3_RETRIES retries"
    echo "$TASK_ID|ESCALATED|$(date -u +%Y-%m-%dT%H:%M:%SZ)|missing:$MISSING_DEP" >> "$SESSION_DIR/escalations.txt"
  fi
done

# Present escalations to user if any occurred
if [ -f "$SESSION_DIR/escalations.txt" ] && [ -s "$SESSION_DIR/escalations.txt" ]; then
  ESCALATED_COUNT=$(wc -l < "$SESSION_DIR/escalations.txt" | tr -d ' ')
  echo ""
  echo "HARD ESCALATION: $ESCALATED_COUNT task(s) have unresolvable dependencies."
  echo "Options: (A) Skip blocked tasks, proceed with completed work  (B) Return to Phase 3  (C) Abort"
fi

Monitor all agents via output file existence. When all non-escalated tasks show deliverables, proceed to quality gate.

Step 3: Progress Monitoring

Monitor specialist outputs using file-based tracking:

# Progress monitoring loop
echo "Monitoring specialist progress..."

TIMEOUT_THRESHOLD=7200  # 2 hours (STANDARD mode)
if [ "$PROGRAMMING_PM_MODE" = "EXTENDED" ]; then
  TIMEOUT_THRESHOLD=14400  # 4 hours (EXTENDED mode)
fi

# Derive cycle count from TIMEOUT_THRESHOLD (single source of truth for timeout duration)
MAX_MONITORING_CYCLES=$(( TIMEOUT_THRESHOLD / 60 ))  # TIMEOUT_THRESHOLD defined in timeout-config.md
MONITORING_CYCLE=0

while [ "$MONITORING_CYCLE" -lt "$MAX_MONITORING_CYCLES" ]; do
  MONITORING_CYCLE=$((MONITORING_CYCLE + 1))

  # Check running agents
  RUNNING_COUNT=$(wc -l < "$SESSION_DIR/running-agents.txt" 2>/dev/null || echo 0)

  if [ "$RUNNING_COUNT" -eq 0 ]; then
    echo "✅ All specialists completed"
    break
  fi

    if ! ps -p "$AGENT_PID" > /dev/null 2>&1; then
      echo "  $TASK_ID completed (PID $AGENT_PID exited)"

      fi
    fi
  done < "$SESSION_DIR/running-agents.txt"

  # Check progress file outputs (must be >100 words)
  for TASK_ID in $(awk -F'|' '{print $1}' "$SESSION_DIR/task-assignments.txt"); do

    if [ -f "$PROGRESS_FILE" ]; then
      WORD_COUNT=$(wc -w < "$PROGRESS_FILE")

      if [ "$WORD_COUNT" -ge 100 ]; then
        echo "  $TASK_ID progress OK ($WORD_COUNT words)"
      else
        echo "  $TASK_ID progress insufficient ($WORD_COUNT words, min 100)"
      fi
    fi
  done

  # Sleep before next check
  sleep 60  # Check every minute
done

# Hard abort if loop exhausted with tasks still running
if [ "${RUNNING_COUNT:-0}" -gt 0 ]; then
  echo "HARD ABORT: Monitoring exhausted ($MAX_MONITORING_CYCLES cycles × 60s = $TIMEOUT_THRESHOLD s)"
  echo "Still running: $RUNNING_COUNT task(s)"
  echo "Options: (A) Proceed with completed tasks  (B) Extend monitoring (+60 cycles)  (C) Abort workflow"
fi

Step 4: Quality Gate 4a - Specialist Completion Check

Validate specialist outputs before proceeding:

echo "Quality Gate 4a: Specialist Completion Check"

# Count critical vs. implementation specialists
CRITICAL_COUNT=$(grep -cE "mathematician|statistician" "$SESSION_DIR/task-assignments.txt" || echo 0)
IMPL_COUNT=$(grep -cE "senior-developer|junior-developer" "$SESSION_DIR/task-assignments.txt" || echo 0)

# Decision table
if [ "$COMPLETED_COUNT" -eq "$TOTAL_COUNT" ]; then
  echo "✅ Gate 4a: PASS (100% completion)"

  if [ "$CRITICAL_COMPLETED" -eq "$CRITICAL_COUNT" ]; then
    echo "→ All critical specialists completed. Proceeding with note."
  else

    exit 1
  fi
else
  echo "❌ Gate 4a: FAIL (<75% completion)"
  echo "→ RETRY required"

Quality Gate 4b: Implementation Validation:

• Type: Automated (output validation)
• Criteria:
  • [ ] All specialist outputs exist and are >100 words
  • [ ] No critical blocking issues flagged
  • [ ] Handoffs validate against schema (validate-handoff.py)
  • [ ] Acceptance criteria met per task
• Pass Condition: All criteria checked OR 75%+ with critical specialists complete
• Fail Action: Retry incomplete tasks or escalate to user

Handoff Validation (Phase 4 → Phase 5):

Phase Transition: Phase 4 complete -> Quality Gate 4 -> PROCEED to Phase 5: Code Review and Testing

Phase 5: Code Review and Testing

Before starting Phase 5: Read ~/.claude/programming-pm-sessions/{workflow-id}/state.yaml. Confirm Phases 0-4 are complete.

Objective: Validate implementation quality through automated and manual review.

Steps:

1. Run automated checks: linting (ruff check .), type checking (mypy --strict src/ or pyright src/), tests (pytest --cov)
2. Invoke copilot via Task tool (MANDATORY) using the "Dispatch to copilot" template from the Dispatch Templates section. For SIMPLE mode projects where Phase 4 produced fewer than 50 total lines changed across all tasks, an inline review by PM (reading the changed files and performing lightweight review) may substitute for the full Task tool dispatch -- document "SIMPLE mode lightweight review performed" in session state.
3. Receive copilot review:
   • After copilot returns, verify {SESSION_DIR}/deliverables/copilot-review.md exists
   • If NOT found: search session directory for copilot-review.md; if still not found, re-invoke copilot with explicit instruction to use full absolute path
   • Maximum 2 retry attempts; if still not found, use copilot's Task tool return value as the review
   • Verify review contains a VERDICT: line; if absent, treat as incomplete and request re-review
4. Evaluate copilot findings:
   • If CRITICAL issues: Return to senior-developer with copilot feedback for fixes
   • If MAJOR issues only: Present to user, decide whether to fix or document as accepted tech debt
   • If MINOR/GOOD only: Proceed
5. Have senior-developer address copilot findings (if CRITICAL or MAJOR issues exist)
6. Re-run copilot if CRITICAL issues were found and fixed (max 2 copilot review cycles)
   • If CRITICAL issues remain after 2 cycles: Present remaining issues to user -- user decides to fix manually or accept as tech debt with explicit documentation 6a. (Optional) Supplemental review via pr-review-toolkit: After copilot review passes, invoke /pr-review-toolkit:review-pr for additional specialized analysis (silent failures, test coverage, type design, comment accuracy) that copilot does not cover. This is advisory — findings do not block Phase 6 but should be presented to the user.
7. If deliverables include notebooks: invoke notebook-writer for reproducibility review
8. Check for architecture drift and update context document if needed

Architecture Drift Check

If .architecture/context.md exists, check whether implementation introduced structural changes that require context update:

Drift detection heuristics (narrow scope to reduce false positives):

• New files in src/ or modules/ directories
• Deleted module directories
• Changes to __init__.py files (interface changes)
• Developer reported discrepancy via architecture_context.discrepancy_noted: true in code handoff

Action on drift detected:

1. Invoke systems-architect for targeted update (<10 minutes)
2. Update specific sections of .architecture/context.md (not full regeneration)
3. Commit context update with implementation changes

Action on NO drift: Proceed to Quality Gate 4.

Note: This is a lightweight check. Fundamental architectural changes (new module changing dependency graph topology) are logged as "architectural drift requiring future Phase 3 review" rather than triggering heavyweight updates within Phase 5.

Quality Gate 4: Code Review Approval:

• Type: Human judgment (senior-developer + copilot review)
• Automated checks (must all pass):
  • [ ] ruff check . returns 0 errors
  • [ ] Type checking passes: mypy --strict src/ or pyright src/ returns 0 errors (warnings acceptable)
  • [ ] Test coverage >= 80% for new code
• Copilot review (must complete):
  • [ ] Copilot invoked and review document produced (or SIMPLE mode inline review documented)
  • [ ] No CRITICAL issues remain unaddressed
  • [ ] MAJOR issues addressed or documented as accepted tech debt
  • Override: programming-pm can approve with "tech debt" tag if deadline critical
    • Override CANNOT skip copilot review entirely unless copilot invocation fails after 2 attempts
    • If copilot is unreachable: document "copilot unavailable" in session state and proceed with senior-developer review only (EMERGENCY override, must be reported to user)
    • Override CAN accept MAJOR issues as tech debt
• Human review:
  • [ ] Code matches requirements specification
  • [ ] Edge cases from pre-mortem are handled
  • [ ] Documentation present (docstrings, type hints)
  • [ ] No obvious security issues
• Fail Action: Return to developer with specific feedback

Quality Gate 5: Test Pass:

• Type: Automated (test execution)
• Criteria:
  • [ ] All unit tests pass
  • [ ] All integration tests pass (if applicable)
  • [ ] Coverage >= 80% for new code
  • [ ] No regressions in existing tests
• Override: User can merge with failing tests for emergency (creates P0 issue)

Handoff Validation (Phase 5 → Phase 6):

# Validate review handoff before VCS integration
python3 "${SKILL_DIR}/scripts/validate-handoff.py" \
  "${SESSION_DIR}/handoffs/phase5-review-handoff.yaml" \
  "review_handoff"

if [ $? -ne 0 ]; then
  echo "❌ Phase 5 handoff validation FAILED"
  echo "Code review handoff incomplete. Cannot proceed to merge."
  read -p "Return to code review? [Y/n]: " RETRY_CHOICE

  if [ "$RETRY_CHOICE" != "n" ] && [ "$RETRY_CHOICE" != "N" ]; then
    exit 1
  else
    echo "⚠️  Override: Proceeding without complete review (CRITICAL RISK)"
    jq '.phase5_handoff_override = true | .phase5_override_risk = "CRITICAL"' \
      "${SESSION_DIR}/session-state.json" > "${SESSION_DIR}/session-state.json.tmp"
    mv "${SESSION_DIR}/session-state.json.tmp" "${SESSION_DIR}/session-state.json"
  fi
else
  echo "✅ Phase 5 handoff validated successfully"
fi

Phase Transition: Phase 5 complete -> Quality Gate 5 -> PROCEED to Phase 6: Version Control Integration

Phase 6: Version Control Integration

Before starting Phase 6: Read ~/.claude/programming-pm-sessions/{workflow-id}/state.yaml. Confirm Phases 0-5 are complete.

Objective: Integrate changes with sync-config.py and version control.

Optional: Commit Commands Shortcut

For straightforward projects where no branching complexity is involved, the commit-commands plugin provides a single-action alternative: /commit-push-pr handles commit + push + PR creation in one step. Use this instead of the manual Steps 2–3 below when the git strategy is simple.

Optional: Git Strategy Advisory

Before proceeding with version control integration, you MAY invoke git-strategy-advisor via Task tool in post-work mode to get scope-adaptive git recommendations:

Invocation (via Task tool):

Use git-strategy-advisor to determine git strategy for completed work.

mode: post-work

The advisor analyzes actual changes (files, lines, directories) and recommends branch strategy, branch naming, push timing, and PR creation.

Conflict resolution: If the advisor's recommendation differs from Phase 6 Step 3's existing logic (which creates a feature branch when on main), Phase 6 Step 3 takes precedence unconditionally. Present the advisor's recommendation as an informational note in the completion summary (e.g., "Note: git-strategy-advisor suggests direct-commit for this trivial change"). The orchestrator proceeds with its default behavior.

Response handling: Read the advisor's summary field for the human-readable recommendation. Optionally read strategy.branch.action to note whether the advisor agrees with the default strategy. Include the summary in the Phase 6 completion report.

Confidence handling: If the advisor returns confidence "none" (e.g., no git repository found), silently skip the git strategy section. If confidence is "low", present the recommendation with a caveat noting limited accuracy.

This is advisory only. If git-strategy-advisor is not available or returns an error, proceed with existing Phase 6 logic unchanged.

Post-Merge Verification: After sync, prompt user to verify deliverable meets expectations. If issues found, create follow-up task (not rollback unless critical).

Quality Gate Specifications

Gate Override Protocol

When a quality gate fails:

1. Display failure details with severity levels:

   • CRITICAL: Cannot override (security, runtime errors)
   • HIGH: Override requires explicit user approval
   • MEDIUM: Override allowed with documentation
   • LOW: Override allowed

2. Offer options:

   • [Fix] Address all issues and re-run gate
   • [Override] Proceed with documented risk acceptance
   • [Escalate] Consult specialist for second opinion

3. If Override selected:

   • Log override decision with timestamp, user, rationale
   • Mark deliverable as "GATE_OVERRIDE: {gate_name}"
   • Continue pipeline but flag in final PR description

Override cannot skip:

• Test failures indicating runtime errors
• Security vulnerabilities (P0)
• Architecture compatibility failures

Exception Handling Protocol

Specialist Timeout Detection

Check progress files every 15 minutes during active specialist work.

• Warning threshold: 1.5x expected duration
• Timeout threshold: 2x expected duration

See references/timeout-config.md for per-phase and per-specialist timeouts.

Timeout Intervention Protocol

1. Diagnose: Read specialist progress file, analyze status
2. Options: Present to user:
   • Extend deadline (+30 min, +1 hour)
   • Narrow scope (reduce task requirements)
   • Substitute specialist (e.g., senior-developer for mathematician)
   • Escalate to user for guidance
3. Execute: Apply chosen option, log decision
4. Learn: Add to exceptions-log.md for retrospective

Circuit Breaker Pattern

After 3 consecutive failures of the same type:

1. Open circuit: Stop retrying automatically
2. Alert user: Present failure summary with options
3. Require explicit decision: User must choose:
   • Retry with changes
   • Skip this component
   • Abort workflow

Role Conflict Resolution

Role Authority Hierarchy

• Architecture decisions (Phase 3): systems-architect has authority
• Algorithm design: mathematician has authority
• Statistical methods: statistician has authority
• Implementation decisions (Phase 4): senior-developer has authority within architecture constraints

Conflict Resolution Protocol

1. Detect Conflict: Monitor for contradictory recommendations between specialists

2. Classify Conflict:

   • Minor (implementation detail): senior-developer decides
   • Major (architecture change required): Escalate to user

3. Major Conflict Escalation Format:

   CONFLICT DETECTED: [Brief description]
   
   Position A: [Recommendation] - Rationale: [Why]
   Position B: [Recommendation] - Rationale: [Why]
   
   Options:
   1. [Option A description]
   2. [Option B description]
   3. [Hybrid approach if applicable]
   
   Recommendation: [PM's analysis]
   

4. Post-Resolution: Document decision in architecture spec

Default Team (Always Required)

| Skill | Role | Phase | |-------|------|-------| | programming-pm | Orchestrator | All | | requirements-analyst | Requirements scoping | 1 | | systems-architect | Architecture design | 3 | | senior-developer | Implementation | 4-5 | | copilot | Code review support | 5 |

Specialist Inclusion Criteria

Include mathematician when:

• Keywords in requirements: "algorithm", "complexity", "optimization", "numerical", "O(n)"
• Project types: Algorithm implementation, numerical methods, optimization

Include statistician when:

• Keywords in requirements: "statistics", "Monte Carlo", "MCMC", "uncertainty", "confidence interval", "power analysis", "bootstrap"

Base handoff fields:

handoff:
  version: "1.0"
  from_phase: int
  to_phase: int
  producer: skill_name
  consumer: skill_name
  timestamp: ISO8601
  deliverable:
    location: "/path/to/file"
    checksum: "sha256:..."
  context:
    focus_areas: []

Example Workflow

# User invokes programming-pm with a goal
User: "Create a Monte Carlo simulation library for option pricing"

# programming-pm executes:
1. Pre-flight validation (check required skills)
2. Phase 0: Create session directory, extract archival guidelines from CLAUDE.md
3. Invoke requirements-analyst -> requirements.md
4. Quality Gate 1: Requirements approval
5. Conduct pre-mortem (include statistician perspective)
6. Quality Gate 2: Pre-mortem completion
7. Invoke systems-architect -> architecture.md
8. Quality Gate 3: Architecture approval
9. Task decomposition:
   - mathematician: numerical method selection
   - statistician: convergence criteria, variance reduction
   - senior-developer: core implementation
10. Implementation with progress monitoring
11. Quality Gate 4: Code review (automated + human)
12. Quality Gate 5: Test pass
13. Create PR with conventional commit
14. Quality Gate 6: PR merge
15. Post-merge verification prompt
16. Cleanup session directory (on success)
