Plugin Task Plan Skill

Role: Domain planning skill for plugin development tasks. Transforms solution outline deliverables into optimized, executable tasks that delegate to existing skills for implementation.

Key Pattern: Skill delegation with optimization - reads deliverables with metadata from solution_outline.md, applies aggregation/split analysis, creates tasks with delegation blocks and dependencies.

Contract Compliance

MANDATORY: All tasks MUST follow the structure defined in the central contracts:

| Contract | Location | Purpose | |----------|----------|---------| | Task Contract | pm-workflow:manage-tasks/standards/task-contract.md | Task structure and optimization workflow |

Non-compliant tasks will be rejected by validation.

CRITICAL: The steps field MUST contain file paths from the deliverable's Affected files section:

# CORRECT - file paths from deliverable
steps:
  - marketplace/bundles/pm-workflow/agents/plan-init-agent.md
  - marketplace/bundles/pm-workflow/agents/solution-outline-agent.md

# WRONG - descriptive text (violates contract)
steps[2]{number,title,status}:
1,Convert plan-init-agent outputs,pending
2,Convert solution-outline-agent outputs,pending

The steps field lists FILES TO MODIFY, not progress tracking entries.

Operation: plan

Input:

| Parameter | Type | Required | Description | |-----------|------|----------|-------------| | plan_id | string | Yes | Plan identifier | | deliverable_number | number | No | Single deliverable number (omit to process all deliverables) |

Process:

Step 1: Load All Deliverables

Read the solution document to get all deliverables with metadata:

python3 .plan/execute-script.py pm-workflow:manage-solution-outline:manage-solution-outline \
  list-deliverables \
  --plan-id {plan_id}

For each deliverable, extract:

• metadata.change_type, metadata.execution_mode, metadata.domain
• metadata.suggested_skill, metadata.suggested_workflow
• metadata.context_skills, metadata.depends
• affected_files, verification

Step 2: Build Dependency Graph

Parse depends field for each deliverable:

• Identify independent deliverables (depends: none)
• Identify dependency chains
• Detect cycles (INVALID - reject)

Step 3: Analyze for Aggregation

For each pair of deliverables, check if they can be aggregated:

• Same change_type?
• Same suggested_skill?
• Same execution_mode (must be automated)?
• Combined file count < 10?
• NO dependency between them? (CRITICAL - cannot aggregate if one depends on other)

Step 4: Analyze for Splits

For each deliverable, check for split requirements:

• execution_mode: mixed → MUST split
• Different concerns within → SHOULD split
• File count > 15 → CONSIDER splitting

Step 4b: Log Optimization Decisions (REQUIRED)

After analyzing each deliverable or deliverable pair, log the decision:

# If aggregating deliverables
python3 .plan/execute-script.py plan-marshall:manage-logging:manage-log \
  work {plan_id} INFO "[OPTIMIZATION] (pm-plugin-development:plugin-task-plan) Aggregating D{N}+D{M}: same skill ({skill}), no inter-dependency"

# If keeping deliverable separate
python3 .plan/execute-script.py plan-marshall:manage-logging:manage-log \
  work {plan_id} INFO "[OPTIMIZATION] (pm-plugin-development:plugin-task-plan) Keeping D{N} separate: {reason}"

# If splitting deliverable
python3 .plan/execute-script.py plan-marshall:manage-logging:manage-log \
  work {plan_id} INFO "[OPTIMIZATION] (pm-plugin-development:plugin-task-plan) Splitting D{N}: execution_mode=mixed"

This logging is REQUIRED for audit trail and debugging.

Step 5: Create Optimized Tasks

For aggregated deliverables or single deliverables, create tasks using heredoc.

CRITICAL: The steps field MUST contain file paths copied from the deliverable's Affected files section.

python3 .plan/execute-script.py pm-workflow:manage-tasks:manage-tasks add \
  --plan-id {plan_id} <<'EOF'
title: {Action Verb} {Target}: {Scope}
deliverables: [{n1}, {n2}, {n3}]
domain: plan-marshall-plugin-dev
phase: 5-execute
description: |
  {combined description from deliverables}

steps:
  - marketplace/bundles/{bundle}/agents/{file1}.md
  - marketplace/bundles/{bundle}/agents/{file2}.md
  - marketplace/bundles/{bundle}/commands/{file3}.md

depends_on: {TASK-N | none}

delegation:
  skill: {suggested_skill from deliverable metadata}
  workflow: {suggested_workflow from deliverable metadata}
  context_skills: {context_skills from deliverable metadata - MUST include even if empty []}

verification:
  commands:
    - {verification.command from deliverable}
  criteria: {verification.criteria from deliverable}
EOF

Field mapping from deliverable to task:

| Deliverable Field | Task Field | Required | |-------------------|------------|----------| | Affected files: list | steps: list (copy file paths directly) | Yes | | metadata.suggested_skill | delegation.skill | Yes | | metadata.suggested_workflow | delegation.workflow | Yes | | metadata.context_skills | delegation.context_skills | Yes (even if empty []) | | metadata.depends | Used to compute depends_on | Yes | | Verification.Command | verification.commands | Yes | | Verification.Criteria | verification.criteria | Yes |

CRITICAL: The context_skills field MUST always be included in the delegation block, even when empty. Tasks without this field violate the task-contract and will fail validation.

Example with real paths:

python3 .plan/execute-script.py pm-workflow:manage-tasks:manage-tasks add \
  --plan-id migrate-json-to-toon <<'EOF'
title: Migrate pm-workflow Agents to TOON Format
deliverables: [2]
domain: plan-marshall-plugin-dev
phase: 5-execute
description: |
  Convert all JSON output blocks to TOON format in pm-workflow agents.

steps:
  - marketplace/bundles/pm-workflow/agents/plan-init-agent.md
  - marketplace/bundles/pm-workflow/agents/solution-outline-agent.md
  - marketplace/bundles/pm-workflow/agents/task-plan-agent.md
  - marketplace/bundles/pm-workflow/agents/task-execute-agent.md

depends_on: TASK-1

delegation:
  skill: pm-plugin-development:plugin-maintain
  workflow: update-component
  context_skills: []

verification:
  commands:
    - grep -r '```json' marketplace/bundles/pm-workflow/agents/
  criteria: Returns no matches (exit code 1)
EOF

Step 6: Record Issues as Lessons

On ambiguous deliverable or planning issues:

python3 .plan/execute-script.py plan-marshall:manage-lessons:manage-lesson add \
  --component "pm-plugin-development:plugin-task-plan" \
  --category improvement \
  --title "{issue summary}" \
  --detail "{context and resolution approach}"

Valid categories: bug, improvement, anti-pattern

Step 7: Return Results

Output:

status: success
plan_id: {plan_id}

optimization_summary:
  deliverables_processed: {N}
  tasks_created: {M}
  aggregations: {count of deliverable groups}
  splits: {count of split deliverables}

tasks_created[M]{number,title,deliverables,depends_on}:
1,Create skill: java-logging-patterns,[1],none
2,Update plugin-maintain,[2 3],TASK-1
3,Refactor bundle structure,[4],none

lessons_recorded: {count}

Delegation Mapping

When creating tasks, map from deliverable metadata to stdin TOON fields:

| Deliverable Metadata | TOON Field | |---------------------|------------| | domain | domain: | | suggested_skill | delegation: skill: | | suggested_workflow | delegation: workflow: | | context_skills | delegation: context_skills: (merged from all aggregated deliverables) | | affected_files | steps: (one per file) | | verification.command | verification: commands: (may consolidate) | | verification.criteria | verification: criteria: |

Plugin-Specific Skill Mapping

| Change Type | Component Type | Skill | Workflow | |-------------|----------------|-------|----------| | create | skill | pm-plugin-development:plugin-create | create-skill | | create | command | pm-plugin-development:plugin-create | create-command | | create | agent | pm-plugin-development:plugin-create | create-agent | | create | bundle | pm-plugin-development:plugin-create | create-bundle | | modify | any | pm-plugin-development:plugin-maintain | update-component | | refactor | any | pm-plugin-development:plugin-maintain | refactor-structure | | migrate | format | pm-plugin-development:plugin-maintain | update-component | | delete | any | pm-plugin-development:plugin-maintain | remove-component |

Task Generation Patterns

These patterns show how to create tasks for different operation types. Note that steps always contains FILE PATHS.

Create Component Task

Deliverable: "Create new {skill|command|agent} for {purpose}"

The steps field lists files that WILL BE CREATED:

title: Create skill: java-logging-patterns
steps:
  - marketplace/bundles/pm-dev-java/skills/java-logging-patterns/SKILL.md
delegation:
  skill: pm-plugin-development:plugin-create
  workflow: create-skill

Modify Component Task

Deliverable: "Update {component} to {change description}"

The steps field lists existing files to MODIFY:

title: Update plugin-maintain Skill
steps:
  - marketplace/bundles/pm-plugin-development/skills/plugin-maintain/SKILL.md
delegation:
  skill: pm-plugin-development:plugin-maintain
  workflow: update-component

Migrate Task (Multiple Files)

Deliverable: "Migrate {components} to {new format}"

The steps field lists ALL files to migrate (copied from Affected files):

title: Migrate pm-workflow Agents to TOON Format
steps:
  - marketplace/bundles/pm-workflow/agents/plan-init-agent.md
  - marketplace/bundles/pm-workflow/agents/solution-outline-agent.md
  - marketplace/bundles/pm-workflow/agents/task-plan-agent.md
  - marketplace/bundles/pm-workflow/agents/task-execute-agent.md
delegation:
  skill: pm-plugin-development:plugin-maintain
  workflow: update-component

Script Task (Special Case)

Scripts are created within skills. The steps lists the script file AND its test:

title: Create script: manage-references
steps:
  - marketplace/bundles/pm-workflow/skills/manage-references/scripts/manage-references.py
  - test/pm-workflow/manage-references/test_manage_references.py
delegation:
  skill: pm-plugin-development:plugin-create
  workflow: create-skill

Parameter Extraction

When analyzing deliverables, extract these parameters:

For Create Operations

| Parameter | Source | |-----------|--------| | bundle | Explicit in deliverable OR inferred from context | | name | Explicit in deliverable OR derived from purpose | | description | Extracted from deliverable body | | type | Component-specific (agent type, skill type, etc.) |

For Modify Operations

| Parameter | Source | |-----------|--------| | component_path | Explicit path OR resolve from component name | | improvements | Description from deliverable body |

---

Multi-Task Deliverables

Some deliverables require multiple tasks in sequence:

Skill with Scripts

TASK-1: Create skill structure
  - Delegate to: plugin-create → create-skill

TASK-2: Create script(s)
  - Create Python script in skill/scripts/
  - Add test file
  - Update SKILL.md

Command with New Skill

TASK-1: Create supporting skill
  - Delegate to: plugin-create → create-skill

TASK-2: Create command
  - Delegate to: plugin-create → create-command
  - Reference skill from TASK-1

---

Task Dependencies

When creating multiple tasks:

| Dependency | Ordering | |------------|----------| | Scripts within skill | Create skill first, then scripts | | Command referencing skill | Create skill first | | Agent referencing skill | Create skill first | | Refactor before create | Complete refactor first |

---

Error Handling

Ambiguous Deliverable

If deliverable doesn't specify:

• Target bundle → Ask for clarification
• Component type → Infer from keywords or ask
• Operation type → Default to create unless "update/modify/fix" present

Missing Information

If deliverable lacks required parameters:

• Generate task with available info
• Note missing parameters in task description
• Record lesson for future reference

Integration

Caller: pm-plugin-development:plugin-task-plan-agent

Script Notations (use EXACTLY as shown):

• pm-workflow:manage-solution-outline:manage-solution-outline - Read solution and list deliverables (list-deliverables, read)
• pm-workflow:manage-tasks:manage-tasks - Create tasks (add --plan-id X <<'EOF' ... EOF)
• plan-marshall:manage-lessons:manage-lesson - Record lessons on issues (add)
• plan-marshall:manage-logging:manage-log - Log progress (work)

Skills Delegated To:

• pm-plugin-development:plugin-create - Component creation (handles validation and verification internally)
• pm-plugin-development:plugin-maintain - Component updates and refactoring (handles verification internally)
