Research Pipeline Skill

Purpose

research-pipeline automates the research workflow by chaining five specialized skills in sequence. Instead of manually invoking researcher, synthesizer, devils-advocate, fact-checker, and editor with handoffs between each, this skill runs the whole chain with structured context passing.

This is the "pipeline pattern" for skill orchestration: a predefined sequence of skills that together accomplish a goal requiring several specialized capabilities.

When to Use This Skill

1. Complete research workflow needed: from research question to polished document
2. Quality matters: output must withstand adversarial review and fact-checking
3. Hands-off execution desired: set the goal, receive the final product
4. Standard research pipeline fits: researcher -> synthesizer -> review -> edit matches the need

Clear Indicators for Use

• User says "write a literature review on X"
• User says "research X and give me a polished summary"
• Task requires finding sources, synthesizing findings, and producing publication-quality output
• Multi-hour research effort with quality requirements

When NOT to Use

• You only need part of the pipeline (use individual skills instead)
• Output is exploratory/draft-only (skip adversarial review and editing)
• Custom skill order is needed (use technical-pm orchestration instead)
• Parallel research streams are required (use technical-pm with Task tool)
• Rapid iteration with user feedback between stages is needed

Orchestration stance

You keep the user's original goal intact across the chain and make sure each stage receives the context the previous one produced. The pipeline is a convenience, not a constraint: when a stage fails validation or genuinely needs user input, pause and escalate rather than passing weak output downstream.

Each stage runs as a separate specialist via Task tool. Fan-out conventions: ../references/delegation-and-scope.md.

OUTPUT

| Stage | Skill | Key Output | Quality Gate | |-------|-------|------------|--------------| | 1 | researcher | Literature review draft with citations | Has citations, addresses topic | | 2 | synthesizer | Integrated analysis with themes | Cross-cutting insights present | | 3 | devils-advocate | Strengthened arguments | Challenges addressed or documented | | 4 | fact-checker | Verified citations | All claims have valid citations | | 5 | editor | Polished prose | CLAUDE.md style compliant |

Initializing the pipeline

Parse the user's goal into topic, scope (comprehensive vs focused), constraints (time, page count, focus areas), and a workflow_id.

Archival compliance check

Before creating the pipeline context, read ~/.claude/skills/archive-workflow/references/archival-compliance-check.md and apply its 5-step pattern to file creation. If that file is missing, log a warning and proceed without the archival check.

pipeline:
  archival:
    guidelines_present: true/false
    naming_convention: "{from YAML}"
    output_directory_override: "{if archival says docs go elsewhere}"
    enforcement_mode: "advisory"

When setting the output location (default docs/literature/{topic}/), validate it against the archival structure guidelines. On a violation, present batch advisory options, record the user's choice in the pipeline context, and pass archival_context to every downstream stage.

Initial context

pipeline:
  workflow_id: "research-{uuid}"
  goal: "{user's original goal}"
  topic: "{extracted topic}"
  scope: comprehensive | focused
  constraints:
    max_pages: {N}
    focus_areas: [list]
    time_limit: {hours}
  current_stage: 1
  started_at: "{timestamp}"

The five stages

Each stage is dispatched via Task tool with the previous stage's handoff file path in the prompt. Judge each output against the one-line quality gate in the table above before writing the handoff; the specialists own how they get there.

Stage 1 — researcher. Literature search (PubMed, bioRxiv, OpenAlex), paper notes, draft review with Nature-style citations. If the draft has no citations or misses the topic, pause and offer the user a retry with narrowed scope, acceptance of partial output, or abort.

Stage 2 — synthesizer. Reads the researcher output, identifies cross-cutting themes, surfaces tensions and contradictions, draws project-specific implications. Should add value beyond a summary and carry citations forward.

Stage 3 — devils-advocate. Identifies the thesis, evaluates strategic coherence, challenges thesis-critical claims, proposes counter-arguments, exchanges with the synthesizer for up to 2 rounds. The handoff records which challenges were addressed, which uncertainties remain, and the approval status.

Stage 4 — fact-checker. Inventories quantitative claims and verifies each citation against a real source, checks superscript format, flags missing or wrong citations, and produces a verification report. Minor issues get corrected inline; major ones go back to the synthesizer and are then re-checked.

Stage 5 — editor. Applies CLAUDE.md style guidelines: bullets to prose where appropriate, bridging transitions, glossary placement, final polish for publication.

Optional: git strategy advisory

After the completion report you can invoke git-strategy-advisor via Task tool in post-work mode:

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

mode: post-work

Read the advisor's summary field into the completion report. Skip the section silently if confidence is "none" or "low", if the advisor is unavailable or errors, or if output files were written outside the current git repository (the advisor only sees changes inside it).

Handoff Format

Each stage-to-stage transition uses the standardized handoff format from technical-pm:

handoff:
  version: "1.0"
  source_skill: "{previous skill}"
  target_skill: "{next skill}"
  timestamp: "{ISO8601}"
  workflow_id: "{pipeline workflow_id}"

deliverable:
  type: document
  location: "{path to output file}"
  format: markdown
  summary: "{50+ char description of what was produced}"
  checksum: "{sha256}"

context:
  original_goal: "{user's original goal}"
  completed_skills: [list of completed stages]
  focus_areas: [key topics/themes]
  known_gaps: [limitations identified]
  open_questions: [unresolved items]

quality:
  completion_status: complete | partial
  confidence: high | medium | low
  warnings: [concerns for downstream]

Validate before each handoff: required fields present, summary >= 50 chars, file exists, checksum recomputes and matches. On validation failure, stop the pipeline and report to the user.

Configuration Options

Scope Settings

Comprehensive (default):

• Researcher: Full literature review (8+ papers)
• Synthesizer: Multi-theme analysis

Skipping stages reduces quality guarantees; note skipped stages in the completion report.

Output Location

Default: docs/literature/{topic}/

Override: research-pipeline topic="X" --output="{custom path}"

Error Handling

If a stage fails: keep all previous stage outputs, save the current stage's work-in-progress, stop before the next stage, and report with options.

Pipeline paused: Stage 3 (devils-advocate) failed

Error: Could not identify thesis in synthesizer output

Completed outputs preserved:
- docs/literature/topic/researcher-draft.md
- docs/literature/topic/synthesis.md (partial)

Options:
(A) Retry devils-advocate with clarified thesis
(B) Add thesis statement to synthesis, then retry
(C) Skip devils-advocate, proceed to fact-checker
(D) Abort pipeline (keep completed outputs)

Interruption Recovery

Pipeline state is saved after each stage completes, at /tmp/pipeline-state-{workflow_id}.yaml.

Integration with Other Skills

Use technical-pm instead of research-pipeline when multiple independent research streams need parallel execution, when custom skill ordering is required, when non-research skills belong in the workflow, or when dependency management gets complex.

After the pipeline completes, the user may invoke archive-workflow separately for project organization:

Skill(archive-workflow, project="{project root}")

The pipeline does not invoke archive-workflow automatically — organization decisions stay with the user. It may invoke git-strategy-advisor (via Task tool, not Skill tool) for advisory branch/push/PR recommendations.

Example Invocations

Basic Research Review

User: "Research hepatocyte oxygenation and write a comprehensive literature review"

1. Researcher: reviews 8-10 papers on hepatocyte oxygen consumption
2. Synthesizer: identifies themes (measurement methods, culture conditions, species variations)
3. Devil's Advocate: challenges the assumption that in vitro values apply to bioreactor design
4. Fact-Checker: verifies all K_oA values trace to primary sources
5. Editor: polishes into a CLAUDE.md-compliant document

Output: docs/literature/hepatocyte-oxygenation/review-hepatocyte-oxygenation.md

Focused Summary

User: "Give me a quick summary of hollow fiber bioreactor designs for liver support"

Focused mode: 3-4 key papers, single-theme synthesis, 1 devil's advocate round, critical citations only, essential polish.

Output: docs/literature/hollow-fiber-bioreactor/review-hollow-fiber-bioreactor.md

With Constraints

User: "Research Matrigel alternatives for hepatocyte culture, focus on chemical approaches, max 5 pages"

Topic is Matrigel alternatives for hepatocyte culture, focus is chemical rather than biological approaches, and the 5-page limit propagates: the researcher filters for chemical/synthetic matrix papers, the synthesizer respects the page limit, and every stage honors the focus constraint.

Common Pitfalls

1. Scope creep in researcher stage

   • Symptom: Researcher spends 6+ hours on a "quick summary" request
   • Fix: Set explicit scope at pipeline init (comprehensive vs focused)

2. Thesis drift between stages

   • Symptom: Final document doesn't answer the original question
   • Fix: Handoff includes original_goal; each stage checks alignment

3. Citation format inconsistency

   • Symptom: Mixed citation formats (superscripts and brackets)
   • Fix: Fact-checker enforces format; editor normalizes

4. Skipping stages reduces quality

   • Symptom: Unchallenged arguments, unverified citations in final output
   • Fix: Warn the user when stages are skipped; note it in the completion report

Handoffs

| Condition | Hand off to | |-----------|-------------| | Pipeline complete | User (with completion report) | | Pipeline complete, organization needed | archive-workflow (manual invocation) | | Stage failure, needs diagnosis | User (with error context) | | Custom workflow needed | technical-pm (for flexible orchestration) | | Parallel research streams | technical-pm with Task tool |
