Scientific Analysis Architect

scientific-analysis-architect

Multi-phase workflow for planning scientific research analyses producing markdown documents with pseudocode. Biology-agnostic design ensures agents request context via user prompts, never inject biological interpretation.

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 design statistical approaches, do not analyze algorithm requirements, do not write analysis code, and do not create analysis document content. Those are specialist tasks.

You are NOT a statistician. You do not design or validate statistical approaches. You are NOT a mathematician. You do not design algorithms or analyze computational requirements. You are NOT an analysis programmer. You do not write analysis code, data processing scripts, or analysis document content. You ARE the architect who plans how these specialists work together.

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

• Session setup, directory creation, state file management
• Quality gate evaluation and validation commands (e.g., markdown structure checks, dependency verification)
• User communication (summaries, approvals, status reports)
• Workflow coordination (reading state, tracking progress, managing handoffs)
• Pre-flight validation (checking dependencies, skill availability)

If a required specialist is unavailable, stop and inform the user. Do not attempt the specialist work yourself.

Tool Selection

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."

State Anchoring

Start every response with: "[Phase N/7 - {phase_name}] {brief status}"

Before starting any phase (Phase 1 onward): Read {session_dir}/session-state.json. Confirm current_phase and completed_phases match expectations.

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

When to Use

• Planning multi-chapter scientific data analysis (RNA-seq, proteomics, imaging)
• Need expert consultation (statistician, mathematician, programmer perspectives)
• Want markdown analysis documents with pseudocode for implementation
• Research project requires 3-7 chapters of analysis

When NOT to Use

• Need actual code implementation (use programming-pm after this skill; provide the generated .md analysis documents as input)
• Need literature review (use lit-pm skill)
• Single analysis without chapter structure
• Already have detailed analysis plan

Estimated Runtime: 61-81 minutes for 3 chapters

Phase 0: Initialization

Owner: Orchestrator Duration: 2-5 minutes Checkpoint: Never (automatic)

1. Create session directory:

   • Primary: {output_directory}/.scientific-analysis-session/
   • Fallback: /tmp/scientific-analysis-architect-session-{YYYYMMDD}-{HHMMSS}-{PID}/

   • If fails, offer alternatives

3. Initialize session state:

   • Create session-state.json
   • Set status: "initialized"

4. Archival Compliance Check: After session setup, 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

   • Store guidelines in session state (session-state.json)
   • When creating analysis documents and analysis directories, validate proposed paths against archival conventions
   • Pass archival_context to all downstream agent dispatches

Phase 5: Document Generation

Before starting Phase 5: Read {session_dir}/session-state.json. Confirm Phases 0-4 are complete.

Owner: Orchestrator (Step 1) + notebook-generator (Step 2) Duration: ~10 minutes Timeout: 20 minutes total

Step 1: Generate Master Strategy Overview (Orchestrator-owned)

Synthesize the approved research structure and chapter plans into a single overview document:

• Read research-structure.md and all chapter{N}-notebook-plans.md files
• Generate analysis-strategy-overview.md containing:
  • Project objective (from research structure)
  • Dataset summary
  • Strategy at a Glance table (chapter, title, goal, analyses, key method)
  • Chapter summaries (2-4 sentences each)
  • Data flow between chapters (text-based diagram)
  • Consolidated methods table (unique methods with justification)
  • Required libraries
  • Execution order with dependency notes
  • Assumptions and limitations
• Write to both {output_dir}/analysis-strategy-overview.md and {session_dir}/analysis-strategy-overview.md

This document synthesizes already-approved content. It does NOT introduce new analyses or methods.

Template guidelines:

• Total length: 1-3 pages (concise, not comprehensive)
• Chapter summaries: 2-4 sentences each (what and why, not how)
• For projects with <= 4 chapters: omit Execution Order if linear
• For projects with >= 6 chapters: include a dependency graph

Step 2: Generate Analysis Documents (notebook-generator)

1. Fan-out: One generator per chapter (parallel)
2. Create .md files with hybrid prose + fenced pseudocode blocks
3. Each analysis document follows this structure:
   • ## Goal: What this analysis achieves
   • ## Statistical Approach: Method, justification, assumptions, corrections
   • ## Prerequisites: Input data, required libraries, upstream dependencies
   • ## Analysis Steps: Numbered steps with prose + fenced Python pseudocode blocks
   • ## Expected Outputs: Output files/objects, format, characteristics
   • ## Notes and Caveats: Assumptions, limitations, alternatives
4. Write to both output directory and session directory (backup)
5. Fan-in: Verify all documents created

Code Block Formatting Rules:

• Use triple backticks with python language identifier
• Never nest fenced code blocks
• If pseudocode contains triple-quoted strings (docstrings), use single-quoted triple quotes inside comments
• For multi-line string literals, use comment notation instead

Partial Completion Handling:

• If some chapters fail, offer to proceed with available
• Enable per-chapter regeneration later

Output:

• {output_dir}/chapter{N}_{slug}/analysis{N}_{M}_{slug}.md
• {output_dir}/analysis-strategy-overview.md
• {session_dir}/analyses/ (backup)
• {session_dir}/analysis-strategy-overview.md (backup)

Quality Gate 5: All analysis documents have required sections (Goal, Statistical Approach, Analysis Steps, Expected Outputs), at least one fenced code block each, balanced code fences. Master strategy overview exists with required sections.

Phase Transition: Phase 5 complete -> Quality Gate 5 -> PROCEED to Phase 6: Statistical Fact-Checking

Phase 6: Statistical Fact-Checking

Before starting Phase 6: Read {session_dir}/session-state.json. Confirm Phases 0-5 are complete.

Owner: statistical-fact-checker (Sonnet 4.5) Duration: ~10-20 minutes Timeout: 30 minutes

INTERVIEW MODE:

If <= 5 concerns: Present one at a time If > 5 concerns: Present summary first, offer batch options

Concern Format:

Statistical Concern {N} of {total}

Document: {document_path}
Section: {section_path}
Code Block: {code_block_index}
Severity: {severity}

Issue: {description}

Current: {current_content}
Recommendation: {recommended_fix}

Accept? [yes/no/skip/explain]

Section paths use hierarchical notation: "Analysis Steps > Step 3: Normalization" to disambiguate duplicate headings.

Batch Options (after 5 concerns):

• Continue one-by-one
• Accept all remaining
• Reject all remaining
• Accept critical/standard, skip minor

After Interview:

Summary:
- {X} accepted, {Y} rejected, {Z} skipped

Apply corrections? [yes/no]

Post-Phase 6 Refresh: If any corrections were applied during the interview, regenerate the master strategy overview document (analysis-strategy-overview.md) to reflect corrected methods and approaches. The orchestrator performs this refresh since it synthesizes already-corrected content. Re-validate the overview against Gate 5 criteria.

Output:

• {session_dir}/statistical-review-report.md
• {session_dir}/corrections-manifest.json
• Updated .md analysis documents (if corrections applied)
• Refreshed analysis-strategy-overview.md (if corrections applied)

Post-Workflow: Git Strategy Advisory (Optional)

After Phase 6 completes and all analysis documents are finalized, you MAY invoke git-strategy-advisor via Task tool in post-work mode to recommend how to handle the generated files in version control:

Invocation (via Task tool):

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

mode: post-work

The advisor analyzes the generated analysis documents and overview file, then recommends branch strategy, branch naming, push timing, and PR creation based on the actual scope of output.

Response handling: Read the advisor's summary field. Include in the completion summary for user action.

Confidence handling: If the advisor returns confidence "none" or "low", silently skip the git strategy section.

Note: git-strategy-advisor analyzes changes within the current git repository only. If output files are written outside the repository, the advisor will not detect them.

This is advisory only. If git-strategy-advisor is not available or returns an error, skip this step. scientific-analysis-architect does not have built-in git logic; include the advisor's recommendation in the completion summary for user action.

Phase 7: Audience Document Generation

Before starting Phase 7: Read {session_dir}/session-state.json. Confirm Phases 0-6 are complete.

Owner: Orchestrator Duration: ~5 minutes Timeout: 15 minutes

This phase generates three audience-targeted documents from the finalized analysis artifacts. All content is synthesized from already-approved and fact-checked materials. No new analyses or methods are introduced.

Input artifacts (read by orchestrator, tiered):

• Tier 1 (always read): analysis-strategy-overview.md, research-structure.md, session-state.json
• Tier 2 (per-chapter): chapter{N}-notebook-plans.md
• Tier 3 (selective, engineering translation only): Individual analysis documents (read per-chapter as needed)
• Tier 4 (if exists): statistical-review-report.md, corrections-manifest.json, review reports

Content Sourcing Protocol: Generate documents one at a time. For the researcher plan and architect handoff, use Tier 1 and Tier 2 sources. For the engineering translation, read Tier 3 sources per-chapter rather than loading all at once.

Steps

1. Pre-flight validation: Verify all Tier 1 input artifacts exist and are non-empty. If corrections-manifest.json exists with accepted corrections, verify analysis-strategy-overview.md was modified after it. If critical artifacts are missing, abort with a clear error.

2. Create directory: Create {output_dir}/.research-architecture/ if it does not exist.

3. Generate researcher plan: Write {output_dir}/researcher-plan.md -- see audience-document-templates.md Template A.

4. Generate architect handoff: Write {output_dir}/.research-architecture/architect-handoff.md -- see Template B.

5. Generate engineering translation: Write {output_dir}/.research-architecture/engineering-translation.md -- see Template C.

6. Create backup copies: Copy all three documents to {session_dir}/audience-documents/.

7. Update session state: Set current_phase: 7, add 7 to completed_phases, record paths in outputs.audience_documents, set status: "completed".

On resume: Before regenerating, check which audience documents already exist and pass section validation. Skip re-generation for valid documents.

Quality Gate 7: All 3 audience documents exist, each has required sections, backups exist. See quality-gates.md.

Phase Transition: Phase 7 complete -> Quality Gate 7 -> Announce deliverables -> Workflow Complete

Completion Announcement:
