⚠️ Artifacts-only mode: When deploy_mode is artifacts_only, this skill is NOT invoked — the pipeline runner handles this phase deterministically. The instructions below apply only when deploy_mode is live.

Fabric Documentation

Goal: Produce ONE deliverable — docs/project-brief.md — that a CTO can read in 10 minutes.

⚡ Pre-generated brief: The runner writes a structured project-brief.md synthesized from all handoffs before this skill is invoked, with <!-- AGENT: FILL --> markers where narrative polish is needed. Your job: (1) verify facts against the source handoffs, (2) add narrative polish so the brief reads like a CTO memo rather than a template, (3) replace every <!-- AGENT: FILL --> marker.

Instructions

Step 1: Read Pipeline Handoffs

Read these files in parallel from _projects/[name]/docs/ (all are independent inputs):

• discovery-brief.md — problem statement and signals
• architecture-handoff.md — items, waves, decisions, trade-offs, diagram
• deployment-handoff.md — what was deployed, config rationale, manual steps
• test-plan.md — acceptance criteria, edge cases
• validation-report.md — pass/fail results

Step 2: Polish project-brief.md

Edit _projects/[name]/docs/project-brief.md in place (it is pre-generated).

Follow the template in references/documentation-templates.md. Key rules:

1. ~1,500 words max — every fact appears exactly once
2. Decisions inline — as a table in "Why This Architecture", NOT separate ADR files
3. No separate files — do NOT create README.md, architecture.md, deployment-log.md, or decisions/*.md
4. Synthesize, don't copy — distill the handoffs into narrative, don't paste YAML blocks

Step 3: Verify Completeness

The brief must answer these 5 questions:

1. What problem are we solving? (from discovery)
2. What did we build? (items + diagram from architecture)
3. Why this approach? (decisions from architecture)
4. How to deploy it? (from deployment handoff)
5. Did it work? (from validation)

Constraints

• Documents only — no architecture decisions or deployments
• ONE output file: project-brief.md
• Do NOT create README.md, architecture.md, deployment-log.md, or decisions/*.md
