Docs-Scaffold — Project Documentation Pipeline (index)

When to use

• Bootstrapping documentation for a new or existing repo (CLAUDE.md, DECISIONS.md, README, runbook, CHANGELOG).
• Auditing gaps in existing docs and generating missing files from KeiSeiKit templates.
• Auto-detecting project type and stack to produce the right starter documentation set.

See _blocks/pipeline-5phase-template.md for the 5-phase wizard contract and _blocks/rule-pure-click-contract.md for the AskUserQuestion rule. Skill-specific phase tables are inline below.

You are bootstrapping or auditing the documentation layer of a repository. The pipeline runs 5 phases in order; each phase owns one concern and has its own verify-criterion. Never skip a phase. Never re-order.

This SKILL.md is the INDEX. Each phase lives in its own file.

Pipeline overview (5 phases)

Phase	File	Purpose	AskUserQuestion
1	phase-1-intake.md	Auto-detect stack + audit existing docs + pick gaps	1×
2	phase-2-scaffold.md	Run kei-docs-scaffold.sh with selected type	1×
3	phase-3-decisions.md	Walk through first ADR (optional)	1×
4	phase-4-diagrams.md	Seed Mermaid architecture starter	1×
5	phase-5-changelog.md	Init CHANGELOG via kei-changelog	1×

Minimum AskUserQuestion count: 5 (one per phase). Phases 3-5 each have an early "Skip this phase" option to keep a lightweight run short.

Variables the pipeline produces

Name	Set in	Meaning
DIR	Phase 1a	Target repo directory (defaults to $PWD)
STACK	Phase 1a	Detected stack label (Rust / Flutter / Node / …)
EXISTING	Phase 1b	Set of docs already present (CLAUDE.md, DECISIONS.md, …)
GAPS	Phase 1c	User-selected subset to scaffold
SCAFFOLDED	Phase 2	Files actually written (could be < GAPS if --force declined)
ADR_N	Phase 3	Number of ADR entries appended (0 if skipped)
DIAGRAMS	Phase 4	Mermaid files seeded (0 if skipped)
CHANGELOG_STATUS	Phase 5	initialized / updated / skipped

Rules (apply throughout)

• Pure-click contract. Every phase has exactly one AskUserQuestion call. Only Phase 1a takes free-text (the target directory path).
• NO DOWNGRADE (RULE -1). If scaffolding fails, return 2-3 concrete alternative paths; never "can't be done".
• NO HALLUCINATION (RULE 0.4). Every primitive / block / template referenced MUST exist on disk. Phase 1 greps before citing. Phase 2 verifies kei-docs-scaffold.sh is executable before invoking.
• Plan Mode First (RULE 0.5). This skill IS the plan. No Edit/Write before the corresponding phase's confirm click.
• Constructor Pattern (RULE ZERO). This SKILL.md stays < 200 LOC. Each phase file < 80 LOC.
• Surgical Changes. Scaffold only creates files; never modifies code. Only touches: CLAUDE.md, DECISIONS.md, docs/runbook.md, README.md, docs/diagrams/*.mmd, CHANGELOG.md. Never edits source.
• Idempotent. Re-runs skip existing files unless --force is passed in Phase 2. No duplicate ADR numbering in Phase 3.
• Public-publish gate. README scaffold refuses to write if the repo is on the banned-public list (see ~/.claude/rules/security.md). User must type "yes, deploy" + "confirm publication" to override.
