Docs Builder

Documentation Architecture Skill

Create or reorganize /docs following a 5-tier hierarchy:

/docs
├── 00-context/              # WHY and WHAT EXISTS RIGHT NOW
├── 01-product/              # WHAT the product must do
├── 02-features/             # HOW features are designed & built
├── 03-logs/                 # MEMORY (what changed over time)
├── 04-process/              # HOW to work with this system
├── archive/                 # Old/unclear docs preserved here
└── README.md                # Navigation guide

Step 1: Detect Mode

Check if /docs exists and has content:

find docs -name "*.md" 2>/dev/null | wc -l

• 0 files → Fresh Mode (skip to Step 3)
• 1+ files → Existing Mode (continue to Step 2)

Step 2: Existing Mode - Analyze First

2.1 Inventory

List all markdown files:

find docs -name "*.md" -exec wc -l {} \; | sort -n

2.2 Read and Categorize

For each file, read first 50-100 lines and categorize:

2.3 Categorization Heuristics

Likely KEEP/MOVE:

• Filename contains: GUIDE, REFERENCE, HOWTO, ARCHITECTURE, COMMANDS, TROUBLESHOOTING, QUICKSTART
• Content: Has TOC, structured sections, explains "how to" or "what is"
• Purpose: Teaches something reusable

Likely ARCHIVE:

• Filename contains: REPORT, STATUS, SUMMARY, FIX_, PHASE_, SPRINT_, _LOG, DRAFT, WIP, OLD, TEMP
• Filename has dates: 2024-01-15-meeting.md
• Located in: archive/, old/, reports/, fixes/, phases/
• Content: Dated entries, task IDs, one-time status updates
• Under ~20 lines and looks like placeholder

When uncertain → ARCHIVE (can always recover later)

2.4 Present Plan to User

Before making changes, show categorization:

KEEP → Move to new structure (X files):
- guides/COMMANDS.md → 02-features/cli/COMMANDS.md
- reference/CONFIG.md → 04-process/reference/CONFIG.md
...

CONSOLIDATE (X groups):
- architecture.md + ARCHITECTURE.md → 00-context/system-state.md
...

ARCHIVE (X files):
- PHASE1_STATUS.md
- FIX_SUMMARY_2024.md
- reports/old-metrics.md
...

Wait for user approval before proceeding.

2.5 Execute Reorganization

1. Create directory structure (including archive):

mkdir -p docs/{00-context,01-product,02-features,03-logs,04-process,archive}

2. Move ARCHIVE files first:

mv docs/old-file.md docs/archive/

3. Move KEEP files to appropriate tiers

4. For CONSOLIDATE: read both files, merge content into new file, move originals to archive

5. Remove empty old directories

Step 3: Create Structure

3.1 Create Directories

mkdir -p docs/{00-context,01-product,02-features,03-logs,04-process,archive}

3.2 Required Files

Create these files (see references/templates.md for content):

00-context/ (4 files):

• blueprint.md - Overarching project artifact (see below)
• vision.md - Product purpose & boundaries
• assumptions.md - Constraints, risks, unknowns
• system-state.md - What's currently built

01-product/ (1 file):

• prd.md - Product requirements

02-features/ (per feature):

• feature-<name>/ subdirectories as needed
• Or flat files for simpler projects

03-logs/ (5 files):

• implementation-log.md
• decisions-log.md
• bug-log.md
• validation-log.md
• insights.md

04-process/ (3+ files):

• dev-workflow.md
• definition-of-done.md
• llm-prompts.md

Root:

• README.md - Navigation guide

Step 4: Populate Files

Content Sources

Pull content from:

• Project README.md
• Package files (package.json, pyproject.toml)
• Existing code comments/docstrings
• Existing docs being reorganized

For Existing Mode

When moving files:

• Update any internal links to match new locations
• Merge duplicate content thoughtfully
• Preserve useful information, don't just copy-paste

Step 5: Integration

If CLAUDE.md exists: Add or update documentation pointer:

## Documentation
See `docs/README.md` for full documentation structure.

If KNOWLEDGE_BASE.md exists: Update to reference new structure with quick links.

Step 6: Validate

# Check structure exists
ls -la docs/{00-context,01-product,02-features,03-logs,04-process,archive}

# Verify minimum files
test -f docs/00-context/blueprint.md && echo "✓ blueprint.md"
test -f docs/00-context/vision.md && echo "✓ vision.md"
test -f docs/00-context/system-state.md && echo "✓ system-state.md"
test -f docs/01-product/prd.md && echo "✓ prd.md"
test -f docs/README.md && echo "✓ README.md"

# Count files per tier
find docs/00-context -name "*.md" | wc -l  # >= 4
find docs/03-logs -name "*.md" | wc -l     # >= 5
find docs/04-process -name "*.md" | wc -l  # >= 3

Blueprint: The Overarching Project Artifact

docs/00-context/blueprint.md is the one and only high-level project document. It answers: what is this project, what's built, what's planned, where is it headed.

When to create: Always. blueprint.md is the first file created in 00-context/. It is required for both Fresh and Existing modes.

Content sources:

• Root README.md — project identity, purpose, stats
• package.json / pyproject.toml — tech stack, dependencies
• Existing docs — features implemented vs planned
• Code structure — what modules/packages exist

Structure:

# [Project Name] Blueprint

## Identity
[What this project IS in 2-3 sentences. Sourced from README.]

## Status
| Area | Status | Notes |
|------|--------|-------|
| [feature/module] | implemented / in-progress / planned | [brief] |

## Architecture
[High-level structure: packages, modules, entry points. No ASCII trees — use tables or flat lists.]

## Implemented
[What works today. Group by feature area. Be specific.]

## Planned
[What's next. Ordered by priority. Include design docs if they exist.]

## Future Direction
[Where does this project want to be? North star. 3-5 bullets max.]

## Key Decisions
[Major architectural choices already made. Link to decisions-log if it exists.]

Rules for blueprint.md:

• Keep it under 150 lines — it's an overview, not a manual
• Update it when features ship or plans change
• It is the FIRST document a new contributor or LLM should read
• No duplication with vision.md (vision = WHY, blueprint = WHAT + WHERE)

Rules

DO:

• Read files before categorizing (don't guess from filename alone)
• Present plan to user before bulk changes
• Archive instead of delete
• Complete one section before moving to next
• Populate files with real content (not empty templates)
• Preserve original files in archive when consolidating

DON'T:

• Delete any files (archive instead)
• Move files without reading them first
• Make bulk changes without user approval
• Create empty placeholder files
• Skip the analysis phase for existing docs

Success Criteria

✅ Mode correctly detected (fresh vs existing) ✅ For existing: categorization presented and approved ✅ All 5 tier directories created (+ archive) ✅ Minimum files in each tier ✅ Files populated with project-specific content ✅ Archive contains old/unclear docs (not deleted) ✅ docs/README.md with navigation ✅ Validation checks pass
