# CLAUDE.md

Guidance for Claude Code when working with this repository.

## Project Overview

SDLC Studio is a Claude Code skill for managing the full software development lifecycle - from PRD creation through Epic decomposition, User Story generation, implementation planning, and test automation.

**This is a Claude Code skill** installed to `.claude/skills/sdlc-studio/`.

## Skill Structure

| Path | Purpose |
| ------ | --------- |
| `.claude/skills/sdlc-studio/SKILL.md` | Main entry point (651 lines) |
| `.claude/skills/sdlc-studio/reference-philosophy.md` | Create vs Generate modes - read first |
| `.claude/skills/sdlc-studio/reference-doctrine.md` | Operating doctrine - onboard a Claude to any project (v1.7.0) |
| `.claude/skills/sdlc-studio/reference-outputs.md` | Canonical story and epic completion cascades |
| `.claude/skills/sdlc-studio/reference-project.md` | Full-PRD orchestration (`project plan` and `project implement`) |
| `.claude/skills/sdlc-studio/reference-cr.md` | Change request lifecycle (plus `cr sync` for GitHub) |
| `.claude/skills/sdlc-studio/reference-rfc.md` | RFC design-exploration lifecycle (v1.7.0) |
| `.claude/skills/sdlc-studio/reference-reconcile.md` | Census-based drift detection, `--verify` delegates to verify_ac.py |
| `.claude/skills/sdlc-studio/reference-agentic-lessons.md` | Production patterns plus per-project lessons accumulation |
| `.claude/skills/sdlc-studio/reference-operator-heuristics.md` | Cross-cutting operator patterns for live services (v1.7.0) |

| `.claude/skills/sdlc-studio/reference-plan-files.md` | Claude Code plan-file lifecycle (v1.7.0) |
| `.claude/skills/sdlc-studio/reference-workflow-personas.md` | Three Amigos consultation model |
| `.claude/skills/sdlc-studio/reference-repo-map.md` | AST repo indexer design (v1.6.0) |

| `.claude/skills/sdlc-studio/reference-github-sync.md` | GitHub Issues two-way sync (v1.6.0) |
| `.claude/skills/sdlc-studio/reference-scripts.md` | Scripts directory convention (v1.6.0) |
| `.claude/skills/sdlc-studio/reference-*.md` | Domain-specific workflows (41 files total) |
| `.claude/skills/sdlc-studio/help/` | Type-specific help (28 files) |
| `.claude/skills/sdlc-studio/lessons/` | Cross-project lessons registry (v1.7.0) |
| `.claude/skills/sdlc-studio/templates/` | Document and code templates (70 files) |
| `.claude/skills/sdlc-studio/scripts/` | Skill-internal Python helpers (v1.6.0 - repo_map, verify_ac, github_sync) |
| `.claude/skills/sdlc-studio/best-practices/` | Quality guidelines (15 files) |

## Soft Dependencies (runtime)

Some v1.6.0 features need external tools on PATH:

| Feature | Requires | Notes |
| --- | --- | --- |
| `cr sync`, `story sync`, `project sync` | `gh` CLI authenticated | No PyGitHub dependency; all calls routed through gh |
| `reconcile --verify` | `pytest`, `jest`, `vitest`, `go`, `curl`, `jq`, `rg` (whichever your AC verifiers reference) | Only the tools your Verify lines invoke need to be installed |
| `repo map build` | Python 3.10+ | Pure stdlib; no ctags or tree-sitter needed |

## Testing the Skill

Markdown: `npm run lint` runs markdownlint across all markdown in
the repo.

Scripts: `python3 -m unittest discover -s
.claude/skills/sdlc-studio/scripts/tests` runs the unit tests for
`repo_map.py`, `verify_ac.py`, and `github_sync.py`. All tests must
pass before a release is tagged.

Manual verification:

1. Install: `cp -r .claude/skills/sdlc-studio ~/.claude/skills/`
2. Run `/sdlc-studio help` - displays command reference
3. Run `/sdlc-studio status` - shows pipeline state
4. Run `/sdlc-studio repo map build` - produces .local/repo-map.json
5. Run `/sdlc-studio reconcile --verify --dry-run` against a fixture
   story with Verify lines

## Development Guidelines

When modifying the skill:

- **SKILL.md:** Main entry point (currently 651 lines). Delegate workflow detail to `reference-*.md` rather than inline it.
- **New commands:** Add help file to `help/`, update SKILL.md tables
- **New templates:** Add to `templates/`, update See Also section
- **Workflows:** Update relevant `reference*.md` file

## Style Requirements

- British English (analyse, colour, behaviour)
- No em dashes - use en dash with spaces or restructure
- No corporate jargon (synergy, leverage, robust)
- Dense, economical writing
- `{{placeholder}}` syntax in templates

## Best Practices

Check the relevant guide before creating artifacts:

| Creating... | Check |
| ------------- | ------- |
| Python script | `best-practices/python.md` then `script.md` |
| Bash script | `best-practices/script.md` |
| Documentation | `best-practices/documentation.md` |
| Claude skill | `best-practices/claude-skill.md` |
