Key Files

File	Purpose
install.js	Main installer - generates and installs workflow files to AI tool directories
src/plan2code-*.md	Source workflow prompts (the "source of truth")
scripts/validate-char-count.js	Pre-commit validator ensuring all source prompts ≤ 11,000 chars
version.json	Version metadata (name, version, description)
QUICK-REFERENCE.md	User quick-reference card
src/statusline-claude/	Claude CLI status bar (included in A Install All + dev tools; also via Custom → S)

Workflow Prompts (in src/)

File	Step	Purpose
plan2code-init.md	Init	Generate AGENTS.md as index + .agents-docs/ section files (progressive discovery)
plan2code-init-update.md	Update	Update AGENTS.md with learnings; detects and routes edits to .agents-docs/ files
plan2code-quick-task.md	0	Lightweight planning for small tasks
plan2code-1-plan.md	1	Requirements analysis & architecture
plan2code-1b-revise-plan.md	1b	Mid-implementation revisions
plan2code-2-document.md	2	Create implementation specs
plan2code-3-implement.md	3	Execute implementation (phase by phase)
plan2code-review.md	review	Post-implementation comprehensive review
plan2code-4-finalize.md	4	Validate, summarize, feedback, archive (7 steps)
plan2code-handoff.md	handoff	Compact the conversation into a self-contained handoff document

Naming Convention

Workflow files follow a strict naming pattern:

• Utilities: plan2code-<name>.md (single dash)
• Numbered steps: plan2code-<N>-<name>.md (single dash, number, single dash)

Examples:

• plan2code-init.md (utility)
• plan2code-1-plan.md (step 1)
• plan2code-1b-revise-plan.md (step 1b)

Reference Files

Some workflows use companion reference files for depth that exceeds the 11k char limit. The orchestrator (main workflow file) loads them via Read directives during execution.

Pattern: src/<source-filename-without-extension>-references/ (e.g., plan2code-review-references/)

How the installer handles them:

• Skill-directory platforms (Claude Code, Agents, Crush, Devin): reference files are nested as <skill-name>/references/. Read paths use canonical references/<file>.md.
• Flat-file platforms (Windsurf, Cursor, Copilot, Continue): reference files are placed as a sibling directory. The installer rewrites Read paths to the sibling directory name (e.g., plan2code-review-references/<file>.md).
• TOML platforms (Gemini CLI): reference files are skipped — TOML embeds content inline, so Read directives won't resolve. The orchestrator's inline fallback text covers this.

Reference files are NOT subject to the 11,000 character limit. Currently only the review workflow uses this pattern — it serves as the POC for potential adoption by other workflows.

Repo-Local Skills (.claude/skills/)

Maintainer-only Claude Code skills committed to the repo but deliberately excluded from install.js — they are dev tooling, not shipped product, so they never install to ~/.claude/skills/ and carry no version bump of their own (a product-version bump would wrongly imply a user-facing release); changelog mentions fold into the current version's entry.

• plan2code-publish/ — cuts a GitHub Release from the top CHANGELOG.md entry once CHANGELOG.md / version.json / package.json agree and the version is ahead of the latest published release. Delegates tag creation to gh release create --target main.

Warning: anything named plan2code-* placed under ~/.claude/skills/ is deleted by the installer's uninstall (uninstallFiles() in install.js) and by every re-install's pre-copy cleanup in install() (both match /^plan2code-/ for the Claude Code skills target). Keep these skills repo-local only.

Status Line

Optional Claude Code status bar living in src/statusline-claude/. Three-line bar (icon + content per line) showing model, project, branch, uncommitted diff stats, session duration + cost, context window usage, and plan/quota usage.

Design constraints:

• Zero runtime dependencies — statusline.js is self-contained (config loader, git helpers, formatters, render). Copied verbatim to ~/.claude/plan2code-statusline.js on install; no bundler step.
• Stdin-driven — all data comes from Claude Code's stdin JSON (model, workspace, context_window, rate_limits, cost). No API calls, no auth, no background processes.
• Silent failure — outer try/catch around main() plus process.exit(0) on missing stdin guarantees the script never crashes the CLI. All git ops are timeout-bounded (1.5s) and non-git workspaces short-circuit via fs.existsSync('.git').
• Atomic settings writes — installer writes ~/.claude/settings.json via temp file + rename so a crash never leaves the file truncated.
• Custom-config respect — installer detects non-plan2code statusLine entries, prompts before replacing, and backs up to statusline-previous.json. Uninstall only removes settings.statusLine if it points to the plan2code bundle.

Layout:

src/statusline-claude/
├── statusline.js           # Self-contained: config, git, formatters, render
├── statusline-config.json  # Default config template
└── README.md               # User docs: install, config, debugging

Adaptive plan-usage display: the formatter auto-selects between 5h/7d rate-limit percentages (Pro/Max/Teams — when rate_limits present in stdin) and Nk in · Nk out session-token counts (Bedrock/Vertex/PAYG — when rate_limits absent). Segment is hidden when neither shape is available.

Installer integration lives in install.js under the STATUS LINE INSTALLATION section (installStatusLine, uninstallStatusLine). Included in A (Install All + dev tools); also available individually via Custom → S.
