What's inside

The instructions your model reads when the skill loads.

Document

Generate documentation for newly implemented features.

Usage

/phx:document .claude/plans/magic-link-auth/plan.md
/phx:document magic link authentication
/phx:document  # Auto-detect from recent plan

Iron Laws

Never remove existing documentation — Existing docs may reflect design intent that isn't obvious from code alone; update rather than replace
@moduledoc on every public module — Undocumented modules accumulate quickly and create onboarding friction for new team members
ADRs capture the "why", not the "what" — Code shows what was built; ADRs explain why this approach was chosen over alternatives
Match @doc to function's public API — Document parameters, return values, and edge cases; callers shouldn't need to read the implementation
DO NOT add @doc to untested code — documentation implies a stable contract; document only after tests confirm the function behaves as described

What Gets Documented

Output	Description
`@moduledoc`	For new modules missing documentation
`@doc`	For public functions without docs
README section	For user-facing features
ADR	For significant architectural decisions

Workflow

Step 0: Pre-check (avoid no-op runs)

Run git diff --name-only HEAD~5 | grep '\.ex$' | head -20 to check for new .ex files.

If NO new .ex files were added (only modifications), skip the full audit and report: "No new modules — documentation coverage unchanged." This prevents 35-message analysis sessions that conclude "PASS" with zero output (confirmed: session bb0a0454 wasted ~2K tokens on no-op).
