Update Project Docs

Update Project Docs

Keep CLAUDE.md and AGENTS.md current so future AI sessions start with accurate project context.

When to Trigger

Activate after completing changes that affect how someone navigates or works in the project. Both conditions must hold:

1. The project contains a CLAUDE.md or AGENTS.md (if not, skip)
2. The changes meet the significance threshold below

Significance Threshold

Trigger (update needed):

• New modules, packages, or top-level directories
• Renamed/moved/deleted files that CLAUDE.md references
• Changed build commands, test commands, or tooling
• New conventions or patterns introduced
• API/interface changes affecting documented entry points
• Document structure reorganization (text projects)
• New dependencies that require setup steps

Skip (too small to trigger):

• Bug fixes within existing architecture
• Adding content within existing structure
• Minor refactors (rename variable, extract small helper)
• Test additions following existing patterns
• Typo fixes, formatting changes

Workflow

1. Check for docs — Locate CLAUDE.md or AGENTS.md in the project root. If neither exists, stop.

2. Review what changed — Use git diff or recall the changes just made. Identify which aspects affect project navigation or workflow.

3. Read current docs — Load the existing CLAUDE.md/AGENTS.md to understand its structure and voice.

4. Identify stale/missing sections — Compare the current project state against what the docs describe. Look for:

   • Sections referencing renamed/deleted files
   • Missing entries for new modules or directories
   • Outdated build/test/lint commands
   • Conventions that no longer apply

5. Update — Edit the docs following the Update Principles below. Preserve the existing document style.

6. Show the user — Summarize what was updated and why, so the user can verify the changes make sense.

Update Principles

What to Add

• New module/directory descriptions (one line each)
• Changed build, test, or lint commands
• New conventions or patterns that future sessions should follow
• Setup steps for new dependencies
• Updated file paths for moved/renamed files

What NOT to Add

• Implementation details (that's what code is for)
• Temporary workarounds or TODOs
• Information already obvious from file names
• Content that duplicates README.md

Style Guidelines

• Match existing voice — If the file is terse, stay terse. If it uses full sentences, use full sentences.
• Keep it scannable — Prefer bullet lists over prose paragraphs
• Remove stale info — Deleting outdated content is as important as adding new content. A shorter, accurate file beats a longer, stale one.
• Preserve structure — Add new items to existing sections rather than creating new sections, unless the change introduces an entirely new category.
• Be specific — "Run make test-integration" not "run the integration tests"

Scope

• Update only project-level CLAUDE.md/AGENTS.md, not workspace or global files
• If both CLAUDE.md and AGENTS.md exist, update whichever contains the relevant section (or both if the information belongs in both)
• Never create a CLAUDE.md/AGENTS.md if one doesn't already exist — that's the user's decision
