Update Project Docs

Update project docs

Sync project tracking files after completing work, then provide a ready to use git commit message.

Activate with: /update or @update

Step 1: Get real dates and see what changed

Run these together:

git log --date=short -n 10

git diff --stat

Use actual commit dates. Never use placeholder dates or future months. The diff stat tells you which files changed so the changelog and commit message are accurate.

Step 2: Update task.md

Move completed items from ## To Do or ## In Progress into ## Recently Completed with a timestamp:

- YYYY-MM-DD HH:mm UTC - Short description of what was done. PRD: prds/slug.md (if one exists).

If new work is queued, add it under ## To Do.

Step 3: Update changelog.md

Follow https://keepachangelog.com/en/1.0.0/ format. Add the new entry under ## [Unreleased]:

### Added
- What was added with key details (YYYY-MM-DD).

### Changed
- What changed and why (YYYY-MM-DD).

### Fixed
- Bug description and resolution (YYYY-MM-DD).

Use real dates from git log. Add timestamps in parentheses when it helps distinguish same day entries.

Step 4: Update files.md

Only update if new files were added, files were renamed, or existing descriptions are outdated.

• Add new files to the correct section
• Update descriptions for renamed or changed files
• Keep descriptions to one sentence, no emoji

Step 5: Generate a git commit message

After syncing all docs, write a commit message the user can copy and run. Format:

git add -A && git commit -m "$(cat <<'EOF'
<type>: <short summary of the main change>

<optional body: 1-3 bullets covering what changed>
EOF
)"

Type must be one of: feat, fix, docs, style, refactor, test, chore.

Rules for the commit message:

• Present tense ("add feature" not "added feature")
• Subject line under 50 characters
• No period at the end of the subject
• Body bullets only when the change touches more than two concerns
• If the session was purely a docs sync with no code changes, use docs: sync task, changelog, and files

Checklist

Before calling this done:

• git log and git diff --stat run to get real dates and changed files
• task.md updated with completed items and timestamps
• changelog.md new entry added with real dates
• files.md updated if files were added, renamed, or changed
• Git commit message printed for the user to copy

Notes

• This skill applies to this project. If the project does not have these exact files, adapt the steps to whatever tracking files exist.
• Do not create README.md, CONTRIBUTING.md, or other documentation files unless explicitly requested.
• Do not run git commit yourself. Print the command and let the user decide.
