build: Skill for Claude Code

Git week

Help the operator with a lightweight weekly git workflow: start a branch per project per week, draft commits for markdown changes, and review recent activity.

This is an opinionated default. If your operator prefers committing directly to main, or uses a different branching convention, swap this skill out.

Triggers

Invoke when the user says:

• "start this week's branch"
• "what did i do today/this week"
• "help me commit"
• "weekly summary"
• "new branch for [project]"

Convention

• Branch format: {project}/week-{YYYY-WW} where YYYY-WW is the ISO 8601 week (date +%G-W%V).
• Merge cadence: weekly, on Fridays (adjust to your own rhythm).
• Active projects: check the workspace AGENTS.md "Active projects" section for the current list.

If the workspace has a GIT-WORKFLOW.md at the repo root, prefer its conventions over the defaults above.

Subtasks

Start a weekly branch

1. Run git branch --list "{project}/week-*" to check if a branch already exists for this week.
2. If not, run: git checkout main && git pull && git checkout -b {project}/week-{YYYY-WW}.
3. Confirm branch created. Remind user to switch back when working on a different project.

If the user says "start all branches", repeat for each active project.

Draft commit messages

1. Run git status to see what's staged or modified.
2. For each changed file, infer the action from the path and filename:
   • docs/YYYY-MM-DD-* → add {date} {description}
   • STATUS.md → update {project} status
   • comms/ → draft {filename without date and extension}
   • decisions/ → add decision: {title}
3. Present one commit command per logical group of changes. Don't batch unrelated files.
4. Ask user to confirm before running.

Weekly activity summary

1. Run: git log --since="last monday" --format="%ad %s" --date=short --all.
2. Group output by date.
3. Present as a clean bullet list, one item per commit, grouped by day.
4. Optionally: offer to turn this into a status update (trigger the status-update skill).
