Claude Code Skills

compost

One software-engineering workflow for Claude Code: specs with BDD acceptance criteria, tracer-bullet issues, builds that fit the existing tests, automatic review, and doc pruning.

• build

  Implements one unblocked issue in a worktree and fits its tests into the suite that already exists.

• deepen

  Designs deep modules, meaning small interfaces with a lot of behaviour behind them, seams where something really varies, and tests at the interface.

• deeper-ask

  Makes a request deeper, not bigger, by asking what a top practitioner would do, the rawest material, the methods and tools, and what independent check would...

• diagnose

  Finds a bug's root cause by first building a fast, deterministic check that goes red on it, then testing ranked hypotheses one variable at a time.

• fan-out

  Settles a contested design or an unclear cause by running several independent attempts in parallel, judging them against each other on a rubric, and synthesi...

• finish

  Integrates reviewed work by testing it against the branch it will merge into, opening or updating the pull request, and merging or discarding only on the use...

• implement

  Drives filed issues to a reviewed, draft-PR-ready branch, running build, verify, and review for each issue on its own and working independent issues in paral...

• pause

  Stops work at a safe point with everything committed and a resumable status comment on the parent issue, and picks paused work back up from the tracker and git.

• prune

  Finds doc drift, where documentation says something the code no longer does, and settles it in the code's favour.

• retro

  Looks back over a coding session and files the changes to the agent's environment (checks, pointers, instruction files, tooling, access) that would have made...

• review

  Reviews a verified change with subagents on two axes, Standards and Spec, then works through the findings that survive.

• setup

  Configures a repo once for the compost skills, recording its issue tracker, domain doc layout, core docs, test convention, verify gates, and observability st...

• skill-drift

  Reviews the skill-drift log that the skill-drift mod writes, and turns skills that keep drifting across sessions into draft fixes.

• slice

  Breaks an agreed spec into tracer-bullet issues in the repo's tracker, each with its acceptance criteria, files, interfaces, and blocking edges.

• spec

  Turns a request for new behavior, a fuzzy idea, or a rough doc into an agreed spec of user stories with Given/When/Then acceptance criteria, posted as the pa...

• thin

  Finds tests that no longer earn their place, where every bug they would catch another test already catches, and folds or deletes them on the user's word.

• turn

  Checks the skill repos compost was made from for upstream changes worth working in, and adds skill repos to watch as references.

• verify

  Proves a change works from fresh evidence before anyone says it does.

• wait-what

  Re-pitches whatever the user stopped following, with the premise they missed, in plain words and the glossary's terms.
