## Published listings

- [Prd Author](https://agentstack.voostack.com/l/skill-geigermatic-claude-craft-prd-author) — Skill · Free · security-reviewed — `agentstack add skill-geigermatic-claude-craft-prd-author`
  Interactively draft a Product Requirements Document from a problem statement. Walks the user through Problem, Current State, Design, Phases, Files, Metrics, Risks, and a Manual UI Test Checklist. Use when the user has a non-trivial feature, refactor, or initiative that needs alignment before implementation.
- [Verify Claim](https://agentstack.voostack.com/l/skill-geigermatic-claude-craft-verify-claim) — Skill · Free · security-reviewed — `agentstack add skill-geigermatic-claude-craft-verify-claim`
  Turn an assertion ("the API supports X", "this function does Y", "the file is at Z") into runnable evidence. Use when you, the user, or a doc/memory has made a claim that should be verified before acting on it.
- [Pre Merge](https://agentstack.voostack.com/l/skill-geigermatic-claude-craft-pre-merge) — Skill · Free · security-reviewed — `agentstack add skill-geigermatic-claude-craft-pre-merge`
  Run the full pre-merge checklist — tests, lint, build, version bump, doc updates, self-review of the diff. Use before merging any feature branch to main/beta/staging.
- [Doc Audit](https://agentstack.voostack.com/l/skill-geigermatic-claude-craft-doc-audit) — Skill · Free · security-reviewed — `agentstack add skill-geigermatic-claude-craft-doc-audit`
  Sweep docs/ for stale frontmatter, drift between docs and code, and missing audit entries. Use to find documentation rot before it misleads someone.
- [Bug Fix Tdd](https://agentstack.voostack.com/l/skill-geigermatic-claude-craft-bug-fix-tdd) — Skill · Free · security-reviewed — `agentstack add skill-geigermatic-claude-craft-bug-fix-tdd`
  Fix a bug test-first. Reproduce as a failing test before writing the fix. Use when the user reports a bug or asks you to fix a defect.
- [Tdd Slice](https://agentstack.voostack.com/l/skill-geigermatic-claude-craft-tdd-slice) — Skill · Free · security-reviewed — `agentstack add skill-geigermatic-claude-craft-tdd-slice`
  Plan a feature as vertical slices with contract test → implementation → e2e → flag-gated deploy. Use when starting non-trivial customer-facing feature work, especially anything proxying an external service or requiring revert speed.
