/tdd
Drives feature work and bug fixes through a tight failing-test-first loop. Trigger when implementing, fixing, or refactoring behavior in a codebase that already has tests. Skip for spikes, visual-only edits, throwaway scripts, and generated files.

A spec-driven development pipeline for Claude Code and Codex CLI. Refine the spec before you code, let TDD enforce it, verify nothing slipped, then review.

- /diagnose
Turn a bug symptom into a fix with a regression test that locks it down. If the user opens vague ("there's a bug", "/diagnose"), interview them one question at a time until you have enough to attempt a reproduction; if you still cannot reproduce, say so explicitly. Then drive
Open skill - /feature
Kick off the full feature workflow — interview-to-spec, optional spec-approach, tdd, verify, then review — when starting a new feature from scratch. Thin orchestrator: confirms intent in one sentence, then hands off to the first stage and lets each downstream skill activate on
Open skill - /interview-to-spec
Conduct a focused interview to draft a spec.md for an upcoming task (the input step of SDD — spec-driven development). Walks through goal, behaviors, acceptance criteria, edge cases, and out-of-scope one branch at a time, then writes the spec to disk. If during the interview the
Open skill - /spec-approach
Add a refined `## Approach` section to an existing feature spec.md before TDD executes it. Reads the spec, explores the codebase to ground the approach in real modules and patterns, proposes 2–3 alternatives when they exist, validates with the user, then appends `## Approach` to
Open skill - /verify
Verify that a spec.md's Acceptance criteria are observably covered by green tests before opening a PR. Reads the spec, finds the tests that cover each AC, runs the suite to confirm everything green, and reports gaps (uncovered AC, skipped tests, missing edge-case coverage). When
