## Skills

### codex-agent

Delegate coding tasks to OpenAI Codex CLI. Async execution, parallel dispatch, session resume.

- Async task management via `codex-async` wrapper script
- Parallel execution of independent tasks
- Reasoning levels: xhigh (default), high, medium, low
- Sandbox modes: read-only, workspace-write, danger-full-access

### codex-review

Adversarial code review with multi-lens analysis via Codex.

- Three review lenses: Skeptic (bugs), Architect (structure), Minimalist (complexity)
- Verdict system: PASS / CONTESTED / REJECT
- Lead Judgment: accept or reject each finding with rationale
- Manual trigger only (`disable-model-invocation: true`)

### handoff

Session handoff for context preservation across Claude instances.

- Writes `HANDOFF.md` in project root before ending complex sessions
- Template: Current State / What Worked / What Failed / Open Issues / Next Steps
- Overwrites each time — history preserved by git

### ian-gemini-web

Gemini Web image generation with **automatic watermark removal**.

```bash
npx -y bun scripts/main.ts --prompt "A cute cat" --image cat.png
```

- Image generation via Gemini Web
- Automatic watermark removal (Reverse Alpha Blending)
- Models: gemini-3-pro, gemini-2.5-pro, gemini-2.5-flash
- First run opens Chrome for Google authentication

### spec-driven-dev

Spec-driven development lifecycle: design → spec → issue.

- Three phases: design discussion, spec writing, delivery preparation
- Complexity-based routing: simple (direct issue), medium (spec → issue), complex (design → spec → issues)
- Zero dependencies: auto-detects issue tracker (Linear, GitHub, or local fallback)
- Single spec file evolves through lifecycle: `design → spec → ready → implemented`
