# Agent Skills For Real Engineers

My agent skills that I use every day to do real engineering - not vibe coding.

If you want to keep up with changes to these skills, and any new ones I create, you can join ~60,000 other devs on my newsletter:

## Engineering

Skills I use daily for code work.

- **[diagnose](./skills/engineering/diagnose/SKILL.md)** — Disciplined diagnosis loop for hard bugs and performance regressions: reproduce → minimise → hypothesise → instrument → fix → regression-test.

  ```
  npx skills@latest add mattpocock/skills/diagnose
  ```

- **[domain-model](./skills/engineering/domain-model/SKILL.md)** — Grilling session that challenges your plan against the existing domain model, sharpens terminology, and updates `CONTEXT.md` and ADRs inline.

  ```
  npx skills@latest add mattpocock/skills/domain-model
  ```

- **[github-triage](./skills/engineering/github-triage/SKILL.md)** — Triage GitHub issues through a label-based state machine.

  ```
  npx skills@latest add mattpocock/skills/github-triage
  ```

- **[improve-codebase-architecture](./skills/engineering/improve-codebase-architecture/SKILL.md)** — Find deepening opportunities in a codebase, informed by the domain language in `CONTEXT.md` and the decisions in `docs/adr/`.

  ```
  npx skills@latest add mattpocock/skills/improve-codebase-architecture
  ```

- **[tdd](./skills/engineering/tdd/SKILL.md)** — Test-driven development with a red-green-refactor loop. Builds features or fixes bugs one vertical slice at a time.

  ```
  npx skills@latest add mattpocock/skills/tdd
  ```

- **[to-issues](./skills/engineering/to-issues/SKILL.md)** — Break any plan, spec, or PRD into independently-grabbable GitHub issues using vertical slices.

  ```
  npx skills@latest add mattpocock/skills/to-issues
  ```

- **[to-prd](./skills/engineering/to-prd/SKILL.md)** — Turn the current conversation context into a PRD and submit it as a GitHub issue. No interview — just synthesizes what you've already discussed.

  ```
  npx skills@latest add mattpocock/skills/to-prd
  ```

- **[zoom-out](./skills/engineering/zoom-out/SKILL.md)** — Tell the agent to zoom out and give broader context or a higher-level perspective on an unfamiliar section of code.

  ```
  npx skills@latest add mattpocock/skills/zoom-out
  ```

## Productivity

General workflow tools, not code-specific.

- **[caveman](./skills/productivity/caveman/SKILL.md)** — Ultra-compressed communication mode. Cuts token usage ~75% by dropping filler while keeping full technical accuracy.

  ```
  npx skills@latest add mattpocock/skills/caveman
  ```

- **[grill-me](./skills/productivity/grill-me/SKILL.md)** — Get relentlessly interviewed about a plan or design until every branch of the decision tree is resolved.

  ```
  npx skills@latest add mattpocock/skills/grill-me
  ```

- **[write-a-skill](./skills/productivity/write-a-skill/SKILL.md)** — Create new skills with proper structure, progressive disclosure, and bundled resources.

  ```
  npx skills@latest add mattpocock/skills/write-a-skill
  ```

## Misc

Tools I keep around but rarely use.

- **[git-guardrails-claude-code](./skills/misc/git-guardrails-claude-code/SKILL.md)** — Set up Claude Code hooks to block dangerous git commands (push, reset --hard, clean, etc.) before they execute.

  ```
  npx skills@latest add mattpocock/skills/git-guardrails-claude-code
  ```

- **[migrate-to-shoehorn](./skills/misc/migrate-to-shoehorn/SKILL.md)** — Migrate test files from `as` type assertions to @total-typescript/shoehorn.

  ```
  npx skills@latest add mattpocock/skills/migrate-to-shoehorn
  ```

- **[scaffold-exercises](./skills/misc/scaffold-exercises/SKILL.md)** — Create exercise directory structures with sections, problems, solutions, and explainers.

  ```
  npx skills@latest add mattpocock/skills/scaffold-exercises
  ```

- **[setup-pre-commit](./skills/misc/setup-pre-commit/SKILL.md)** — Set up Husky pre-commit hooks with lint-staged, Prettier, type checking, and tests.

  ```
  npx skills@latest add mattpocock/skills/setup-pre-commit
  ```
