What is it?

This repository is a set of small, composable agent skills written by Matt Pocock for everyday software engineering with coding agents. Each skill is a SKILL.md file that an agent can invoke, either directly by the user with a slash command or automatically when a task fits. The skills are grouped into engineering and productivity categories.

The skills target common failure modes of coding agents: misunderstanding what the user wants, verbose and jargon-heavy output, code that is not checked by tests, and codebases that grow messy over time. Examples include /grill-me for interviewing the user about a plan, /grill-with-docs for building a shared glossary and ADRs, /tdd for red-green-refactor development, and /diagnosing-bugs for a phased debugging loop.

Installation depends on the agent. Claude Code, Codex and GitHub Copilot can install it as a plugin that updates itself, while other agents can copy editable files via the skills.sh installer. Running /setup-matt-pocock-skills once per repo configures the issue tracker, triage labels and docs location.

Key features

  • 01Grilling skills that interview you about a plan until the design is clear
  • 02TDD skill built around a red-green-refactor loop
  • 03Phased debugging skill for hard bugs and performance regressions
  • 04Shared glossary and ADR updates during domain modeling
  • 05Two-axis code review comparing diffs against coding standards and the spec
  • 06Works with multiple agents including Claude Code, Codex, Copilot and Gemini CLI

Use cases

  • Aligning with a coding agent on requirements before starting a feature
  • Running test-driven development with an agent on a TypeScript or other project
  • Diagnosing hard-to-reproduce bugs through a structured feedback loop
  • Planning large multi-session refactors as a shared set of tickets

Quick start

  1. 1

    Install the skills in Claude Code

    claude plugin install mattpocock-skills@claude-plugins-official
  2. 2

    Run the setup skill once per repo in your agent

    /setup-matt-pocock-skills

Things to know

  • The skills are prompt-based workflows for coding agents, not a standalone application, so they need an agent like Claude Code or Codex to use.
  • Manual-install agents must update the files by hand and cannot receive automatic updates.
