How to install Skills (mattpocock) in Codex
In Codex, ask the built-in skill installer for it:
$skill-installer install the <skill> skill from https://github.com/mattpocock/skillsType this in Codex and replace <skill> with a folder name from 'What it contains'. $skill-installer is the skill installer built into Codex, and it downloads the skill from GitHub. Restart Codex if the skill doesn't show up. Check the repo README for any setup it needs. Source: Codex skills docs.
Or copy the skill folder (the one with SKILL.md) into ~/.agents/skills to use it in every project, or into .agents/skills in a repo to share it with that repo. Codex picks up new skills automatically. (where Codex loads skills)

What it contains
Skills (38)
ask-matt— Ask which skill or flow fits your situation. A router over the skills in this repo.code-review— Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes: Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/spec asked for?). Runs both reviews…codebase-design— Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, find deepening opportunities, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module…diagnosing-bugs— Diagnosis loop for hard bugs and performance regressions. Use when the user says "diagnose"/"debug this", or reports something broken/throwing/failing/slow.domain-modeling— Build and sharpen a project's domain model. Use when discussing codebase terminology, writing or editing a GLOSSARY.md, or recording or editing an ADR.grill-with-docs— A relentless interview to sharpen a plan or design, which also creates docs (ADR's and glossary) as we go.implement-spec— Implement the result of /to-spec and /to-tickets in code.implement— Implement a piece of work based on a spec or set of tickets.improve-codebase-architecture— Scan a codebase for deepening opportunities, present them as a visual HTML report, then grill through whichever one you pick.pr— Use when writing a PR body.prototype— Build a throwaway prototype to answer a design question. Use when the user wants to sanity-check whether a state model or logic feels right, or explore what a UI should look like.research— Investigate a question against high-trust primary sources and capture the findings as a Markdown file in the repo. Use when the user wants a topic researched, docs or API facts gathered, or reading legwork delegated to a background agent.retro— Conduct a retrospective on a coding session.setup-matt-pocock-skills— Configure this repo for the engineering skills: set up its issue tracker, triage label vocabulary, and domain doc layout. Run once before first use of the other engineering skills.tdd— Test-driven development. Use when the user wants to build features or fix bugs test-first, mentions "red-green-refactor", or wants integration tests.to-spec— Turn the current conversation into a spec and publish it to the project issue tracker: no interview, just synthesis of what you've already discussed.to-tickets— Break a plan, spec, or the current conversation into a set of tracer-bullet tickets, each declaring its blocking edges, published to the configured tracker (edges as text in one file per ticket locally, or native blocking links on a real tracker).triage— Move issues and external PRs through a state machine of triage roles, categorise, verify, grill if needed, and write agent-ready briefs.wayfinder— Plan a huge chunk of work (more than one agent session can hold) as a shared map of decision tickets on your issue tracker, and resolve them one at a time until the way to the destination is clear.wizard— Generate an interactive bash wizard that walks a human through steps only they can perform. Use when provisioning infrastructure, setting up credentials or CI secrets, walking an unfamiliar third-party dashboard, or running a one-off migration or cutover…chief-of-staff— Pursue a long-running goal in a single session by co-ordinating subagents.claude-handoff— Hand the current conversation off to a fresh background agent that picks up the work immediately.loop-me— Grill me about specs for the workflows I want to build, within this workspace.setup-ts-deep-modules— Wire dependency-cruiser into a TypeScript repo so each package is a deep module, with implementation hidden in subfolders and reachable only through its entry-point files. User-invoked.writing-beats— Writing, exploit; assemble raw material into a journey of beats, grounding each term before a beat leans on it.writing-fragmentswriting-shapegit-guardrails-claude-codemigrate-to-shoehorn— Migrate test files from `as` type assertions to @total-typescript/shoehorn. Use when user mentions shoehorn, wants to replace `as` in tests, or needs partial test data.scaffold-exercisessetup-pre-commitgrill-me— A relentless interview to sharpen a plan or design.grillinghandoff— Compact the current conversation into a handoff document for another agent to pick up.teachto-questionnairewait-whatwriting-for-agents
