Grill Memattpocock/skillsA relentless interview to sharpen a plan or design.8.9K2Grillingmattpocock/skillsGrill the user relentlessly about a plan, decision, or idea. Use when the user wants to stress-test their thinking, or uses any 'grill' trigger phrases.8.4K2Grill With Docsmattpocock/skillsA relentless interview to sharpen a plan or design, which also creates docs (ADR's and glossary) as we go.7.7K2Domain Modelingmattpocock/skillsBuild and sharpen a project's domain model. Use when discussing codebase terminology, writing or editing a CONTEXT.md, or recording or editing an ADR.7.2K4Code Reviewmattpocock/skillsReview 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 in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to \"review since X\".7K2Handoffmattpocock/skillsCompact the current conversation into a handoff document for another agent to pick up.7K2Tddmattpocock/skillsTest-driven development. Use when the user wants to build features or fix bugs test-first, mentions "red-green-refactor", or wants integration tests.6.8K4Codebase Designmattpocock/skillsShared 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 vocabulary.6.7K4Improve Codebase Architecturemattpocock/skillsScan a codebase for deepening opportunities, present them as a visual HTML report, then grill through whichever one you pick.6.6K3Diagnosing Bugsmattpocock/skillsDiagnosis loop for hard bugs and performance regressions. Use when the user says "diagnose"/"debug this", or reports something broken/throwing/failing/slow.6.6K3To Specmattpocock/skillsTurn the current conversation into a spec and publish it to the project issue tracker: no interview, just synthesis of what you've already discussed.6.5K2Prototypemattpocock/skillsBuild 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.6.5K4To Ticketsmattpocock/skillsBreak 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).6.4K2Implementmattpocock/skillsImplement a piece of work based on a spec or set of tickets.6.4K2Researchmattpocock/skillsInvestigate 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.6.2K2Setup Matt Pocock Skillsmattpocock/skillsConfigure 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.6.1K7Writing For Agentsmattpocock/skillsWriting documents for agents. Use when creating or editing skills, or modifying AGENTS.md or CLAUDE.md.6.1K3Resolving Merge Conflictsmattpocock/skillsUse when you need to resolve an in-progress git merge/rebase conflict.6.1K2Teachmattpocock/skillsTeach the user a new skill or concept, within this workspace.6.1K6Wayfindermattpocock/skillsPlan 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.6K2Triagemattpocock/skillsMove issues and external PRs through a state machine of triage roles, categorise, verify, grill if needed, and write agent-ready briefs.5.9K4Ask Mattmattpocock/skillsAsk which skill or flow fits your situation. A router over the skills in this repo.5.9K3To Questionnairemattpocock/skillsTurn a decision you can't fully answer into a questionnaire for someone else to fill in.5.8K2Wait Whatmattpocock/skillsStop. That last message did not land: re-pitch it.5.7K2Wizardmattpocock/skillsGenerate 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. Don't invoke this for steps the agent can perform itself.5.5K3Retromattpocock/skillsConduct a retrospective on a coding session.4.5K2Loop Memattpocock/skillsGrill me about specs for the workflows I want to build, within this workspace.4.3K2Claude Handoffmattpocock/skillsHand the current conversation off to a fresh background agent that picks up the work immediately.4.3K2Git Guardrails Claude Codemattpocock/skillsSet up Claude Code hooks to block dangerous git commands (push, reset --hard, clean, branch -D, etc.) before they execute. Use when user wants to prevent destructive git operations, add git safety hooks, or block git push/reset in Claude Code.4.3K3Writing Shapemattpocock/skillsWriting, exploit: shape raw material into an article, paragraph by paragraph.4.3K2Setup Pre Commitmattpocock/skillsSet up Husky pre-commit hooks with lint-staged (Prettier), type checking, and tests in the current repo. Use when user wants to add pre-commit hooks, set up Husky, configure lint-staged, or add commit-time formatting/typechecking/testing.4.3K2Writing Beatsmattpocock/skillsWriting, exploit; assemble raw material into a journey of beats, grounding each term before a beat leans on it.4.3K2Writing Fragmentsmattpocock/skillsWriting, explore: mine raw fragments, no structure yet.4.2K2Implement Specmattpocock/skillsImplement a specification in code.4.2K2Setup TS Deep Modulesmattpocock/skillsWire 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.4.2K3Scaffold Exercisesmattpocock/skillsCreate exercise directory structures with sections, problems, solutions, and explainers that pass linting. Use when user wants to scaffold exercises, create exercise stubs, or set up a new course section.4.2K2Migrate To Shoehornmattpocock/skillsMigrate 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.4.2K2Batch Grill Memattpocock/skillsA relentless interview that asks every frontier question at once, round by round.02Cavemanmattpocock/skills>01Decision Mappingmattpocock/skillsTurn a loose idea into a sequenced map of investigation tickets, then drive them to resolution one at a time.01Design An Interfacemattpocock/skillsGenerate multiple radically different interface designs for a module using parallel sub-agents. Use when user wants to design an API, explore interface options, compare module shapes, or mentions "design it twice".02Diagnosemattpocock/skillsDisciplined diagnosis loop for hard bugs and performance regressions. Reproduce → minimise → hypothesise → instrument → fix → regression-test. Use when user says "diagnose this" / "debug this", reports a bug, says something is broken/throwing/failing, or describes a performance regression.02Edit Articlemattpocock/skillsEdit and improve articles by restructuring sections, improving clarity, and tightening prose.

Use when user wants to plan a refactor, create a refactoring RFC, or break a refactor into safe incremental steps.02Reviewmattpocock/skillsReview 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/PRD asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to "review since X".01Ubiquitous Languagemattpocock/skillsExtract a DDD-style ubiquitous language glossary from the current conversation, flagging ambiguities and proposing canonical terms.
