Geoff Bremner skills

Ask which skill or flow fits your situation. A router over the skills in this repo. disable-model-invocation: true

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 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".

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 vocabulary.

Diagnosis loop for hard bugs and performance regressions. Use when the user says "diagnose"/"debug this", or reports something broken/throwing/failing/slow.

Build and sharpen a project's domain model. Use when the user wants to pin down domain terminology or a ubiquitous language, record an architectural decision, or when another skill needs to maintain the domain model.

A relentless interview to sharpen a plan or design, which also creates docs (ADR's and glossary) as we go. disable-model-invocation: true

Implement a piece of work based on a spec or set of tickets." disable-model-invocation: true

Scan a codebase for deepening opportunities, present them as a visual HTML report, then grill through whichever one you pick. disable-model-invocation: true

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.

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.

Use when you need to resolve an in-progress git merge/rebase conflict.

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. disable-model-invocation: true

Test-driven development. Use when the user wants to build features or fix bugs test-first, mentions "red-green-refactor", or wants integration tests.

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. disable-model-invocation: true

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. disable-model-invocation: true

Move issues and external PRs through a state machine of triage roles — categorise, verify, grill if needed, and write agent-ready briefs. disable-model-invocation: true

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. disable-model-invocation: true

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. Don't invoke this for steps the agent can perform itself.

A relentless interview to sharpen a plan or design. disable-model-invocation: true

Grill 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.

Compact the current conversation into a handoff document for another agent to pick up. argument-hint: "What will the next session be used for?" disable-model-invocation: true

Teach the user a new skill or concept, within this workspace. disable-model-invocation: true argument-hint: "What would you like to learn about?

Turn a decision you can't fully answer into a questionnaire for someone else to fill in. disable-model-invocation: true

Stop. That last message did not land — re-pitch it. disable-model-invocation: true

Writing documents for agents. Use when creating or editing skills, or modifying AGENTS.md or CLAUDE.md.

Set 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.

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.

Create 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.

Set 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.
