skills

Validate and triage pull-request review findings before addressing selected items.

Review changes since a fixed point (commit, branch, tag, or merge-base) along two axes - Standards (does the code follow this repository's documented coding standards?) and Spec (does the code match what the originating issue or PRD asked for?). Runs both reviews in parallel subagents 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.

Create git commits using Conventional Commits. Use when the user asks to commit code, prepare a commit, write a commit message, or standardize commit history with conventional commit types, scopes, breaking-change markers, and safe git workflow checks.

Publish the current branch as a review-ready pull or merge request.

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.

Opinionated guide for building production TypeScript applications with Effect v4. Use when implementing Effect workflows, services, layers, schemas, configuration, schedules, caches, streams, HTTP clients, Effect Atom or API-backed frontend state, or tests.

A relentless interview to sharpen a plan or design.

Grill the user relentlessly to sharpen a plan or design while maintaining ADRs and domain glossary documentation. Use when the user asks to "grill with docs" or wants decisions documented during a design interview.

Implement a piece of work based on a spec or set of tickets.

Scan a codebase for deepening opportunities, present them as a visual HTML report, then grill through whichever one you pick.

Investigate what a dependency upgrade would take before implementation by tracing upstream primary-source changes to repository usage.

Build a disposable 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.

Configure this repo for the engineering skills — set up its issue tracker, triage and Wayfinder label vocabulary, and domain doc layout. Run once before first use of the other engineering skills.

Fetch dependency source code so agents can inspect real implementations, tests, and version-specific behavior. Use when docs or types are insufficient, when debugging library internals, or when tasks require source-backed evidence. Triggers include "fetch source for", "read the source of", "how does X work internally", "get the implementation of", and "opensrc path".

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

Teach the user a new skill or concept, within this workspace.

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.

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.

Move issues and external pull requests through triage roles — categorise, verify, grill if needed, and write agent-ready briefs.

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.
