Skill Claude CodeCodex needs its repo
Implement comprehensive testing strategies using Jest, Vitest, and Testing Library for unit tests, integration tests, and end-to-end testing with mocking, fixtures, and test-driven development. Use when writing JavaScript/TypeScript tests, setting up test infrastructure, or implementing TDD/BDD workflows.
Skill Codex
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.
Skill Codex
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.
Skill Codex
Use when you need to resolve an in-progress git merge/rebase conflict.
Skill Claude CodeCodex
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.
Skill Codex
Test-driven development. Use when the user wants to build features or fix bugs test-first, mentions "red-green-refactor", or wants integration tests.
Skill Claude CodeCodex
Teach the user a new skill or concept, within this workspace.
Skill Claude CodeCodex
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.
Skill Claude CodeCodex
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.
Skill Claude CodeCodex
Move issues and external PRs through a state machine of triage roles — categorise, verify, grill if needed, and write agent-ready briefs.
Skill Claude CodeCodex
Master TypeScript's advanced type system including generics, conditional types, mapped types, template literals, and utility types for building type-safe applications. Use when implementing complex type logic, creating reusable type utilities, or ensuring compile-time type safety in TypeScript projects.
Skill Claude CodeCodex
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.
Skill Claude CodeCodex
A workflow for turning Codex and Claude Code session records into readable Markdown work logs. It can organize activity by project and date range, such as today, this week, or a custom period.
Skill Claude CodeCodex
Reference for writing and editing skills well — the vocabulary and principles that make a skill predictable.
Skill Codex
A required startup procedure for AI coding tasks. It checks project knowledge and applies relevant practices before other work begins.
