• code-review

  Review the changes since a fixed point (commit, branch, tag, or merge-base) along three axes: Standards (does the code follow this repo's documented coding standards?), Spec (does the code match what the originating issue/spec asked for?), and Adversarial (how does the change fail in production?). Runs each axis in a sub-agent and in the other model family, and reports the axes side by side with…

• codebase-design

  Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, deepen a chosen module, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module vocabulary.

• dependency-vetting

  Verify a package or tool is authentic before installing, adding, upgrading, or recommending it. Use whenever a task would add a dependency to a project, suggest a CLI tool, or pull a package from npm, PyPI, crates.io, Go modules, RubyGems, Homebrew, or any other registry. Also use when a registry page, install command, or installed artifact looks inconsistent with the project that supposedly publ…

• domain-modeling

  Build and sharpen a project's domain model. Use when discussing codebase terminology, resolving a vague or overloaded word, stress-testing how domain concepts relate, writing or editing a GLOSSARY.md, or recording or editing an ADR.

• grilling

  Grill the user relentlessly about a plan, decision, or idea. Use when the user wants to stress-test their thinking, says "grill me", or asks to poke holes in, challenge, or be interviewed about a plan or design, even without the word "grill".

  skills/improve-file-structure/SKILL.md on GitHub (opens in a new tab)

• improve-tests

  Cut a test suite to the tests that catch real bugs and its run time to the minimum: measure first, delete or demote low-value tests, fix slow setup, and prove every cut keeps the checks that matter.

• jury

  Put a question or decision to a jury of 3 or 5 subagents: blind independent votes, one anonymized review round, and one committed verdict with the vote, the dissent, and the first action.

• pr

  skills/pr/SKILL.md on GitHub (opens in a new tab)

• 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.

  skills/prototype/SKILL.md on GitHub (opens in a new tab)

• qa

  QA a change in the running program, the way its user meets it: drive a CLI or terminal UI through tmux, a web app through a browser, and check every requested behavior against what you observe. Use after implementing a change and before code review, or when the user asks for a QA pass, a smoke test, or a click-through of a change, or asks whether it actually works.

• refactor

  Refactor code at method, file, or project scope. Assesses first and stops when the code is already clean, routes architecture problems elsewhere, and gates edits on test coverage. Language-agnostic.

• 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.

  skills/research/SKILL.md on GitHub (opens in a new tab)

• resolving-merge-conflicts

  Resolves an in-progress git merge or rebase conflict by tracing why each side changed, reconciling every conflicted hunk, running the project's checks, and finishing the merge or rebase. Use when a merge, rebase, or pull stops on conflicts, when files contain conflict markers, or when the user asks to fix or resolve merge conflicts.
