What it installs

Skills (27)

  • verify

    Drive this checkout's skills the way a user does — load the working tree as the plugin in a headless Claude Code session inside a scratch repo, type the slash commands and answers, and capture what the skill did. Use to prove a skill or agent edit behaves before it is committed or pushed, or when as

  • brainstorm

    Explore a vague problem as very different Directions, side by side, and file the ones you keep as Issues.

  • code-review

    Review changes since a commit, branch, or tag against the coding standards and the Spec. Use when the user wants a branch, a PR, or work in progress reviewed.

  • doctor

    Moves documents into this project's canonical layout, closes local Issues the code already implements, brings every ADR to state the decision in force, trims oversized Coding standards to one short line per rule, and cleans repeats, dead paths, and contradictions out of Steering files.

  • domain-modeling

    Build and sharpen a project's domain model, its glossary and ADRs. A Library skill other skills read by path.

  • explain

    Explain anything as a written walkthrough, a diagram in the chat, an HTML page, or a narrated video, picking the format that fits.

  • grill-with-docs

    A relentless round-by-round interview to sharpen a plan or design, which also creates docs (ADRs and glossary) as we go.

  • grilling

    Grill the user relentlessly about a plan or design, round by round. A Library skill other skills read by path.

  • hillclimb

    Hillclimb one measured number — test-suite time, build time, memory, bundle size — keeping only the changes that measurably help. Use when the user wants something made faster, smaller, or cheaper, as far as it will go or past a target.

  • hunt-codebase-improvements

    Hunt your codebase for improvements along eight axes, such as state bugs, cruft, slow pages, and wasted CI time, then triage what the hunt finds into Issues.

  • implement

    Implement a spec by slicing it into steps, then a loop of implement, review, and verify, each in its own sub-agent. Use only when the user or a /goal names /implement.

  • learn-habits

    Rebuild a person's Grilling profile from the Habits in their past grilling sessions.

  • pr

    Pull request descriptions. Use when writing the description of a pull request or merge request.

  • prototype

    Build a throwaway prototype to answer a design question, then turn the answer into a Spec. Use when the user wants to sanity-check whether a state model or logic feels right, or explore what a UI should look like.

  • 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.

  • resolving-merge-conflicts

    Resolve git merge or rebase conflicts. Use when the user asks to merge or rebase and resolve the conflicts, or when a merge or rebase stops on a conflict.

  • retro

    Read a window of past sessions, apply high-priority changes this repository owns for lessons that repeat, file the structural ones as Issues, and summarise the rest.

  • setup

    Set up or update the repo's Tracker ref, where its Issues live; its Verify skill, which drives the app the way a user does; or its Models ref, the model and effort each plugin agent runs at.

  • simulate-first-users

    Send five simulated first-time users through your app in real browsers, then triage what tripped them up into Issues with screenshots.

  • technical-writing

    The house standard for every sentence a person reads. A Library skill other skills read by path.

  • to-spec

    Turn the current conversation into a Spec and write it onto its Issue in the repo's Tracker — no interview, just synthesis of what you've already discussed.

  • triage

    Sort incoming reports into Specs and parked Issues — one Issue per distinct problem.

  • validate-spec

    Validate an Issue, a Spec, a plan, or the current conversation against this repo's own template rules and the current codebase — fix stale references and contradictions in place, flag real decisions as open questions.

  • wayfinder

    Plan a change too big for one agent session as a shared map of decision tickets in the repo's Tracker, resolved one at a time until the way is clear and its Specs can be written.

  • what-did-i-get-done

    Summarise what you got done over a period, from your commits, pull requests, and Issues in this repo.

  • why

    Trace why code is the way it is, with every claim cited. Use for "why does X work this way", why a choice was made, a regression's origin, or before changing code that looks deliberate.

  • writing-for-agents

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

Subagents (9)

  • climber

    Writes one Attempt of a /hillclimb run — a single idea, left uncommitted for the driving session to measure. Dispatched explicitly by /hillclimb — it works to a contract decided before it starts, so it is not a general coding agent.

  • cold-reader

    Reads the Spec draft /to-spec has just written with nothing else and explains it back, naming each place it had to guess. Dispatched explicitly by /to-spec — it works to a contract decided before it starts, so it is not a general coding agent.

  • explorer

    Walks a codebase read-only and reports what it finds, without changing anything.

  • implementer

    Implements one Step of a Spec, or fixes what the last review or verify found, during an /implement run. Dispatched explicitly by /implement — it works to a contract decided before it starts, so it is not a general coding agent.

  • planner

    Slices a Spec into Step files at the start of an /implement run, commits them, and returns only the compact index. Dispatched explicitly by /implement — it works to a contract decided before it starts, so it is not a general coding agent.

  • researcher

    Investigates one question against primary sources and writes the findings to a Markdown file. Dispatched by /research to run in the background while the main session keeps working.

  • reviewer

    Reviews the changes since a fixed point along one axis — Standards or Spec — and reports findings without fixing them. Dispatched explicitly by /code-review — it works to a contract decided before it starts, so it is not a general coding agent.

  • validator

    Checks the Spec draft /to-spec has just written — corrects facts in the draft file and returns the report. Dispatched explicitly by /to-spec — it works to a contract decided before it starts, so it is not a general coding agent.

  • verifier

    Verifies one Iteration of an /implement run — checks the change against the Spec, runs the build and the whole test suite, runs the Spec's Hand checks, and measures its Stop rules. Dispatched explicitly by /implement — it works to a contract decided before it starts, so it is not a general coding ag
