Execute a multi-phase implementation plan by delegating phases to specialized sub-agents with fresh context windows. Use when user invokes run-plan with a plan file path or GitHub issue reference. Required argument: path to local plan file, GitHub issue number (e.g. `#456`), or full issue URL.
Interview the user relentlessly about a plan or design until reaching shared understanding, resolving each branch of the decision tree and the sub-decisions it unlocks. Use when user wants to stress-test a plan, get grilled on their design, or mentions "grill me", "devil's advocate", "challenge my assumptions", "poke holes in my plan", "what am I missing". Pass `--light` for a faster pass with no counter-challenges.
Grilling session that challenges your plan against the existing domain model, sharpens terminology, and updates documentation (CONTEXT.md, ADRs) inline as decisions crystallise. Use when user wants to stress-test a plan against their project's language and documented decisions. Pass `--light` for a faster pass with no counter-challenges.
Condense or split a repo's agent steering docs (AGENTS.md, CLAUDE.md, docs/agents/*) without losing load-bearing rules; surfaces contradictions between rules and produces a human-reviewed Removal Ledger before any deletion. Use to clean up, tighten, split, or de-conflict bloated or stale agent docs.
Turn a PRD into a multi-phase implementation plan using tracer-bullet vertical slices, saved as a local Markdown file and optionally published as a GitHub sub-issue. Use when user wants to break down a PRD, create an implementation plan, plan phases from a PRD, or mentions "tracer bullets". Accepts an optional GitHub issue reference (e.g. `#123` or a full issue URL) to link the plan as a sub-issue of that PRD-epic.
Create a PRD through user interview, codebase exploration, and module design, saved as a local Markdown file and optionally published as a GitHub issue with the `epic` label. Use when user wants to write a PRD, create a product requirements document, or plan a new feature. Pass `--no-github` to skip the publish prompt.
Generate a commit message from staged changes and commit. Accepts an optional ticket identifier argument.
Test-driven development with red-green-refactor loop. Use when user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants integration tests, or asks for test-first development.
