coding-tool

Single entry point for all implementation work. Triages tasks, manages beads issues, delegates to implementer skill, runs reviewers, creates PRs.

Pure development workflow with test-first development and coverage review. Used by coordinator as a subagent. Commits to its own worktree branch, but never pushes, manages beads issues, or opens PRs.

Review PR diff for bugs, error handling gaps, security issues, and API contract mismatches. Spawned by coordinator before PR creation.

Review PR test quality — meaningful coverage, edge cases, integration tests, and test accuracy. Spawned by coordinator before PR creation.

Day-2 training tutor for the agent-friendly-project exercise. Answers student questions about the process, the exercise, the workflow, the concepts from the training, or anything about this repo. Invoked via /tutorial.

Writing, running, and debugging Playwright E2E tests in coding-tool.

Process open PRs — merge when CI passes, handle rebases, file issues for failures. Run in a dedicated window.

Collaboratively plan epics by exploring the codebase, discussing tradeoffs, filing issues, and running plan review. Invoked via /plan.

Resolves rebase conflicts by gathering full context from beads issues, git diffs, and surrounding code. Invoked by coordinator and merge-queue after a fast-path rebase fails.

Review filed implementation plans for architectural issues, duplication risks, and completeness. Spawned by planner as a subagent.
