Agent
Read-only investigation engine: codebase exploration, auditing, research, and runtime evidence gathering for a failure. Cannot modify files. Use before planning, to answer a question that requires grounding findings in evidence (file:line, config value, schema fact), or to reproduce a failure and capture its runtime…
Agent
Implements all files listed in an approved plan. Writes production code, configuration, and updates test implementations. Use after test skeleton approval.
Agent
Designs implementation plans for coding tasks. Writes plan.md and capabilities.md to the project root. Use after exploration, before test writing.
Agent
Reviews an implementation diff in two passes (spec-compliance first, then code quality). Read-only. Returns structured findings. Replaces the separate spec/code-quality reviewers.
Agent
Writes test skeleton files with method signatures and assertions based on an approved plan. Use after plan approval, before implementation.
