Adversarial second-pass review that tries to break code, designs, plans, or ADRs. Use when stakes are high and a normal review already ran.
Configure Claude Code agent teams (implicit team, SendMessage, TaskUpdate). Use when running parallel agents, coordinating with messaging, or setting up a lead/teammate architecture.
Gate outward-bound text (upstream issues, docs, PR bodies) through isolated haiku fresh-reader critique before publishing. Use when an artifact must survive a reader with zero project context.
Write and configure custom agent definitions in Claude Code agents/ directory. Use when creating an agent .md file, defining a specialized agent, or configuring agent tools.
Pre-dump-then-dispatch for tools holding an exclusive lock (Ghidra, migrations, single-writer caches). Use when fanning out parallel agents needing a non-concurrent resource.
Execution-grounded review: run tests first, trace each acceptance criterion to execution evidence. Use when verifying an implementation meets spec.
Copy, generalize, or merge a project's .claude/{agents,commands} into user-scoped configuration. Use when assimilating another project's Claude setup or generalizing an agent.
Audit Claude subagent configs for completeness, security, and best practices. Use when reviewing agents/ for missing frontmatter, overprivileged tools, or bad model choices.
