Respond to a Codex bulk-read hook block by replacing an oversized full-file read with targeted inspection or bounded subagent delegation.

Investigate failures whose cause is unclear or whose fixes keep failing.

Design or review public or shared API, CLI, and data contracts when callers depend on stable inputs, outputs, errors, or compatibility.

Review a bounded codebase area for architectural friction and propose owner-scoped interface improvements when explicitly requested.

Cache and refresh remote git repositories under the ~/.cache/checkouts host/org/repo layout when local source inspection or repeated reference work benefits…

Reduce unresolved feature or workflow scope by questioning requirements, deleting unnecessary work, and deciding whether automation is justified.

Find the mistakes agents keep repeating in this repo and make each one impossible.

Vet a perf measurement (limiter, tuning, limits, errors, repeatability, relevance, and whether the work happened) before you report or act on it.

Design an auditable playbook when no narrower one fits: a large migration, an ambitious multi-part change, or work a human reviews after stepping away.

Spawn N parallel candidates at the same task, pick a base, graft the strongest parts of the losers into it.

Periodic pass that keeps a project's verification skill and feature map honest: parallel source readers per feature, one live session driving every feature…

Sketch types, signatures, and module structure before code, then stay in the loop while implementation fills in.
