Scoped hard reasoning - architecture trade-offs, cross-module debugging, security analysis, migration risk, performance investigation. Use whenever a single hard question needs deep analysis but not a conversation, even if nobody says "delegate". One question in, one decision-grade analysis out. Read-only; never…
Local code reviewer and the designated reviewer for Codex-authored diffs. Use before any merge whenever the diff was authored by Codex (Codex never reviews its own work), Codex is unavailable, its quota window is exhausted, or the code must not leave the machine. Reviews the branch diff against its spec for…
