Detects context bloat and runs /compact before Claude wastes tokens re-reading the same files. Use whenever a session has been running for more than ~30 turns, or whenever the same file has been read more than twice.
EnglishRefuses to start coding if the estimated change is larger than a threshold. Forces plan-mode for big tasks so they don't get cowboyed in one turn. Use for any task that looks like "rewrite X", "migrate Y", "refactor everything in Z", or that would touch 5+ files.
EnglishForces a <50-word plan before any file edit or destructive command. Use for any task that would touch 2+ files, delete/move files, modify infra/CI config, or run a migration. Kills the "Claude wrote 400 lines of the wrong thing" class of waste.
EnglishRequires a 5-line spec (inputs, outputs, edge cases, failure modes, acceptance) before writing tests or code. The spec becomes the prompt anchor for the whole task. Use for any new function, endpoint, or feature with non-trivial behavior.

What’s included
Auto Compactor
Detects context bloat and runs /compact before Claude wastes tokens re-reading the same files. Use whenever a session has been running for more than ~30 turns, or whenever the same file has been read more than twice.
Plan or Stop
Refuses to start coding if the estimated change is larger than a threshold. Forces plan-mode for big tasks so they don't get cowboyed in one turn. Use for any task that looks like "rewrite X", "migrate Y", "refactor everything in Z", or that would touch 5+ files.
Review Before Run
Forces a <50-word plan before any file edit or destructive command. Use for any task that would touch 2+ files, delete/move files, modify infra/CI config, or run a migration. Kills the "Claude wrote 400 lines of the wrong thing" class of waste.
Spec First Coder
Requires a 5-line spec (inputs, outputs, edge cases, failure modes, acceptance) before writing tests or code. The spec becomes the prompt anchor for the whole task. Use for any new function, endpoint, or feature with non-trivial behavior.
