hard-cut
Remove a feature completely with no backward compatibility; delete surfaces, callers, tests, docs, fallbacks, stubs, and dead exports.
What this skill does
# Hard Cut
Use this when a feature should die, not linger.
## Rules
- Delete the surface. Do not deprecate it.
- Do not leave `throw new Error("Not implemented")`, placeholder notices,
"feature removed" banners, or TODOs about bringing it back unless the user
explicitly asks.
- Do not keep compatibility aliases, deprecated shims, fallback parsing,
migration bridges, or dead exports.
- Delete tests for deleted behavior. Keep tests only for the behavior that
still exists.
- Delete comments that describe deleted code or mourn the old feature.
- If removal exposes adjacent dead code, keep cutting until the graph is clean.
## Sweep
1. Find the real surface area:
- exports
- commands and flags
- routes
- UI entrypoints
- feature flags
- docs and examples
2. Trace references with `rg`.
3. Delete the implementation and the glue:
- call sites
- types
- state
- tests
- docs
- comments
4. Grep again for the removed name and obvious aliases.
5. Run the narrowest honest verification for the surviving product.
## Smells
- deprecated notices
- not-implemented throws
- stub handlers
- dead enum or union members
- permanently-false feature-flag branches
- unused env vars and config
- tests that only prove the deleted feature used to exist
## Bias
If the choice is between deleting more code and leaving a zombie surface, delete
more code.
