Individual skill
simplify-code
Use when correct working code is unnecessarily hard to read, change or verify and needs behaviour-preserving simplification in a bounded scope. Characterizes the observable contract, removes accidental complexity one concept at a time and proves equivalence. NOT fixing a failure (`debug`), NOT read-only diff judgment (`review`/`code-review`).

# simplify-code — fewer moving parts, same contract
Use this when the code already works and the desired change is easier reasoning, not new behaviour. The output is a smaller or clearer implementation plus proof that callers cannot tell the difference.
Default scope is the files or symbols the user named, or the recently changed slice. Expanding into adjacent cleanup requires a concrete dependency and must be stated. Never “clean the whole repository” as a side effect.
## The equivalence loop

BOUND → CHARACTERIZE → BASELINE → REDUCE → VERIFY → EXPLAIN
```
### 1. BOUND the work
