Demolish bloated code and re-derive it clean, cutting every surface the rebuilt contract does not name. Use for a repo-wide bloat sweep, when patching a subsystem has stopped paying, or when the user says "this whole module is bloated", "rewrite this properly", or "break it and rebuild".
Use when the user says "deslop", "remove debug code", "find placeholders or stub code", or "remove dead code".
Dispatch compress operations. Use when the user says "tidy" or names a file, diff, memory, workspace, git stack, or doc to tidy.
Reduce internal duplication, dead code, and ceremony. Use when you spot dead fields, redundant wrappers, or speculative abstractions in code you are already editing.
Use when modernizing APIs, removing compat shims, killing feature flags, or rewriting a subsystem cleanly.
Use when the user says "simplify this diff", or asks for a compression pass over a change-set.
Design-by-Contract (DbC). Use when crossing public API boundaries, guarding complex state invariants, or hardening untrusted inputs and integration seams.
Drive decomposable work as a deterministic multi-subagent workflow: phased fan-out under per-task contracts with adversarial verification. Use for audits, migrations, broad research or review sweeps, work needing independent cross-checks before committing, or scale one context cannot hold.
