Agent Skills: collapse-pass

Run a continuous collapse-and-simplify pass that surgically removes indirection failing to earn its boundary. Use when the user says 'collapse pass', 'simplify pass', 'reduce indirection', 'shrink the surface', 'find what to delete', when asking to audit a package for dead abstractions, when reviewing a pull request, branch, or recent merged change for simplification (isolated in a worktree), or when the goal is a sequence of small refactor commits that delete more than they add. Pairs with code-audit (smell catalog), refactoring (per-change mechanics), one-sentence-test (cohesion gate), cohesive-clean-breaks (deep redesigns), approachability-audit (first-read sanity), and post-implementation-review (second-read after each commit).
