Dead code and dependency cleanup, repo-wide: unused deps, unreferenced exports, unreachable code, orphaned files — removed only with tool evidence, in reversible waves. Runs on green main. For diff-scoped cleanup use absolute-simplify. Triggers on "absolute prune", "remove dead code", "find unused deps/exports", "what can we delete", "clean up orphaned files".

Start your first response with the ✂️ emoji.
Cut dead growth from the repo: unused dependencies, unreferenced exports, unreachable code, orphaned files. Evidence-based — every removal is backed by a tool that proves nothing references it — applied in safe waves with tests green after each.
Runs the shared engine in references/health-engine.md — read it for the
DETECT → SCAN → TRIAGE → FIX → VERIFY → REPORT loop and the safety contract. This file
covers only what's specific to pruning.
prune vs simplify: simplify polishes your working git diff. prune sweeps the
whole committed repo for things that are dead repo-wide. Use simplify mid-change;
prune as standing cleanup on green main.
Dead dependencies — declared but never imported (and missing deps that are imported but undeclared):
| Ecosystem | Tool |
|---|---|
| JS/TS | depcheck or knip (knip also covers exports/files) |
| Python | deptry |
| Go | go mod tidy (diff), unused module detection |
Dead code — unreferenced exports, unreachable branches, orphaned files:
| Ecosystem | Tool |
|---|---|
| JS/TS | knip (exports/files), ts-prune, eslint no-unused-vars |
| Python | vulture, ruff unused rules |
| Go | deadcode ./..., staticcheck (U1000) |
Prefer tools already in the project. Treat results as candidates — verify each isn't reached via dynamic import, reflection, DI, public API, or a config string before removing.
| Wave | Removal | Default |
|---|---|---|
| 1 | unused devDeps, unreferenced local exports/functions | fix now — lowest risk |
| 2 | unused runtime deps, orphaned internal files | fix this pass after confirming no dynamic ref |
| 3 | anything reachable via public API, plugin system, dynamic require, reflection, or config | gated / usually defer — high false-positive risk |
Static tools miss dynamic references. Anything in wave 3, or anything a tool flags but you can't prove is dead, gets confirmed with the user or deferred — never auto-removed.
preferences.health.protectedPaths from config as never-delete globs — anything
matching is out of scope even if a tool flags it.exports map.prune removes dead things; it does not restructure live code.
Restructuring → simplify or work./absolute simplify — for restructuring/clarity of live code in your diff./absolute upgrade — pairs well: prune unused deps, then upgrade what remains./absolute debt — pruning often clears a batch of lint/unused-var warnings too.아직 리뷰가 없습니다. 사용해 본 소감을 남겨 주세요.

Vulnerability and security scan (defensive, your own repo): dependency CVEs plus risky code patterns (secrets, injection, weak authz), severity x reachability triaged and remediated without suppressing. Complements the built-in /security-review. Triggers on "absolute audit", "security audit", "are we vulnerable", "scan for CVEs", "check for secrets/injection", "harden this".

Lint and typecheck debt paydown: clear pre-existing repo-wide lint/type violations and suppressions (@ts-ignore, # type: ignore) one rule per wave, fixing causes not symptoms. Runs on green main. For diff-scoped quality use absolute-simplify. Triggers on "absolute debt", "fix our lint warnings", "clear the type errors", "get to strict mode", "burn down suppressions".

Flaky test fixes: detect nondeterministic tests empirically (repeat/shuffle/parallel runs), diagnose the root cause, fix it — never retry/skip/sleep — and verify across many randomized runs. Triggers on "absolute deflake", "fix flaky tests", "CI is flaky", "this test fails randomly/intermittently".

Diátaxis-driven documentation for AI coding agents: write, improve, or audit tutorials, how-tos, reference, explanation, and developer docs (README, CONTRIBUTING, ADRs). Detects the docs stack; gates on the outline before writing prose; verifies every claim against the code before it ships. Triggers on "absolute docs", "write docs", "write a tutorial", "write a README", "document this", "improve this doc", "audit our docs".

One-time setup for absolute: interview how you want it to behave (output style, autonomy, TDD strictness, spec dir, families) + detect the stack once, then write `.absolute.config.json` (project, committed) and `~/.absolute/config.json` (user defaults + per-project overrides). Every other absolute-* command reads it instead of re-detecting; non-blocking — commands proceed without it and soft-recommend it. Triggers on "absolute init", "set up absolute", "initialize absolute", "configure absolute", "first-time setup", "remember my conventions for this repo".

Use when the user wants to simplify, clean up, refactor, tidy, or refine code — their staged/unstaged git changes or a target file/path. Reduces complexity, flattens nesting, removes redundancy and dead code, scores each change by value (holding low-value churn), then runs tests to prove nothing broke. Invoke on: "simplify", "simplify this", "simplify my code/changes", "clean up", "clean this up", "clean up my changes", "refactor this", "make this cleaner", "tidy this up", "reduce complexity", "flatten this", "remove dead code", "make it more readable", "polish before commit", or "absolute simplify". Acts on your working diff; for repo-wide dead code use absolute-prune; for lint/type debt use absolute-debt.
