Minimizes test count while preserving coverage. Detects byte-identical pairs, parametrize-inflation, language-guarantee tests, AST-shape tests, stale migration nets. Approval gate before any change.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# NW-OPTIMIZE-TESTS: Test Suite Optimization
**Wave**: CROSS_WAVE
**Agent**: Trim (nw-test-optimizer)
**Reviewer**: Trim Review (nw-test-optimizer-reviewer)
## Overview
Dispatches Trim to inventory a test scope, detect duplication and anti-patterns, propose a consolidation plan, and apply it after explicit approval. Coverage is preserved; production code is never modified. Use after a feature lands, when a suite feels slow or noisy, on weekly audit, or whenever overtesting is suspected.
## Context Files Required
- The scope path (passed as argument or auto-detected)
- `~/.claude/skills/nw-test-optimization/SKILL.md` — methodology (loaded by agent)
## Timing Baseline
Trim compares against the wall-clock figures recorded in the execution-log.json.
## Agent Invocation
@nw-test-optimizer
Execute test optimization for `{scope}`.
**Configuration:**
- scope: <path | feature-id | empty for full unit suite>
- approval_required: true # always; gate is non-negotiable
- mutation_validation: false # set true for critical scopes (financial, safety, infra)
- reviewer_chain: false # set true to dispatch nw-test-optimizer-reviewer after apply
## Approval Gate

How to install
mdr add nwave-ai/nwave/nw-optimize-tests@sha256:2863cbea25ee927fThe line at the top of this page pins the label git:20260611.3860ed5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
