| description | Validate implemented deslop-js detectors before PR or merge. Use after focused tests pass to review correctness, inspect false positives, update docs/changesets, write PR descriptions, and triage review comments. |
Rule Validate
Use this as stage 3 of the deslop-js detector pipeline.
Pipeline:
rule-research defines the finding contract.rule-writing turns the contract into fixtures, tests, implementation, and public result types.rule-validate verifies signal, noise, compatibility, docs, and release notes.
Validation is not just running tests. It checks whether the detector still matches the finding contract on fixture and project-shaped code.
Interactive Coaching
Before broad or expensive validation, tell the user what will run and what evidence it will produce.
Pause for the user only when:
- A review comment is ambiguous and could broaden v1 scope.
- A false-positive fix would change the finding contract.
- A check fails for unrelated repo state and the next step is not obvious.
Otherwise, fix real findings and add regression fixtures or assertions.
Local Validation
Build before tests after source edits.
Run the tightest useful checks first:
nr build from the repo root after source changes.- Focused
nr test or nr typecheck from packages/deslop-js/ while iterating.
- Root
nr test, nr typecheck, nr lint, and nr format when risk or user request justifies them.
Record every command as passed, failed, or not run. If a broad command fails because of unrelated repo state, record the failure location and the focused command that passed.
Implementation Review
Review the diff like a detector reviewer. Lead with bugs:
- False positives for valid or intentional code.
- False negatives for claimed behavior.
- Incorrect reachability, entrypoint, or public API handling.
- Import/export, re-export, namespace, default, side-effect, or type-only mistakes.
- Workspace, package.json script, dependency, peer dependency, override, or bin resolution mistakes.
- Path alias, extension, generated output, config file, declaration file, or test fixture mistakes.
- Semantic analysis that runs without
semantic.enabled or fails to degrade through analysisErrors.
- Confidence tiers or diagnostic reasons that overclaim.
- Missing fixture coverage for valid and invalid edge cases.
- Public result types, README docs, or changesets missing for user-facing behavior.
Fix every real implementation bug with a targeted regression fixture or assertion.
PR Description
Write PR copy after validation, not before. Use this structure:
## Why
Catches <specific dead-code/dependency/DRY issue>.
<Project behavior reason in 1-3 sentences.>
Before:
```ts
<bad or noisy example>
```
After:
```ts
<clean or intentionally quiet example>
```
## What changed
- Added or updated `<detector/result field>`.
- Detects <main detection surface>.
- Reports <exact condition and confidence>.
- Allows <important valid patterns>.
- Adds fixtures/tests for <edge cases>.
## Validation
| Check | Result |
| --------------------- | ------------------------------ |
| Focused tests | `<command/result>` |
| Typecheck | `<command/result>` |
| Lint/format | `<command/result or Not run>` |
| Fixture review | `<summary>` |
| False positives found | `<count after review>` |
## Test plan
- `<focused test command>`
- `<typecheck command>`
- `<lint/format command or Not run>`
Review Comment Triage
Classify each bot or human review comment:
- Fix now: real false positive, false negative for claimed behavior, graph/AST mistake, package resolution bug, semantic fallback bug, or public API mismatch.
- Usually fix: duplicated helper, misleading name, unnecessary abstraction, unclear confidence, or confusing reason text.
- Document or defer: false-negative coverage outside v1, expensive dynamic behavior, framework-specific conventions, or cross-package semantic modeling.
- Reject: broadens the detector beyond its result contract, increases false positives, or conflicts with repo conventions.
Resolve review threads only after the fix or explanation has landed.
Validation Output
Return:
Validation summary:
- <commands and results>
- <implementation review findings>
- <false positives found and fixed>
- <regression fixtures/tests added>
PR-ready notes:
- <Why/What/Test plan highlights>
Residual risk:
- <known v1 non-goals or unchecked areas>
