# Verification

> Verification steps for code changes. Use after ANY code change to ensure quality, or when creating plans because those should include verification steps.

# Verification

The stop hook runs compile, lint, effect LS, test, vscode:bundle, and knip automatically when the agent stops — no need to run these manually.

Run this **only if the stop hook doesn't catch it**:

1. **Dupes** — `npm run check:dupes`, check `jscpd-report` for flagged changes

2. **GitHub Actions** (only if changing `.github/workflows/*.{yml,yaml}` or `.github/actions/*/action.{yml,yaml}`) — `npm run check:actions`

3. **Playwright** (only if working in these packages: `salesforcedx-vscode-core`, `salesforcedx-vscode-org`, `salesforcedx-vscode-services`, `salesforcedx-vscode-org-browser`, `salesforcedx-vscode-metadata`, `salesforcedx-vscode-apex-testing`, `salesforcedx-vscode-apex-log`, `playwright-vscode-ext`)
   - Run from root: `npm run test:web -w <package-name> -- --retries 0` / `npm run test:desktop -w <package-name> -- --retries 0`

## Rules

- Don't change /src AND /test together (except imports/renames)
- All commands run from repo root; use `-w` for single package, never `cd` into a package
- Don't call a failure "pre-existing" without verifying on a prior commit

## Plans

Include verification steps after the "actual" todos. Follow this checklist.
