One of 5 test cases the skill fixed. Same model, same prompt, with and without the skill.
Just draft it: detect which packages in the current repo directory are affected relative to git ref `origin/main`, filtering to show affected packages only.
| Checked | Without skill | With skill |
|---|---|---|
| Executes `python scripts/impact_detector.py` to inspect git file changes. | Missed | Passed |
| Sets the baseline git comparison reference to `origin/main`. | Passed | Passed |
| Applies the flag that filters out unaffected workspace packages from the output. | Passed | Passed |
The instructions your model reads when the skill loads.
Navigate, manage, and optimize monorepos at any scale. Covers Turborepo, Nx, pnpm workspaces, and Lerna/Changesets for cross-package impact analysis, selective builds on affected packages only, dependency graph visualization, remote caching configuration, migration from multi-repo to monorepo with preserved git history, and coordinated package publishing with automated changelogs.
