Biome anti-slop

Vendor the bundled rules into the current repository and integrate them with its existing Biome setup. Preserve unrelated work and adapt to the repository's package manager and configuration.

Install

1. Inspect the repository before changing it:

   • Read applicable agent instructions and check git status.
   • Detect the package manager from packageManager and lockfiles.
   • Find biome.json or biome.jsonc files and existing anti-slop rules.
   • If multiple independent Biome roots exist, ask which one to configure.

2. Require @biomejs/biome version >=2.5.9 <3. Preserve an existing dependency in that range. If Biome is absent from a package manifest, install the latest compatible 2.x release using @biomejs/biome@^2.5.9 as a development dependency with the repository's package manager. If the repository uses a version outside that range, stop and ask before changing it.

3. From the target repository, copy the bundled rules:

   node <skill-directory>/scripts/install.js
   

   The default destination is tools/biome/anti-slop. Pass another relative destination as the first argument when the repository has an established tooling layout. The installer refuses to replace an existing destination; use --force only after reviewing the existing files and the replacement diff.

4. Register the installed rules. Do not type the rule names from memory or from this file. The installer prints two lists, read from the // scope: line each rule declares, so they cannot go stale as rules are added, merged, or removed:

   • the global list goes in the top-level plugins array;
   • the tests list goes in a plugins array on an overrides entry matching **/*.test.ts and **/*.test.tsx, because those patterns are legitimate in product code and only wrong in a test.

   Add them without removing existing plugins.
