harness

AI project initializer.

Init

Initialize the current project:

npx @sha3/harness@latest init

Run the same command again to re-initialize an existing project. It refreshes the harness-managed files and scripts.

Managed agent files and MCP config are written under .claude/.

Init also runs Biome with --write after refreshing the config so existing supported files are reformatted immediately. It applies unsafe fixes aggressively, except fixes that remove console output or rewrite logical chains to optional chaining.

Preview changes without writing files:

npx @sha3/harness@latest init --dry-run

Scripts

The initializer recreates every package.json script prefixed with harness::

{
  "harness:init": "npx @sha3/harness@latest init",
  "harness:open-chrome-canary": "node scripts/open-chrome-canary.mjs",
  "harness:check": "biome check --config-path=biome/biome.json .",
  "harness:publish": "node scripts/publish.mjs"
}
