 - The plugin checks launchers in this order: PATH -> local npm bin -> global npm -> python.
 - "local npm bin" means `plugins/openclaw/node_modules/.bin/headroom` relative to the source checkout.
 - Using `--link dist` (or `--link .` from `dist/`) still keeps runtime code adjacent to the checkout, and launcher detection falls back to PATH/global/python if a local npm bin is not present under the installed root.
+- `plugins/openclaw` also carries a no-op hook shim so OpenClaw's hook-pack fallback treats the path as valid instead of emitting a misleading `package.json missing openclaw.hooks` warning.
 - If you install from a `.tgz`, local npm bin may not exist in the installed extension and detection will fall back to PATH/global/python.

+# Headroom Link Shim
+
+This hook intentionally does nothing.
+
+OpenClaw currently falls back to validating local plugin paths as hook packs when a
+plugin install cannot proceed, such as when the plugin is already installed.
+Including this no-op hook keeps `--link` installs from reporting a misleading
+`package.json missing openclaw.hooks` error for valid Headroom plugin paths.
