Congratulations on your new Raycast extension! 🚀

We're currently experiencing a high volume of incoming requests. As a result, the initial review may take up to 15 business days.

Once the PR is approved and merged, the extension will be available on our Store.

Greptile Summary

Peepy adds a cross-platform Raycast command that keeps macOS and Windows systems awake using detached native helpers. The latest changes add Store metadata and repository-standard configuration while attempting to protect helper termination against PID reuse.

• Adds timed and indefinite keep-awake controls with live diagnostics.
• Persists helper state and process identity in Raycast's support directory.
• Adds extension metadata, changelog, manifest schema, and standard lint/format configuration.

Confidence Score: 4/5

The PR is not yet safe to merge because helper shutdown can still terminate an unrelated process when process identity data is unavailable.

The attempted PID-reuse protection explicitly accepts missing identity timestamps, and the accepted PID is subsequently terminated by stop, reset, and replacement-start paths.

Files Needing Attention: extensions/peepy/src/lib/caffeine.ts

Important Files Changed

Filename	Overview
extensions/peepy/src/lib/caffeine.ts	Implements cross-platform helper lifecycle and PID identity checks, but unavailable creation-time data still authorizes termination of a potentially unrelated process.
extensions/peepy/src/peepy.tsx	Provides the keep-awake controls, timed presets, status refresh, and diagnostics UI that invoke the helper lifecycle.
extensions/peepy/package.json	Defines a valid cross-platform view command with Store categories, schema metadata, and standard scripts.
extensions/peepy/CHANGELOG.md	Adds the requested Initial Release entry.
extensions/peepy/eslint.config.js	Uses defineConfig from eslint/config and composes the recommended TypeScript, Raycast, and Prettier presets.

### Issue 1
extensions/peepy/src/lib/caffeine.ts:148-156
**Missing Identity Still Authorizes Termination**

When the recorded creation timestamp is absent or the live identity lookup fails, `identityMatches` returns true, so disabling, resetting, or restarting Peepy can terminate an unrelated process that reused the helper PID, including its descendants on Windows.

```suggestion
function identityMatches(state: RunningCaffeineState, identity: ProcessIdentity | null) {
  if (!identity || identity.createdAtMs === null || state.helperCreatedAtMs === undefined) {
    return false;
  }

  return Math.abs(identity.createdAtMs - state.helperCreatedAtMs) <= PROCESS_IDENTITY_TOLERANCE_MS;
}
```
