fix: handle API timeouts in worker

Reviewed

🏹 Robin

1 High · 1 Medium · 2 Suggestions

Summary

Focused change. Main risk: timeout errors are not handled clearly.

@@ src/worker.ts +12 -3

const worker = createWorker({)

  fetch: async (url) => {

-     return fetch(url)

+     await fetchWithTimeout(url, 5000)

  },

});

Robin · inline

Consider surfacing timeout errors with request context for easier debugging.

Findings not posted inline

src/config.ts:8 — Retries exist but timeout failures lack context.

  3. 3. Comment /robin for re-review

Three steps.
Reviews on autopilot.

I

Add three secrets

LLM_API_KEY, LLM_BASE_URL, and LLM_MODEL in your repo settings. Free OpenRouter setup takes two minutes.

II

Add the workflow

Run the one-line installer or copy .github/workflows/robin.yml. Pin @main or a release tag like @v1.

III

Open a pull request

Robin reviews within minutes. Push more commits without burning API calls. Re-run with /robin when you want.

One command.
Then add secrets.

The installer creates .github/workflows/robin.yml without overwriting an existing file. Finish by adding the three GitHub secrets and pushing. Read the script first →
