LevelCode v1.0.1

A reliability patch. A transient upstream hiccup now retries and recovers instead of killing your run, and when something does fail you get an honest, readable message rather than a wall of proxy HTML mislabeled "OpenAI".

Highlights

Runs survive a transient upstream blip

When the model gateway briefly can't reach a healthy backend it returns a 502 / 503 / 504 — a momentary hiccup that used to end the whole run. LevelCode now retries once, before anything has streamed, so the common case (the backend is fine a second later) just recovers and your turn carries on. You'll see a brief upstream busy — retrying… instead of a dead run.

It's deliberate about when it retries: only a 502, 503, or 504, and only before any output has appeared — so a retry can never duplicate text or double-charge. It does not retry a rate-limit (429), a 500, any other 4xx, or an aborted request, and a 401 still refreshes your session as before. Hitting Stop during the wait stays instant.

Honest error messages

A gateway failure used to land in the chat verbatim, like this:

OpenAI API 502: <html><head><title>502 Bad Gateway</title></head><body>…

Two things were wrong: it was labelled OpenAI even for an Anthropic model on your LevelCode Cloud plan, and it pasted the raw nginx error page into the transcript. The same failure now reads:

LevelCode Cloud API 502: Bad Gateway

The route is named correctly — LevelCode Cloud, OpenRouter, or whichever provider actually handled it — and the body is parsed for a real message. An HTML proxy page carries none, so it falls back to the plain status reason instead of being dumped in.

Under the hood

  • The repository's LICENSE is now recognised as MIT by GitHub. The MIT text is kept verbatim so the detector matches it, the Code-OSS provenance + trademark notice moved to a dedicated NOTICE file, and the in-app license link points at a branch that exists (HEAD) rather than a main that never did (it had been a 404).

Test coverage

  • 24 suites across the bundled extensions, all green on every release.
  • providers.test.js grew to 28 cases: the error sanitiser (a real nginx 502 page collapses to Bad Gateway, a JSON {error:{message}} is preserved, the label names the route — not the adapter) and the retry (recovers on a 502-then-200, gives up cleanly after one try, never retries a 4xx or an abort). The retry is also exercised end-to-end against a stubbed stream, so the whole router → adapter path is covered, not just the helper.
