What's the API base URL? Check the docs.
The current API base URL is `https://api.example.com/v2` (from `docs/api-v2.md`). Note: the older `docs/api.md` lists `https://api.example.com/v1`.
Actually docs/api.md is outdated — docs/api-v2.md is the current one. What's the base URL?
The current base URL is `https://api.example.com/v2`, from `docs/api-v2.md`.
What's the API base URL? Check the docs.
The docs list two: - `docs/api.md`: `https://api.example.com/v1` - `docs/api-v2.md`: `https://api.example.com/v2` — marked "(current)" So the current API base URL is **`https://api.example.com/v2`**.
Actually docs/api.md is outdated — docs/api-v2.md is the current one. What's the base URL?
`https://api.example.com/v2` — that's the one from `docs/api-v2.md`.
The harness runs on every turn. Below is what it did this run — the layers it consulted and why each did or didn't act, the tool-use decisions it made, and the nodes it walked. Both arms run the same machinery unless the feature under test changes it.

|---|---|---|
