Brave video response shape changed: {e}
Error message
Brave video response shape changed: {e} What it means
Raised inside the Brave video-search tool's execute when deserializing the Brave VideoSearch API response fails because the JSON shape no longer matches the structs the tool models (missing/renamed fields, changed nesting). It is an upstream-contract-drift signal — the faulty input is Brave's response payload, not the user's query — surfaced to the agent transcript as a tool error rather than a panic.

Solutions
- Compare the failing payload against current Brave VideoSearch API docs and update the response structs.
- Make the deserialization tolerant: default optional fields, ignore unknown fields, or parse defensively field by field.
- Add a pinned response fixture test so future Brave API changes fail in CI instead of in the field.
- Retry the search with a different tool (e.g. web search) to still serve the user's request.
