Behaviors Libra is checking
Board tool result payloads are schema-checked before rendering, so malformed or changed results render no board badge instead of crashing the transcript, while valid successful create_board results still show the clickable board badge.Not checked
prod
The board tool only uses a request-context runId when it is a string, treating missing or incorrectly typed values as undefined instead of passing invalid data downstream.Not checked
prod
Libra found 4 production surfaces on prod but could not judge any of them yet. 4 surfaces had no requests at all. Libra checks hourly for 3 days after each deploy.
Follow-up to #2896, which merged while this last fix was still in review.
Greptile flagged two as casts that PR added, both against CLAUDE.md's NEVER cast rule and both at exactly the boundary the rule exists for.
message.result as BoardCreateResult in the board result badge. A tool result off the wire is genuinely untyped , the assertion was the compiler agreeing with a guess the server is free to invalidate, which is the shape of the PipelineWidget crash CLAUDE.md cites. Parsed with zod instead, and .catch({}) rather than a throw: a badge that cannot read its own result should render nothing, not take the transcript down through the error boundary.
requestContext.get('runId') as string | undefined in boardTool, narrowed with a typeof check. The older casts on that same object are left alone , they predate this work.
No behaviour change: every access was already optional-chained, so a malformed payload rendered a disabled badge before and still does. The difference is that it is now checked at runtime rather than asserted away.
