tracelint reads the agent trace, not the alibi

A deterministic linter for tool-calling agent traces that flags structurally provable failures and can fail CI on them.

Landing page captured for the 2026-09-04 issue.

Field notes

The tool normalizes spans from systems such as Langfuse, Phoenix, LangSmith, OpenAI, and OpenTelemetry before applying deterministic structural checks. Its worked example records an HTTP 500 from get_order, reuses the failed order value in refund_order, and invokes that side-effecting operation twice. The page says findings can be emitted as JSON or SARIF and used to fail CI, while emphasizing that the checks do not call a model or judge the final prose.
