{"name":"agent-trace-brief","description":"Turns a raw agent execution trace into a readable agent trace summary: an ordered step-by-step account of what the agent did, where it broke, and why. Built for tool call debugging when a run fails silently or an agent loops without explanation: send the trace array or log and get back failure points plus a root-cause hypothesis grounded only in what the trace actually shows, with anything it can't determine labeled unknown instead of guessed. Useful for agent run analysis after an incident, before a retry, or as part of a CI check on agent behavior. Use it as an agent debugging API, a trace root cause tool, or a post-mortem generator for agent pipelines.","price":"$0.02","method":"POST","input_schema":{"properties":{"trace":{"type":["array","string"],"description":"The agent execution trace: either a JSON array of step/tool-call objects, or a plain-text log.
