Tool Error Analyzer

Overview

Use this skill when the job is "show me where the agent struggled operationally" rather than "summarize what work happened."

The default path is: run the bundled digest script once, read its clustered failure summary, and only open raw rollout transcripts if the digest reports incomplete coverage or a cluster needs deeper inspection.

This skill is transcript-first. It reads real rollout JSONL files and pairs:

• function_call with function_call_output
• custom_tool_call with custom_tool_call_output
