What problem does it solve? Pi agent session logs are multi-megabyte JSONL files, making it painful to find which sessions called a specific tool, which calls failed, and what arguments and results were involved. This Skill locates those sessions and extracts compact paired call/result records so diagnosis never requires reading the raw log. ## Core Features & Use Cases - Cross-session search: Find all sessions calling a given tool, filterable by argument substring (e.g. 'glab api' inside bash commands) and errors-only, with per-session match/error stats and sample error texts. - Paired calls dump: For one chosen session, dump toolCall-args plus toolResult-text records linked by call id, with configurable clipping of args and results. - Use Case: When subagent workflowScript calls keep failing, search with errors-only to triage affected sessions, pick the fullest finished one, and hand the calls dump to the tool-call-diagnose skill for root-cause analysis. ## Quick Start Find all my pi sessions where bash commands containing 'glab api' failed, then dump the paired call and result records for the most recent finished session.
