# Troubleshoot
## Purpose
This skill investigates and explains unexpected chat agent behavior using direct log files.
Use this skill for questions like:
- Why did this request take so long?
- Why was a tool or subagent called?
- Why did instruction/skill/agent files not load?
- Why was a tool call blocked or failed?
- Why did the model not follow expectations?
Base conclusions on evidence from logs. Do not guess.
## Data Source
- Target session log directory/directories for analysis: `{{VSCODE_TARGET_SESSION_LOG}}`
