Debug: Session Diagnostics

Help the user diagnose an issue they're encountering in their current Amplifier session.

Issue Description

$ARGUMENTS

If no issue was described, read the session logs and summarize any errors, warnings, or notable issues.

Instructions

1. Delegate to the session-analyst agent to investigate the current session. The session-analyst has specialized knowledge for safely analyzing large event logs (events.jsonl files can contain lines with 100k+ tokens that will crash other tools). Use the delegate tool to dispatch it with the issue description and any relevant context.

2. Check session configuration. Review the current session's configuration for common issues:

   • Bundle composition problems (missing modules, failed loads)
   • Provider configuration (missing API keys, wrong endpoints)
   • Tool availability (tools expected but not mounted)
   • Hook failures (hooks that errored during lifecycle events)

   Session and project settings are typically at:

   • Project: .amplifier/settings.yaml
   • User: ~/.amplifier/settings.yaml
   • Keys: ~/.amplifier/keys.env

3. Check for common patterns:

   • Tool calls returning errors repeatedly
   • Provider rejections (rate limits, auth failures, model not found)
   • Module mount failures at startup
   • Context overflow or compaction issues

4. Explain what you found in plain language. Avoid jargon. Tell the user:

   • What went wrong
   • Why it likely happened
   • Concrete steps to fix it

5. If the issue can't be diagnosed from logs alone, suggest the user:
