Context Summarizer

Summarize long conversations to fit within token windows.

When to use

• Conversation history exceeds 50% of the available token window
• Starting a new context window after a long agent session
• Preparing context for handoff between agents
• Reducing token usage to improve response latency

Summarization strategy

1. Priority system: Keep these items at full fidelity:

   • User's current request
   • Active file paths and code changes
   • Unresolved errors or warnings
   • Current task status (from progress-tracker)

2. Compression rules:

   • Previous successful steps → one-line summary each
   • Debug output → discard (unless relevant to current issue)
   • Error traces → keep only the key error message (strip full backtrace)
   • Code diffs → keep only the summary line (file changed + +/- stats)

3. Output format:

## Context Summary
- **Task**: {current objective}
- **Files changed**: {list of files}
- **Progress**: {N/M steps completed}
- **Active issues**: {error descriptions}
- **History**: {2-3 sentence summary of what was done}
