Priority: P1 (OPTIMIZATION)
Manage the Attention Budget. Treat context as a scarce resource.
1. Observation Masking (Noise Reduction)
Problem: Large tool outputs (logs, JSON lists) flood context and degrade reasoning. Solution: Replace raw output with semantic summaries after consumption.
- Identify: outputs > 50 lines or > 1kb.
- Extract: Read critical data points immediately.
- Mask: Rewrite history to replace raw data with
[Reference: <summary_of_findings>]. - See:
references/masking.mdfor patterns.
2. Context Compaction (State Preservation)
Problem: Long conversations drift from original intent. Solution: Recursive summarization that preserves State over Dialogue.
- Trigger: Every 10 turns or 8k tokens.
- Compact:
- Keep: User Goal, Active Task, Current Errors, Key Decisions.
- Drop: Chat chit-chat, intermediate tool calls, corrected assumptions.
- Format: Update
System PromptorMemory Filewith compacted state. - See:
references/compaction.mdfor algorithms.
3. KV-Cache Awareness (Latency)
Goal: Maximize pre-fill cache hits.
- Static Prefix: strict ordering: System -> Tools -> RAG -> User.
- Append-Only: Avoid inserting into the middle of history if possible.
