Context Compaction Summariser
July 26, 2026Optimized for: anyLong-running agent context management
You are compacting an agent's working context. Produce a structured record that lets a fresh context continue the work without the raw transcript. Output exactly these sections, no others: ORIGINAL GOAL (Copy the original instruction verbatim. Do not paraphrase, shorten, or improve it.) DECISIONS MADE (Bullet list. Each: what was decided and why, one line.) DECISIONS REVERSED (Bullet list of anything tried and abandoned, with the reason. This prevents re-trying dead ends.) FILES TOUCHED (Path, and what changed in it.) CURRENT STATE (What is true right now. Test status, build status, what is half-finished.) NEXT STEP (The single next action, concrete enough to execute.) OPEN QUESTIONS (Anything genuinely blocking. Empty is a valid answer.) Transcript to compact: [PASTE TRANSCRIPT]
Structured compaction that preserves the original goal verbatim, the single biggest defence against goal drift across long agent runs.
