Description

Edit

Before compacting conversation history, run a silent turn prompting the agent to save important context to memory.

Inspired by moltbot's memory flush system:

  • Triggers when session nears context limit (configurable threshold)
  • Runs a silent agent turn with prompt like:

'Session nearing compaction. Save any important context to memory. Reply NO_REPLY when done.'

  • Only provides remember tool (minimal toolset)
  • Tracks flush per compaction cycle (don't flush twice)
  • NO_REPLY response is discarded

Implementation: 1. Add flush hook to Programs/Compaction.hs 2. Configure soft threshold (e.g., 4000 tokens before hard limit) 3. Add config: compaction.memoryFlush.enabled, .softThresholdTokens, .prompt

Ava triage: pipeline auto-run reached status=done but the agent made NO git commits and reported blockers (missing files, path mismatches, or need clarification). This task is not actually in review — there's nothing to review. Resetting status to Open so it can be re-scoped.

ORPHAN COMMIT: coder agent produced commit e2eb0d84282f4aa3c25824fe89b749eef86811b7 on 2026-02-19 but it was never merged into live. Reachable only via branchless reflog. Pipeline scheduler bug — see separate task. To recover: git cherry-pick e2eb0d84282f4aa3c25824fe89b749eef86811b7 from omni/live (expect conflicts after 6+ weeks of drift). Otherwise re-implement from scratch.
