Your agent knows your preferences. It just never uses them

Your agent knows your preferences. It just never uses them

Short summary

Agent memory systems fail silently when preferences are stored correctly but never retrieved at the moment they matter — similarity search can't connect 'fix the login bug' with 'use conventional commit style.' The fix is action-triggered retrieval: tag rules with the action they govern (trigger:git-commit) and fetch them deterministically right before that action runs. A Claude Code hook injects matching rules into context before commits and PRs, with hard failure-to-silence guarantees so memory never breaks your workflow.

  • Agent preferences are rules about actions, not facts about topics, so similarity search misses them at the critical moment
  • Action-triggered retrieval tags rules with the action they govern and fetches them deterministically before that action runs
  • Claude Code hooks inject procedural rules before git commits and PRs, failing silently to avoid breaking workflows
