  "title": "Auto-inject vault context file at AI agent session start to reduce token waste",
  "summary": "Introduces a SessionStart hook that automatically loads the vault's _CLAUDE.md configuration into the AI assistant's context at launch, removing the need to re-read the file on each subsequent command.",
  "contribution": "Automated pre-session context loading via a SessionStart hook to eliminate redundant configuration file parsing.",
  "impact": "AI agent users working inside a vaulted knowledge base will cut API costs and speed up multi-turn tasks by preventing the assistant from repeatedly reading its own configuration file. The new hook loads the setup document once at launch instead of on every command, which stabilizes context windows and reduces unnecessary token burn. Teams should watch for failures when vault paths change or permissions shift, and verify that the hook remains isolated from external integrations that do not share the same directory structure.",
