What problem does it solve? Valuable patterns from your Claude Code sessions—user corrections, error resolutions, repeated workflows—are lost when sessions end. This Skill observes tool usage deterministically through PreToolUse/PostToolUse hooks, distills recurring behaviors into atomic confidence-scored "instincts", and clusters them into reusable skills, commands, and agents, with project-scoped storage preventing cross-project contamination. ## Core Features & Use Cases - Hook-Based Observation: Captures 100% of tool calls via PreToolUse/PostToolUse hooks into project-scoped observations.jsonl files, with secret scrubbing and automated-session filtering. - Instinct Management CLI: Provides status, import, export, evolve, promote, projects, and prune commands for managing confidence-weighted instincts across project and global scopes. - Background Observer Agent: A Haiku-based observer loop analyzes accumulated observations on an interval or SIGUSR1 signal, guarded by active-hours, cooldown, and idle-detection gates. - Use Case: After repeatedly correcting Claude to prefer functional React components, the system creates a project-scoped instinct with rising confidence; when the same pattern appears in multiple projects at high confidence, it is promoted to a global instinct and evolved into a reusable skill. ## Quick Start Enable the observation hooks in your Claude Code settings and ask the assistant to run the instinct-status command to review learned patterns for the current project.
