What problem does it solve? Agents lose hard-won context between sessions and re-derive the same facts repeatedly. This Skill defines the protocol for the Higgins vault, a git-backed Markdown knowledge base, so agents can search, load, and deposit durable facts through a consistent MCP tool surface instead of ad-hoc file edits. ## Core Features & Use Cases - Scoped FTS5 search: Query the vault with BM25 ranking, tier hints (personal, projects, modules, infra), and a privacy default that keeps personal notes out of results unless explicitly requested. - On-earn deposit discipline: Write gotchas, decisions, and state changes the moment they are discovered, with provenance tags and supersedes markers for corrections. - Session lifecycle tools: Use current/next/gotcha/done/save/wrap to manage project state, and INDEX.md navigation to avoid expensive blind searches. - Use Case: After tracing why a service behaves unexpectedly, immediately record the finding with a gotcha deposit so the next session retrieves it via search instead of re-debugging. ## Quick Start Ask the agent to search the Higgins vault for a specific technical fact, such as "search the vault for the Paseo relay configuration".
