{"slug":"nczz-pi-knowledge","name":"Pi Knowledge","description":"A local-first RAG knowledge base for Pi agents that indexes code, docs, and notes for persistent, searchable project memory across sessions.","long_description":"# pi-knowledge\n\nLocal-first RAG knowledge base for Pi and OMP coding agents.\n\nIndex your codebase, docs, PDFs, URLs, and notes into persistent knowledge bases that Pi and [OMP](https://omp.sh/) can search across sessions. `pi-knowledge` combines semantic embeddings, BM25 keyword search, code-aware chunking, reranking, diagnostics, and stable large-project indexing so agents can answer from your actual project knowledge instead of guessing.\n\nBuilt as a native [Pi extension](https://pi.dev/docs/latest/extensions) with verified [OMP](https://omp.sh/) compatibility through the packaged extension entry. Designed for local-first project memory, agentic code search, and retrieval-augmented development workflows.\n\n## Why It Matters\n\nAgents lose project context between sessions and cannot fit large repositories into one prompt. `pi-knowledge` gives Pi and OMP durable, searchable project memory:\n\n- Search code and documentation by meaning, exact symbols, or both.\n- Look up lightweight code symbols, Markdown headings, config keys, and environment variables before broader search.\n- Keep private source data local by default.\n- Re-index changed files incrementally.\n- Diagnose stale, stuck, or low-quality indexes.\n- Handle large repositories with persisted progress instead of silent hangs.\n\nUnlike `pi-memory` (which manages the agent's own notes), `pi-knowledge` indexes **your existing files** and makes them semantically searchable by the agent.\n\n## Highlights\n\n- **Local-first project memory**: stores indexes under `~/.pi/knowledge/`; no project files are modified.\n- **Hybrid retrieval**: lexical-anchored BM25 + semantic vectors + normalized weighted score fusion, with semantic mode for vector-only conceptual recall.\n- **Code-aware indexing**: AST-aware chunking for TypeScript/JavaScript, Python, Go, Rust, and Java.\n- **Lightweight symbol lookup**: indexes functions, classes, interfaces, types, variables, route-like handlers, Markdown headings, config keys, and env vars for exact ","tagline":"Local-first RAG knowledge base for Pi agents with hybrid code/doc search, reranking, diagnostics, and large-project indexing.","category":"coding-agents","tags":["rag","knowledge-base","code-search","pi-extension","local-first"],"author":"nczz","verified":false,"attribution":{"status":"community_indexed","statusLabel":"Community indexed","shortLabel":"COMMUNITY INDEXED","sourceLabel":"OpenAgentSkill auto-indexer","sourceDetail":"nczz/pi-knowledge","creatorName":"nczz","creatorUrl":"https://github.com/nczz","sourceUrl":"https://github.com/nczz/pi-knowledge","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/nczz-pi-knowledge#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
