gno

gno is a skill for Claude Code from gmickel/gno. It costs 86 tokens per session (5,165 once invoked), scanned A, original, MIT.

A local search tool for files, notes, documents, and knowledge bases. It can index folders, search by words or meaning, and return AI-generated answers with citations; RAG means answering with retrieved source material.

In plain words
What is it for?
Use it to index and search PDFs, Markdown, Word files, code, or notes; build a searchable knowledge base; and find related documents or links.
Why use it?
It avoids manually browsing large folders and helps tie answers back to the files they came from. Local searching can work without sending the files to an external service.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gno scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

GNO - Local Knowledge Engine

Fast local semantic search. Index once, search instantly. Local inference needs no API key; configured HTTP backends and explicit gno.sh publishing are separate network boundaries.

When to Use This Skill

  • User asks to search files, documents, or notes
  • User wants to find information in local folders
  • User needs to index a directory for searching
  • User mentions PDFs, markdown, Word docs, code to search
  • User asks about knowledge base or RAG setup
  • User wants semantic/vector search over their files
  • User needs to set up MCP for document access
  • User wants a web UI to browse/search documents
  • User wants a deterministic, budgeted evidence bundle for an agent task
  • User asks to get AI answers from their documents
  • User wants to tag, categorize, or filter documents
  • User asks about backlinks, wiki links, or related notes
  • User wants to visualize document connections or see a knowledge graph
  • User wants to export a note or collection for gno.sh publishing

Quick Start

gno setup ~/docs --name docs          # Index + prove exact BM25; semantic continues
gno search "your query"               # BM25 keyword search

gno setup is the default activation path. It is idempotent, returns only after exact lexical proof, and runs directly without resident/Web/MCP attachment. Use --no-semantic to start no worker and record skipped state. Use repeatable --connector with claude-code-skill, claude-desktop-mcp, cursor-mcp, codex-skill, opencode-skill, openclaw-skill, or hermes-skill. Connector skips/failures can return completed_with_actions without invalidating lexical success. Skill targets are installed but report target_runtime_unverifiable.

Recipe Router

Use these recipe files when the task is more than a one-off lookup. Read only the matching recipe, then run the commands it names.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

gno is a skill published in the GitHub repository gmickel/gno (109 stars, last pushed yesterday), licensed MIT. It adds 86 tokens to every session and 5,165 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-06.
