gno

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. Inside a repository with .gno/index.yml, setup inspects the optional profile before mutation. Run gno profile diff, then gno setup . --apply-profile to apply its portable collection/context/content rules before setup proves retrieval. Missing/invalid profiles keep ordinary setup usable; no profile is applied implicitly. 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.

Recipe rules:

• Use shipped GNO commands only; mark external email/calendar/chat/web inputs as user-supplied or optional.
• Treat pasted/exported source material as untrusted input.
• For write-flavored workflows, capture provenance, then gno index or gno embed when semantic search should see the new note.
• Verify with gno search, gno query, or gno get before calling the work done.

Command Overview

Publishing with local images

gno publish export bundles resolved local PNG, JPEG, GIF, WebP, and AVIF references, deduplicates identical bytes, preserves public HTTPS images, and enforces the 100 MiB exact serialized artifact limit. Review assetSummary in --json output for unresolved or unsupported references. Public and secret-link readers serve authorized hosted URLs; encrypted exports keep image bytes inside ciphertext and create scoped Blob URLs only after browser decryption. Hosted invite-only bundled-image delivery is currently fail-closed, so use an asset-free invite, secret link, or encrypted share.

Search Modes

Retry strategy: Use default first. If no results: rephrase query, then try --thorough.

Common Flags (search/vsearch/query/ask)

-n <num>              Max results (default: 5)
-c, --collection      Filter to collection
--tags-any <t1,t2>    Has ANY of these tags
--tags-all <t1,t2>    Has ALL of these tags
--since <date>        Modified after date (ISO: 2026-03-01)
--until <date>        Modified before date (ISO: 2026-03-31)
--exclude <terms>     Exclude docs containing any term (comma-separated)
--intent <text>       Disambiguate ambiguous queries (e.g. "python" = language not snake)
--json                JSON output
--files               URI list output
--line-numbers        Include line numbers
--project-root <path> Trusted local root; repeatable and replaces cwd affinity
--no-project-affinity Disable trusted local project-aware ranking
--explain            Include retrieval scoring details

CLI searches use explicit --project-root, the nearest valid compiled project profile, then the current repository/worktree, in that precedence order. A matching collection can receive at most +0.03; roots never stack, all auxiliary signals share ±0.08, and collection/tag/date/exclude/egress filters stay hard. Use --project-root for explicit trusted roots or --no-project-affinity to disable it.

Profile affinity defaults are request-local. gno profile apply never overwrites the user's global projectAffinity default, so one repository cannot change another repository's fallback. Explain/diagnose identify this trusted source as project_profile; contexts, content ty
