Search Vault is an agent skill from Abilityai/cornelius. Quick search across Obsidian vault using keywords or semantic similarity
Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Knowledge Management. It works with Obsidian. The repository describes itself as: AI-powered second brain template for Claude Code + Obsidian. The licence is MIT.
3 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit b9bea90. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepBashFrom allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash and markdown).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Search Vault loads about 657 tokens when it runs. Until then it costs about 21 tokens; SKILL.md has 216 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check noted patterns worth knowing about, such as sudo or a known installer.
allowed-tools: Read, Grep, BashAutomated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Use Local Brain Search for all semantic search operations. Supports two modes:
Note: Usage-based learning is active - searches are tracked and rankings improve over time.
$ARGUMENTS
Semantic Search - Use Local Brain Search:
# For quick lookups, use static mode

Quick search across Obsidian vault using keywords or semantic similarity. Search Vault is an agent skill from Abilityai/cornelius.
Search Vault fits situations like: knowledge Management work in your project.
Run `npx skills add Abilityai/cornelius --skill search-vault -a claude-code`. Or copy the skill folder (.claude/skills/search-vault in Abilityai/cornelius) into .claude/skills/search-vault in your project. Claude Code loads it when a task matches its description.
Run `npx skills add Abilityai/cornelius --skill search-vault -a codex`. Or copy the skill folder (.claude/skills/search-vault in Abilityai/cornelius) into .agents/skills/search-vault in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Abilityai/cornelius --skill search-vault -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/search-vault, .gemini/skills/search-vault, .github/skills/search-vault and .opencode/skills/search-vault in your project.
SKILL.md names no scripts, command-line tools or credentials: Search Vault is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Grep, Bash.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
Search Vault is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 657 tokens (SKILL.md is roughly 2.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Search Vault: Obsidian CLI (Atmosphere/atmosphere, 3.8k stars), Obsidian Canvas Boards (AgriciDaniel/claude-obsidian, 15k stars), LLM Wiki (lewislulu/llm-wiki-skill, 655 stars) and Second Brain (NicholasSpisak/second-brain, 737 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Abilityai (a GitHub organization) maintains it in Abilityai/cornelius, which has 109 GitHub stars. The repository holds 54 skills in this directory. The repository was last updated on October 8, 2026.
