What is obsidian-ai-curator CLAUDE.md?

Repository instructions for an AI system that organizes and combines notes in an Obsidian vault. Obsidian is a note-taking app that stores linked notes as files.

Use them when developing or maintaining the Obsidian AI Curator and its note-management tools.

They explain how the AI assistant, MCP server, Obsidian plugin, cache, and note files work together, reducing guesswork during changes.

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.

Model	Per session	Once invoked
Fable 5.1	$0.03739	$0.03739
Opus 5.5	$0.01496	$0.01496
Sonnet 5.5	$0.00748	$0.00748
Haiku 4.5	$0.00374	$0.00374

Security

Grade A, and why

obsidian-ai-curator CLAUDE.md 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 2mo 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.

Obsidian AI Curator Project Instructions

This document provides context for AI assistants and developers working on the Obsidian AI Curator project - an AI-powered system that actively manages and consolidates notes in an Obsidian vault.

Project Vision

This project enables AI to be a true research partner and knowledge curator:

Active Curation: AI proactively finds, consolidates, and organizes scattered knowledge
"Tetris for Knowledge": Like pieces falling into place, fragments combine into coherent notes
Research Partnership: AI understands your research context and actively helps build knowledge

MCP Server provides tools for searching, reading, and writing notes
Obsidian Plugin adds native API access for better performance and accuracy
AI Integration enables Claude to understand vault structure and suggest improvements
Git Integration tracks changes and enables safe experimentation

Key Components

MCP Server (src/mcp-server.js): Core tool interface for vault operations
Obsidian Plugin (obsidian-ai-curator-plugin/): API server and consolidation UI
Tool Suite (src/tools/): Specialized tools for search, write, tags, projects, etc.
Obsidian API Client: Auto-detects and uses plugin when available

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.
