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 | $0.02407 | $0.02407 |
| Opus 5 | $0.01203 | $0.01203 |
| Sonnet 5 | $0.00481 | $0.00481 |
| Haiku 4.5 | $0.00241 | $0.00241 |
Grade A, and why
obsidian-ai-tagger-universe 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 259 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Development Skills
obsidian-plugin-dev
Use for Obsidian API and plugin development. Contains:
- Plugin API reference and TypeScript definitions
- UI components (Modal, Setting, ItemView, etc.)
- CSS variables for theming
- Best practices for plugin development
frontend-design
Use for UI/UX design and styling. Creates distinctive, production-grade interfaces with high design quality. Use when building modals, views, or improving visual components.
Language Requirements
All code comments and commit messages MUST be in English.
- Write all code comments in English only
- Write all git commit messages in English only
- Variable names, function names, and documentation should be in English
- The only exception is i18n translation strings (which contain Chinese translations)
Build Commands
# Development build with watch mode and inline sourcemaps
npm run dev
# Production build (type-checks, then bundles)
npm run build
# Version bump (updates manifest.json and versions.json)
npm run version
The build process uses esbuild to bundle src/main.ts into main.js. Production builds disable sourcemaps; dev builds enable inline sourcemaps.
Architecture Overview
Core Plugin Structure
Entry Point: src/main.ts (AITaggerPlugin class)
- Main plugin class extending Obsidian's
Plugin - Manages lifecycle: settings loading, LLM service initialization, command registration
- Handles tag operations:
analyzeAndTagNote(),showTagNetwork(), batch processing - Central coordinator between services, UI, and Obsidian API
Service Layer Architecture
LLM Services (src/services/)
- Base abstractions:
LLMServiceinterface defines contract for all providers - Two service types:
LocalLLMService: Ollama, LM Studio, LocalAI, OpenAI-compatible endpointsCloudLLMService: Cloud providers (OpenAI, Claude, Gemini, Groq, etc.)
- Adapter pattern (
src/services/adapters/): Each cloud provider has its own adapter (e.g.,claudeAdapter.ts,geminiAdapter.ts) handling API-specific formatting - Prompt engineering (
src/services/prompts/tagPrompts.ts): XML-structured prompts optimized for Claude/GPT with clear task/requirements/output sections
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.
