ChatGPT MD is an Obsidian plugin that lets users chat with AI inside their notes, reference notes through wiki links, and optionally let the AI search the vault, read notes, or browse the web with approval. It is for writers and developers who want cloud or locally hosted AI assistance while keeping their work in an Obsidian vault. The catalogue entries provide instructions for using the plugin.

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 | $0.00060 | $0.00060 |
| Opus 5.5 | $0.00024 | $0.00024 |
| Sonnet 5.5 | $0.00012 | $0.00012 |
| Haiku 4.5 | $0.00006 | $0.00006 |
Grade A, and why
chatgpt-md 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.
What it actually says
CLAUDE.md
This file exists only for backward compatibility with tooling that looks for CLAUDE.md.
The authoritative agent instructions live in AGENTS.md — read that file instead,
including the per-directory AGENTS.md files throughout the source tree.
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.
