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 | $0.02496 | $0.02496 |
| Opus 5 | $0.01248 | $0.01248 |
| Sonnet 5 | $0.00499 | $0.00499 |
| Haiku 4.5 | $0.00250 | $0.00250 |
Grade A, and why
obsidian-claude-llm-wiki 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 11d 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 — 341 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.
What This Is
This is an Obsidian vault synced via iCloud. It is a personal knowledge base / notes workspace, not a software project.
Working with This Vault
- Notes are Markdown (
.md) files. Obsidian uses[[WikiLinks]]for internal links. - Canvas files use the
.canvasextension (JSON format). .obsidian/is gitignored — each user's Obsidian config is personal and generated automatically.
obsidian-headless Tool (ob)
The ob CLI (obsidian-headless) handles authentication and account-level operations.
ob login— show authenticated user
Obsidian CLI (obsidian)
The obsidian CLI provides full programmatic access to the vault. Obsidian must be running for commands to work. Supports vault=<name> option to target a specific vault.

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.
