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 | $0.00000 | $0.00269 |
| Opus 5.5 | $0.00000 | $0.00108 |
| Sonnet 5.5 | $0.00000 | $0.00054 |
| Haiku 4.5 | $0.00000 | $0.00027 |
Grade A, and why
prep 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 1mo 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 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.

prep is a command published in the GitHub repository phuryn/pm-brain (938 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 269 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other commands, from other repositories
youtube
Extract transcript, metadata, and top comments from a YouTube video - summarized via Gemini (free tier) or Grok and saved to vault. Add --visual to also read the video's frames (scene detection).
obsidian-retrieval-eval
Measure how well vault search finds the right note for a natural-language question - recall@k and MRR, with the concrete failures.
x-read
Deep-read an X (Twitter) post via Grok xsearch - verbatim post, thread, TL;DR, claims, reply sentiment, voices to watch.
obsidian-checkin
Ask the owner whether old people and project notes still hold - shows what each note says and when it was last checked, re-asks until answered, saves the news.
obsidian-distill
Condense a long note or source into key claims, each tagged with provenance back to the exact source block it came from.
obsidian-merge
Merge two near-duplicate notes found by /obsidian-health into one - dry run by default, redirects the retired note rather than deleting it.
