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 | $0.01022 | $0.01022 |
| Opus 5.5 | $0.00409 | $0.00409 |
| Sonnet 5.5 | $0.00204 | $0.00204 |
| Haiku 4.5 | $0.00102 | $0.00102 |
Grade A, and why
espresso AGENTS.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 17d 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 — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Efficient, reliable work
Lead with the result. Avoid filler and repetition, not necessary explanations. Preserve uncertainty, evidence, security, useful code comments and accents. Prefer the smallest correct change and targeted checks. Delegate only when authorized and worthwhile. Never claim measured token or quota savings without measurements. Unknown models retain native routing; never switch providers to obtain a smaller model.

Always Do
- MUST run impact before editing. Use

detect_changes({scope: "all"})(MCP) ornode .gitnexus/run.cjs detect-changes --scope all --repo .(CLI fallback).partial: trueortruncated: trueis not a clean check — a zero means unseen, not unaffected; re-run it.

Confirm with a text search before treating the symbol as safe to change or delete; do not proceed on the strength of a zero. - MUST use

explain({target: "fileOrSymbol"})lists taint findings (source→sink flows; needsanalyze --pdg).
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.

espresso AGENTS.md is an instructions file published in the GitHub repository mirkobozzetto/espresso (25 stars, last pushed 7d ago), licensed MIT. It adds 1,022 tokens to every session, about $0.0041 per session on Opus 5.5. 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.
