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 | $0.01728 | $0.01728 |
| Opus 5.5 | $0.00691 | $0.00691 |
| Sonnet 5.5 | $0.00346 | $0.00346 |
| Haiku 4.5 | $0.00173 | $0.00173 |
Grade A, and why
omamail 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 7d 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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Structure and boundaries
- Group by module, not file type. Rust lives in
src/, CLI handling insrc/cli/, and dispatch insrc/backend/. QML and its JavaScript live together underui/. Rust unit tests live with their modules; UI tests live inui/tests/; integration tests live intests/. - Rust owns mail business logic and durable agent jobs. QML owns presentation and interaction state, communicating with the persistent backend over stdin/stdout rather than invoking CLI commands. See
docs/BACKEND.mdanddocs/ARCHITECTURE.md. - QML JavaScript libraries start with
.pragma libraryand usevarandfunction, notconst,let, arrows or template literals. Put testable presentation rules there. Tests load module paths, e.g.load("cache/Cache.js");ui/tests/load.jsresolves QML.importchains. - A list or object received through a
varsignal argument (on Qt 6.12) or a delegate'smodelDatais a sequence or reference object, not a JavaScript array or object:Array.isArraysays no and its keys come back sorted. A receiver that judges such a value, keeps it or writes to it takesPlain.plain(ui/backend/Plain.js) of it first;ui/tests/qml/tst_signal_lists.qmlshows the pattern. - List new QML files in the Makefile's lint inputs and import other modules explicitly.
Service.qmlis shell-constructed and must declare no required properties. The shell injects onlyshell,manifest,pluginRegistry, andbarWidgetRegistry; settings arrive through the bar widget'sapplySettings.
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.

omamail AGENTS.md is an instructions file published in the GitHub repository huacnlee/omamail (313 stars, last pushed yesterday), licensed MIT. It adds 1,728 tokens to every session, about $0.0069 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.
