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 | $0.03282 | $0.03282 |
| Opus 5 | $0.01641 | $0.01641 |
| Sonnet 5 | $0.00656 | $0.00656 |
| Haiku 4.5 | $0.00328 | $0.00328 |
Grade A, and why
Ventus 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 8d 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 — 253 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Ventus Agent Context
Read this before changing the code. Ventus is a Rust desktop browser for Windows, built with Tao, Wry, WebView2, SQLite, and a custom HTML/CSS/JS chrome.
Project Shape
Ventus is not a normal web app. It is a native Rust process that owns a frameless desktop window and several WebView2 child windows.
src/main.rsis only the binary entry point. It callsruntime::run().src/runtime/owns process startup, the Tao event loop, WebView creation, Win32 layout/clipping, downloads, update downloads, and dispatchingTabActions.src/app.rsownsAppState, most browser command handling, state serialization for the chrome UI, settings persistence, history/bookmark/download updates, and navigation decisions.src/ui/chrome.rsbuilds the chrome document and owns its Rust tests.src/ui/chrome.htmlcontains the browser interface, CSS, and JavaScript compiled into the executable.src/ui/events.rsdefines the IPC contract between JS and Rust withChromeCommandandAppEvent.src/browser/contains tab, workspace, navigation, search-engine, downloads, and split-view models.src/storage/contains SQLite setup, migrations, repositories, keychain access, and settings serialization.src/ai/contains the AI provider abstraction and OpenAI, OpenRouter, Anthropic, and Ollama adapters.src/updater.rschecks GitHub releases forneura-spheres/Ventus, downloads a Windows.exe, and applies it through a temporary batch file.public/ventus.pngis the logo source used in the chrome and app icon generation.build.rscreatesassets/logo.icofrom the PNG and attaches it as the Windows resource icon.
Some local checkouts may include RULES.md with stricter project style notes. If it is present, read it before coding. Otherwise, follow the conventions in this file and the surrounding source.
Runtime Source Map
The runtime fragments use include! from src/runtime/mod.rs. This keeps them in one Rust module scope, so the refactor does not change private visibility or event-loop captures.
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.

Ventus AGENTS.md is an instructions file published in the GitHub repository neura-spheres/Ventus (2 stars, last pushed 10d ago), licensed MIT. It adds 3,282 tokens to every session, about $0.0164 per session on Opus 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 2026-08-31.
