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 | $0.36606 | $0.36606 |
| Opus 5.5 | $0.14642 | $0.14642 |
| Sonnet 5.5 | $0.07321 | $0.07321 |
| Haiku 4.5 | $0.03661 | $0.03661 |
Grade A, and why
Victauri 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 4d 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.

Victauri — Claude Code Instructions
What Is Victauri
Victauri — Verified Introspection & Control for Tauri Applications.
X-ray vision and hands for AI agents inside Tauri apps. A browser tool with JS eval can poke a Tauri backend (Tauri exposes window.__TAURI_INTERNALS__.invoke, so it can invoke commands) — but only Victauri can read it safely. The database and the command registry have no eval_js equivalent — the backend tools read them through direct AppHandle access, independent of the webview; the IPC history is captured with request and response bodies (a browser's Performance API reports only HTTP 200 and exposes no bodies). And on macOS WKWebView / Linux WebKitGTK there is no Chrome DevTools Protocol surface for a CDP-based tool to attach to (those engines have their own, separate remote-inspector protocols; only WebView2 on Windows exposes a CDP-class surface). Victauri is one integration that sits inside the process on both sides of the boundary, giving agents simultaneous read-only access to the webview DOM, the Rust backend, the IPC layer, the database, and native window state — through a single MCP interface.
Stack: Pure Rust workspace (6 crates) | Target: Tauri 2.0 applications
Browser mode removed (2026-06-09). The
victauri-browsercrate + Chrome/Firefox extensions + npm package (@4da/victauri-browser) — an exploration to inspect any website — were deleted: off-thesis (Victauri's moat is being inside the Tauri process, where CDP/Playwright can't attach), the highest-risk surface (the only hostile-page boundary), and unused. Browser automation is better served by Playwright/CDP. Some deep historical "Current State" entries below still describe it as past context.

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.

Victauri CLAUDE.md is an instructions file published in the GitHub repository 4DA-Systems/Victauri (6 stars, last pushed 4d ago), licensed Apache-2.0. It adds 36,606 tokens to every session, about $0.1464 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 2026-08-31.
