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 | $0.00342 | $0.00342 |
| Opus 5 | $0.00171 | $0.00171 |
| Sonnet 5 | $0.00068 | $0.00068 |
| Haiku 4.5 | $0.00034 | $0.00034 |
Grade A, and why
headroom-desktop 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.
What it actually says
AGENTS.md - headroom-desktop
Canonical agent guidance for this repo lives in CLAUDE.md (same directory). Read it before changing code; it holds the project invariants (testing rules, persistence rules, wheel-bump rules, styling/token rules, formatting). This file only adds the quickstart every agent needs.
What this is
Tauri desktop app (Rust backend in src-tauri/src/, React/TS frontend in
src/) that routes Claude Code / Codex / OpenCode through a local
token-optimization proxy. See README.md for architecture and the proxy
topology (ports 6767/6768).
Commands
npm install && npm run tauri dev # run the app
cargo test --manifest-path src-tauri/Cargo.toml --lib <filter> # Rust tests
cargo check --manifest-path src-tauri/Cargo.toml # cross-module changes
npx tsc --noEmit # frontend types
npx vitest run # frontend tests
./scripts/check-colors.sh # CSS token gate (CI-enforced)
./scripts/check-no-console.sh # console.log gate (CI-enforced)
Large files warning
tool_manager.rs (~12k lines), state.rs (~9k), lib.rs (~7.3k),
client_adapters.rs (~5k), and src/App.tsx (~7.7k) are too big to read
whole. Locate symbols with grep -n, then read only the region you edit.
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.
