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 | $0.00453 | $0.00453 |
| Opus 5.5 | $0.00181 | $0.00181 |
| Sonnet 5.5 | $0.00091 | $0.00091 |
| Haiku 4.5 | $0.00045 | $0.00045 |
Grade A, and why
OpenNOW copilot-instructions.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 1mo 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
Copilot instructions for OpenNOW
Follow the repository's AGENTS.md for architecture, ownership, testing and localization rules.
Project scope
- The only supported desktop application is
opennow-qt/(Qt 6, C++20 and QML). native/opennow-core/owns settings, credentials, GFN orchestration and application services.native/opennow-streamer/owns the in-process NVST streaming runtime consumed through its C ABI.- Qt talks to the Rust core through the versioned JSON protocol in
docs/core-protocol.md. - The root
package.jsonprovides optional command aliases and localization tooling. Node is not part of the desktop runtime, and there is no Electron application to build or restore.
Build and checks
Run from the repository root:
cmake -S opennow-qt -B build/opennow-qt -DCMAKE_BUILD_TYPE=Debug
cmake --build build/opennow-qt
ctest --test-dir build/opennow-qt --output-on-failure
cargo test --manifest-path native/opennow-core/Cargo.toml
cargo test --manifest-path native/opennow-streamer/Cargo.toml --workspace
npm run locales:check
Run the narrowest affected tests first. For Rust edits, also run the workspace's cargo fmt
check and cargo clippy --all-targets -- -D warnings (with --workspace for the streamer).
See opennow-qt/README.md and docs/qt-acceptance.md for smoke and hardware acceptance checks.
Key conventions
- Keep UI in QML and native integration in narrowly owned C++/Rust types.
- Keep GFN authentication, session refresh and error normalization in the Rust core.
- Update all producers, consumers, fixtures and version checks when changing JSON or C ABI contracts.
- Keep the native video item alive under overlays; handle local shortcuts before gameplay input.
- Preserve legacy data import and stable device IDs when changing persistence.
- Edit only
locales/en.jsonfor localized copy; other locale files are generated by Crowdin.
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.
