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 | $0.00974 | $0.00974 |
| Opus 5.5 | $0.00390 | $0.00390 |
| Sonnet 5.5 | $0.00195 | $0.00195 |
| Haiku 4.5 | $0.00097 | $0.00097 |
Grade A, and why
vibemon-app 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 12d 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 — 42 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repository Guidelines
Project Structure & Module Organization
VibeMon is an Electron desktop application. The main process starts in src/main.js; CommonJS services live in src/modules/, shared registries in src/shared/, and renderer code in src/renderer.js, src/shared/bubble/, and src/engine/. The macOS widget feed lives in src/widgets/, and the WidgetKit extension in native/macos/ (see docs/widgets.md). Keep tests in tests/, documentation in docs/, character art in src/assets/characters/, and application icons in assets/.
Architecture & Data Flow
Local HTTP and scoped cloud polling updates converge at routeStatusUpdate() and flow through CharacterWindowManager to one retargetable character window and speech bubble. Preserve this ingress and focus-selection behavior. This public repository owns the state/character registries, character art, shared rendering modules, hooks, and Python collector. web-distribution.json maps their source paths to the public files consumed by private Web. Keep timeouts and sizes in src/shared/data/constants.json (_MS for milliseconds). The renderer CSP requires local Three.js files; do not use runtime CDN imports — src/renderer.js passes the vendored three.js namespace to the 3D engine as options.THREE.
Build, Test, and Development Commands
Use Node.js 26.11.1 from .nvmrc and pnpm:
pnpm installinstalls dependencies.pnpm startlaunches the Electron app locally.pnpm lintchecks JavaScript and CommonJS files with ESLint.pnpm testruns the Jest suite once;pnpm test:watchreruns affected tests during development.pnpm test:coveragewrites coverage reports tocoverage/.pnpm preview:widgetsbuilds the macOS widgets with Xcode and renders their states toout/widgets/preview.png.pnpm buildcreates platform packages without publishing. Usepnpm build:mac,pnpm build:win, orpnpm build:linuxfor a specific target.pnpm check:registryvalidates local registry fields, image references, and dimensions.pnpm check:distributionvalidates the public export map without network or private credentials.pnpm build:distributionwrites the reviewed installer/static payload todist/web/.python3 -m pytest tests/hooks collector/testschecks hooks and collector behavior (install pytest and./collectorin a virtual environment first).
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.
