What is Kokoro-Engine AGENTS.md?

A set of development instructions for Kokoro Engine, a desktop application built with a web interface and a Rust backend. It describes the project folders, build commands, tests, and coding conventions.

Use it when developing or testing Kokoro Engine, including its interface, Rust commands, AI-related modules, desktop builds, and unit tests.

It gives a coding agent the repository-specific information needed to change the right part of the application and run the appropriate checks. This avoids treating the frontend and backend as if they used the same tools.

Token cost

What it costs to keep this loaded

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	$0.01053	$0.01053
Opus 5.5	$0.00421	$0.00421
Sonnet 5.5	$0.00211	$0.00211

Security

Grade A, and why

Kokoro-Engine 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 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.

Project Structure & Module Organization

Kokoro Engine is a Tauri v2 app with a React/TypeScript frontend and Rust backend. Frontend code lives in src/: main.tsx and App.tsx are entry points, src/components/ui holds primitives, src/features holds feature modules, src/lib holds bridge/services/tests, src/ui holds product UI/locales, and src/windows holds extra Tauri windows. Backend code lives in src-tauri/src: IPC is in commands, with domain modules such as llm, tts, stt, vision, mods, mcp, registry, characters, bot, and ai. Content packages are built from characters/ and mods/, registry artifacts live in registry/, the AstrBot adapter is in integrations/astrbot-kokoro/, and release/community evidence lives in docs/ and release-notes/.

Build, Test, and Development Commands

npm install: install JavaScript dependencies.
npm run tauri dev: run the full desktop app with Vite.
npm run dev: run the Vite frontend only.
npm run build: typecheck with tsc and build frontend assets.
npm run tauri build: build a distributable Tauri app.
npm test: run Vitest unit tests.
npm run check:ipc: verify the typed IPC command registry.
cargo test --manifest-path src-tauri/Cargo.toml: run Rust tests.
cargo clippy --manifest-path src-tauri/Cargo.toml --lib -- -D warnings: check Rust warnings before review.
node scripts/build-content-registry.mjs: rebuild deterministic registry archives and index.
cd integrations/astrbot-kokoro && pytest -q: run AstrBot adapter tests.

Coding Style & Naming Conventions

Use strict TypeScript, React function components, and @/* imports when they improve clarity. Match existing two-space TypeScript indentation and Rust rustfmt defaults. Name React components and TSX files with PascalCase, hooks as useSomething, utility files in local style such as audio-player.ts, and Rust modules/files with snake_case. Keep user-facing strings in src/ui/locales/*.json.

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.
