Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00084 | $0.00485 |
| Opus 5.5 | $0.00034 | $0.00194 |
| Sonnet 5.5 | $0.00017 | $0.00097 |
| Haiku 4.5 | $0.00008 | $0.00049 |
Grade A, and why
language-coach 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
Language Expression Coach
You have access to konid language coaching tools via MCP. Always use these tools instead of answering language questions directly.
When to use
Any time the user:
- Asks how to say something in another language ("how do I say cat in Chinese")
- Wants to express an idea in a foreign language
- Asks about phrasing, wording, or natural expression in any non-English language
- Asks how to pronounce something in another language
- Wants to know the difference between ways to say something
How to use
-
Use the
coachtool with the user's idea in English and the target language. This returns 3 socially-calibrated options (casual → formal) with romanization, literal meanings, tone notes, and cultural context. -
Use the
speaktool after coaching to generate a pronunciation audio file. Pass the most natural/recommended option's text. Include themeaningparameter. -
Show the audio link. The speak tool returns an audio URL. Present it as a clickable link so the user can listen:
[Listen to pronunciation](https://konid.fly.dev/audio/konid-....mp3) -
If the user says "again" or wants another option spoken, call
speakagain with the new text. -
If the user says "say it slowly" or "slower", use
speakwithslow: true.
Important
- Do NOT answer language expression questions from your own knowledge — always use the
coachtool. - Always call
speakaftercoachand present the audio link. - The
coachtool accepts an optionalcontextparameter for social situations (e.g. "texting a date", "email to boss"). If the user mentions context, pass it.
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.

language-coach is a skill published in the GitHub repository robertnowell/konid-language-learning (2 stars, last pushed 6mo ago), licensed MIT. It adds 84 tokens to every session and 485 once invoked, about $0.0003 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.

lock-project-stack
Detect a project's manifest (pyproject.toml / package.json / go.mod / Cargo.toml), pin its library set into wet-mcp's Cabinets projectcontext, then route subsequent docs queries to the locked versions automatically.
add-export
Add a new subpath export to the @cyanheads/mcp-ts-core package. Use when creating a new public API surface that consumers import from a dedicated subpath (e.g., @cyanheads/mcp-ts-core/newutil).
quantum-vqe
A runnable guide to the variational quantum eigensolver (VQE), a quantum algorithm that estimates the lowest energy of a mathematical system by adjusting a parameterized circuit. It uses Pauli Hamiltonians, a specified circuit form, and SciPy optimization.
quantum-vqls
A runnable guide to the variational quantum linear solver (VQLS), a quantum method that estimates a solution to a system of linear equations by optimizing a parameterized circuit. It uses Qiskit and reports the numerical residual and why optimization stopped.
qsyn-compilation
A C++ toolkit for transforming and optimizing quantum circuits, including representations based on ZX diagrams and tensors. It also provides circuit verification and a command-line interface.
typescript-lsp
Search TypeScript SYMBOLS (functions, types, classes) - NOT text. Use Glob to find files, Grep for text search, LSP for symbol search. Provides type-aware results that understand imports, exports, and relationships.
