MiMoCode is a terminal-based AI coding assistant that reads and writes code, runs commands, manages Git, and remembers project context across sessions. Developers use it to work with software projects through a command-line interface and connect it to language-model providers; the catalogue includes skills and instructions for it.

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 | $0.00008 | $0.00161 |
| Opus 5.5 | $0.00003 | $0.00064 |
| Sonnet 5.5 | $0.00002 | $0.00032 |
| Haiku 4.5 | $0.00001 | $0.00016 |
Grade A, and why
effect 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 2mo 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
Effect
This codebase uses Effect, a framework for writing typescript.
How to Answer Effect Questions
- Clone the Effect repository:
https://github.com/Effect-TS/effect-smolto.opencode/references/effect-smolin this project NOT the skill folder. - Use the explore agent to search the codebase for answers about Effect patterns, APIs, and concepts
- Provide responses based on the actual Effect source code and documentation
Guidelines
- Always use the explore agent with the cloned repository when answering Effect-related questions
- Reference specific files and patterns found in the Effect codebase
- Do not answer from memory - always verify against the source
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.

effect is a skill published in the GitHub repository XiaomiMiMo/MiMo-Code (13,737 stars, last pushed today), licensed MIT. It adds 8 tokens to every session and 161 once invoked, about $0.0000 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 2026-08-30.
