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.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Agent Snooping · line 18 Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.
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 | $0.00045 | $0.02397 |
| Opus 5.5 | $0.00018 | $0.00959 |
| Sonnet 5.5 | $0.00009 | $0.00479 |
| Haiku 4.5 | $0.00005 | $0.00240 |
Grade A, and why
build-business-case 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.
How it starts
The opening of the file, as written. The whole thing — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Build Business Case
Turn uneven account evidence into a customer-led, decision-useful value case. This skill owns the business-case logic and drafts; it is not generic product positioning, a presentation-design workflow, or a writeback workflow.
Start with the customer, not the product. Follow this chain on every run:
customer context -> account-native anchor -> workflow -> use case -> value drivers -> metrics -> quantified impact -> narrative -> public research when useful
If the evidence cannot support credible math, produce a clearly labeled structural case and the smallest validation plan needed to make it finance-ready.
Common Skill Instructions
MANDATORY: If not already in context, read and adhere closely to plugins/sales/skills/index/SKILL.md## Cross-Skill Best Practices.
Key Dependency Categories
Use only lanes that materially improve the case.
- [Blocking] ~~CRM for authoritative account, opportunity, owner, stage, amount, close timing, contacts, and commercial context. It blocks customer/account-specific cases unless authoritative account and commercial context is already grounded; generic scenario cases can proceed without it.
- ~~Meeting Transcripts for discovery evidence, stakeholder language, workflow pain, objections, quantified claims, decisions, and validation gaps
- ~~Knowledge & Files for account plans, source packs, discovery notes, prior value cases, proof points, and account-native metrics
- ~~Sales Intelligence only when company, fit, stakeholder, or market context closes a specific evidence gap
Use public research only when it sharpens strategic priorities, executive wording, operating pressure, or “why now.” Prefer company-controlled, investor, regulatory, and other primary sources. Never let public or enrichment context substitute for customer-confirmed pain, workflow metrics, decision process, or CRM-owned truth.
Reference Loading
SKILL.md owns the normal customer-led flow, evidence order, guardrails, and default package. Load references only when their extra detail matters:
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

build-business-case is a skill published in the GitHub repository XiaomiMiMo/MiMo-Code (13,681 stars, last pushed today), licensed MIT. It adds 45 tokens to every session and 2,397 once invoked, about $0.0002 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.
