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 | $0.00045 | $0.02397 |
| Opus 5 | $0.00023 | $0.01198 |
| Sonnet 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 3d 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 (12,923 stars, last pushed yesterday), licensed MIT. It adds 45 tokens to every session and 2,397 once invoked, about $0.0002 per session on Opus 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.
