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 | $0.00071 | $0.02294 |
| Opus 5.5 | $0.00028 | $0.00918 |
| Sonnet 5.5 | $0.00014 | $0.00459 |
| Haiku 4.5 | $0.00007 | $0.00229 |
Grade A, and why
yuki scanned grade A with 1 finding 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 20d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Yuki (via Apideck)
Access Yuki through Apideck's Accounting unified API — one of 34 Accounting connectors that share the same method surface. Code you write here ports to Access Financials, Acumatica, banqUP and 30 other Accounting connectors by changing a single serviceId string. Apideck handles auth, pagination, rate limiting, and retries so you don't write per-tenant Yuki plumbing.
Beta connector. Yuki is currently in beta on Apideck. Expect partial resource coverage and occasional mapping gaps. Always verify coverage (see below) and fall back to the Proxy API for unsupported operations.

At a glance
- Implementation difficulty: moderate — API key authentication over SOAP
- Vendor partnership required: no — There is no app registration, review or partner agreement for Yuki's web services.
- Apideck-managed credentials: not available — Each consumer connects with their own web service key, so there is no shared Apideck application.
- Account type required: Yuki account on any bundle, including the free Minimal bundle, with web service access activated on the domain.
- Consumer access level: A user with the Portal administrator or Management role — only those roles can create web service keys.
- Sandbox: not available — Yuki's free Minimal bundle is a real account, not a test environment; there is no developer sandbox or demo administration.
- Costs: Free to 1,000 calls/day. Above that: EUR 10.50/month for 1,001-5,000 calls/day, EUR 105/month for 5,001-10,000 — added by the consumer's accountant.
- Rate limits: 1,000 web service calls per day per domain; paid add-ons raise the ceiling.
- Authentication: A WebserviceAccessKey; not OAuth, and no redirect for your consumer to complete.
- Webhooks: No webhooks — Yuki documents no event or subscription mechanism, and this connector adds no virtual webhooks, so poll for changes.
What ships with it
1 file 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.

yuki is a skill published in the GitHub repository apideck-libraries/api-skills (5 stars, last pushed yesterday), licensed Apache-2.0. It adds 71 tokens to every session and 2,294 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
