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.

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 | $0.02468 |
| Opus 5.5 | $0.00028 | $0.00987 |
| Sonnet 5.5 | $0.00014 | $0.00494 |
| Haiku 4.5 | $0.00007 | $0.00247 |
Grade A, and why
exact-online 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 13d 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 — 184 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Exact Online (via Apideck)
Access Exact Online 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 Exact Online plumbing.

At a glance
- Implementation difficulty: moderate — Paid Developer Subscription + App Review Required for External Consumers
- Vendor partnership required: yes (developer portal) — Registering your app requires a paid Exact Online developer subscription (per country); App Store listing is optional.
- Apideck-managed credentials: not available
- Account type required: Active Exact Online subscription in any supported country edition (NL, BE, DE, ES, UK, US)
- Consumer access level: Any user who can authorise third-party app connections; at consent time the app must be granted access to each division (administration) it needs to access.
- Sandbox: available — Test with your developer subscription or a free 30-day trial; every environment holds live data.
- Costs: Developer subscription approx. €15/month per country (excl. VAT); no per-call API charges.
- Rate limits: 60 requests/minute and 5,000 requests/day per app per division; Exact Online Premium raises the daily cap to 30,000.
- Authentication: Authorization Code flow.
- Webhooks: No webhooks — sync is polling-based; Exact Online's native webhooks are not surfaced through this connector.
Important to know:
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.
