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 | $0.02743 |
| Opus 5.5 | $0.00028 | $0.01097 |
| Sonnet 5.5 | $0.00014 | $0.00549 |
| Haiku 4.5 | $0.00007 | $0.00274 |
Grade A, and why
quickbooks 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 7d 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.

QuickBooks (via Apideck)
Access QuickBooks 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 QuickBooks plumbing.
Quick facts
- Apideck serviceId:
quickbooks - Unified API: Accounting
- Auth type: oauth2
- Gotchas: page
- QuickBooks docs: https://developer.intuit.com/app/developer/qbo/docs
- Homepage: https://quickbooks.intuit.com/
At a glance
- Implementation difficulty: moderate — Self-Service Signup + App Review Required
- Vendor partnership required: yes (Intuit Developer Portal) — Intuit Developer Account required (free, self-service).
- Apideck-managed credentials: available — OAuth shows "Apideck" as the requesting application.
- Account type required: QuickBooks Online (Simple Start, Essentials, Plus, or Advanced)
- Consumer access level: Any user with QuickBooks Online access (Admin recommended for full data access)
- Sandbox: available (signup) — Free sandbox via Intuit Developer Portal (up to 10 companies, valid for 2 years).
- Costs: Reads are metered, writes are not: Builder is free with 500K CorePlus calls/month then blocks; Silver $300/month includes 1M.
- Rate limits: 500 requests/minute per company (realm) and 10 concurrent requests/second per realm and app. Enforced on every tier; upgrading does not raise them.
- Authentication: Authorization Code flow.
- Webhooks: Native — invoice, customer, and payment events (20+ event types)
Important to know:
- Only successful production calls (list/get-one, query, reports, attachment downloads) count as CorePlus; sandbox/OAuth never do. Builder's free cap blocks calls outright until reset, not throttled — a payment method moves you to Silver, which bills overage instead.
- Intuit's platform fees fall on whoever owns the Intuit app, not on the end QuickBooks company. Apideck-provided credentials are for evaluation and testing; a production integration uses your own Intuit app, so the tier and any fees are yours.
- The projects resource is served by Intuit's Projects API, which is a Premium API available only to Silver, Gold and Platinum partners. On the free Builder tier this resource is unavailable regardless of your CorePlus allowance.
- Intuit refresh tokens expire after 100 days of inactivity and, since a November 2025 policy change, after a hard maximum of 5 years regardless of activity. Dormant and aged-out connections need consumer re-authorization.
- Intuit sometimes returns errors on healthy connections: a SystemFault, a company lockout (codes 100/140, LOCKED_BY_SERVER) or a 400 Permission Denied (code 5020). Apideck treats these as transient and keeps the connection valid, so no reconnect is needed. Retry after a backoff.
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.

quickbooks 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 2,743 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.
