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 | $0.00075 | $0.02384 |
| Opus 5.5 | $0.00030 | $0.00954 |
| Sonnet 5.5 | $0.00015 | $0.00477 |
| Haiku 4.5 | $0.00007 | $0.00238 |
Grade A, and why
zoho-books 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 — 187 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Zoho Books (via Apideck)
Access Zoho Books 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 Zoho Books plumbing.
Quick facts
- Apideck serviceId:
zoho-books - Unified API: Accounting
- Auth type: oauth2
- Gotchas: page
- Zoho Books docs: https://www.zoho.com/books/api/v3/
- Homepage: https://www.zoho.com/books/
At a glance
- Implementation difficulty: straightforward — Self-Service OAuth, No Partnership Required
- Vendor partnership required: no — No partner programme — self-service OAuth client registration is free. An optional Zoho Marketplace listing adds discoverability, not API access.
- Apideck-managed credentials: available — For testing: the OAuth consent screen shows "Apideck"; use your own Zoho OAuth client for production.
- Account type required: Active Zoho Books subscription (Free plan or higher)
- Consumer access level: A user with organization-level access in the Zoho Books organization being authorized
- Sandbox: not available (signup) — Start a free Zoho Books trial or add a dedicated test organization to your own account; there is no separate sandbox environment.
- Costs: Free — Zoho charges nothing for API access on any Zoho Books plan, including the Free plan.
- Rate limits: 100 requests/minute per organization; daily cap set by the consumer's plan (1,000 Free to 10,000 Premium); 5 concurrent calls on Free, 10 on paid plans.
- Authentication: Authorization Code flow.
- Webhooks: Virtual webhooks — created/updated/deleted events on 10 resources, including invoices, bills, payments, customers and suppliers.
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.
