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.

What it costs to keep this loaded
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 | $0.00039 | $0.02057 |
| Opus 5 | $0.00019 | $0.01028 |
| Sonnet 5 | $0.00008 | $0.00411 |
| Haiku 4.5 | $0.00004 | $0.00206 |
Grade A, and why
quickbooks-online 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 12d 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.

QuickBooks Online Integration Skill
Overview
Integrates a small business with QuickBooks Online for customer management, estimates, invoices, and payment tracking. Uses Intuit's OAuth 2.0 flow with automatic token refresh. Designed for agent-mediated use: owners text commands, agent executes QB API calls.
When to Use
- Create/send estimates from estimator-engine output
- Convert estimates to invoices when job is booked
- Record payments (Stripe webhook → QB payment)
- Sync customers between CRM and QB
- Pull reports for weekly owner summary (AR aging, revenue, outstanding estimates)
Don't Use For
- Complex inventory/assembly tracking
- Multi-currency or multi-entity accounting
- Payroll or tax filing
Authentication (OAuth 2.0)
Required Credentials (Environment Variables)
QBO_CLIENT_ID=*** From Intuit Developer Dashboard
QBO_CLIENT_SECRET= # From Intuit Developer Dashboard
QBO_REDIRECT_URI= # e.g., https://your-domain.com/qbo/callback
QBO_ENVIRONMENT= # "sandbox" or "production"
QBO_COMPANY_ID= # Realm ID (set after first auth)
Token Storage
- Store access_token + refresh_token + realm_id in
~/.hermes/qbo_tokens.json - Auto-refresh: access_token expires in 1 hour; refresh_token expires in 101 days
- On 401: refresh token, retry once, then force re-auth if refresh fails
Auth Flow
- User visits:
https://appcenter.intuit.com/connect/oauth2?client_id={id}&redirect_uri={uri}&scope=com.intuit.quickbooks.accounting&response_type=code&state={random} - Callback receives
code+realmId - Exchange code for tokens:
POST https://oauth.platform.intuit.com/oauth2/v1/tokens/bearer - Store tokens + realm_id
Core API Operations
Customers
# Create customer (from CRM lead)
POST /v3/company/{realmId}/customer
{
"DisplayName": "John Smith",
"PrimaryEmailAddr": {"Address": "[email protected]"},
"PrimaryPhone": {"FreeFormNumber": "555-555-0123"},
"BillAddr": {"Line1": "123 Main St", "City": "[CITY]", "CountrySubDivisionCode": "[STATE]", "PostalCode": "[ZIP]"},
"Notes": "Lead from referral"
}
# Query customer
GET /v3/company/{realmId}/query?query=SELECT * FROM Customer WHERE DisplayName='John Smith'
What ships with it
3 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.
