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 | $0.01834 |
| Opus 5.5 | $0.00028 | $0.00734 |
| Sonnet 5.5 | $0.00014 | $0.00367 |
| Haiku 4.5 | $0.00007 | $0.00183 |
Grade A, and why
flexmail 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 15d 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.

Flexmail (via Apideck)
Access Flexmail through Apideck's CRM unified API — one of 21 CRM connectors that share the same method surface. Code you write here ports to Odoo, Salesforce, HubSpot and 17 other CRM connectors by changing a single serviceId string. Apideck handles auth, pagination, rate limiting, and retries so you don't write per-tenant Flexmail plumbing.
Quick facts
- Apideck serviceId:
flexmail - Unified API: CRM
- Auth type: basic
- Gotchas: page
- Flexmail docs: https://help.flexmail.eu
- Homepage: https://flexmail.be
At a glance
- Implementation difficulty: moderate — Personal Access Token Authentication - Each Consumer Creates Their Own Token in Flexmail
- Vendor partnership required: no — Nothing has to be registered with Flexmail to use this connector.
- Apideck-managed credentials: not available — Flexmail has no app to register or share; each consumer connects their own account.
- Account type required: Flexmail account on a plan that includes API access.
- Consumer access level: A Flexmail user who can create personal access tokens in Settings.
- Sandbox: available (signup) — Free 30-day trial account with Pro features, the API and up to 1,000 contacts.
- Costs: API calls are included in Flexmail plans, up to a monthly API request cap set by plan.
- Rate limits: 60 requests per minute for each account, client IP address and endpoint.
- Authentication: Account ID as the username and a personal access token as the password.
- Webhooks: No webhooks - poll for changes.
Important to know:
- Flexmail has no built-in company field. Company name is read and written through a custom field each consumer selects when connecting, separately for contacts and leads, so that custom field must exist in their Flexmail account first.

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.
