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 | $0.00052 | $0.00497 |
| Opus 5.5 | $0.00021 | $0.00199 |
| Sonnet 5.5 | $0.00010 | $0.00099 |
| Haiku 4.5 | $0.00005 | $0.00050 |
Grade A, and why
favcrm-agentic-registration 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 1mo 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.
What it actually says
FavCRM Agentic Registration
Use this skill when a new user wants to sign up for FavCRM without leaving an MCP client. The real product flow is the no-auth MCP tool pair register_organisation_request -> register_organisation_verify.
Operating Rules
- Primary MCP path is
register_organisation_requestfollowed byregister_organisation_verify. - When operating through a shell, the
favcrmCLI supports the same no-auth flow withfavcrm signup requestandfavcrm signup verify. - Treat
/v6/dev/signupand/v6/dev/verifyas REST sandbox fallback/docs only. - Never ask the user to paste the API key into a repo, prompt history file, shared config, or source code.
- If the user already has a FavCRM account, tell them to sign in and create an MCP key from portal settings.
Required Inputs
email: owner email that receives the 6-digit code.organisationName: business or brand name.
Optional Inputs
industry: one ofbeauty,fitness,tutoring,retail,hospitality,services,other.country: ISO 3166-1 alpha-2 country code, such asHK,US,GB.timezone: IANA timezone, such asAsia/Hong_Kong.
Standard Flow
- Collect required inputs and optional fields if known.
- Call
register_organisation_request. - Tell the user to check the masked email for the 6-digit code.
- When the user provides the code, call
register_organisation_verifywithrequestIdandcode. - Return the
loginUrl, workspace IDs if useful, and secure key handling guidance. - Tell the user to set the API key as the MCP Bearer token or environment variable for future calls. If using the CLI,
favcrm signup verifysaves the key by default unless--no-saveis used.

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.
