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 | $0.00018 | $0.00510 |
| Opus 5 | $0.00009 | $0.00255 |
| Sonnet 5 | $0.00004 | $0.00102 |
| Haiku 4.5 | $0.00002 | $0.00051 |
Grade A, and why
sinch-email-mailjet-send 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 9d 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

If $ARGUMENTS empty: ask for from, to, subject, and text or html. Otherwise parse.
-
Validate: --from, --to, --subject; at least one of --text or --html. Get MJ_APIKEY_PUBLIC and MJ_APIKEY_PRIVATE from env. If missing, report "Mailjet is not configured. Set MJ_APIKEY_PUBLIC and MJ_APIKEY_PRIVATE."
-
Request body: Messages array with one object: From (Email, Name), To ([{Email, Name}]), Subject, TextPart, HTMLPart. POST https://api.mailjet.com/v3.1/send with Basic Auth (MJ_APIKEY_PUBLIC:MJ_APIKEY_PRIVATE), Content-Type application/json.

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.
