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 | $0.00022 | $0.00545 |
| Opus 5 | $0.00011 | $0.00272 |
| Sonnet 5 | $0.00004 | $0.00109 |
| Haiku 4.5 | $0.00002 | $0.00055 |
Grade A, and why
sinch-api-messages-send-carousel 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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Send RCS Carousel Message
Send a carousel of multiple rich cards to a recipient via the Sinch Conversation API. Recipient can swipe through cards. Supported primarily on RCS.
IMPORTANT: Execute this command directly. Do NOT generate script files. Perform the API call immediately.
Input
--to/-t: Recipient phone number (E.164) - required--cards/-c: JSON array of card objects, or path to JSON file. Each card: title, description (optional), image_url (optional), choices (optional array of {text, postback_data})
Arguments: $ARGUMENTS
Instructions
Execute these steps directly - do not write code or scripts:
-
If $ARGUMENTS empty: ask for recipient and cards (e.g. "Enter cards as JSON array or describe each card: title, description, image URL"). Otherwise parse.
-
Validate: --to (E.164), --cards (valid array of at least one card with title). Parse JSON or structured input into cards array.
-
Try MCP tool for carousel if available. On success display result and exit.
-
If MCP not available: get CONVERSATION_* env vars. If missing, report "Sinch API is not configured."
-
Build message.carousel_message with cards array: each card has title, description (optional), media_message (optional), choices (optional). Recipient via channel_identities (channel RCS).
-
POST https://{region}.conversation.api.sinch.com/v1/projects/{projectId}/messages:send with OAuth2, body: app_id, recipient, message.
-
On success: "✅ Carousel sent!" with message ID. Handle errors clearly.
-
Handle all errors gracefully.

Notes
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.
