Token cost

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.

Security

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 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:

  1. 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.

  2. Validate: --to (E.164), --cards (valid array of at least one card with title). Parse JSON or structured input into cards array.

  3. Try MCP tool for carousel if available. On success display result and exit.

  4. If MCP not available: get CONVERSATION_* env vars. If missing, report "Sinch API is not configured."

  5. Build message.carousel_message with cards array: each card has title, description (optional), media_message (optional), choices (optional). Recipient via channel_identities (channel RCS).

  6. POST https://{region}.conversation.api.sinch.com/v1/projects/{projectId}/messages:send with OAuth2, body: app_id, recipient, message.

  7. On success: "✅ Carousel sent!" with message ID. Handle errors clearly.

  8. Handle all errors gracefully.

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.
