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-location 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 8d 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.

Send Location Message

Send a location (latitude, longitude, optional label) to a recipient via the Sinch Conversation API. Supported on RCS, WhatsApp, and other channels that support location sharing.

IMPORTANT: Execute this command directly. Do NOT generate script files. Perform the API call immediately.

Input

  • --to / -t: Recipient phone number (E.164) - required
  • --lat / -y: Latitude (decimal) - required
  • --lon / -x: Longitude (decimal) - required
  • --label / -l: Optional label for the location (e.g. "Store downtown")
  • --channel / -c: Channel (RCS, WHATSAPP) - optional

Arguments: $ARGUMENTS

Instructions

Execute these steps directly - do not write code or scripts:

  1. If $ARGUMENTS empty: ask for recipient, latitude, longitude, and optional label. Otherwise parse.

  2. Validate: --to (E.164), --lat (valid number -90 to 90), --lon (valid number -180 to 180). Optional: --label, --channel.

  3. Try MCP tool mcp__sinch__send-location-message if available with recipient, lat, lon, label, channel. 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.location_message with latitude, longitude, and optional title (label). Recipient via channel_identities.

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

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

  8. Handle all errors gracefully.

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.
