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-fax-list 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.

What it actually says

List Faxes

List faxes for your project using the Sinch Fax API. Supports pagination. Uses OAuth2.

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

Input

  • --format / -f: Output format (table or json) - optional, default table
  • --page-size / -n: Number of results - optional

Arguments: $ARGUMENTS

Instructions

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

  1. If $ARGUMENTS empty: use defaults (table format). Otherwise parse.

  2. Get CONVERSATION_* or FAX_* env vars. GET https://fax.api.sinch.com/v3/projects/{projectId}/faxes with OAuth2. If missing, report "Sinch API is not configured."

  3. Format response: table (id, to, status, createdAt, etc.) or JSON. Display "✅ Faxes listed" with count.

  4. Handle 401, 404. Handle all errors gracefully.

/sinch-api-fax-list --format=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.
