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 | $0.00029 | $0.00532 |
| Opus 5 | $0.00015 | $0.00266 |
| Sonnet 5 | $0.00006 | $0.00106 |
| Haiku 4.5 | $0.00003 | $0.00053 |
Grade A, and why
sinch-api-10dlc-brands 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
10DLC Brand Registrations
List or create 10DLC (US A2P SMS) brand registrations using the Sinch 10DLC API. Brands must be registered before creating campaigns. Uses OAuth2. Base: https://us10dlc.api.sinch.com/v1.
IMPORTANT: Execute this command directly. Do NOT generate script files. Perform the API call immediately.
Input
--action/-a: list or create - optional, default list--display-name/-n: Brand display name (for create) - required if action=create--entity-type/-e: Entity type (PRIVATE, PUBLIC, etc.) - optional for create--format/-f: Output format (table or json) - optional
Arguments: $ARGUMENTS
Instructions
Execute these steps directly - do not write code or scripts:
-
If $ARGUMENTS empty: ask "List brands or create a new brand?" and get action, or for create get display name. Otherwise parse.
-
Validate: --action (list|create), for create require --display-name. Get CONVERSATION_PROJECT_ID, CONVERSATION_KEY_ID, CONVERSATION_KEY_SECRET. If missing, report "Sinch API is not configured."
-
If list: GET https://us10dlc.api.sinch.com/v1/projects/{projectId}/brandRegistrations with OAuth2. Display table or JSON.
-
If create: POST https://us10dlc.api.sinch.com/v1/projects/{projectId}/brandRegistrations with body (displayName, entityType if needed). Return brand ID. Handle 400 (validation).
-
"✅ Brands listed" or "✅ Brand created". Handle 401, 404. 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.
