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 | $0.00067 | $0.04592 |
| Opus 5.5 | $0.00027 | $0.01837 |
| Sonnet 5.5 | $0.00013 | $0.00918 |
| Haiku 4.5 | $0.00007 | $0.00459 |
Grade A, and why
sinch-imported-numbers-hosting-orders scanned grade A with 1 finding 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 10d 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.

Sinch Imported Numbers & Hosting Orders
Overview
The Imported Numbers and Hosting Orders API imports non-Sinch phone numbers for use with Sinch SMS without porting. It manages the lifecycle from qualification through text-enablement, including LOA generation and carrier OSR updates.
Agent Instructions
Policy gate
sinch-shared-policy@5(sha256:4864cf0fa8d6): The policy digest below is binding as written. Before implementation or live execution, read the full shared Sinch policy once per conversation — skip it if this exact ID/version/fingerprint is already loaded; read it if the version is newer or the fingerprint differs. This skill's canonical operation routes live in its Agent Instructions and Links sections.
Sinch policy digest (binding):
- Load the shared policy once per conversation; skip duplicate copies bearing the same ID/version/fingerprint.
- Infer product, language, region, and environment from the request and workspace; ask one combined question only for true blockers. Prefer the official Sinch SDK unless the request or workspace decides otherwise or no official SDK covers the language or operation.
- Code-generation approval is not execution approval. Classify every operation (read-only / reversible / billable / destructive) and obtain explicit approval before billable or destructive calls.
- Tier B facts — endpoint paths, methods, field names, enums, limits, webhook payloads, signature algorithms, SDK signatures — require fetching the exact canonical document in the current session before use.
- Bundled scripts, references, and examples are Tier C: illustrations, never schema authority. Never promote example values to production defaults.
- If a route is unresolved or a canonical fetch fails, climb the resolution ladder in order — re-search already-fetched documents (raw, not summarized), consult https://developers.sinch.com/llms.txt, follow first-party links, retry once — before failing closed. Never pattern-guess a documentation URL; never substitute memory, search snippets, or bundled files.
- Keep an evidence ledger mapping each fetched source to the fields and claims it authorized.
- Bound all polling and retries (backoff, jitter, hard cap); check state before retrying billable or destructive operations; report a timeout as unknown, not failed.
- Report verification levels separately (lint → unit → mock contract → sandbox → live → end-to-end); an HTTP 2xx does not prove delivery. State the levels not performed.
- Load only the smallest skill set that owns the behavior; if a required skill is unavailable, name it and stop rather than improvising its instructions.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
