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 | $0.00072 | $0.02950 |
| Opus 5 | $0.00036 | $0.01475 |
| Sonnet 5 | $0.00014 | $0.00590 |
| Haiku 4.5 | $0.00007 | $0.00295 |
Grade A, and why
sinch-provisioning-api 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 2d 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 Provisioning API
Overview
Use this skill for Conversation API channel provisioning. Validated against Provisioning API v1.2.36. Prefer deterministic flows: confirm context, choose endpoint family, execute minimal calls, verify state.
Agent Instructions
Before generating code, gather from the user (skip any item already specified in the prompt or context):
- Project ID — confirm
projectId. - Microservice scope — each is a separate REST service: WhatsApp, RCS, KakaoTalk, Conversation, Webhooks, or Bundles. Endpoint families:
- WhatsApp account/senders/templates/flows/solutions:
/v1/projects/{projectId}/whatsapp/... - RCS:
/v1/projects/{projectId}/rcs/... - KakaoTalk:
/v1/projects/{projectId}/kakaotalk/... - Conversation (channel info):
/v1/projects/{projectId}/conversation/... - Webhooks:
/v1/projects/{projectId}/webhooks... - Bundles:
/v1/projects/{projectId}/bundles...
- WhatsApp account/senders/templates/flows/solutions:
- Language — any language, or curl. This API is REST-only; there is no SDK wrapper.
Product gotchas to apply unconditionally:
- Webhook
targetmust be unique per project. - Use
ALLfor webhook triggers when broad coverage is needed. - WhatsApp template language delete:
deleteSubmitteddefaults tofalse. - Some operations are asynchronous — register a provisioning webhook to receive completion notifications, or poll status endpoints. For bundles, subscribe to
BUNDLE_DONE. - All endpoints return a PAPI Error (
errorCode,message,resolution, optionaladditionalInformation) on failure. (Summary only — confirm exact names/encoding/enums against the authoritative Provisioning API Reference doc before implementing.) For429/5xx, retry with bounded backoff (max 3, exponential + jitter, max 10s delay). For4xx, useresolutionandadditionalInformationto guide correction. - Return resource IDs, resulting state, and next required action in the response to the user.
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.

sinch-provisioning-api is a skill published in the GitHub repository sinch/sinch-plugins (6 stars, last pushed 20d ago), licensed Apache-2.0. It adds 72 tokens to every session and 2,950 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 100% identical to sinch-provisioning-api, differing in 0 lines, and is treated as a copy.
