write-provider-skill

write-provider-skill is a skill for Claude Code, Codex from superdesigndev/treg. It costs 73 tokens per session (1,546 once invoked), scanned A, original, no licence file.

A guide for building a provider skill: a map of an online platform's API endpoints and common mistakes when using them through treg's proxy. An API is the interface that lets software work with a platform.

In plain words
What is it for?
Adding, checking, or extending treg provider skills for services such as Google Ads, LinkedIn, Meta Ads, TikTok, X, Instagram, and Search Console.
Why use it?
It helps an agent use a connected platform correctly instead of guessing how its API works or repeating known errors.

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

write-provider-skill 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 5d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
