What it does

Write Provider Skill is an agent skill from superdesigndev/treg. Build a treg provider skill — the endpoint map + mistake map that lets an agent do real work on a platform API through treg's proxy. Use when adding a skill for a connected provider (Google Ads, LinkedIn, Meta Ads, TikTok, X, Instagram, Search Console), or when an existing provider skill needs verifying or extending.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Marketing & SEO, covering Paid advertising. It works with Google Ads, Google Search Console, Instagram and LinkedIn. The repository describes itself as: OpenRouter for agent tools. Join community here: https://discord.gg/6mQYYfFMAn.

When your agent uses it

  • Adding a skill for a connected provider (Google Ads
  • Search Console)
  • An existing provider skill needs verifying

Example prompts

  • “/write-provider-skill”

Requirements

  • Node.js

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Get an explicit designated target from the human (throwaway account, sandbox ad account)
  2. Get explicit per-provider go-ahead
  3. If neither exists, mark the endpoint ⚠️ unverified and document it from the API reference

What it can do on your machine

Read from SKILL.md and the folder at commit e609803. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • sqlite3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • x.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Write Provider Skill loads about 1.7k tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 741 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~85
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 741 words (~1,693 tokens).

“A provider skill is an MCP server made of documentation. An MCP server gives a model a tool list and typed parameters. We can't ship a server per platform, so the skill carries the same payload as prose: which endpoints…”
