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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Writing a provider skill 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 matter, what the parameters really are, and where the API lies to you.* The third part is the one MCP can't give you, and it's where nearly all the value is. ## The rule that decides what goes in > **Document what produces a wrong answer without producing an error.** Ranked by value to an agent: | Class | Why it matters | Example | |---|---|---| | **Silent wrong answers** | Agent reports confidently false results. Unrecoverable alone. | GA4: incompatible dimension+metric returns `"0"` per row, not an error — reads as "no revenue" | | **Wrong-shaped errors** | Error doesn't describe the real cause, so retries go sideways | GA4: bad path returns a Google **HTML 404 page**, not JSON — a JSON parse throws something unrelated | | **Unguessable identifiers** | Agent invents an ID and gets 403/404 forever | GA4 needs `properties/123456789`; GSC needs `sc-domain:x.com` vs `https://x.com/` | …

How to install
mdr add superdesigndev/treg/write-provider-skill@sha256:3ad97313e485d030The line at the top of this page pins the label git:20260928.ce916f2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
