.agents/skills/vendor-listing/SKILL.md

vendor-listing is a skill for Claude Code, Codex from superdesigndev/treg. It costs 117 tokens per session (4,689 once invoked), scanned A, original, no licence file.

A workflow for adding a vendor’s API to the treg catalogue and reviewing its listing request.

In plain words
What is it for?
Use it when a vendor asks to be listed, sends API details, or opens a listing issue or pull request.
Why use it?
It gives coding agents a defined path for checking eligibility, preparing the listing, and testing it before it goes live.

Skill for Claude CodeCodex

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is superdesigndev/treg's own configuration. It tells Claude Code and Codex how to work on treg itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything treg configures →

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

vendor-listing scanned grade A with 0 findings 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 3d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The source is not reproduced here

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 ships with it

Changes

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.
