market AGENTS.md

Repository instructions for a public marketplace of coding-agent add-ons. They define rules for keeping contributions reusable, customer-neutral, safe to publish, and clear about outside software dependencies.

In plain words
What is it for?
Use them when writing marketplace descriptions, examples, filenames, metadata, tests, screenshots, or release materials for a public add-on.
Why use it?
They reduce the risk of exposing confidential identities or tokens and help users understand when an add-on depends on separately licensed or hosted software.

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

market AGENTS.md 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 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.

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.

How it starts

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

This repository is a public marketplace. Every contribution must be reusable, customer-neutral, and safe to index publicly.

Public information boundary

  • Never put a tenant, customer, prospect, partner, or other confidential identity in tracked files, paths, filenames, Agent or Skill IDs, frontmatter, descriptions, examples, fixtures, memories, generated artifacts, or screenshots.
  • Apply the same rule to Git metadata and collaboration text: branch names, commit subjects and bodies, PR or issue titles and bodies, comments, and review replies.
  • Describe reusable capabilities with domain-neutral roles and entities. Put customer-specific prompts, facts, mappings, examples, data, and deployment settings only in private AgentFS homes, private repositories, or private runtime configuration.
  • Do not add a real confidential token to a denylist, test fixture, documentation, or example. A literal denylist in a public repository creates a second leak.

External dependency disclosure

  • A Skill or Agent that relies on separately licensed, purchased, hosted, or deployed third-party software must disclose that dependency in its discovery description, compatibility field, localized marketplace text, and execution instructions.
  • Distinguish an included connector or adapter Tool from the external product it accesses. Never imply that registering a Tool bundles, licenses, installs, pays for, or operates the third-party product.
  • State the operator prerequisites, applicable licensing or usage terms, separate costs when relevant, connection readiness checks, and safe degraded behavior. If the dependency is unavailable, stop before the external call and never fabricate a successful result.

Required pre-publication check

Before committing or opening/updating a PR:

  1. Obtain the sensitive tokens through a private channel and keep them outside the repository.
  2. Scan the complete working tree, including hidden files while excluding .git.
  3. Scan new path names, branch names, commit subjects and bodies, and the proposed PR/issue/review text.
  4. Review examples semantically: changing a proper noun is insufficient when an example still exposes a customer-specific organization shape or private fact.
  5. Run the repository validation and translation-freshness checks documented in README.md.

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.
