Instructions file for Claude CodeCodexOpenCode

Written for Claude Code and Codex and OpenCode: Claude Code plugin machinery, but also the file is AGENTS.md. Also seen: mentions AGENTS.md; mentions Codex.

This is Nunley-Media-Group/nmg-plugins's own configuration. It tells Claude Code, Codex and OpenCode how to work on nmg-plugins 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 nmg-plugins 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

nmg-plugins 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 8d 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.

Project Overview

Plugin marketplace repository for Nunley Media Group. Each listed plugin lives in its own GitHub repository and is referenced from host-specific catalogs. No plugins are currently listed.

Repository Structure

.agents/plugins/marketplace.json  — Codex marketplace index (Git-backed plugin entries)
.omp-plugin/marketplace.json      — Preferred Oh My Pi marketplace catalog
.claude-plugin/marketplace.json   — Claude-compatible index consumed by Pi and as OMP fallback
README.md                         — Public docs: how to add the marketplace, plugin pointers

Maintaining the Marketplace

When adding or removing a plugin:

  1. Edit .agents/plugins/marketplace.json:
    • Add a new entry to the plugins array, or remove an existing one
    • For a plugin repo whose .codex-plugin/plugin.json lives at the repo root, use: {"source": {"source": "url", "url": "https://github.com/owner/name.git", "ref": "main"}}
    • If the plugin lives in a subdirectory, use source: "git-subdir" with a path
    • Include policy.installation, policy.authentication, and category on every entry
  2. Keep the matching entries in .omp-plugin/marketplace.json and .claude-plugin/marketplace.json synchronized for Oh My Pi and Pi compatibility.
  3. Run node scripts/validate-marketplace.mjs.
  4. Update README.md to list the plugin and its source repo.
  5. Open a PR.

Version bumps happen entirely in each plugin's own repo; this marketplace file only changes when a plugin is added, removed, renamed, or repointed to a different ref or URL.

Plugin development (skills, agents, tests, releases) happens entirely in each plugin's own repo. This repo is intentionally thin — it only points users at the plugins that make up the marketplace.

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.
