Codex reads AGENTS.md from the project root (and from parent folders), and skills from .agents/skills/<name>/SKILL.md. That makes it the simplest agent to equip: most loadouts install for Codex with no adapter at all.
MCP servers are the exception. Codex keeps them in ~/.codex/config.toml as TOML rather than in a project JSON file, so loadouts with an MCP config give you a manual step with the exact server to add.

Manual step (see below)
9 native, 2 with one manual step
discord.js v14 rules and an add-a-slash-command skill for building a Discord bot that registers commands properly and never leaks its token.
GDScript conventions, jam-scope discipline and a ship-to-itch.io skill so your agent helps you finish a Godot 4 game in 48 hours.
Rules and an add-a-tool skill for building a Model Context Protocol server in TypeScript that agents can actually use well — clear tools, safe inputs, no stdout noise.
Rules, an RLS audit skill and a read-only Supabase MCP config for vibe-coding a Next.js App Router SaaS without leaking your database.
A launch-check skill and always-on security rules that catch leaked keys, open databases and missing auth before your vibe-coded app goes live.
A stack-agnostic working style for coding agents — plan first, small diffs, never delete tests to go green — plus handoff notes and up-to-date docs via MCP.
Astro conventions for fast, zero-JS-by-default sites with content collections, plus a skill for deploying to Cloudflare Pages with headers and redirects.
Manifest V3 rules for service workers, messaging and minimal permissions, plus a skill that gets your extension through Chrome Web Store review.
Rules for reproducible, single-file Python data scripts with uv and inline dependencies, plus a skill that sanity-checks a dataset before anyone trusts the numbers.
Luau conventions for Rojo projects with a server-authoritative mindset, plus a skill that reviews every RemoteEvent for exploits before you publish.
Unity C# conventions that respect the editor, .meta files and serialisation, plus a skill for scripted web builds ready for itch.io.
Next.js + Supabase SaaS, Vibe-coding guard rails have an MCP config that Codex CLI needs you to add by hand; the loadout page shows exactly what to add.
Connect the read-only Agent Loadout MCP server and ask Codex CLI for "a loadout for my Godot jam". It can search, read files and get install paths for Codex CLI without you copying anything. Set-up for every agent.
codex mcp add agent-loadout --url https://loadout.jnw-it.com/mcp
Codex CLI reads AGENTS.md. Agent Loadout keeps the shared rules in AGENTS.md so one set of rules works across agents.
Each skill is a folder with a SKILL.md file. For Codex CLI they go in .agents/skills/<skill-name>/SKILL.md, relative to the project root.
Codex reads MCP servers from ~/.codex/config.toml (TOML, not JSON). Add each server with `codex mcp add` or copy the URL into an [mcp_servers.<name>] table.
Add the read-only server at https://loadout.jnw-it.com/mcp: codex mcp add agent-loadout --url https://loadout.jnw-it.com/mcp. It needs no sign-in, and lets Codex CLI search loadouts and fetch exact install steps itself.
