Start here for the nddev-builder toolkit. Indexes the Codex artifact families and the creator, checker, reviewer, and workflow skill that owns each, points at the single reference for schemas and current (Beta, experimental, or under-development) surfaces, and routes the task to the right skill. Use first whenever building, checking, reviewing, or releasing a Codex artifact, or when unsure which builder skill applies.
A guided first run of the nddev-builder toolkit — from zero to a working, checked Codex artifact in ordered steps. Use when new to nddev-builder, onboarding, or unsure which builder skill to start with.
Create or revise a Codex marketplace catalog with valid plugin sources, categories, installation policy, and authentication policy. Use when publishing local or remote plugin collections.
Check a managed Codex requirements.toml layer for supported keys, permission-profile consistency, and a valid lower-layer default. Use before delivering managed /etc/codex or MDM requirements.
Create a managed Codex requirements.toml layer that constrains permission profiles and other admin policy. Use when authoring the /etc/codex or MDM-delivered managed requirements a lower config layer must satisfy.
Install and iterate on a Codex plugin locally in developer mode: the install, reinstall, and cachebuster test loop for a plugin under development, run against an isolated install and never live state. Use when running or iterating on a plugin, its skills, MCP, hooks, or bundled app locally.

Resolve every ../../scripts and ../../references path relative to this SKILL.md directory, never the caller working directory.
Validate catalog syntax, source integrity, and whether each entry can be installed as described.
Read ../../references/codex-artifact-contracts.md and identify the marketplace root.
Run:
python3 ../../scripts/check_codex_artifact.py marketplace .agents/plugins/marketplace.json
Check unique plugin ids, supported source forms, safe relative paths, categories, and required installation and authentication policy.
Resolve every local source and run the plugin checker on its complete plugin root.
Flag mutable or ambiguous remote provenance, embedded credentials, duplicate source-of-truth values, and entries that escape the catalog boundary.
In an isolated CODEX_HOME, exercise marketplace add/list and plugin discovery when those runtime methods are available.
Return PASS only when the catalog and reachable local plugins pass. Otherwise return FAIL with the marketplace entry, source path, and actionable reason.
