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.
Verify manifest structure and execute handlers as hostile boundaries with controlled inputs.
Read ../../references/codex-artifact-contracts.md and inventory all referenced handlers.
Run:
python3 ../../scripts/check_codex_artifact.py hook hooks/hooks.json
Check supported event names, matcher scope, command type, positive bounded timeouts, status messages, and duplicate lifecycle ownership.
Resolve PLUGIN_ROOT references and fail missing, non-portable, unquoted, or escaping paths.
Inspect handlers for secrets, unsafe shell interpolation, swallowed failures, unexpected network use, and writes outside intended roots.
Execute valid, malformed, failing, and timeout cases in a temporary directory without live credentials.
When available, compare discovery through hooks/list with the checked manifest.
Return PASS only when static and isolated execution checks succeed. Otherwise return FAIL with event, handler path, reproduction, and impact.
