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 the file in its intended scope and inspect the effective trust posture, not merely TOML syntax.
Identify user, repository, managed, or setup scope and read ../../references/codex-artifact-contracts.md.
Run:
python3 ../../scripts/check_codex_artifact.py config .codex/config.toml
Check supported keys, types, duplicate ownership, deprecated aliases, profile selectors, feature flags, paths, and MCP definitions.
Fail any active layer that mixes permission-profile settings with legacy sandbox settings.
Review approval, sandbox, filesystem, network, domain, and workspace settings against the stated trust boundary.
Reject secrets, user-specific runtime state, incomplete transports, and non-portable absolute paths.
Parse and start Codex with temporary HOME and CODEX_HOME; inspect effective config or diagnostics when supported.
Return PASS only when static consistency and available runtime parsing succeed. Otherwise return FAIL with table/key path, effective risk, and correction.
