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.
Create the smallest configuration layer that owns the requested behavior and composes cleanly with higher-precedence scopes.
Identify scope, precedence, trust boundary, portability needs, and the exact settings being changed.
Read ../../references/codex-artifact-contracts.md for supported keys and current deprecations.
Inspect options and generate a baseline:
python3 ../../scripts/create_codex_artifact.py config --help
python3 ../../scripts/create_codex_artifact.py config --output .codex --name config --description "Repository Codex configuration"
Add only source-backed keys. Keep user credentials and machine-local state outside the file.
Do not mix permission-profile settings with legacy sandbox settings in one active layer. Avoid deprecated aliases and legacy profile selectors.
Keep MCP runtime definitions complete and use environment references for secrets.
Validate:
python3 ../../scripts/check_codex_artifact.py config .codex/config.toml
Run Codex with temporary HOME and CODEX_HOME to confirm parsing and effective behavior without mutating live state.
