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 one focused Codex skill that is easy to trigger, cheap to load, and deterministic where automation helps.
Identify the skill's single job, trigger phrases, output, and repository or user scope.
Prefer the built-in $skill-creator workflow for discovery and first-party scaffolding.
Read ../../references/codex-artifact-contracts.md before deciding paths or metadata.
If a scaffold is still needed, inspect options and run:
python3 ../../scripts/create_codex_artifact.py skill --help
python3 ../../scripts/create_codex_artifact.py skill --output .agents/skills --name example-skill --description "Create repeatable repository workflows"
Replace generated examples with concise instructions. Keep exact schemas or long guidance in references/, deterministic work in scripts/, and output assets in assets/.
Add agents/openai.yaml with a useful display name, a 25-64 character summary, and a default prompt that explicitly names the skill.
Do not create slash-command files; Codex workflows are skills.
Validate the finished directory:
python3 ../../scripts/check_codex_artifact.py skill .agents/skills/example-skill
Exercise at least one realistic explicit invocation and one description-based routing case. Report files changed and checks run.
