Create or revise native Codex .app.json mappings with stable ChatGPT developer-mode app ids, plugin linkage, and clear authentication ownership. Use when a plugin exposes an app-backed connector to Codex.

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.
Map only the apps the plugin truly exposes, without duplicating credentials or MCP transport data.
Inventory app names, canonical developer-mode ids, plugin linkage, and the user-visible authentication path.
Read ../../references/codex-artifact-contracts.md for the current .app.json schema.
Inspect kind-specific options, then generate:
python3 ../../scripts/create_codex_artifact.py app --help
python3 ../../scripts/create_codex_artifact.py app --output . --name example-app --description "Connector declarations for the example plugin" --app-id plugin_asdk_app_Example123
Replace example ids with source-backed ChatGPT developer-mode app ids and make the plugin manifest point to the actual .app.json.
Keep authentication outside the manifest; never add tokens, cookies, or user-specific state.
Validate:
python3 ../../scripts/check_codex_artifact.py app .app.json
Install in an isolated supported ChatGPT task and exercise the connected app when credentials are available.
