- Treat the OpenAI Codex docs as the source of truth for plugin packaging, skill metadata, and
AGENTS.mdconventions. - Before calling the local install flow complete, validate marketplace registration with
CODEX_HOME=$(mktemp -d) codex plugin marketplace add .. - Keep install-facing copy accurate. Do not leave placeholder commands in
README.mdor manifest prompts. - Keep each skill focused on one job. When changing a skill name or trigger description, update
SKILL.md,agents/openai.yaml,README.md, and plugin prompts together. - Prefer live Massive MCP and official Massive docs for current endpoint details. Do not document guessed endpoints, parameters, or plan access rules.
