OpenAI’s Plugin Ecosystem Connects ChatGPT, Codex

OpenAI is turning agent capabilities into an ecosystem play: packaging is becoming standardized, but discovery and trust will determine which integrations actually matter.

• –Shared distribution reduces the cost of supporting ChatGPT and Codex separately
• –Skills plus MCP servers let developers bundle both workflow guidance and executable tools
• –Search improves visibility beyond private or repo-scoped marketplaces
• –OpenAI’s review, privacy, and reliability requirements make publishing more credible but add friction
• –The biggest opportunity is turning specialized business workflows into reusable agent software
