See setup guidance ↓Original source ↗ SOURCE REVIEW Reviewed 2026-09-21 Evidence 6 linked sources Publisher OpenAI Licence Proprietary (declared in plugin manifest) ↗ Revision 1dc195897af4 Read what was—and wasn’t—checked ↓ “Use when an OpenAI API request fails and Codex needs to classify the likely cause, explain the next step, and route to the right follow-up.” OpenAI · upstream description ↗ Our analysis follows below. 01 / THE REASONING ## Why this made the selection. - Distinguishes exhausted quota from ordinary rate limiting even when the HTTP status is the same. - Avoids diagnosing an authentication or model-access problem before the request has reached the API. ### A good fit for - Understanding an OpenAI SDK request failure - Choosing the next diagnostic step without rotating keys unnecessarily ### Weigh up before choosing - It relies on companion documentation and credential skills; it does not provision or rotate keys itself. - Its environment-escalation recipe is host-specific and cannot override the host’s permission policy. - Static example model suggestions can age and should not be treated as a current model ranking. 02 / THE REVIEW RECORD ## What we actually inspected. Source review has boundaries. A clear record is more useful than a “safe” badge. ### Material inspected - plugins/openai-developers/skills/openai-api-troubleshooting/SKILL.md - plugins/openai-developers/skills/openai-api-troubleshooting/references/evals.md - plugins/openai-developers/.codex-plugin/plugin.json - plugins/openai-developers/README.md ### Our findings - The routing uses specific error codes/messages before broader heuristics. - The included evaluation cases cover triggering, quota-versus-rate-limit distinctions and correct handoffs. - Credential creation remains in the companion flow and billing is distinguished from a ChatGPT subscription. ### Not established by this review - Source inspection only; no skill installation or workflow execution was performed. The review applies to the material and revision named here. A newer upstream release can change its behavior. 03 / PUT IT TO WORK ## Add a skill to your workflow. Upstream setup instructions ↗ - Use the complete openai-developers Codex plugin through its supported distribution and setup instructions. - Retain plugin-level references and companion skills; this is not a standalone SKILL.md installation. - Confirm plugin availability and any required connectors in the Codex host before invoking the workflow. ### Before you start - A Codex host with access to this plugin and its applicable service terms - A redacted actual error response or transport failure - Current docs access for account-specific remediation ### Compatibility Codex OpenAI Developers plugin · Applications making OpenAI API requests ### Inspect redacted request errors and relevant configuration - Inspect redacted request errors and relevant configuration - Potentially retry the actual request within authorized network permissions - Route credential changes to the separate confirmed setup flow ### Cost model The proprietary plugin follows Codex terms; request retries can consume API usage and ChatGPT subscriptions do not establish API credit. 04 / FOLLOW THE EVIDENCE ## The source trail. Our notes are separate from the original resource. Check upstream before adopting a new version. - Skill definition at reviewed revision ↗ Checked 2026-09-21 https://github.com/openai/plugins/blob/1dc195897af4161d039b80d8471ec0a10c9bbc89/plugins/openai-developers/skills/openai-api-troubleshooting/SKILL.md Supports: summary, upstreamDescription, whySelected, bestFor, limitations, review, compatibility, access - Reviewed reference or helper: references/evals.md ↗ Checked 2026-09-21 https://github.com/openai/plugins/blob/1dc195897af4161d039b80d8471ec0a10c9bbc89/plugins/openai-developers/skills/openai-api-troubleshooting/references/evals.md Supports: review, limitations, access - Upstream license or licensing declaration ↗ Checked 2026-09-21 https://github.com/openai/plugins/blob/1dc195897af4161d039b80d8471ec0a10c9bbc89/plugins/openai-developers/.codex-plugin/plugin.json Supports: license - Publisher installation and project documentation ↗ Checked 2026-09-21 https://github.com/openai/plugins/blob/1dc195897af4161d039b80d8471ec0a10c9bbc89/README.md Supports: install, compatibility, access - Skills installer source formats and selective installation ↗ Checked 2026-09-21 https://github.com/vercel-labs/skills/blob/7407f3893ad4dceab546ac002c3ef806e4000c73/README.md Supports: install - Complete plugin setup and operational boundaries ↗ Checked 2026-09-21 https://github.com/openai/plugins/blob/1dc195897af4161d039b80d8471ec0a10c9bbc89/plugins/openai-developers/README.md Supports: install, compatibility, access, review KEEP COMPARING ## Other approaches to consider.
