What is Jev Workflows for Codex?

An open-source Codex plugin for consulting TypeSafe Jev about tools, models, tasks, skills, context, strategies, and custom decisions. It also diagnoses failed commands and checks completion claims against evidence.

How do I install the plugin?

Run codex plugin marketplace add integrate-your-mind/jev-codex-plugin, then codex plugin add jev-workflows@jev-workflows, start a fresh Codex task, and trust the installed hooks when prompted. It requires Node.js 22+ and TYPESAFE_API_KEY in the host environment.

Which MCP tools does the plugin provide?

Eight tools: classify_decision, classify_failure, check_completion, evaluate_decisions, update_task_context, record_decision_outcome, jev_status, and configure_automation.

Can I use the skills without MCP?

Yes. Three standalone skills ship as ZIPs with instructions and a prebuilt Node.js CLI; extract each into a supported skill directory and keep the whole folder together. Use the full plugin when you want automatic lifecycle hooks.

Is it listed in the official OpenAI plugin directory?

No. The catalog contribution is prepared in a public fork, but OpenAI restricts upstream PR creation to repository collaborators and no official store listing is live; the separate directory draft still needs local-plugin compatibility review.

Does the plugin impose quotas or run automatically?

There is no plugin-imposed daily, byte, or session quota by default; TypeSafe API charges and rate limits apply. Fresh installs keep automation disabled until you ask Codex to enable Jev automation.

What happens when Jev abstains or is unavailable?

The standalone CLI defaults to a local preview, and authorized evaluation requires --evaluate plus your key in the environment. An abstention or unavailable result does not stop ordinary work.

Watch out

Copy reviewed against the repository README on 2026-10-15; it was truncated in the digest. The README says no official store listing is live and the directory draft still needs local-plugin compatibility review. TypeSafe's API charges and rate limits apply, and automation stays disabled on fresh installs until you enable it.

MCP tool routing: Jev in front of the tool call

Oct 16, 2026

Tool menus can outgrow the context that reads them. The catalog's Jev-based routers and gates narrow the list: benchmarked tool search, per-tool scoring, fail-closed approvals, and WebMCP in the browser.

Approval policies for coding agents: hooks, guards, and gateways

How the Jev guard family turns coding-agent permissions into auto-approve, deny, or ask: hooks that enforce, guards that fail safe, and gateways that gate generation.
