Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.
How agent discovery & health will work →About
Use Codex for coding tasks when the Coding Agent Harness context selects it. Follow that context's command template and run it through Nakama's bash tool with codingAgent: true, cwd set to the target project, and a task-appropriate timeoutMs.
Prerequisites
- Install Codex on the Nakama host if needed:
npm install -g @openai/codex. - Authenticate with
codex loginor configureOPENAI_API_KEY. A missing API key does not imply that CLI login is missing. - Check
codex --versionandcodex login statuswhen installation or auth is uncertain.
One-shot coding
codex exec is non-interactive and works with Nakama's pipe-based bash tool. Do not request a PTY or use an interactive codex session there.
codex --ask-for-approval never exec --skip-git-repo-check --sandbox workspace-write --color never 'Make the requested change, run targeted checks, and summarize the result.'--ask-for-approval is a top-level option and must come before exec. --skip-git-repo-check permits scratch work outside a git repository; it does not replace setting cwd to the right project for repo changes. Put the task prompt in one shell argument and quote it safely.
If workspace sandbox setup fails on the host, report the error. Use --sandbox danger-full-access only when the operator has authorized running Codex with the host process's full filesystem access.
Reviews
From the target repository, use codex review --base origin/main for branch changes or codex review --uncommitted for local edits. Keep review work read-only unless the user asked for fixes.
After the run
Check the bash exit code and timeout result. Verify changed files and targeted tests before reporting success. For implementation tasks, follow the coding-agent skill's branch, commit, push, and PR instructions unless the user requested local-only work.
