# Agent Harness Router
Use this skill when the request spans an LLM control harness and its concrete
Codex or Claude runtime, or when the correct narrow workflow is unclear. Route
first; then load only the selected leaf skill.
## Routing
- Design, refactor, recover, or reconfigure the model/tool/state control plane,
including provider, tool, module, or loop hot swap: use
`agent-harness-engineering`.
- Benchmark, replay, diagnose, compare, or release-gate complete harness
behavior, including concurrent runtime generations and rollback: use
`agent-harness-evaluation`.
- Operate or diagnose Codex CLI: start with `codex-cli`, which routes exec and
review automation, deferred completion, task supervision, plugin/MCP
management, doctor/debug, rollout forensics, and app environments.
- Operate or diagnose Claude Code: start with `claude-code`, which routes print
automation, plugin/MCP management, doctor/debug, hooks/settings, agents,
worktrees, and sessions.
- Supply a password, passphrase, OTP, API token, device approval, or 1Password
credential to a task without returning the value to the agent: use
`credential-handoff`.
- Prove what launchd, systemd timer, cron, or Windows Task Scheduler actually
ran: use `scheduled-automation-runtime`.
For mixed requests, separate the claim boundaries. Use the vendor leaf for
exact commands, configuration, hooks, logs, or sessions; use harness
engineering for runtime-control design; use harness evaluation for empirical
