### Agent runtime selection
`agent.command` controls which Pi-compatible CLI PI WEB checks in doctor/status/update flows. It defaults to `pi`; set it to `omp` when this machine should use Oh My Pi.
`agent.command` controls which Pi-compatible CLI PI WEB checks in doctor/status/update flows. It defaults to `pi`. Set it only when diagnostics and package-managed update checks should target another compatible command; the embedded session runtime still uses PI WEB's SDK integration.
`agent.dir` controls which compatible agent state directory PI WEB reads for auth providers, model settings, settings, and session metadata. It defaults to the selected agent's conventional directory (`~/.pi/agent` for `pi`, `~/.omp/agent` for `omp`).
`agent.dir` controls which compatible agent state directory PI WEB reads for auth providers, model settings, settings, and session metadata. It defaults to `~/.pi/agent`. Set it to another Pi-compatible state directory when you want an isolated profile or an alternate compatible agent's data.
```json
{
"agent": {
"command": "omp",
"dir": "~/.omp/agent"
"command": "pi",
"dir": "~/agent-profiles/research"
}
}
```
Environment variables take precedence over the config file. `PI_WEB_AGENT_COMMAND` selects the command, `PI_WEB_AGENT_DIR` sets the state directory for any command, and command-specific variables such as `OMP_CODING_AGENT_DIR` are honored when the selected command is `omp`.
For example, an Oh My Pi profile can set `agent.command` to `omp` and `agent.dir` to `~/.omp/agent`.
Session directory overrides are environment-only. Set `PI_WEB_AGENT_SESSION_DIR` or the selected command's session variable (for example `OMP_CODING_AGENT_SESSION_DIR`) when you need to override session storage separately from `agent.dir`.
Environment variables take precedence over the config file. `PI_WEB_AGENT_COMMAND` selects the command, `PI_WEB_AGENT_DIR` sets the state directory for any command, and `PI_WEB_AGENT_SESSION_DIR` overrides session storage separately from `agent.dir`. Existing Pi Coding Agent env names (`PI_CODING_AGENT_DIR` and `PI_CODING_AGENT_SESSION_DIR`) remain supported for compatibility.
Restart the session daemon after changing agent settings. The web/API process can display the new config immediately, but active session runtime ownership is intentionally long-lived.
Session directory overrides are environment-only; use `PI_WEB_AGENT_SESSION_DIR` unless you need the legacy Pi-compatible `PI_CODING_AGENT_SESSION_DIR` name.
Restart the session daemon after changing agent settings. The web/API process can display the new config immediately, and status/plugin discovery may re-read it on later requests, but active session runtime ownership is intentionally long-lived.
