## Grok provider (xAI)

Agents whose provider is `GROK` run xAI's official `grok` CLI. Auth is the host SuperGrok subscription (mounted `~/.grok`), not a metered API key.

| Variable | Default | Description |
|----------|---------|-------------|
| `ROBOCO_HOST_GROK_DIR` | `~/.grok` | Host dir holding `auth.json`, mounted into Grok agents; the orchestrator auto-refreshes the ~6h token in place. Set up once with `grok login`. |

| `ROBOCO_GROK_IDLE_KILL_SECONDS` | `900` | Kill + evict a Grok container that has been ACTIVE-yet-idle (no gateway verb) this long |
| `ROBOCO_GROK_MAX_COST_USD` | `0.0` | Per-agent Grok cost ceiling (USD); `0` disables |

## Self-Healing CI loop

RoboCo watching its own repo's CI. All default-off / dormant.

| Variable | Default | Description |
|----------|---------|-------------|
| `ROBOCO_SELF_HEAL_ENABLED` | `false` | Master switch (detect + notify the CEO); off = the loop never runs and no CI is fetched |
| `ROBOCO_SELF_HEAL_ORIGINATE_ENABLED` | `false` | Second opt-in: also open a PENDING fix task on a regression — CEO-gated, never auto-started/merged/deployed |
| `ROBOCO_SELF_HEAL_PROJECT_SLUG` | (empty) | The registered project that IS RoboCo itself — the only repo it watches and fixes; empty = no-op |
| `ROBOCO_SELF_HEAL_CI_WORKFLOW` | (empty) | GitHub Actions workflow to scope the CI signal to (e.g. `ci.yml`); empty = latest across all workflows |
| `ROBOCO_SELF_HEAL_INTERVAL_SECONDS` | `1800` | Seconds between assessment passes |
| `ROBOCO_SELF_HEAL_MAX_OPEN_TASKS` | `3` | Rolling cap on concurrently-open self-heal tasks |
| `ROBOCO_SELF_HEAL_MAX_PER_CYCLE` | `1` | Max fix tasks originated per cycle |

## Security

| Variable | Default | Description |
|----------|---------|-------------|
| `ROBOCO_ENCRYPTION_KEY` | (required) | Fernet key that encrypts secrets at rest (e.g. per-project git tokens). Generate with `Fernet.generate_key()`. |
| `ROBOCO_AGENT_AUTH_SECRET` | (required) | HMAC secret the orchestrator signs each agent's `X-Agent-Token` with. |
| `ROBOCO_AGENT_AUTH_REQUIRED` | `false` | When `true`, every request must carry a valid agent token (secure mode). |
| `ROBOCO_PANEL_AGENT_TOKEN` | (unset) | The control panel's CEO token, injected by nginx in secure mode. Get it with `make panel-token`. |
