openclaw crestodian

Crestodian is OpenClaw’s local setup, repair, and configuration helper. It stays reachable when the normal agent path is broken: it can run when openclaw.json is missing or invalid, the Gateway is down, plugin command registration is unavailable, or no agent is configured yet.

​
When it starts

Running openclaw with no subcommand routes based on config state:
  • Config missing, or exists with no authored settings (empty, or only $schema/meta keys): starts classic onboarding.
  • Config exists but fails validation: starts Crestodian.
  • Config exists and is valid: opens the normal agent TUI (against a reachable configured Gateway, or locally if none is reachable). Use /crestodian inside the TUI, or run openclaw crestodian directly, to reach Crestodian.
Running openclaw crestodian always starts Crestodian explicitly, regardless of config state. openclaw --help and openclaw --version keep their normal fast paths. Noninteractive bare openclaw (no TTY) exits with a short message instead of printing root help: it points to non-interactive onboarding on a fresh install, to openclaw crestodian --message "status" when config is invalid, or to openclaw agent --local ... when config is valid. openclaw onboard --modern starts Crestodian as the modern onboarding preview. Plain openclaw onboard keeps classic onboarding.

​
What Crestodian shows

Interactive Crestodian opens the same TUI shell as openclaw tui, with a Crestodian chat backend. The startup greeting covers:
  • config validity and the default agent
  • the model or deterministic planner path Crestodian is using
  • Gateway reachability from the first startup probe
  • the next recommended debug action
It does not dump secrets or load plugin CLI commands just to start. Use status for the detailed inventory: config path, docs/source paths, local CLI probes, key/token presence, agents, model, and Gateway details. Crestodian uses the same reference discovery as regular agents: in a Git checkout it points at local docs/ and the source tree; in an npm install it uses bundled docs and links to https://github.com/openclaw/openclaw, with guidance to check source when docs are not enough.

​
Operations and approval

Crestodian uses typed operations instead of editing config ad hoc. Read-only, run immediately: show overview, list agents, list installed plugins, search ClawHub plugins, show model/backend status, run status/health checks, check Gateway reachability, run doctor without interactive fixes, validate config, show the audit-log path. Starting the guided channel setup (connect telegram) also runs immediately — the wizard itself collects explicit answers and commits only at the end. Persistent, require conversational approval (or --yes for a direct command): write config, config set, config set-ref, setup/onboarding bootstrap, change the default model, start/stop/restart the Gateway, create agents, install or uninstall plugins, run doctor repairs that rewrite config or state. Approval is given in your own words: unambiguous replies (“yes”, “sure”, “go ahead”, “not now”) resolve from a closed deterministic list, and anything else is judged by a separate host-run model call that sees only your message and the pending proposal — never by the conversation model itself, which cannot self-approve. Ambiguous replies keep the proposal pending and the conversation asks again. When no model is usable, only the closed deterministic list applies. Applied writes are recorded in ~/.openclaw/audit/crestodian.jsonl. Discovery is not audited; only applied operations and writes are. Channel setup can run as a hosted conversation when the host supports masked input. The local Crestodian TUI does not accept sensitive wizard answers; instead it directs you to openclaw channels add --channel <channel>, whose interactive prompts mask credentials.

​
Setup bootstrap

setup is the chat-first onboarding bootstrap. It writes only through typed config operations and asks for approval first. 
setup
setup workspace ~/Projects/work
setup workspace ~/Projects/work model openai/gpt-5.5
When no model is configured, setup picks the first usable backend in this order and tells you what it chose:
  1. Existing explicit model, if already configured.
  2. OPENAI_API_KEY -> openai/gpt-5.5
  3. ANTHROPIC_API_KEY -> anthropic/claude-opus-4-8
  4. Claude Code CLI -> claude-cli/claude-opus-4-8
  5. Codex -> openai/gpt-5.5 through the Codex app-server harness
  6. Gemini CLI -> google-gemini-cli/gemini-3.1-pro-preview
If none are available, setup still writes the default workspace and leaves the model unset. Install or log into Codex/Claude Code/Gemini CLI, or expose OPENAI_API_KEY/ANTHROPIC_API_KEY, then run setup again. The macOS app drives the same ladder through the crestodian.setup.detect and crestodian.setup.activate gateway methods: detect lists every reusable backend it finds, activate live-tests one candidate (a real “reply with OK” completion) and only persists the model, workspace, and gateway defaults after the test passes. A failing candidate never changes config; the app automatically walks down the ladder and finally offers a manual key/token step populated from the Gateway’s active text-inference provider plugins. The selected provider owns its starter model and config, and the credential is verified the same way before it is saved.

​
AI conversation

Interactive Crestodian is AI-only: every message — including ones that look like typed commands — runs through the same embedded agent loop as regular OpenClaw agents, restricted to one ring-zero crestodian tool that wraps the typed operations. Read actions run freely, mutations require your conversational approval for that exact operation (see Operations and approval), and every applied write is audited and re-validated. The agent session persists, so the custodian has real multi-turn memory. It first uses the configured OpenClaw model; with no usable model it falls back to a local runtime already present on the machine, in setup-ladder order:
  • Claude Code CLI: claude-cli/claude-opus-4-8 (agent loop; the ring-zero tool is served over MCP, see the trust model below)
  • Codex app-server harness: openai/gpt-5.5 (agent loop with an enforced single-tool allow-list)
  • Gemini CLI: google-gemini-cli/gemini-3.1-pro-preview (agent loop; ring-zero tool over MCP)
When the agent loop is unavailable, Crestodian degrades to a bounded single-turn planner, and only without any usable model at all to deterministic typed commands. The planner cannot mutate config directly; it must translate the request into one of Crestodian’s typed commands, and normal approval/audit rules apply. Crestodian prints the model it used and the interpreted command before running anything. Fallback planner turns are temporary, tool-disabled where the runtime supports it, and use a temporary workspace/session. The typed command grammar is anchored: a message either matches a command exactly or it is conversation. Questions and natural phrasing (“why did my gateway stop?”) never trigger operations — they are answered by the AI. One secret-hygiene exception: an exact config set on a sensitive path (tokens, keys, passwords) never reaches a model. It runs on the deterministic path with a redacted proposal, and the value is masked in the AI-visible history. Prefer config set-ref <path> env <ENV_VAR> for secrets. Message-channel rescue mode never uses the model-assisted planner. Remote rescue stays deterministic so a broken or compromised normal agent path cannot be used as a config editor.

​
CLI harness trust model

Embedded runtimes and the Codex app-server harness enforce the ring-zero restriction directly: the run carries a tool allow-list with only the crestodian tool. CLI harnesses (Claude Code, Gemini CLI) cannot enforce an OpenClaw tool allow-list — the CLI owns its native tools and its own permission policy, so OpenClaw fails closed if asked to restrict one. For CLI-harness models Crestodian instead:
  • injects a dedicated MCP server that serves only the crestodian tool and replaces OpenClaw’s normal MCP tool surface for the run (for Claude Code the generated config is applied with --strict-mcp-config, so no other MCP servers are loaded),
  • keeps every config mutation inside the tool’s approval and audit contract — reads run freely, writes require your conversational yes, and every applied write is audited and re-validated,
  • leaves native tools (file reads, shell) to the harness. They follow the same permission posture as normal OpenClaw agent runs on this machine: with OpenClaw’s default exec settings Claude Code runs with permissions bypassed, and a restricted tools.exec config falls back to the CLI’s own permission policy.
Only Crestodian sessions get the crestodian MCP server; normal agent runs never see this tool. Treat a Crestodian session on a CLI-harness model like a normal local agent run on the same host: the ring-zero tool adds an audited, approval-gated path for config repair, but it does not prevent the harness’s native tools from touching files directly. The Codex app-server fallback and API-key models enforce the strict single-tool loop; prefer those when you want the hard restriction.

​
Switching to an agent

Use a natural-language selector to leave Crestodian and open the normal TUI: 
talk to agent
talk to work agent
switch to main agent
openclaw tui, openclaw chat, and openclaw terminal open the normal agent TUI directly; they do not start Crestodian. After switching into the normal TUI, /crestodian returns to Crestodian, optionally with a follow-up request: 
/crestodian
/crestodian restart gateway

​
Message rescue mode

Message rescue mode is the message-channel entrypoint for Crestodian: use it when your normal agent is dead but a trusted channel (for example WhatsApp) still receives commands. Supported command: /crestodian <request>. Rescue accepts the exact typed command grammar only — natural language is rejected with a hint, never guessed into an operation, and no model is ever consulted. 
You, in a trusted owner DM: /crestodian status
OpenClaw: Crestodian rescue mode. Gateway reachable: no. Config valid: no.
You: /crestodian restart gateway
OpenClaw: Plan: restart the Gateway. Reply /crestodian yes to apply.
You: /crestodian yes
OpenClaw: Applied. Audit entry written.
Agent creation can also be queued locally or via rescue: 
create agent work workspace ~/Projects/work model openai/gpt-5.5
/crestodian create agent work workspace ~/Projects/work
Remote rescue is an admin surface and must be treated like remote config repair, not normal chat. Security contract for remote rescue:
  • Disabled when sandboxing is active for the agent/session; Crestodian refuses remote rescue and points to local CLI repair.
  • Default effective state is auto: allow remote rescue only in trusted YOLO operation, where the runtime already has unsandboxed local authority (tools.exec.security resolves to full and tools.exec.ask resolves to off, with sandbox mode off).
  • Requires an explicit owner identity; no wildcard sender rules, open group policy, unauthenticated webhooks, or anonymous channels.
  • Owner DMs only by default; group/channel rescue needs explicit opt-in.
  • Plugin search and list are read-only. Plugin install is always local-only (blocked in rescue, even when otherwise enabled) because it downloads executable code. Plugin uninstall can be approved as a persistent rescue operation.
  • Remote rescue cannot open the local TUI or switch into an interactive agent session; use local openclaw for agent handoff.
  • Persistent writes still require approval, even in rescue mode.
  • Every applied rescue operation is audited. Message-channel rescue records channel, account, sender, and source-address metadata; config-mutating operations also record config hashes before and after.
  • Secrets are never echoed. SecretRef inspection reports availability, not values.
  • If the Gateway is alive, rescue prefers Gateway typed operations; if it is dead, rescue uses only the minimal local repair surface that does not depend on the normal agent loop.
Config shape: 
{
  "crestodian": {
    "rescue": {
      "enabled": "auto",
      "ownerDmOnly": true,
      "pendingTtlMinutes": 15,
    },
  },
}
  • enabled: "auto" (default) allows rescue only when the effective runtime is YOLO and sandboxing is off; false never allows message-channel rescue; true explicitly allows rescue when owner/channel checks pass (still subject to the sandboxing denial).
  • ownerDmOnly: restrict rescue to owner direct messages. Default true.
  • pendingTtlMinutes: how long a pending rescue write stays open for /crestodian yes approval before expiring. Default 15.
Remote rescue is covered by the Docker lane: 
pnpm test:docker:crestodian-rescue
Configless local planner fallback is covered by: 
pnpm test:docker:crestodian-planner
An opt-in live channel command-surface smoke checks /crestodian status plus a persistent approval roundtrip through the rescue handler: 
pnpm test:live:crestodian-rescue-channel
Configless setup through explicit Crestodian commands is covered by: 
pnpm test:docker:crestodian-first-run
That lane starts with an empty state dir, verifies the modern onboard Crestodian entrypoint, sets the default model, creates an additional agent, configures Discord through a plugin enablement plus token SecretRef, validates config, and checks the audit log. QA Lab has a repo-backed scenario for the same Ring 0 flow: 
pnpm openclaw qa suite --scenario crestodian-ring-zero-setup
