Agno agents move fast when tools are convenient, which is exactly when a remote Mac becomes a liability without a hard trust boundary. This HowTo keeps OpenClaw in front: a gateway tool whitelist, nested request timeouts that trip before your process wedges, a circuit breaker that stops retry storms, and a failure summary JSON object your orchestration code can branch on instead of scraping logs.

Pain points this runbook removes

1. Shadow tools. Developers register helpers locally while production gateways lag, so some invocations skip the policy you thought was universal.

2. Ambiguous hangs. One giant HTTP deadline masks whether the model, schema validation, or a downstream API stalled, so operators restart blindly.

3. Retry amplification. Without a breaker, flaky upstreams and validator faults loop until unified memory pressure spikes on the same rented host.

Where each layer should live

Layer Owns inside Agno Owns at OpenClaw gateway
Tool surface Python callables, docstrings, argument shaping for the model. Allowlisted route names, transport auth, per-route JSON Schema registration.
Time budgets Outer HTTP client deadline a few seconds above gateway fuses. Validation wall clock, execution ceiling, queue wait cap, breaker cooldown.
Failure UX Branch on structured envelope, bounded repair attempts on fields. Emit correlation id, stage, code, optional JSON pointer, redacted remediation text.

Pre-flight inspection with openclaw doctor

Before you point Agno at a loopback base URL, treat openclaw doctor --json as a gate. Archive its output beside the OpenClaw version string you pinned. Fix path warnings, permission errors on token files, and any missing optional components you rely on for routing. Doctor is cheap insurance compared to debugging half-registered tools while traffic is live.

Run doctor again after macOS minor upgrades, Homebrew churn, or Python virtualenv rebuilds on the remote Mac. Drift between doctor output and your checked-in route manifest should block deploy scripts non-zero.

Gateway JSON fragments (no secrets in git)

Keep bearer material in a chmod 600 file or your secret manager; reference it only from environment variables on the host. The snippets below illustrate shape only.

Allowlisted tools and schema handles

{ "version": 1, "tools": [ { "name": "read_repo_file", "argsSchemaRef": "schemas/read_repo_file.json" }, { "name": "append_audit_log", "argsSchemaRef": "schemas/append_audit_log.json" } ], "denyUnknownToolNames": true }

Timeout fuse and breaker policy

{ "validateTimeoutMs": 8000, "executeTimeoutMs": 52000, "clientHintTimeoutMs": 60000, "breaker": { "openAfterFailures": 3, "cooldownSeconds": 30 } }

Failure summary envelope returned to Agno

{ "ok": false, "correlationId": "req_01hzzexample", "stage": "validate", "code": "schema_timeout", "pointer": "/items/0/title", "hint": "Reduce payload size or split the tool batch." }

Reproducible steps

  1. Bootstrap runtimes. Pin Node 22 LTS for OpenClaw, create a Python virtual environment for Agno, record interpreter paths in launchd plist or a systemd user unit, and mount a dedicated scratch directory on SSD.
  2. Pre-flight. Install the pinned OpenClaw build, run openclaw doctor --json, resolve every warning, then start openclaw gateway listen bound to 127.0.0.1 with your token file outside the repository.
  3. Expose only what you intend. Reach the gateway through SSH -R or a private mesh; block public ingress; keep dashboard tokens out of the Agno repo.
  4. Sync allowlists at startup. Load the JSON tool manifest in both places. If any Agno tool name is missing from the gateway list, or the reverse, exit before serving requests.
  5. Wire Agno HTTP to the tunneled base URL. Set the OpenAI-compatible base URL environment variable to your loopback port, set the Agno client timeout above executeTimeoutMs but below operator panic thresholds, and enable structured logging to JSONL.
  6. Map gateway faults to envelopes. Translate transport errors, validation timeouts, breaker opens, and upstream five hundreds into the compact JSON shape so your agent loop can retry, escalate, or stop deterministically.
  7. Smoke three cases. Happy path tool call, deliberate schema violation, and stalled upstream to verify fuse ordering, breaker counters, and log fields match the runbook.

Troubleshooting

  • Breaker opens while the model still streams. Invalid structured tool payloads count as failures. Widen schema or tighten prompts; do not disable gateway validation in production.
  • Doctor passes but tools vanish after upgrade. Diff your route manifest against the new OpenClaw defaults and confirm session or visibility flags did not tighten silently.
  • Tunnel drops overnight. Enable TCP keepalives on SSH client and server, assign an on-call owner, and alert on the same health probe path Agno uses.

Citable guardrails

  • Keep validateTimeoutMs at eight thousand milliseconds or less when outer clients sit near one minute.
  • Open the breaker after three consecutive failures and enforce a thirty second cooldown before half-open probes.
  • Rotate JSONL weekly and compress shards beyond two hundred megabytes so storage stays predictable under bursts.

FAQ

Should Agno validate arguments locally too? Useful for inner-loop speed, but the gateway remains authoritative so every caller shares one contract.

Where do bounded retries belong? After the breaker allows traffic again, let Agno perform at most one or two repair attempts on structured fields; let OpenClaw own transport-aware backoff.

Summary: Run doctor before cutover, mirror a minimal tool JSON manifest at OpenClaw, nest validation and execution timeouts under the Agno client budget, trip a breaker on repeated faults, and return redacted failure summaries so remote Mac agents stay auditable.
