At a glance

Diagnose Gateway, config, secrets, channels, and port failures with read-only one-liners.

  • SKILL.md covers Gather, Mutate, Repair and Prove, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Diagnose Gateway is an agent skill from openclaw/openclaw. Diagnose Gateway, config, secrets, channels, and port failures with read-only one-liners.

Its SKILL.md is about 670 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: The AI that really does things. Any OS. Any Platform. The lobster way. 🦞. The licence is MIT.

Example prompts

  • “/diagnose-gateway”

What it can do on your machine

Read from SKILL.md and the folder at commit f8e594e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • docs.openclaw.ai

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Diagnose Gateway loads about 670 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 308 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~27
When it runs · the whole SKILL.md, loaded when a task matches
~670

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Diagnose the Gateway

This playbook is read-only: no config writes, no service restarts, no doctor --fix, no killing listeners. Never print secret values; report only redacted SecretRef owner state. Every run ends with the observable Prove result or an exact explanation of why it could not be proven.

Gather

openclaw doctor --lint
openclaw gateway status --deep
openclaw config validate
openclaw channels status
openclaw models status
openclaw channels logs --channel <id>

doctor --lint is read-only and can exit 1 for findings: read the report and continue the remaining checks. Do not substitute ordinary doctor or doctor --non-interactive; they can copy legacy config and migrate state without --fix.

On managed installs, bounded recent logs: ./scripts/clawlog.sh (repo checkout) or the log path printed at gateway startup (/tmp/openclaw/openclaw-<date>.log by default).

Check these signatures without guessing:

  • invalid config or schema errors (config validate names the exact key and line);
  • degraded SecretRef owners — report the owner, never ids or values;
  • expired or rejected channel authentication (channels status per account);
  • EADDRINUSE, a second gateway listener, or service/config port mismatch (lsof -nP -iTCP:<port> -sTCP:LISTEN);
  • gateway crash loops: read the last startup stack in the gateway log; a schema-valid config that still crashes startup is a bug — capture the stack and report it.

Correlate timestamps and identify the first owner-boundary failure.

Mutate

Nothing. Do not change config, migrate state, or alter services. Diagnostic commands may still produce incidental logs or cache bookkeeping.

Repair

Translate each finding into the next action, naming the responsible skill when one exists: configure-channel, add-model-provider, or cloud-image-bake. Recommend openclaw doctor --fix --non-interactive only as a separately approved step.

Prove

Repeat the smallest read-only check that exposes the condition and record its output, for example:

openclaw gateway status --deep
openclaw channels status --probe

If access, logs, or the gateway are unavailable, report that exact blocker rather than declaring a cause.

Report

Findings in causal order with evidence for each; current gateway/config/SecretRef/channel/port state; one recommended next skill or operator action. State explicitly that no config/service repairs or state migrations were performed.
