Install the lobster skill

A skill is a folder. Copy it into your agent's skills folder and the agent loads it when the task matches its description.

git clone --depth 1 https://github.com/openclaw/openclaw.git /tmp/openclaw
mkdir -p ~/.claude/skills
cp -r /tmp/openclaw/extensions/lobster ~/.claude/skills/lobster
available in every project

In the Claude apps, zip the folder and upload it from the Skills settings. The folder on GitHub

Lobster

Lobster executes multi-step workflows with approval checkpoints. Use it when:

  • User wants a repeatable automation (triage, monitor, sync)
  • Actions need human approval before executing (send, post, delete)
  • Multiple tool calls should run as one repeatable operation

When to use Lobster

Basic usage

Run a pipeline

{
  "action": "run",
  "pipeline": "gog.gmail.search --query 'newer_than:1d' --max 20 | email.triage"
}

Returns structured result:

{
  "protocolVersion": 1,
  "ok": true,
  "status": "ok",
  "output": [{ "summary": {...}, "items": [...] }],
  "requiresApproval": null
}

Handle approval

If the workflow needs approval:

{
  "status": "needs_approval",
  "output": [],
  "requiresApproval": {
    "prompt": "Send 3 draft replies?",
    "items": [...],
    "resumeToken": "..."
  }
}

Present the prompt to the user. If they approve:

{
  "action": "resume",
  "token": "<resumeToken>",
  "approve": true
}

Example workflows

Email triage

gog.gmail.search --query 'newer_than:1d' --max 20 | email.triage

Fetches recent emails, classifies into buckets (needsreply, needsaction, fyi).

Email triage with approval gate

gog.gmail.search --query 'newer_than:1d' | email.triage | approve --prompt 'Process these?'

Same as above, but halts for approval before returning.

Key behaviors

  • Deterministic: Same input → same output (no LLM variance in pipeline execution)
  • Approval gates: approve command halts execution, returns token
  • Resumable: Use resume action with token to continue
  • Structured output: Always returns JSON envelope with protocolVersion

Don't use Lobster for

  • Simple single-action requests (just use the tool directly)
  • Queries that need LLM interpretation mid-flow
  • One-off tasks that won't be repeated
