npm package: @metaverse-dc/lobster
Description: Workflow runtime for AI agents — deterministic pipelines with approval gates. Forked from @clawdbot/lobster with security hardening for CEO OS.
Latest version: 1.0.0

# Lobster

An OpenClaw-native workflow shell: typed (JSON-first) pipelines, jobs, and approval gates.


## Example of Lobster at work
OpenClaw (or any other AI agent) can use `lobster` as a workflow engine and avoid re-planning every step — saving tokens while improving determinism and resumability.

### Watching a PR that hasn't had changes
```
node bin/lobster.js "workflows.run --name github.pr.monitor --args-json '{\"repo\":\"openclaw/openclaw\",\"pr\":1152}'"
[
  {
    "kind": "github.pr.monitor",
    "repo": "openclaw/openclaw",
    "prNumber": 1152,
    "key": "github.pr:openclaw/openclaw#1152",
    "changed": false,
    "summary": {
      "changedFields": [],
      "changes": {}
    },
    "prSnapshot": {
      "author": {
        "id": "MDQ6VXNlcjE0MzY4NTM=",
        "is_bot": false,
        "login": "vignesh07",
        "name": "Vignesh"
      },
      "baseRefName": "main",
      "headRefName": "feat/lobster-plugin",
      "isDraft": false,
      "mergeable": "MERGEABLE",

### And a PR that has a state change (in this case an approved PR)

```
 node bin/lobster.js "workflows.run --name github.pr.monitor --args-json '{\"repo\":\"openclaw/openclaw\",\"pr\":1200}'"
[

        },
        "mergeable": {
          "from": null,
          "to": "UNKNOWN"
        },
        "reviewDecision": {

    }
  }
]
```

## Goals


- Typed pipelines (objects/arrays), not text pipes.
- Local-first execution.
- No new auth surface: Lobster must not own OAuth/tokens.
- Composable macros that OpenClaw (or any agent) can invoke in one step to save tokens.

## Quick start

From this folder:

- `pnpm install`
- `pnpm test`
- `pnpm lint`
- `node ./bin/lobster.js --help`
- `node ./bin/lobster.js doctor`
- `node ./bin/lobster.js "exec --json --shell 'echo [1,2,3]' | where '0>=0' | json"`

### Notes

- `pnpm test` runs `tsc` and then executes tests against `dist/`.
- `bin/lobster.js` prefers the compiled entrypoint in `dist/` when present.
## Commands

- `exec`: run OS commands
- `exec --stdin raw|json|jsonl`: feed pipeline input into subprocess stdin
- `where`, `pick`, `head`: data shaping
- `json`, `table`: renderers
- `approve`: approval gate (TTY prompt or `--emit` for OpenClaw integration)

## Next steps

- OpenClaw integration: ship as an optional OpenClaw plugin tool.

## Workflow files

Lobster can run YAML/JSON workflow files with `steps`, `env`, `condition`, and approval gates.

```
lobster run path/to/workflow.lobster
lobster run --file path/to/workflow.lobster --args-json '{"tag":"family"}'
```

Example file:

```yaml
name: inbox-triage
steps:
  - id: collect
    command: inbox list --json
  - id: categorize
    command: inbox categorize --json
    stdin: $collect.stdout
  - id: approve
    command: inbox apply --approve
    stdin: $categorize.stdout
    approval: required
  - id: execute
    command: inbox apply --execute
    stdin: $categorize.stdout
    condition: $approve.approved
```
