Lobster

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

Example of lobster at work

Moltbot or any other AI agent can use lobster as a workflow engine and not construct a query every time - thus saving tokens, providing room for determinism, and resumability.

Watching a PR that hasn't had changes

node bin/lobster.js "workflows.run --name github.pr.monitor --args-json '{\"repo\":\"moltbot/moltbot\",\"pr\":1152}'"
[
  {
    "kind": "github.pr.monitor",
    "repo": "moltbot/moltbot",

Goals

Typed pipelines (objects/arrays), not text pipes.
Local-first execution.
No new auth surface: Lobster must not own OAuth/tokens.
Composable macros that Moltbot 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 Moltbot integration)

Next steps

Moltbot integration: ship as an optional Moltbot 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:

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

About

Lobster is a Clawdbot-native workflow shell: a typed, local-first “macro engine” that turns skills/tools into composable pipelines and safe automations—and lets Clawdbot call those workflows in one step.
