Changelog

All notable changes to Lobster will be documented in this file.

Unreleased

  • Improve workflow resume compatibility for stateKey naming by accepting both workflow_resume_ and workflow-resume_ prefixes, including cleanup against the resolved on-disk key. Thanks to @brownetw-ai (PR #4).
  • Add per-step workflow retry policies (max, backoff, delay_ms, max_delay_ms, jitter) with retry-aware stderr logs and dry-run visibility. Thanks to @scottgl9 (PR #84).
  • Add optional approval identity constraints for workflow gates (approval.initiated_by, approval.required_approver, approval.require_different_approver) with resume-time enforcement via LOBSTER_APPROVAL_APPROVED_BY and envelope metadata for integrations. Thanks to @coolmanns (Issue #44).
  • Clarify pipeline: vs run: usage for llm.invoke / llm_task.invoke in workflow files, and add regression coverage to ensure stdin: $step.stdout is forwarded as LLM artifacts for llm_task.invoke pipeline steps. Thanks to @RatkoJ (Issue #41).
  • Add lobster graph workflow visualization with mermaid (default), dot, and ascii outputs, including step-type nodes, stdin data-flow edges, conditional dependency labels (when/condition), approval-gate diamond shapes, and --args-json label resolution support. Thanks to @vignesh07 (Issue #53).
  • Add workflow composition via workflow: + workflow_args, including recursive sub-workflow execution, cycle detection, and dry-run visibility for workflow steps. Sub-workflow approval/input halts are rejected with resume-state cleanup. Thanks to @scottgl9 (PR #73).
  • Add per-step on_error workflow policies (stop|continue|skip_rest) for partial-failure recovery, with structured step error fields (error, errorMessage) for condition-based branching. Thanks to @scottgl9 (PR #72).
  • Add per-step workflow timeout_ms handling, including timeout-triggered aborts, SIGKILL for timed shell steps, and dry-run annotations. Thanks to @scottgl9 (PR #74).
  • Add workflow condition comparison operators <, <=, >, and >= with strict numeric semantics (booleans/null do not coerce), including mixed boolean-expression support with &&/||. Thanks to @scottgl9 (PR #71).
  • Add workflow-level LLM cost tracking with _meta.cost summaries, per-step usage attribution, and optional cost_limit controls with warn/stop actions (plus custom pricing via LOBSTER_LLM_PRICING_JSON). Thanks to @scottgl9 (PR #70).
  • Add parallel workflow steps with branch fan-out, wait: all|any, block-level timeout support, and branch result references in downstream steps. Thanks to @scottgl9 (PR #69).
  • Add for_each workflow steps for per-item sub-step execution over arrays, including loop-scoped vars (item_var/index_var), optional batch_size + pause_ms, and collected iteration outputs for downstream steps. Thanks to @scottgl9 (PR #68).
  • Add pipe-based template filters (for example upper, length, join, default, date) for the template command with quote-aware filter parsing and chain evaluation. Thanks to @scottgl9 (PR #67).

2026.4.6

  • Add workflow file support for .lobster, YAML, and JSON, including workflow args/env, native pipeline steps, and shell-safe LOBSTER_ARG_* inputs.
  • Add structured input pauses with ask, workflow input, needs_input, and lobster resume --response-json '{...}' for resumable human-in-the-loop flows.
  • Add richer workflow condition expressions with !, ==, !=, &&, ||, and parentheses.
  • Export the embeddable runtime via @clawdbot/lobster/core so Lobster can run in-process inside OpenClaw and other hosts.
  • Add generic llm.invoke adapters, openclaw.invoke --each, and keep clawd.invoke as a supported alias.
  • Add compact state-backed workflow/pipeline resume tokens, safer resume validation, and hardened approval ID handling.
  • Improve dry-run and shell interoperability with exec --stdin raw|json|jsonl, approve --preview-from-stdin --limit N, and better template/shell-variable preservation.
  • Improve Windows CLI/build compatibility and fix quoted-argument parser edge cases.
