Workflow Engine

name: workflow-orchestrator description: Structural parity skeleton for queue-driven orchestration in a workflow context. user-invocable: true version: "0.1" allowed-tools: Read, Write, Edit, Grep, Glob, Bash argument-hint: "[target] [--handoff] [--batch ] [--type <extract|create|reflect|reweave|verify>]"

Contract

This skill is intentionally skeleton-only. It provides structure parity with canonical queue orchestration without plugin hooks.

Wave 2 execution parity includes:

• Setup derivation phase ordering: detection -> understanding -> derivation -> proposal -> generation -> validation
• Required persisted setup artifacts: ops/derivation.md, ops/derivation-manifest.md, ops/config.yaml
• In-skill lifecycle emulation routines (not real hook execution):
  • session orient
  • write-time validation checklist
  • stop/session capture persistence

Argument Parsing

Parse arguments in this order:

1. positional target (optional)
2. --handoff (boolean)
3. --batch <id> (optional)
4. --type <phase> (optional)
5. unknown flags are non-fatal; report and ignore

If no target is supplied, list candidate inbox files and request explicit selection.

Runtime Loader Requirements

Before doing queue work, load runtime context from:

• ops/derivation-manifest.md (if present)
• ops/config.yaml (if present)
• queue file with fallback precedence:
  1. ops/queue/queue.yaml
  2. ops/queue/queue.yml
  3. ops/queue/queue.json

If no queue file exists, fail safely with actionable remediation.

Safety Constraints

Never:

• execute arbitrary shell from user-provided strings
• continue processing after parse/load failures
• mutate tasks outside declared queue schema fields
• call external plugins/hooks (explicitly out of scope)

Always:

• validate queue structure before state transitions
• make state transitions explicit (extract -> create -> reflect -> reweave -> verify -> done)
• produce deterministic handoff text when --handoff is set
• preserve resumability by reading persisted queue state first

Scope Boundary

No plugin hooks are implemented in this skeleton. Lifecycle behavior is emulated in-skill to preserve deterministic execution semantics only.

Installation

To install the workflow-engine and enable its hooks:

# Clone or navigate to the workflow-engine directory
cd workflow-engine

# Run the install script to set up hooks
./install-hooks.sh

# Or manually enable hooks via openclaw
openclaw hooks enable session-orient
openclaw hooks enable write-validate
openclaw hooks enable session-capture
