Workflow executor

Workflow Auto-Executor

This skill automatically executes custom workflows by:

1. Loading the workflow definition
2. Preparing the execution plan
3. Invoking each command via Skill tool
4. Integrating with backlog.md via MCP

Usage

# Invoke this skill from Claude Code:
/workflow-executor quick_build

# Or with context:
/workflow-executor full_design --context complexity=8

Implementation

This skill bridges the gap between CLI infrastructure (which prepares execution plans) and agent execution (which actually runs workflows).

Integration with MCP Backlog

When executing in agent context, the skill can update backlog tasks:

# Get current task from context (if available)
task_id = os.environ.get("CURRENT_TASK_ID")

if task_id:
    # Update task status via MCP
    mcp__backlog__task_edit(
        id=task_id,
        status="In Progress",
        notesAppend=[f"Executing workflow: {workflow_name}"]
    )

    # After workflow completion
    mcp__backlog__task_edit(
        id=task_id,
        status="Done",
        notesAppend=[f"Workflow {workflow_name} completed successfully"]
    )

Agent Context Detection

The skill detects whether it's running in agent context:

import sys

def is_agent_context() -> bool:
    """Check if running in Claude Code agent context."""
    # In agent context, certain modules/functions are available
    # In subprocess context, they're not
    try:
        # This would only work in agent context
        # (This is a placeholder check)
        return hasattr(sys, '_claude_code_agent')
    except:
        return False

if is_agent_context():
    # Can use Skill tool and MCP tools
    print("Running in agent context - full execution enabled")
else:
    # Running as subprocess - log only mode
    print("Running as subprocess - displaying execution plan only")

Example Execution

# From Claude Code:
/workflow-executor quick_build

# Output:
🚀 Auto-executing workflow: quick_build

📋 Execution plan prepared:
   Steps to execute: 3
   Steps to skip: 0

Benefits

1. Full automation: No manual step invocation needed
2. Backlog integration: Auto-updates task status via MCP
3. Rigor enforcement: All logging preserved
4. Error handling: Graceful failure with continue-on-error
5. Context support: Pass complexity scores, etc.
