• /tasks completes
• tasks.md updated
• "parallelize spec"
• "spawn spec tasks"

Spec Kit Parallel Executor

I automatically detect when Spec Kit tasks have parallel-eligible items and offer to spawn agents.

Activation

I activate when:

• /tasks command completes
• User explicitly requests spec parallelization
• .spec/tasks.md is updated with new tasks

Detection Logic

def should_parallelize(tasks_file):
    tasks = parse_tasks(tasks_file)
    parallel_tasks = [t for t in tasks if "[P]" in t or "(P)" in t]
    return len(parallel_tasks) >= 3

Spec Context

I include all Spec Kit artifacts in each agent's context:

Agent Prompt Template

You are a Spec Kit implementation agent.
 
## Your Task
{task_description}
 
## Feature Specification
{spec_content}
 
## Implementation Plan
{plan_content}
 
## Design Decisions
{design_content}
 
## Instructions
1. Implement ONLY the assigned task
2. Follow the specification exactly
3. Adhere to the implementation plan
4. Write tests for new functionality
5. Commit with message: "feat(spec): {task_name}"
6. Output TASK_COMPLETE when done
 
Begin implementation.

Integration with Base

This skill extends the base parallel-executor skill:

• Uses same worktree pattern
• Same monitoring commands
• Same merge workflow

Spec Validation

After tasks complete, I can validate against spec:

# Check each worktree's implementation
for wt in ../project-*; do
    claude -p "Validate implementation in $wt against .spec/spec.md" --print
done
