Setup snapshot

git clone https://github.com/leefowlercu/agent-skill-agent-skill-builder.git

1
Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.
2
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

name: Building Agent Skills description: Assists in creating Agent Skills of varying complexity levels (simple, moderate, complex). Use when the user wants to create, design, or build a new Agent Skill, or when they need guidance on skill architecture, workflow design, schema validation, or template structure.

Overview

This skill enables the creation of Agent Skills following established best practices and patterns. It provides a structured workflow for gathering requirements, determining appropriate complexity (archetype), planning structure, generating artifacts, and validating the resulting skill.

The skill supports three archetypes:

Simple: Single SKILL.md with inline instructions
Moderate: SKILL.md with separate reference files
Complex: Full Phase/Stage/Step hierarchy with schemas and scripts

Overview
Table of Contents
Prerequisites
Workflow: Building Agent Skills

Prerequisites

Before starting the workflow you MUST:

Present complete workflow structure (Phases, Stages, Steps) to user
Explain Phase approval gates
Wait for user acknowledgment

Workflow: Building Agent Skills

This workflow guides you through creating an Agent Skill from requirements to validation. The workflow is organized into four distinct phases:

Phase 1: Discovery - Gather requirements and analyze complexity needs.

Phase 2: Planning - Design the skill structure and file organization.

Phase 3: Implementation - Generate all skill artifacts.

Phase 4: Validation & Iteration - Validate the skill and refine based on feedback.

Important Workflow Guidelines

When executing this workflow you MUST:

Follow Phases, Stages, and Steps in order
Announce Stage completions to the user
Present complete Phase output at Phase boundaries
Obtain explicit user approval before proceeding to the next Phase

Phase 1: Discovery

Stage 1: Requirements Gathering

Objective: Understand what the user needs to build

Step 1: Gathering Requirements

See Gathering Requirements Workflow Step Reference for detailed guidance.

Stage 2: Analysis

Objective: Determine appropriate skill architecture

Step 2: Determining Archetype

See Determining Archetype Workflow Step Reference for detailed guidance.

Phase 1 Approval Gate: Present complete requirements and archetype decision. Obtain explicit user approval before Phase 2.

Phase 2: Planning

Stage 3: Design

Objective: Create approved blueprint for the skill

Step 3: Planning Structure

See Planning Structure Workflow Step Reference for detailed guidance.

Phase 2 Approval Gate: Present complete structure plan including file manifest and generation order. Obtain explicit user approval before Phase 3.

Phase 3: Implementation

Stage 4: Foundation

Objective: Generate core skill definition

Step 4: Generating SKILL.md

See Generating SKILL.md Workflow Step Reference for detailed guidance.

Stage 5: References

Objective: Generate supporting documentation

Step 5: Generating Workflow References

See Generating Workflow References Step Reference for detailed guidance.

Step 6: Generating Schemas

See Generating Schemas Workflow Step Reference for detailed guidance.

Stage 6: Automation

Objective: Generate executable components

Step 7: Generating Scripts

See Generating Scripts Workflow Step Reference for detailed guidance.

Phase 3 Approval Gate: Present all generated artifacts for review. Obtain explicit user approval before Phase 4.

Phase 4: Validation & Iteration

Stage 7: Quality Assurance

Objective: Verify skill correctness

Step 8: Validating Skill

See Validating Skill Workflow Step Reference for detailed guidance.

Stage 8: Refinement

Objective: Incorporate user feedback

Step 9: Iterating on Feedback

See Iterating on Feedback Workflow Step Reference for detailed guidance.
