Agent Development Guide

This guide provides comprehensive instructions for creating cs- prefixed agents* that seamlessly integrate with the 42 production skills in this repository.

Agent Architecture

What are cs-* Agents?

cs- agents* are specialized Claude Code agents that orchestrate the 177 existing skills. Each agent:

• References skills via relative paths (../../marketing-skill/)
• Executes Python automation tools from skill packages
• Follows established workflows and templates
• Maintains skill portability and independence

Key Principle: Agents ORCHESTRATE skills, they don't replace them. Skills remain self-contained and portable.

ClawHub Publishing Constraints

When skills are published to ClawHub (clawhub.com):

• cs- prefix for slug conflicts only — applies only on the ClawHub registry when another publisher already owns the slug. Repo folder names and local skill names are never renamed.
• No paid/commercial service dependencies — skills must not require paid third-party API keys or commercial services unless provided by the project itself.
• plugin.json — ONLY fields: name, description, version, author, homepage, repository, license, skills: "./".
• Rate limit: 5 new skills/hour on ClawHub. Use drip publishing for bulk operations.

Agent vs Skill

Agent File Structure

Required YAML Frontmatter

Every agent file must start with valid YAML frontmatter:

---
name: cs-agent-name
description: One-line description of what this agent does
skills: skill-folder-name
domain: domain-name
model: sonnet
tools: [Read, Write, Bash, Grep, Glob]
---

Field Definitions:

• name: Agent identifier with cs- prefix (e.g., cs-content-creator)
• description: Single sentence describing agent's purpose
• skills: Skill folder this agent references (e.g., marketing-skill/content-creator)
• domain: Domain category (marketing, product, engineering, c-level, pm, ra-qm)
• model: Claude model to use (sonnet, opus, haiku)
• tools: Array of Claude Code tools agent can use

Required Markdown Sections

After YAML frontmatter, include these sections:

1. Purpose (2-3 paragraphs)
2. Skill Integration (with subsections)
   • Skill Location
   • Python Tools
   • Knowledge Bases
   • Templates
3. Workflows (minimum 3 workflows)
4. Integration Examples (concrete code/command examples)
5. Success Metrics (how to measure effectiveness)
6. Related Agents (cross-references)
7. References (links to documentation)

Relative Path Resolution

Path Pattern

All skill references use the ../../ pattern:

**Skill Location:** `../../marketing-skill/content-creator/`

### Python Tools

1. **Brand Voice Analyzer**
   - **Path:** `../../marketing-skill/content-creator/scripts/brand_voice_analyzer.py`
   - **Usage:** `python ../../marketing-skill/content-creator/scripts/brand_voice_analyzer.py content.txt`

2. **SEO Optimizer**
   - **Path:** `../../marketing-skill/content-creator/scripts/seo_optimizer.py`
   - **Usage:** `python ../../marketing-skill/content-creator/scripts/seo_optimizer.py article.md "keyword"`

Why ../../?

From agent location: agents/marketing/cs-content-creator.md To skill location: marketing-skill/content-creator/

Navigation: agents/marketing/ → ../../ (up to root) → marketing-skill/content-creator/

Always test paths resolve correctly!

Python Tool Integration

Execution Pattern

Agents execute Python tools from skill packages:

# From agent context
python ../../marketing-skill/content-creator/scripts/brand_voice_analyzer.py input.txt

# With JSON output
python ../../marketing-skill/content-creator/scripts/brand_voice_analyzer.py input.txt json

# With arguments
python ../../product-team/product-manager-toolkit/scripts/rice_prioritizer.py features.csv --capacity 20

Tool Requirements

All Python tools must:

• Use standard library only (or minimal dependencies documented in SKILL.md)
• Support both JSON and human-readable output
• Provide --help flag with usage information
• Return appropriate exit codes (0 = success, 1 = error)
• Handle missing arguments gracefully

Error Handling

When Python tools fail:

1. Check file path resolution
2. Verify input file exists
3. Check Python version compatibility (3.8+)
4. Review tool's --help output
5. Inspect error messages in stderr

Workflow Documentation

Workflow Structure

Each workflow must include:

### Workflow 1: [Clear Descriptive Name]

**Goal:** One-sentence description

**Steps:**
1. **[Action]** - Description with specific commands/tools
2. **[Action]** - Description with specific commands/tools
3. **[Action]** - Description with specific commands/tools

**Expected Output:** What success looks like

**Time Estimate:** How long this workflow takes

**Example:**
\`\`\`bash
# Concrete example command
python ../../marketing-skill/content-creator/scripts/seo_optimizer.py article.md "primary keyword"
\`\`\`

Minimum Requirements

Each agent must document at least 3 workflows covering:

1. Primary use case (most common scenario)
2. Advanced use case (complex scenario)
3. Integration use case (combining multiple tools)

Agent Template

Use this template when creating new agents:

---
name: cs-agent-name
description: One-line description
skills: skill-folder-name
domain: domain-name
model: sonnet
tools: [Read, Write, Bash, Grep, Glob]
---

# Agent Name

## Purpose

[2-3 paragraphs describing what this agent does, why it exists, and who it serves]

## Skill Integration

**Skill Location:** \`../../domain-skill/skill-name/\`

### Python Tools

1. **Tool Name**
   - **Purpose:** What it does
   - **Path:** \`../../domain-skill/skill-name/scripts/tool.py\`
   - **Usage:** \`python ../../domain-skill/skill-name/scripts/tool.py [args]\`

### Knowledge Bases

1. **Reference Name**
   - **Location:** \`../../domain-skill/skill-name/references/file.md\`
   - **Content:** What's inside

### Templates

1. **Template Name**
   - **Location:** \`../../domain-skill/skill-name/assets/template.md\`
   - **Use Case:** When to use

## Workflows

### Workflow 1: [Name]

Quality Standards

Agent Quality Checklist

Before committing an agent:

• YAML frontmatter valid (no parsing errors)
• All required fields present (name, description, skills, domain, model, tools)
• cs-* prefix used for agent naming
• Relative paths resolve correctly (../../ pattern)
• Skill location documented and accessible
• Python tools referenced with correct paths
• At least 3 workflows documented
• Integration examples provided and tested
• Success metrics defined
• Related agents cross-referenced

Testing Agent Integration

Test these aspects:

1. Path Resolution

# From agent directory
cd agents/marketing/
ls ../../marketing-skill/content-creator/  # Should list contents

2. Python Tool Execution

# Create test input
echo "Test content" > test-input.txt

# Execute tool
python ../../marketing-skill/content-creator/scripts/brand_voice_analyzer.py test-input.txt

# Verify output

3. Knowledge Base Access

# Verify reference files exist
cat ../../marketing-skill/content-creator/references/brand_guidelines.md

Domain-Specific Guidelines

• Focus on content creation, SEO, demand generation
• Reference: ../../marketing-skill/
• Tools: brand_voice_analyzer.py, seo_optimizer.py

Product Agents (agents/product/)

• Focus on prioritization, user research, agile workflows
• Reference: ../../product-team/
• Tools: rice_prioritizer.py, user_story_generator.py, okr_cascade_generator.py

C-Level Agents (agents/c-level/)

• Focus on strategic decision-making
• Reference: ../../c-level-advisor/
• Tools: Strategic analysis and planning tools

Engineering Agents (agents/engineering/)

• Focus on scaffolding, code quality, fullstack development
• Reference: ../../engineering-team/
• Tools: project_scaffolder.py, code_quality_analyzer.py

Common Pitfalls

Avoid these mistakes:

❌ Hardcoding absolute paths ❌ Skipping YAML frontmatter validation ❌ Forgetting to test relative paths ❌ Documenting workflows without examples ❌ Creating agent dependencies (keep them independent) ❌ Duplicating skill content in agent files ❌ Using LLM calls instead of referencing Python tools

Next Steps

After creating an agent:

1. Test all relative paths resolve
2. Execute all Python tools from agent context
3. Verify all workflows with concrete examples
4. Update agent catalog in main README.md
5. Create GitHub issue for agent testing
6. Commit with conventional commit message: feat(agents): implement cs-agent-name
