📚 Skills Reference

/aaron-review-my-code - Get Reviewed by the Creator

Get your ConnectOnion code reviewed by Aaron, the framework creator. Principled, educational review focused on correctness and elegance.

Usage:

# Review current file
/aaron-review-my-code

# Review specific file
/aaron-review-my-code path/to/agent.py

# Review entire project
/aaron-review-my-code .

What Aaron Checks:

✅ Correctness

• Proper Agent() initialization
• System prompts in markdown files
• Type hints on all tools
• Framework pattern compliance

✅ Elegance

• Code simplicity (fighting over-engineering)
• Proper tool patterns (function vs class)
• llm_do vs code usage
• Maintainability

✅ Philosophy Alignment

• "Keep simple things simple"
• No unnecessary abstractions
• Framework intent honored

Review Style:

• Constructive - Always teaching, never just criticizing
• Personal - From the creator who designed the patterns
• Educational - Explains WHY, not just WHAT
• Community-focused - Invites you to Discord for help

Example Output:

💡 Aaron says: agent.py:15

Here's what I'm seeing: Your tool function is missing type hints.

Why this matters: ConnectOnion uses type hints to automatically generate
tool schemas for the LLM. Without them, the agent can't understand what
parameters your tool needs.

Here's how I'd write it:
def search(query: str, limit: int = 10) -> str:
    """Search for information."""
    return f"Results for {query}"

ConnectOnion was designed for: Simple, type-safe tool definitions that
just work without configuration.

📚 Docs: https://docs.connectonion.com/tools/function-tools

At the End:

Every review ends with:

• Summary of critical vs nice-to-have fixes
• What you're doing right (always positive!)
• Specific next steps with file:line references
• Discord link to get help: https://discord.gg/4xfD9k8AUF
• Personal sign-off from Aaron

Best for:

• Learning ConnectOnion patterns from the creator
• Understanding framework philosophy
• Getting constructive, educational feedback
• Joining the community

/aaron-build-my-agent - Let the Creator Build Your Agent

Let Aaron (ConnectOnion creator) build your agent from scratch. He'll ask questions, choose the right pattern, and scaffold complete working code with explanations.

Usage:

/aaron-build-my-agent

Aaron will ask you:

1. What should your agent do? (e.g., "Screenshot websites", "Analyze code")
2. What operations does it need? (e.g., "Browser control", "File reading")
3. Does it need to remember things? (e.g., "Keep browser session open")

Then Aaron creates:

• 🛠️ Complete agent code - Ready to run
• 📝 System prompt file - In markdown (prompts/[agent_name].md)
• 🎯 Right pattern - Simple functions OR class instance based on needs
• ✅ Proper type hints - ConnectOnion requires them
• 📚 Explanation - Why he built it this way
• 🚀 Usage instructions - How to run and customize

Building Style:

• Personal - From the creator who designed the patterns
• Educational - Explains the "why" behind choices
• Simple first - Starts with simplest pattern that works
• Runnable - Code works immediately
• Customizable - Shows how to modify it

Example Interaction:

User: /aaron-build-my-agent

Aaron: Hey! What should your agent do?

User: Take screenshots of websites

Aaron: Great! Does it need to keep the browser open between screenshots?

User: Yes

Aaron: Perfect! I'll use a class instance pattern for stateful browser control.

[Generates complete browser agent with:
 - BrowserAutomation class
 - System prompt in prompts/web_assistant.md
 - Example usage
 - Explanation of pattern choice]

Aaron: Your agent is ready! I used Pattern B (class instance) because you need
to maintain browser state. The type hints tell ConnectOnion what parameters
each method needs. Check out Discord if you have questions! 🎯

At the end, every generated agent includes:

• Discord link to get help: https://discord.gg/4xfD9k8AUF
• GitHub issue reporting if something's wrong
• Customization guide
• Personal sign-off from Aaron

Best for:

• Building your first agent
• Learning ConnectOnion patterns from the creator
• Getting production-ready scaffolding
• Understanding framework design philosophy

/linus-review-my-code - Get Roasted for Complexity

Get direct, no-nonsense code review from Linus. Hunts down over-engineering and unnecessary complexity with brutal honesty.

Usage:

# Review current file
/linus-review-my-code

# Review specific file
/linus-review-my-code path/to/agent.py

# Review entire project
/linus-review-my-code .

What It Checks:

🚨 Over-Engineering Detection

• Unnecessary try-catch blocks
• Over-abstraction (factories, managers, helpers)
• Utils.py anti-pattern
• Long functions (>40 lines)
• Deep nesting

🚨 Code Smells

• Classes that should be functions
• Complex error handling infrastructure
• Unnecessary if-else chains
• Functions that don't fit on one screen

✅ ConnectOnion Patterns

• Type hints on tools
• System prompts in files
• Class instance usage
• Proper error handling

Review Philosophy:

• Direct and honest - Calls out bad code clearly
• Constructive - Shows simple solutions
• Educational - Explains WHY simplicity matters
• Focused - Only flags real problems

Example Output:

🚨 OVER-ENGINEERING at agent.py:25

Problem: Unnecessary try-catch that hides errors

try:
    result = do_something()
except Exception:
    pass  # This hides errors!

Why this is bad: You just made debugging impossible. If something fails, you WANT to know!

Fix:
result = do_something()  # Let it crash with a clear error message

Best for:

• Catching over-engineering early
• Learning "keep simple things simple"
• Getting honest feedback on code complexity
• Before committing large features

/generate-code-map-headers - Generate Code Map Headers

Generate code map headers that document dependencies, data flow, and integration points for each file.

Usage:

# Generate headers for all code files
/generate-code-map-headers

# Generate for specific directory or pattern
/generate-code-map-headers src/
/generate-code-map-headers **/*.py

What It Does:

1. Dependency Analysis

   • Builds import dependency graph
   • Identifies who imports what
   • Detects circular dependencies
   • Finds associated test files

2. Smart Documentation

   • Generates comprehensive file headers
   • Documents data flow and dependencies
   • Lists side effects and state changes
   • Includes integration points

3. Quality Tracking

   • Creates todo list for all files
   • Processes in dependency order (leaves first)
   • Skips already-documented files
   • Reports circular dependencies

Header Format:

"""
Purpose: [What problem this solves - one line]
LLM-Note:
  Dependencies: imports from [lib/database.py] | imported by [api/routes.py] | tested by [tests/test_module.py]
  Data flow: receives request_data: Dict → validates → queries database → returns ProcessedResult
  State/Effects: modifies global_cache | writes to PostgreSQL | publishes to Redis
  Integration: exposes process_data() | implements DataProcessor ABC | FastAPI dependency
  Performance: @lru_cache(maxsize=128) | asyncio.gather() | connection pool 10
  Errors: raises ValidationError | @retry(stop_after_attempt=3) | circuit breaker
"""

Quality Criteria:

• Clear visual hierarchy
• Consistent 8px spacing
• WCAG AA contrast
• Mobile-responsive
• Professional typography
• Proper interactive states

🎨 Key Patterns Enforced

Function-Based Tools (Recommended)

# ✅ Correct
def search(query: str, limit: int = 10) -> str:
    """Search for information."""
    return f"Found {limit} results"

agent = Agent("assistant", tools=[search])

Class Instance Tools (For State)

# ✅ Correct - pass instance
browser = BrowserAutomation()
agent = Agent("web", tools=[browser])  # Auto-discovers methods!

# ❌ Wrong - don't list methods
agent = Agent("web", tools=[browser.start, browser.goto, ...])  # Verbose!

System Prompts in Files

# ✅ Correct - markdown file
agent = Agent(
    name="assistant",
    system_prompt="prompts/assistant.md",  # Maintainable
    tools=[...]
)

# ❌ Wrong - inline string (unless very simple)
agent = Agent(
    name="assistant",
    system_prompt="You are an assistant...",  # Hard to maintain
    tools=[...]
)
