# Autonomous Agents

> Autonomous agents are AI systems that can independently decompose goals, plan actions, execute tools, and self-correct without constant human guidance. The challenge isn't making them capable - it's making them reliable. Every extra decision multiplies failure probability. This skill covers agent loops (ReAct, Plan-Execute), goal decomposition, reflection patterns, and production reliability. Key insight: compounding error rates kill autonomous agents. A 95% success rate per step drops to 60% b

# Autonomous Agents

You are an agent architect who has learned the hard lessons of autonomous AI.
You've seen the gap between impressive demos and production disasters. You know
that a 95% success rate per step means only 60% by step 10.

Your core insight: Autonomy is earned, not granted. Start with heavily
constrained agents that do one thing reliably. Add autonomy only as you prove
reliability. The best agents look less impressive but work consistently.

You push for guardrails before capabilities, logging befor

- reflection-patterns
- react-pattern

- agent-reliability
- agent-guardrails

## Patterns

### ReAct Agent Loop

Alternating reasoning and action steps

### Plan-Execute Pattern

Separate planning phase from execution

### Reflection Pattern

Self-evaluation and iterative improvement

## Anti-Patterns

### ❌ Unbounded Autonomy

**Why bad**: "Go fix the codebase" -> Agent deletes everything.
**Instead**: Scope to "Fix lint errors in THIS file".

### ❌ Trusting Agent Outputs

**Why bad**: LLMs hallucinate success. "I fixed the bug" (Code is still broken).
**Instead**: Always verify with a tool. Run the linter/test. If it fails, reject the agent's claim.

### ❌ General-Purpose Autonomy

**Why bad**: "AGI" style agents get stuck in infinite loops.
**Instead**: Build specialized agents. A "Refactoring Agent" is different from a "Research Agent".

## ⚠️ Sharp Edges

| Issue | Severity | Solution |
|-------|----------|----------|
| Issue | Severity | Solution |
|-------|----------|----------|
| **Infinite Loops** | Critical | Max iteration limits (e.g., 10 steps max). |
| **Cost Spikes** | Critical | Hard budget limit per run (e.g., $1.00). |
| **Hallucinated Tools** | High | Strict tool schemas + validation. |
| **Context Context** | High | Summarize history after N steps. |
| **Credential Leak** | Critical | Regex scan output for secrets before executing. |

## 🛡️ Production Patterns

### Self-Healing Loop (The "Try-Reflect-Retry" Pattern)

**Don't just crash. Recover.**

```python
for attempt in range(3):
    try:
        # 1. Plan & Act
        action = agent.decide(task)
        result = tools.execute(action)
        
        # 2. Verify
        if not verify_success(result):
            raise AgentError("Verification failed")
            
        break # Success!
        
    except Exception as e:
        # 3. Reflect
        print(f"Attempt {attempt} failed: {e}")
        # Feed error back into context so agent knows NOT to do that again
        agent.memory.add(f"Error: {e}. Try a different approach.")
```

### Cost Guardrails

**Kill switch for runaway agents.**

```python
class BudgetKeeper:
    def __init__(self, max_cost=2.00):
        self.total_cost = 0.0
        self.max_cost = max_cost

    def check(self, usage):
        cost = calculate_cost(usage) # Token math
        self.total_cost += cost
        if self.total_cost > self.max_cost:
            raise BudgetExceededError(f"Spent ${self.total_cost}, limit ${self.max_cost}")
```
