Covers transient failure handling, circuit breakers, exponential backoff, state recovery, graceful degradation, and dead-letter queues for agent systems.'\nmetadata:\n author: cosmicstack-labs\n version: 1.0.0\n category: ai-ml\n tags:\n - error-recovery\n - retry-logic\n - circuit-breaker\n - fallback-strategies\n - fault-tolerance\n - graceful-degradation\n---\n\n# Error Recovery & Retry Logic for Agents\n\n## Overview\n\nAgents fail. APIs time out. Models return garbage. Tools throw exceptions. The difference between a production-grade system and a prototype is how gracefully it fails. This skill covers comprehensive error recovery patterns — from simple retries to circuit breakers, stateful recovery, and human escalation paths.\n\n---\n\n## Core Concepts\n\n### Failure Taxonomy\n\n| Failure Type | Example | Frequency | Recoverable? |\n|-------------|---------|-----------|-------------|\n| **Transient** | API timeout, network glitch | Common | ✅ Yes — retry |\n| **Rate Limited** | 429 Too Many Requests | Common | ✅ Yes — backoff |\n| **Validation** | Invalid tool parameters | Occasional | ✅ Yes — fix and retry |\n| **Model Error** | LLM returns nonsense | Occasional | ⚠️ Maybe — retry with different prompt |\n| **Context Overflow** | Token limit exceeded | Rare | ✅ Yes — compress and retry |\n| **Permission** | Agent lacks access | Rare | ❌ No — escalate |\n| **Security** | Injection attempt detected | Rare | ❌ No — alert and block |\n| **Permanent** | Tool deleted, endpoint gone | Rare | ❌ No — escalate to human |\n\n### Recovery Strategy Decision Tree\n\n```\n ┌──────────────┐\n │ Agent Error │\n └──────┬───────┘\n │\n ┌───────────┴───────────┐\n │ │\n Transient? Permanent?\n │ │\n ┌────┴────┐ ┌──────┴──────┐\n │ │ │ │\n Retry Circuit Fallback Escalate\n +backoff Breaker Agent to Human\n```\n\n---\n\n## Step-by-Step Implementation\n\n### Step 1: Retry with Exponential Backoff\n\n```python\nimport asyncio\nimport random\nfrom functools import wraps\nfrom typing import Callable, Any\n\nasync def retry_with_backoff(\n fn: Callable,\n max_retries: int = 3,\n base_delay: float = 1.0,\n max_delay: float = 60.0,\n backoff_factor: float = 2.0,\n jitter: bool = True,\n retryable_exceptions: tuple = (TimeoutError, ConnectionError, \n RateLimitError)\n) -> Any:\n \"\"\"Execute a function with exponential backoff retry logic.\"\"\"\n last_exception = None\n \n for attempt in range(max_retries + 1):\n try:\n return await fn()\n except retryable_exceptions as e:\n last_exception = e\n \n if attempt == max_retries:\n raise # Exhausted retries\n \n # Calculate delay with exponential backoff\n delay = min(base_delay * (backoff_factor ** attempt), max_delay)\n \n # Add jitter to prevent thundering herd\n if jitter:\n delay = delay * (0.5 + random.random() * 0.5)\n \n logger.warning(\n f\"Attempt {attempt + 1}/{max_retries + 1} failed: {e}. \"\n f\"Retrying in {delay:.1f}s...\"\n )\n \n await asyncio.sleep(delay)\n \n raise last_exception # Shouldn't reach here, but safety\n\n\nclass RetryPolicy:\n \"\"\"Configurable retry policy for agent operations.\"\"\"\n \n def __init__(self, name: str, max_retries: int = 3, \n base_delay: float = 1.0, max_delay: float = 60.0,\n backoff_factor: float = 2.0):\n self.name = name\n self.max_retries = max_retries\n self.base_delay = base_delay\n self.max_delay = max_delay\n self.backoff_factor = backoff_factor\n self.consecutive_failures = 0\n \n async def execute(self, fn: Callable) -> Any:\n \"\"\"Execute with this policy's retry configuration.\"\"\"\n try:\n result = await retry_with_backoff(\n fn,\n max_retries=self.max_retries,\n base_delay=self.base_delay,\n max_delay=self.max_delay,\n backoff_factor=self.backoff_factor\n )\n self.consecutive_failures = 0\n return result\n except Exception as e:\n self.consecutive_failures += 1\n raise\n \n def is_circuit_breaking(self, threshold: int = 5) -> bool:\n \"\"\"Check if consecutive failures exceed threshold.\"\"\"\n return self.consecutive_failures >= threshold\n\n# Predefined policies\nRETRY_POLICIES = {\n \"tool_call\": RetryPolicy(\"tool_call\", max_retries=3, base_delay=0.5),\n \"api_request\": RetryPolicy(\"api_request\", max_retries=5, base_delay=1.0),\n \"llm_generation\": RetryPolicy(\"llm_generation\", max_retries=2, base_delay=2.0),\n \"database_query\": RetryPolicy(\"database_query\", max_retries=3, base_delay=0.1),\n}\n```\n\n### Step 2: Circuit Breaker Pattern\n\n```python\nclass CircuitBreaker:\n \"\"\"Prevent repeated calls to failing services.\"\"\"\n \n STATES = [\"CLOSED\", \"OPEN\", \"HALF_OPEN\"]\n \n def __init__(self, name: str, failure_threshold: int = 5,\n recovery_timeout: float = 30.0,\n half_open_max_calls: int = 3):\n self.name = name\n self.failure_threshold = failure_threshold\n self.recovery_timeout = recovery_timeout\n self.half_open_max_calls = half_open_max_calls\n \n self.state = \"CLOSED\"\n self.failure_count = 0\n self.last_failure_time = None\n self.half_open_calls = 0\n \n async def call(self, fn: Callable, fallback: Callable = None) -> Any:\n \"\"\"Execute with circuit breaking.\"\"\"\n \n if self.state == \"OPEN\":\n if self._should_attempt_recovery():\n self.state = \"HALF_OPEN\"\n self.half_open_calls = 0\n else:\n return await self._use_fallback(fn, fallback)\n \n if self.state == \"HALF_OPEN\":\n if self.half_open_calls >= self.half_open_max_calls:\n return await self._use_fallback(fn, fallback)\n self.half_open_calls += 1\n \n try:\n result = await fn()\n self._on_success()\n return result\n except Exception as e:\n self._on_failure(e)\n \n if self.state == \"HALF_OPEN\":\n self.state = \"OPEN\"\n self.last_failure_time = time.time()\n \n return await self._use_fallback(fn, fallback)\n \n def _on_success(self):\n self.failure_count = 0\n if self.state == \"HALF_OPEN\":\n self.state = \"CLOSED\"\n \n def _on_failure(self, error: Exception):\n self.failure_count += 1\n self.last_failure_time = time.time()\n \n if self.failure_count >= self.failure_threshold:\n self.state = \"OPEN\"\n logger.warning(\n f\"Circuit breaker {self.name} OPEN after \"\n f\"{self.failure_count} failures\"\n )\n \n def _should_attempt_recovery(self) -> bool:\n if not self.last_failure_time:\n return True\n elapsed = time.time() -
