Agent Teams

This tutorial introduces the Claude Managed Agents API by walking through a practical debugging workflow where an agent iteratively fixes failing tests in a Python package. It covers the three core resources (Agent, Environment, Session), file mounting, and the streaming event loop pattern. The example demonstrates how agents autonomously discover the iterate-observe-fix loop by running tests, reading failures, editing code, and repeating until all assertions pass.

This cookbook demonstrates building a Slack data analyst bot using Claude Managed Agents and Bolt for Python. Users mention the bot with a CSV file to receive narrative analysis reports in-thread, with support for multi-turn follow-ups within the same session. The implementation handles file uploads, streams agent progress updates, and manages session persistence across Slack threads.

crewAI 1.14.1rc1 introduces async checkpoint TUI browser and streaming output enhancements, along with critical security updates and architectural improvements. Key changes include CVE-2026-1839 resolution via transformers bump, dynamic tool field exclusion, and refactored provider architecture using BaseModel discriminators. The release focuses on async/streaming capabilities, security hardening, and code quality improvements across the framework.

crewAI 1.14.1 introduces async checkpoint TUI browser functionality and improves streaming output handling with async context managers. The release includes critical security updates (CVE-2026-1839 fix via transformers bump), bug fixes for checkpoint registration and tool name sanitization, and architectural refactoring to use dynamic field exclusion and shared singleton patterns. Key improvements enhance developer experience through better CLI tooling and provider type discrimination.

crewAI v1.14.2a1 is a patch release addressing critical security and event handling issues. Key improvements include fixing the flow_finished event emission after HITL (Human-In-The-Loop) resume operations, upgrading cryptography to version 46.0.7 to patch CVE-2026-39892, and refactoring to use a shared I18N_DEFAULT singleton for better internationalization management.

crewAI 1.14.0 introduces checkpoint management with CLI commands and SqliteProvider storage, implements runtime state checkpointing with an event system, and refactors the executor. Security enhancements include SSRF/path traversal protections and RAG tool validation. The release also optimizes memory serialization by excluding embedding vectors and addresses critical CVE-2026-35030 via litellm upgrade.

The Claude Agent SDK provides built-in session management functions to build conversation history sidebars without writing custom parsers. This cookbook demonstrates how to list, read, rename, tag, and fork sessions stored as JSONL transcripts on disk. By leveraging SDK primitives like list_sessions(), get_session_messages(), and rename_session(), developers can implement session browsers for desktop apps, IDE extensions, and chatbots without managing file I/O directly.

This cookbook demonstrates building a Claude-powered threat intelligence enrichment agent that autonomously investigates Indicators of Compromise (IOCs) by querying multiple threat intel sources, correlating findings, mapping to MITRE ATT&CK, and generating structured reports for SIEM/SOAR integration. The agent uses Claude's tool-use capabilities to decide which intelligence sources to query, chain tool calls based on discoveries, and convert free-text analysis into analyst-ready JSON reports. The architecture uses simulated threat intel backends that can be swapped with real APIs (VirusTotal, AbuseIPDB, Shodan, etc.) without changing orchestration logic.

crewAI 1.14.0a4 introduces checkpoint storage capabilities with SqliteProvider and CheckpointConfig, implements runtime state checkpointing with an event system, and refactors the executor. Key improvements include guardrail tracing enhancements, embedding vector exclusion from memory serialization to reduce token usage, and a security bump to litellm. The release also deprecates CodeInterpreterTool and code execution parameters while improving documentation and performance with JSONB storage.

CrewAI v1.13.0 introduces significant architectural improvements including RuntimeState RootModel for unified serialization, enhanced event telemetry for skills and memory, and A2UI extension support. The release includes critical bug fixes for GPT-5.x model compatibility, RBAC permission alignment, and Windows lancedb compatibility. Performance optimizations reduce framework overhead through lazy event bus implementation and conditional tracing.

crewAI v1.13.0a7 is a minor alpha release introducing A2UI extension support for v0.8/v0.9 with comprehensive schemas and documentation. The release includes bug fixes for multimodal vision prefixes by adding GPT-5 and o-series model support. This update enhances the framework's UI capabilities and model compatibility for advanced vision tasks.
