Does this skill handle the 'active run' error?

Yes, it includes specific patterns to detect and cancel active runs, preventing the 400 error that occurs when trying to add messages to a busy thread.

Does it support streaming?

Absolutely. It includes patterns for the 'runs.stream' method to handle message deltas, tool progress, and completion events in real-time.

How many files does this skill support for RAG?

The v2 implementation supported by this skill allows for up to 10,000 files per vector store, a significant increase from the 20-file limit in v1.

Can I use this with models like o3-mini or o1?

Yes, it provides specific fixes for reasoning models, such as explicitly clearing temperature and top_p parameters which are unsupported and cause errors in those models.

Is the OpenAI Assistants API deprecated?

Yes, OpenAI has scheduled the sunset of Assistants API v2 for August 26, 2026. This skill is intended for maintaining legacy apps or migration, recommending the Responses API for new projects.

API Development

Implements stateful chatbots using OpenAI Assistants API v2 with built-in fixes for vector stores, memory leaks, and parameter conflicts.

This skill provides specialized guidance and production-ready patterns for building sophisticated AI agents using the OpenAI Assistants API v2. It excels at managing stateful conversation threads, high-capacity file searches (RAG), and sandboxed Python code execution via Code Interpreter. Designed for enterprise-grade stability, it includes critical implementation patterns that bypass 10 documented API bugs, such as vector store upload errors, temperature parameter conflicts with reasoning models, and thread race conditions. While optimized for maintaining and migrating legacy systems, it also provides a clear roadmap for the transition to the Responses API ahead of the 2026 sunset.

Key Features

01Pre-configured workarounds for 10 documented OpenAI SDK bugs and race conditions

02Stateful thread and message management for persistent AI conversations

03Sandboxed Code Interpreter for automated data analysis and chart generation

040 GitHub stars

05High-scale File Search supporting semantic RAG across 10,000 documents

06Real-time event streaming for responsive, low-latency chat interfaces

Use Cases

01Implementing document-heavy RAG systems with automated vector store polling

02Maintaining and troubleshooting legacy enterprise chatbots using Assistants API v2

03Migrating existing v1 Assistant implementations to the v2 standard before the 2026 sunset
