Qwen3 agent harness
problem
an agent with many tools burns its context window on schemas and old turns before it does any work.
what I built
- a Qwen3 32B agent harness with network-isolated code execution
- LLM-based context compaction, and deduplicated tool schemas
- document VLM and RAG ingest tools, and a benchmark of Qwen3-VL 32B and Qwen2.5-VL 72B
results
- deduplicating tool schemas cut the fixed per-call cost 45% (9.2k to 5.0k tokens)
- 85% of a 32k context window stays free
