Agent Harness
Serious engineering
under every agent.
VectorLumira’s harness runs your agents: context management, tool routing, retries, parallel tool calls, memory and sandboxed execution, tuned so the same agent performs well across models.
The engine under every agent.
What you get with Agent Harness.
Context engineering
Automatic compaction, retrieval and summarization keep long tasks within the model’s window.
Tool routing
Large toolsets are searched and loaded on demand, so agents with thousands of tools stay fast and accurate.
Durable execution
Long-running agents survive restarts and resume exactly where they left off.
Sandboxed code
Agents can write and run code in isolated sandboxes with files and network policies.
Human in the loop
Pause for approval, ask a clarifying question, or hand off to a person, then continue.
Model-agnostic
Prompting and tool formats are adapted per provider so you don’t have to.
Questions
Can I customize the harness?+
Yes. Tune context limits, retry policies, parallelism and approval rules per agent.
