DeepSeekHarness Open-Sourced: Code-Orchestrating Agent Framework In-Depth
AGI Hunt · wechat · 2026-08-13
An in-depth look at DeepSeekHarness (powered by the Cordis meta-framework), an open-source agent framework focused on "spatiotemporal composability". It modularizes models, tools, and storage as plugins.
Key Highlights:
- Programmatic Tool Calling (PTC): Instead of single-turn tool calls, the model generates code to orchestrate multi-turn tool executions. Intermediate data stays in the environment, with only final results injected into the context.
- Self-Bootstrapping: In creative mode, the agent can dynamically test and install plugins for itself during runtime.
- Append-Only Event Stream: Session logs never delete original history during context compression, enabling full traceability, forking, and replay.
- Concurrent Agents: A two-tier configuration allows multiple agents with distinct toolsets to run in parallel within the same process.
