How is DeepSeek Harness different?

“Agent harness” is a broad category. Two tools may both run a model and tools while serving very different users. Compare the shape of the product before comparing feature counts.

Four common product shapes

TokenRoleCheck
DeepSeek HarnessA runnable local workbench assembled as a Cordis plugin treeConfigure profiles, bundles, providers, tools, sessions, and UI plugins
Agent SDKA library used by developers inside their own applicationApplication code defines agents, tools, handoffs, guardrails, and runs
Graph runtimeLow-level orchestration for durable, stateful workflowsDevelopers model nodes, state, persistence, interruption, and resumption
Finished Agent productAn opinionated application ready for a task such as codingUsers primarily configure the product rather than assemble its runtime

The distinctive DSH choice is composition

  • The model adapter, Agent loop, tools, session log, Web service, and UI are all composed plugins rather than a fixed core plus a small add-on API.
  • A profile is a named, ordered plugin composition, so web and headless can share foundations while presenting different products.
  • Registrations are reversible effects tied to plugin lifetime; unloading a plugin can unwind the services or visual overrides it added.
  • The session event stream is the durable source from which history, replay, and UI state are derived.

Choose by the job you need to do

  1. 01

    Identify the primary user

    Is the user a developer building an Agent application, or a person who wants to run and configure an Agent workbench?

  2. 02

    Identify the extension unit

    Do you want Python or TypeScript application code, explicit graph nodes, product settings, or installable plugins and profiles?

  3. 03

    Identify the state model

    Decide whether simple session memory, durable graph checkpoints, or an event-sourced workbench log best matches the task.

  4. 04

    Count operational responsibilities

    A library leaves more UI, deployment, storage, and policy choices to you. A runnable product makes more of those choices before you start.
