Why it matters
An open-source desktop agent can continue tasks started in Claude Code or Codex with an open-weight model and share sessions with the CLI and extension, lowering switching cost between harnesses.

Cline Desktop lets you assign different models to Plan and Act, run local models, or bring your own key for 50+ providers, alongside 300+ models through the Cline provider.
The Schedule feature runs cron-style agent jobs where you set prompt, workspace, provider, model and frequency; Cline says it uses these for a morning PR review, a nightly repo check and weekly documentation updates.

Terms in this piece · Glossary
agent harness — The scaffolding around a model that turns it into a working agent — the loop, the tools it can call, and the rules for when to stop.
agentic loop — The cycle an agent runs in: decide, call a tool, read the result, decide again — repeating until the goal is met or a stop condition fires.
context window — The maximum amount of text a model can consider at once — its working memory for the current conversation or task.
attention — The mechanism that lets a model weigh which earlier words matter for the word it's currently processing — the core operation of a transformer.
