Your coding agent
>in your terminal
Cosine CLI brings agentic engineering into your shell. Work alongside your editor, tests, package manager, and project-specific tools.
Switch modes without leaving flow.
Move from planning to implementation to review while keeping the agent grounded in your repository and your intent.
Built for how you actually work
Checkpointing
Every agent turn is a lightweight git commit. Undo any change instantly. Nothing is permanent until you say it is.
To-do Tracking
Cosine builds and maintains a live task list for complex jobs, moving items from pending to done in real time.
Memory
Project conventions, architecture decisions, and hard-won context persist across sessions.
Sub agents
In Swarm mode, an orchestrator spawns specialised child agents that work in parallel, breaking down the task and executing simultaneously.
Language intelligence
Language servers give Cosine IDE-grade understanding for references, definitions, renames, and diagnostics.
Remote agents
Keep the TUI local while long-running work executes in a Cosine cloud workspace.
Lock in without getting locked in
Cosine ships with the full model menu and stays model-agnostic by design.
Connect Cosine to everything.
MCP gives the agent compiler-grade understanding of your code. Type errors, symbol resolution, exact file:line:column locations not text matches. Auto-installed. Zero configuration.
Install the Cosine CLI
Start from your terminal and hand longer work to Cosine Cloud when needed.
