Your coding agent
>in your terminal
Cosine CLI brings agentic engineering into your shell, 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.
brew install CosineAI/tap/cosBuilt 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.
Todo 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.
