Your agents,
under control.
Run Claude Code, Codex, and any supported agent in isolated workspaces with a full record of everything they did.
One balance.
Every model.
No API keys. No five separate subscriptions. Buy credits once, use them across every model K3 supports.

Every attempt
in its own world.
Run experiments safely. Each agent executes in an isolated environment scoped strictly to its workspace. Nothing bleeds between them.
The work
survives you.
Step away without starting over. The full timeline is tracked. Pick up months or days later, exactly where the agent left off. No lost context, no re-explaining.

Nothing destructive
runs without you.
The permission gate acts as a calm, transparent wall. Approve or reject file edits and commands. You control the scope of access.
Your agent.
Not ours.
Switch models mid-conversation without breaking context. Plug in external agents via the workspace configuration registry.

Skills
Write once. Every agent picks it up. Custom command configurations are mapped as global skills instantly.
Personas
Roles on demand. Define tone, expertise, and guardrails once. Swap personas across threads without starting over.
Hooks
Your scripts. Your rules. Attach pre-run validation checks before agents issue commits or modify staging areas.
MCP
External tools. No rewiring. Fully compatible with any Model Context Protocol servers natively.
Built for how software gets made now.
