Every initiative gets its own chat

Your team and Hamster can now think through an initiative together, not just the briefs under it.

Initiative chat

Ask where an initiative stands, or why it's at risk, and Hamster reasons across the whole tree of briefs and sub-initiatives beneath it.

Learn more about initiatives.

CLI

The CLI now does everything an agent can over MCP, so you can create, read, and update your work from the terminal.

Get started with the CLI, or see the full list of MCP tools.

Improvements

  • A custom MCP client can now be registered to connect to Hamster, even if it can't self-register
  • Cloud agent environments now prefill their setup from what each repository actually uses
  • A connected repository can now index a branch other than its default
  • Cloud deliveries with Codex now run on GPT-5.6 Sol, Terra, and Luna
  • A failed password sign-in now points you to account recovery

Bug Fixes

  • Updating the Hamster CLI on macOS no longer breaks it, and installing no longer needs sudo
  • Hamster now waits and retries when a connected app is rate-limited, and says so while it waits
  • Broad Context Graph searches now stay focused on the most relevant results
  • Cloud deliveries now retry in a fresh environment when the running one becomes unreachable
  • Committed cloud work still reaches the repository when a later delivery step fails
  • A cloud delivery now installs its missing agent plugin instead of stopping partway
  • When Hamster needs clarification, it now opens the questions directly instead of only saying that it will
  • Hamster no longer claims an initiative is linked to a goal that can't hold one, and says which goals can
  • Websites added during onboarding now get more time and more attempts to load, and one that still fails stays in Context with a clear error, ready to retry
  • Editing or deleting a document that's no longer accessible now says so plainly
  • A skill with its title cleared now saves as Untitled
  • Rows in the initiatives and goals lists line up again
  • Renaming a goal, initiative, or blueprint now updates the browser tab title instead of showing the old name
