Your agent already knows what to build.
Your agent doesn't just get a task description. It gets the brief, the reasoning, the team's decisions, and the acceptance criteria — synced into your repo as markdown files in real time.
Auth Feature
Compatibility and optionality
One Hamster, any CLI, IDE, or model.
When your briefs, plans, and tasks live inside a vendor's tool, switching costs are brutal. A better model drops and you're stuck — or you start over.
Hamster is the central repository of work, not the model. Briefs and plans stay in one place. The agent is interchangeable. Use Claude for deep reasoning, Gemini for speed, an open-weight model for sensitive code — or a different model for every task on the board.
New frontier model ships on Tuesday? Point it at your .hamster/ directory and keep going.
MCP
Agents write back too.
The Hamster MCP server gives your agent 39 tools to update task status, create subtasks, link initiatives, and read plans — directly from the coding session. When the agent finishes a task, it updates the plan. No one has to do it manually.
Install
Install it where you already work.
Add the plugin and your agent can read your Briefs, Tasks, and Blueprints from the first prompt. Your client signs you in through the browser once, and the plugin does the rest.
Claude Code
/plugin marketplace add gethamster/cli
/plugin install hamster@hamster-pluginsCursor
Not on the Cursor marketplace yet. Import it from GitHub with the steps in the setup guide.
Codex
codex plugin marketplace add gethamster/cli
codex plugin add hamster@hamster-pluginsAntigravity
agy plugin install https://github.com/gethamster/cliInstall Hamster
Add the plugin in the AI coding tool you already use. Sign-in and the connection to Hamster come with it.
Run setup
Run the setup skill. It installs the CLI, signs it in, and connects this repo to your team.
Work normally
Open your coding agent. The context files are already there. Ask it to build something — it knows what that means.
Advanced: install the CLI on its own
Most people don't need this. If you want the hamster binary without the plugin, install it and initialize your repo by hand.
curl -fsSL https://tryhamster.com/cli/install | bashKey capabilities
The full brief, not just a title
The difference between "implement auth" and a brief with the strategy, constraints, compliance requirements, and team decisions. Your agent gets the latter.
39 MCP tools built in
Update task status, create subtasks, link initiatives — all from the coding session.
Works offline
Context files are local. Your agent reads them even without a network connection.
Any MCP-compatible agent
One server, every tool. Claude Code, Cursor, Gemini CLI, Codex, and more.
Skill file generation
The CLI generates structured project maps so your agent understands the full codebase.
No new workflow
You don't pull context in. It's just there. Work the way you already work.
Wire your agent into the plan.
