# Lassare

Lassare routes an AI coding agent’s questions and approval requests to Slack, so you can answer from a phone while the agent keeps running.

## What it does

Lassare is an MCP server for Claude Code, Codex, Cursor, Gemini CLI and other compatible clients. Its `ask` tool sends a clarification request to Slack, while `approve` presents an approval or denial action for a risky step. The agent receives the reply and carries on.

The package includes hooks for supported agents. They can keep work moving between questions, intercept commands such as `rm -rf`, `git push --force` and `sudo`, and ask one more question before the agent stops. The intercepted-command list lives in `permission-approve.sh`. Unanswered questions and approvals expire after 15 minutes.

Setup requires a Lassare account, a connected Slack workspace and an API key from Agent Setup. Configuration is copied into the project by hand. Use `/lassare-slack` for remote questions or `/lassare-inline` for questions in the current conversation. Without a connected Slack workspace, remote replies have nowhere to go.
