README
# letmediff `letmediff` is a review handoff tool for agent-driven coding sessions. The CLI runs as an MCP server inside a local repository, captures the current worktree diff, and posts it to the web app. The web app renders the diff at a shareable URL and sends reviewer feedback back to the MCP client over server-sent events. ## Workspace This repository is a pnpm monorepo. - `packages/letmediff` contains the `letmediff` MCP CLI. - `apps/letmediff.it` contains the SvelteKit app that stores, renders, and streams diff feedback. ## Requirements - Node.js compatible with the package dependencies - pnpm `^11.2.2` ## Install ```sh pnpm install ``` ## Local Development Run the app: ```sh pnpm --filter letmediff.it dev ``` Run the MCP server against the local app by setting `URL`: ```sh URL=http://localhost:5173 pnpm --filter letmediff exec letmediff ``` When used by an MCP-compatible agent, the server exposes tools to create named checkpoints, create a hosted diff URL, and wait for reviewer feedback. ## How It Works 1. The MCP server snapshots the repository when it starts. 2. The agent can create named checkpoints while it works. 3. When a review URL is requested, the server sends the collected checkpoint diffs to the app. 4. The app renders `/diff/[id]` and keeps an `/events/[id]` SSE connection open. 5. Submitted feedback is streamed back to the MCP server so the agent can continue from the review notes. ## Package READMEs - CLI: [`packages/letmediff/README.md`](packages/letmediff/README.md) - App: [`apps/letmediff.it/README.md`](apps/letmediff.it/README.md)
