# Maple

Hands a coding agent the review comments pinned to a live preview: it reads the context, edits the code and closes the note with a commit.

## What it does

Maple gathers reviewer notes left on a running frontend, and this server passes them to the agent. The agent waits for a new comment, gets its anchor `file:line`, viewport, screenshot and the mock it was written under, makes the edit, then resolves the comment against the fixing commit. Reviewers stay in the overlay; both sides meet in the store.

Install the package with `npm install @maple-kit/mcp`. You get two binaries: `maple-mcp` for the server and `maple-stop-hook`, which blocks an agent from declaring itself done while comments remain open. Clients start the server with no arguments, so configuration lives in environment variables. The `github` store needs `GITHUB_TOKEN` with read and write access to pull-request comments plus `MAPLE_GITHUB_OWNER` and `MAPLE_GITHUB_REPO`. A missing value fails at startup instead of on the first tool call.

With no forge, comments are read from and written to `.maple/` in the working directory, which keeps the loop usable on a laptop without a pull request. That store is meant for a local machine, not a preview pod. Every package is 0.x with no compatibility promise, so pin it if the workflow matters to your team. `wait_for_comments` caps at 55 seconds because clients cut a call at 60, and a timeout counts as a result — agents that treat it as an error stop looping the moment nobody is watching.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `GITHUB_TOKEN`, `MAPLE_GITHUB_OWNER`, `MAPLE_GITHUB_REPO`, `MAPLE_STORE` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## When to use it
- read a review comment together with its file and line anchor
- wait for the next comment instead of polling the page by hand
- resolve a comment and record the commit that fixed it
- run the review loop on a laptop without a pull request
- keep an agent from finishing while comments are still open

## Example prompts
- List the open review comments on branch `feature/cart`
- Wait for a new comment, then fix what it points at
- Resolve that comment and record the commit sha
