+# PR Label Sync
+
+This directory contains scripts and sample data for automatically classifying and labeling GitHub Pull Requests based on the files they modify.
+
+## Files
+
+- `index.js`: The main Node.js script. It fetches PR files, evaluates their risk level, calculates business impact, and uses GitHub APIs to add appropriate `size/*` and `area/*` labels.
+- `samples.json`: A collection of historical PRs used as test cases to verify the labeling logic (especially for regression testing the S/M/L thresholds).
+
+## Features
+
+### Size Labels (`size/*`)
+The script evaluates the "effective" lines of code changed (ignoring tests, docs, and ci files) to classify the PR:
+- **`size/S`**: Low-risk changes involving only docs, tests, CI workflows, or chores.
+- **`size/M`**: Small-to-medium changes affecting a single business domain, with effective lines under 300.
+- **`size/L`**: Large features (>= 300 lines), cross-domain changes, or any changes touching core architecture paths (like `cmd/`).
+- **`size/XL`**: Architectural overhauls, extremely large PRs (>1200 lines), or sensitive refactors.
+
+### Area Tags (`area/*`)
+The script also identifies which high-level architectural modules a PR touches to give reviewers an immediate sense of the impact scope. Currently tracked important areas include:
+- `area/cmd`
+- `area/shortcuts`
+- `area/skills`
+
+Minor modules like docs and tests are omitted to keep PR tags clean and focused on structural changes.
+
+## Usage
+
+### In GitHub Actions
+This script is designed to run in CI workflows. It automatically reads the `GITHUB_EVENT_PATH` payload to get the PR context.
+
+```bash
+node scripts/pr-labels/index.js
+```
+
+### Local Dry Run
+You can test the labeling logic against an existing GitHub PR without actually applying labels by using the `--dry-run` flag.
+
+```bash
+# Requires GITHUB_TOKEN environment variable or passing --token
+node scripts/pr-labels/index.js --dry-run --repo larksuite/cli --pr-number 123
+```
+
+To see the raw JSON output for programmatic use:
+```bash
+node scripts/pr-labels/index.js --dry-run --repo larksuite/cli --pr-number 123 --json
+```
