+# Release Checklist
+
+Use this checklist before publishing a new release of Funplay MCP for Cocos.
+
+## 1. Repository Hygiene
+
+- [ ] `git status` contains only intended release changes
+- [ ] No tracked local junk is present (`.DS_Store`, `.idea/`, `node_modules/`, `Library/`, `Temp/`, `dist/`, `build/`)
+- [ ] `package.json` version matches the intended release
+- [ ] `CHANGELOG.md` includes the release notes for the target version
+- [ ] `README.md` and `README_CN.md` match the current product behavior
+
+## 2. Automated Verification
+
+- [ ] `npm run check` passes
+- [ ] `npm test` passes
+- [ ] `npm run release:check` passes
+- [ ] `npm run release:package` creates `releases/<version>/`
+- [ ] `shasum -a 256 -c releases/<version>/SHA256SUMS.txt` passes
+
+## 3. Package Contents
+
+- [ ] The zip is named `Funplay.CocosMcp.v<version>.zip`
+- [ ] The zip contains a single top-level `funplay-cocos-mcp/` folder
+- [ ] The zip contains runtime files: `package.json`, `browser.js`, `scene.js`, `panel/`, and `lib/`
+- [ ] The zip includes docs: `README.md`, `README_CN.md`, `CHANGELOG.md`, `CONTRIBUTING.md`, and `LICENSE`
+- [ ] The zip does not contain `.git/`, `.github/`, `.DS_Store`, `node_modules/`, `Library/`, `Temp/`, `dist/`, `build/`, `test/`, or `scripts/`
+- [ ] `release-manifest.json` references the correct GitHub download URL
+- [ ] `SHA256SUMS.txt` includes the zip, manifest, and release README
+
+## 4. Cocos Smoke Test
+
+- [ ] Test in a clean Cocos Creator `3.8+` project
+- [ ] Install from the generated zip into `<project>/extensions/funplay-cocos-mcp`
+- [ ] Restart Cocos Creator or reload extensions
+- [ ] Open `Funplay > MCP Server`
+- [ ] Start the MCP server successfully
+- [ ] If the configured port is already in use, verify automatic fallback is reported clearly
+- [ ] Run a read-only tool such as `get_project_info`
+- [ ] Run a scene inspection tool such as `get_scene_info`
+- [ ] Run a screenshot tool when the editor has a visible scene or preview
+- [ ] Verify interaction logs appear in the MCP Server panel
+
+## 5. MCP Client Verification
+
+- [ ] Verify at least one primary client can connect (`Claude Code`, `Cursor`, `Codex`, etc.)
+- [ ] Confirm `tools/list` returns the expected `core` profile tools
+- [ ] Confirm a tool call succeeds end-to-end from the external client
+- [ ] Verify one-click config output still matches the documented config snippets
+
+## 6. GitHub Release Readiness
+
+- [ ] CI passes on `main`
+- [ ] Release commit message is `Release v<version>`
+- [ ] Tag is `v<version>`
+- [ ] GitHub Release title is `v<version>`
+- [ ] GitHub Release includes the zip, manifest, checksum file, and release README
+- [ ] Public GitHub Release page renders the release notes and assets correctly
+
+## 7. Publish
+
+- [ ] Commit the release changes
+- [ ] Create and push the release tag
+- [ ] Create or update the GitHub Release
+- [ ] Upload generated release assets
+- [ ] Verify the GitHub Release asset list
+
+## 8. Post-Release
+
+- [ ] Re-test installation from the public GitHub Release zip
+- [ ] Check the update checker reports the new latest version
+- [ ] Check README install instructions and download links
+- [ ] Announce the release where appropriate

+# Funplay Cocos MCP Release Workflow
+
+This document records the release workflow for publishing Funplay MCP for Cocos to:
+
+- Git tags
+- GitHub Releases
+- Downloadable Cocos Creator extension zip packages
+
+## Published Identity
+
+- GitHub repository: `https://github.com/FunplayAI/funplay-cocos-mcp`
+- Git tag format: `v<version>`
+- GitHub Release tag: `v<version>`
+- Extension package asset: `Funplay.CocosMcp.v<version>.zip`
+- Cocos extension folder name inside the zip: `funplay-cocos-mcp`
+- Default local MCP endpoint: `http://127.0.0.1:8765/`
+
+## Version Alignment Rule
+
+Keep these versions aligned:
+
+- `package.json` `version`
+- `CHANGELOG.md` release section
+- Git tag `v<version>`
+- GitHub Release `v<version>`
+- `releases/<version>/release-manifest.json` `version`
+- Release zip filename `Funplay.CocosMcp.v<version>.zip`
+
+Example:
+
+- `package.json`: `0.3.1`
+- Git tag: `v0.3.1`
+- GitHub Release: `v0.3.1`
+- Release asset: `Funplay.CocosMcp.v0.3.1.zip`
+
+## Files To Update For A New Release
+
+Update:
+
+1. `package.json`
+   - `"version": "<version>"`
+2. `CHANGELOG.md`
+   - add a dated release notes block
+
+Optional but recommended:
+
+3. `README.md`
+4. `README_CN.md`
+5. GitHub Release notes text
+
+## Release Steps
+
+### 1. Verify Working Tree
+
+```bash
+git status --short --branch
+```
+
+The tree should contain only intentional release changes.
+
+### 2. Update Versions And Notes
+
+Update `package.json` and `CHANGELOG.md`.
+
+Use semantic versions such as `0.3.1`, and keep release headings in this format:
+
+```markdown
+## [0.3.1] - 2026-05-20
+```
+
+### 3. Run Release Verification
+
+```bash
+npm run release:verify
+```
+
+This runs:
+
+- JavaScript syntax checks
+- Node.js tests
+- release metadata validation
+- release package generation
+
+The generated local artifacts are written to:
+
+```text
+releases/<version>/
+```
+
+Expected contents:
+
+- `Funplay.CocosMcp.v<version>.zip`
+- `release-manifest.json`
+- `SHA256SUMS.txt`
+- `README.md`
+
+### 4. Inspect The Package
+
+The release script validates that every archive path stays under:
+
+```text
+funplay-cocos-mcp/
+```
+
+The package must not contain local/build content such as:
+
+- `.git/`
+- `.github/`
+- `.DS_Store`
+- `node_modules/`
+- `Library/`
+- `Temp/`
+- `dist/`
+- `build/`
+- `test/`
+- `scripts/`
+
+Verify checksums:
+
+```bash
+cd releases/<version>
+shasum -a 256 -c SHA256SUMS.txt
+```
+
+### 5. Commit, Tag, And Push
+
+```bash
+git add .
+git commit -m "Release v<version>"
+git tag v<version>
+git push origin main
+git push origin v<version>
+```
+
+### 6. Create GitHub Release
+
+Regenerate the final release artifacts from the tagged clean commit:
+
+```bash
+npm run release:package -- --strict-tag
+```
+
+If creating a new release:
+
+```bash
+gh release create v<version> \
+  -R FunplayAI/funplay-cocos-mcp \
+  --title "v<version>" \
+  --notes-file /path/to/release-notes.md \
+  releases/<version>/Funplay.CocosMcp.v<version>.zip \
+  releases/<version>/release-manifest.json \
+  releases/<version>/SHA256SUMS.txt \
+  releases/<version>/README.md
+```
+
+If the release already exists and only assets need to be replaced:
+
+```bash
+gh release upload v<version> \
+  -R FunplayAI/funplay-cocos-mcp \
+  --clobber \
+  releases/<version>/Funplay.CocosMcp.v<version>.zip \
+  releases/<version>/release-manifest.json \
+  releases/<version>/SHA256SUMS.txt \
+  releases/<version>/README.md
+```
+
+### 7. Verify GitHub Release
+
+```bash
+gh release view v<version> \
+  -R FunplayAI/funplay-cocos-mcp \
+  --json url,assets,isDraft,isPrerelease,publishedAt
+```
+
+Confirm the release has all four assets.
+
+### 8. Post-Release Smoke Test
+
+Test the package from the public GitHub Release:
+
+1. Download `Funplay.CocosMcp.v<version>.zip`.
+2. Unzip it.
+3. Move `funplay-cocos-mcp` into a Cocos project `extensions/` directory.
+4. Restart Cocos Creator or reload extensions.
+5. Open `Funplay > MCP Server`.
+6. Start the MCP server.
+7. Connect an MCP client and call `get_project_info`.
+
+## Current Verification Commands
+
+```bash
+npm run release:verify
+gh release view v<version> -R FunplayAI/funplay-cocos-mcp --json url,assets
+```
+
+## Common Failure Cases
+
+### Release validation says the changelog section is missing
+
+Cause:
+
+- `CHANGELOG.md` does not contain `## [<version>] - YYYY-MM-DD`.
+
+Fix:
+
+- Add a dated release section before packaging.
+
+### `zip` command is missing
+
+Cause:
+
+- The local environment does not have the `zip` CLI installed.
+
+Fix:
+
+- Install `zip`, then rerun `npm run release:package`.
+
+### GitHub Release upload replaces the wrong assets
+
+Cause:
+
+- The version directory or release tag does not match `package.json` version.
+
+Fix:
+
+- Rerun `npm run release:check`.
+- Confirm the command uses `releases/<version>/` and `v<version>`.
