 ## [Unreleased]
 
+## [0.3.3] - 2026-05-20
+
+### Added
+
+- Added generated tool reference documentation in `docs/TOOLS.md`.
+- Added `docs:generate` and `docs:check` scripts to keep tool counts, profiles, categories, and descriptions synchronized with `lib/tool-registry.js`.
+- Added CI and release validation for generated tool documentation.
+- Added a read-only `GET /tools` debug endpoint with curl examples for quick local troubleshooting.
+- Added panel activity previews for recent tool calls and runtime logs.
+- Added panel curl copy actions for `/health` and `/tools`.
+
+### Changed
+
+- Refined tool category inference so `get_tool_catalog` is grouped with project/context tools.
+- Updated the MCP client config panel so the preview follows the selected client target.
+- Split file-system tools and asset refresh helpers into `lib/tools/files.js` as the first registry modularization step.
+
+## [0.3.2] - 2026-05-20
+
+### Added
+
+- Added an npm-installable `funplay-cocos-mcp` stdio wrapper that bridges MCP clients to the local Cocos HTTP endpoint.
+- Added MCP Registry metadata in `server.json`, including npm package ownership metadata via `mcpName`.
+- Added wrapper tests, npm pack dry-run verification, and registry validation scripts.
+
+## [0.3.1] - 2026-05-20
+
+### Added
+
+- Added a documented release workflow and release checklist for Cocos extension publishing.
+- Added release packaging scripts that generate a Cocos extension zip, release manifest, checksum file, and per-release README.
+- Added CI validation for release metadata.
+
+## [0.3.0] - 2026-05-20
+
+### Added
+
+- Added MCP `outputSchema` and `annotations` to listed tools.
+- Added a standard structured tool result envelope with `ok`, `tool`, `callId`, `summary`, `data`, and follow-up `refs`.
+- Added prefab workflow tools: `inspect_prefab`, `validate_prefab_references`, `duplicate_prefab`, `edit_prefab_json`, `create_prefab_instance`, `inspect_prefab_instance`, `apply_prefab_instance`, and `revert_prefab_instance`.
+- Added `get_performance_snapshot` and expanded `validate_scene` with scene scale/performance-oriented counters.
+- Added project AI instruction tools: `list_project_instructions`, `read_project_instruction`, `write_project_instruction`, and `create_project_skill`.
+- Added tests for tool metadata, result envelopes, and project instruction helpers.
+
+### Changed
+
+- Expanded the default `core` profile from 28 tools to 34 tools.
+- Expanded the `full` profile from 76 tools to 89 tools.
+- Updated tool interaction logs to store concise result summaries from the standard envelope.

+# 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
+- npm stdio wrapper package
+- Official MCP Registry
+
+## 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`
+- npm package id: `funplay-cocos-mcp`
+- npm command: `funplay-cocos-mcp`
+- MCP Registry server name: `io.github.FunplayAI/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`
+- `server.json` top-level version
+- `server.json` npm package version
+
+Example:
+
+- `package.json`: `0.3.1`
+- Git tag: `v0.3.1`
+- GitHub Release: `v0.3.1`
+- Release asset: `Funplay.CocosMcp.v0.3.1.zip`
+- npm package: `funplay-cocos-mcp@0.3.1`
+- MCP Registry: `0.3.1`
+
+## Files To Update For A New Release
+
+Update:
+
+1. `package.json`
+   - `"version": "<version>"`
+2. `CHANGELOG.md`
+   - add a dated release notes block
+3. `server.json`
+   - top-level `"version"`
+   - npm package `"version"`
+4. `docs/TOOLS.md`
+   - regenerate with `npm run docs:generate` after tool registry changes
+
+Optional but recommended:
+
+5. `README.md`
+6. `README_CN.md`
+7. 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
+- generated tool documentation validation
+- release metadata validation
+- npm package dry-run 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
+```
+
+### 4.5 Validate npm And MCP Registry Metadata
+
+```bash
+npm run pack:dry-run
+npm run registry:validate
+```
+
+The npm package must include the stdio wrapper command:
+
+```bash
+npx --yes ./funplay-cocos-mcp-<version>.tgz --version
+```
+
+### 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. Publish To npm
+
+```bash
+npm publish
+```
+
+Verify the published package:
+
+```bash
+npm view funplay-cocos-mcp@<version> version bin mcpName
+```
+
+Notes:
+
+- `package.json` `mcpName` must match `server.json` `name`.
+- If `npm publish` returns `ENEEDAUTH`, run `npm adduser` with a publishing account and retry.
+- If the package name already exists under another owner, choose a scoped package name and update both `package.json` and `server.json`.
+
+### 9. Publish To MCP Registry
+
+Log in if needed:
+
+```bash
+mcp-publisher login github
+```
+
+Publish:
+
+```bash
+mcp-publisher publish server.json
+```
+
+Verify latest:
+
+```bash
+curl "https://registry.modelcontextprotocol.io/v0.1/servers?search=io.github.FunplayAI/funplay-cocos-mcp&version=latest"
+```
+
+Check a specific version:
+
+```bash
+curl "https://registry.modelcontextprotocol.io/v0.1/servers/io.github.FunplayAI%2Ffunplay-cocos-mcp/versions/<version>"
+```
+
+### 10. 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`.
+8. Install the npm wrapper with `npm install -g funplay-cocos-mcp`.
+9. Connect an MCP client through the `funplay-cocos-mcp` command and call `tools/list`.
+
+## Current Verification Commands
+
+```bash
+npm run release:verify
+npm run registry:validate
+gh release view v<version> -R FunplayAI/funplay-cocos-mcp --json url,assets
+npm view funplay-cocos-mcp@<version> version bin mcpName
+```
+
+## 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>`.
+
+### npm `ENEEDAUTH`
+
+Cause:
+
+- The local machine is not logged in to npm.
+
+Fix:
+
+```bash
+npm adduser
+npm publish
+```
+
+### MCP Registry `Package validation failed`
+
+Cause:
+
+- npm package has not been published yet.
+- `package.json` `mcpName` does not match `server.json` `name`.
+- `server.json` package version does not match the npm package version.
+
+Fix:
+
+- Publish the npm package first.
+- Rerun `npm run release:check`.
+- Rerun `npm run registry:validate`.
