v0.17.1

⚠️ BREAKING CHANGES ⚠️

sunpeak's best-in-class MCP App inspector and testing engine now works with any arbitrary MCP server, not only sunpeak projects!

Breaking Changes in v0.17.0

1. Removed exports from sunpeak/simulator and sunpeak/chatgpt

The following functions and types have been deleted and are no longer available:

Removed export	Type
buildDevSimulations	function
buildSimulations	function
buildResourceMap	function
createResourceExports	function
BuildSimulationsOptions	type
BuildDevSimulationsOptions	type
ResourceMetadata	type

These were previously importable from sunpeak, sunpeak/simulator, or sunpeak/chatgpt. They are no longer needed because sunpeak dev now discovers tools/resources/simulations via MCP protocol instead of Vite globs.

2. Deleted template files

If you scaffolded a project with sunpeak new, these files in your project are now dead code and should be deleted:

• .sunpeak/dev.tsx
• .sunpeak/resource-loader.html
• .sunpeak/resource-loader.tsx
• index.html (root)
• src/resources/index.ts

3. Tool annotations are now explicit

Tool files should specify all three annotation hints explicitly:

- annotations: { readOnlyHint: true },
+ annotations: { readOnlyHint: true, destructiveHint: false, openWorldHint: false },

This is non-breaking at runtime but your tests may fail if they assert on annotations.

---

Upgrade Instructions

1. Update sunpeak:

   pnpm update sunpeak@^0.17.0

2. Delete obsolete files from your project root:

   rm -rf .sunpeak/ index.html src/resources/index.ts

3. Remove dead imports — if you imported any of the removed functions (buildDevSimulations, buildSimulations, buildResourceMap, createResourceExports), delete those imports. They are no longer needed; sunpeak dev handles simulation discovery automatically via MCP.

4. Update tool annotations — add explicit destructiveHint and openWorldHint to each tool's annotations object and update any test assertions accordingly.

5. Run validation:

   pnpm validate
