# 0.3.2 — 2026-04-19

## Changed

- Upgraded `@cyanheads/mcp-ts-core` from 0.2.12 to 0.3.8 and synced 15 project skills; added new `add-app-tool` skill.
- Bumped devDependencies to latest: `@biomejs/biome` 2.4.12, `@types/node` 25.6.0, `typescript` 6.0.3, `vitest` 4.1.4.
- Collapsed `+` string concatenations in all tool and resource descriptions, enum `.describe()` calls, and the itemized-contribution error message to single string literals.
- `candidate.resource.ts` now uses the shared `validateCandidateId()` helper instead of an inline regex check, so invalid candidate IDs surface as `invalidParams` (MCP error `-32602`) instead of a generic `Error`, matching the tool-side behavior.
