# 0.2.1 — 2026-04-04

## Changed

- Renamed tool exports for consistency: `lookupCalendarTool` → `lookupCalendar`, `lookupElectionsTool` → `lookupElections`, `searchLegalTool` → `searchLegal`.
- `FecParams` type now supports `string[]` values for repeated query parameters (e.g., multiple `candidate_id` values).
- `search-candidates` tool sends multi-candidate totals lookups as repeated query params instead of comma-separated strings.
- Calendar tool `report_type` parameter scoped to filing deadlines mode only; added dedicated `category` parameter for calendar category filtering in events mode.
- Disbursements tool `committee_id` enforced as required via `.min(1)` schema constraint instead of runtime guard.

## Added

- Shared `utils/format-helpers.ts` — extracted `fmt$`, `str`, and `PaginationSchema` from duplicated inline definitions across tools.
- Shared `utils/id-validators.ts` — extracted `validateCandidateId` and `validateCommitteeId` with consistent error messages.
- Contributions tool now validates `candidate_id` and `committee_id` format before API calls.
