# Tasks — Add @suaveplan/currency-provider-coingecko

## Spec-completeness preflight (AGENTS.md §12a)

- [x] Numbered checklist of every `### Requirement` and `#### Scenario`
      drafted in `specs/currency-provider-coingecko/spec.md` (7
      requirements added; see the spec delta).

## Package scaffolding

- [x] Create `packages/finance/currency-provider-coingecko/` directory tree
- [x] `package.json` — `0.1.0`, universal-tier, `sideEffects: false`,
      subpath exports for the feature modules, deps via `workspace:^` and
      `catalog:`
- [x] `tsconfig.json`, `tsconfig.lib.json`
- [x] `vite.config.ts` (build), `vitest.config.ts` (test + 100/100/100/100)
- [x] `tests/setup/polyfills.ts`
- [x] `README.md`

## Implementation

- [x] `src/coin-ids/coin-ids.ts` — curated symbol → CoinGecko-ID map +
      `getCoinGeckoId()` lookup
- [x] `src/coin-ids/coin-ids.md` — sibling doc, ≥200 words
- [x] `src/coin-ids/coin-ids.test.ts` — full coverage of the lookup
- [x] `src/coin-ids/index.ts` — explicit named barrel
- [x] `src/coingecko/coingecko.ts` — `CoinGeckoProvider` class
- [x] `src/coingecko/coingecko.md` — sibling doc, ≥200 words
- [x] `src/coingecko/coingecko.test.ts` — keyless + Pro-key branches +
      every `CurrencyProviderError` code path
- [x] `src/coingecko/index.ts` — explicit named barrel
- [x] `src/index.ts` — explicit named root barrel

## Verification

- [x] `bunx turbo lint typecheck test --filter=@suaveplan/currency-provider-coingecko`
- [x] `bunx turbo test:coverage --filter=@suaveplan/currency-provider-coingecko`
      at 100/100/100/100
- [x] `bunx turbo build --filter=@suaveplan/currency-provider-coingecko`
- [x] Banned-pattern scan zero
- [x] Barrel-shape scan zero (no `export *` in feature barrels)
- [x] Test-runner import scan zero (every test goes through
      `@suaveplan/testing/runner`)
- [x] Missing `.md` scan zero
- [x] `README.md` present

## Repo-doc refresh (AGENTS.md §13b)

- [x] Add `currency-provider-coingecko` to
      `scripts/folder-reorg/assignment.yml` under the finance group
- [x] `bun scripts/folder-reorg/generate-manifest.ts` → refresh
      `MANIFEST.md`
- [x] `bun scripts/generate-missing.ts` → refresh `MISSING.yml`
- [x] Update `STATUS.md` with a row for the new package
- [x] Update `SUMMARY.md` per-package paragraph
- [x] `bunx markdownlint-cli2 --fix` clean

## Archive

- [x] Fold `specs/currency-provider-coingecko/spec.md` into
      `openspec/specs/currency-provider-coingecko/spec.md`
- [x] Move `openspec/changes/add-currency-provider-coingecko/` →
      `openspec/archive/2026-05-17-add-currency-provider-coingecko/`
