## Crates for [problem]

| Crate | Downloads | Updated | Deps |
|-------|-----------|---------|------|
| `foo` | 10M/month | 2025-01 | 3 |
| `bar` | 500K/month | 2024-12 | 12 |

### `foo`
- Pros: Fast, minimal deps, good docs
- Cons: Less flexible API

### `bar`
- Pros: Feature-rich, active community
- Cons: Heavy dependency tree

**Recommendation:** `foo` - balances simplicity and capability

Add `foo` to Cargo.toml?

4. Wait for User Approval

Never add dependency without explicit user confirmation.

Quick Evaluation

For known-good crates, check version only:

bash
cargo search serde --limit 1
