# @suaveplan/validation

Runtime schema validation with a Zod-compatible API. This package is a self-contained parse engine — it does not import Zod or any other validation library — so it is safe to use in environments where Zod is absent or where bundle size is a constraint. It covers the full schema surface expected from a production validator: all primitive and composite types, `parse`/`safeParse`/`parseAsync`, `refine` (sync + async), `transform`, `describe`, object shape builders (`pick`, `omit`, `partial`, `extend`, `merge`), three unknown-key modes, async lifecycle hooks, and composable helpers (`pipe`, `mergeResults`). Structured errors surface via `@suaveplan/error` with stable `VALIDATION.*` codes. When Zod is already a project dependency and you need its ecosystem (inference helpers, plugins), use Zod directly; use this package for internal platform code and zero-dep environments.

## When to use this skill

- Implementing or debugging code that imports `@suaveplan/validation`.
- The task touches: see package README.
- You need API guidance for this package's exports.

## Quick reference

```ts
import { /* see API Reference below */ } from "@suaveplan/validation";
```

## Dependencies

Workspace dependencies: `@suaveplan/error`, `@suaveplan/events`, `@suaveplan/types`

## Where to read more

This skill is intentionally short. The package's own documentation is the authoritative source — read these in order:

1. **`packages/foundation/validation/README.md`** — overview, install, quick-start, module index
2. **`packages/foundation/validation/src/**/*.md`** — co-located docs per implementation file (Purpose, Features, Basic + Advanced examples, full API reference, Implementation notes — all packages  ship ≥200 words per module)
3. **`packages/foundation/validation/package.json`** `exports` map — every subpath you can import from

When the user asks an API question, read the relevant co-located `.md` first; do not answer from training-data memory.
