Skills

A skill is a package of structured files that teaches an AI coding agent how to work with a specific tool or framework. The skill below was generated by Great Docs from this project’s documentation. Install it in your agent and it will be able to run commands, edit configuration, write content, and troubleshoot problems without step-by-step guidance from you.

Any agent — install with npx:

npx skills add https://ozanozbeker.com/dagster-dataframely/

Codex / OpenCode

Tell the agent:
Fetch the skill file at https://ozanozbeker.com/dagster-dataframely/skill.md and follow the instructions.

Manual — download the skill file:

curl -O https://ozanozbeker.com/dagster-dataframely/skill.md

# dagster_dataframely

A Dataframely integration for Dagster.

## Installation

```bash
pip install dagster-dataframely
```

## API overview

### Core

`dd.asset` builds an asset from a schema, and `quarantine_spec` adds that asset's quarantine to the asset graph.

- `asset`: Turn the decorated function into an asset that validates the frame it returns against `schema`
- `quarantine_spec`: Return an asset spec that adds an asset's quarantine to the asset graph
- `Granularity`: Type alias
- `SchemaRules`: Type alias

### Hand-wiring

`dd.asset` assembles these parts. Use them to build a `@dg.asset` yourself, where `dd.asset` does not fit.

- `wiring.schema_metadata`
- `wiring.table_schema`
- `wiring.check_specs`
- `wiring.check_results`
- `wiring.check_name`
- `wiring.validation_results`
- `wiring.AssetYield`
- `wiring.QuarantineWriter`
- `wiring.delegating_writer`
- `wiring.file_writer`
- `wiring.quarantine_frame`
- `wiring.quarantine_path`
- `wiring.validate_quarantine_key`

### Errors

This package raises these errors. Each one subclasses `DagsterDataframelyError`.

- `errors.DagsterDataframelyError`
- `errors.CollectionNotSupportedError`
- `errors.ReservedColumnError`
- `errors.InvalidColumnNameError`
- `errors.CheckNameCollisionError`
- `errors.InvalidSettingError`
- `errors.MaterializeResultValueError`
- `errors.MaterializeResultFieldError`
- `errors.ColumnSchemaError`
- `errors.ValidationAbortError`
- `errors.NoValidRowsError`
- `errors.QuarantineKeyCollisionError`
- `errors.QuarantineDirError`
