jobs.yamlin the current directory - Find the specified job by name
- Set all environment variables from the job's
envsection - Execute the job's command with the proper environment
List available jobs
steve ls
Shows all jobs in jobs.yaml with their commands, schedules, dependencies, and environment variables.

Use custom jobs file
steve -f path/to/custom.yaml extract-data
steve ls -f path/to/custom.yaml
Example
Given a jobs.yaml file:
jobs:
- name: extract-data
cron: "0 2 * * *"
command: ["uv", "run", "src/extract.py"]
env:
SOURCE_URL: "https://jsonplaceholder.typicode.com/users"
OUTPUT_PATH: "/data/raw/extracted_data.parquet"
- name: transform-data
dependsOn: ["extract-data"]
command: ["uv", "run", "src/transform.py"]
env:
INPUT_PATH: "/data/raw/extracted_data.parquet"
OUTPUT_PATH: "/data/processed"
Running steve extract-data will:
- Set
SOURCE_URL=https://jsonplaceholder.typicode.com/users - Set
OUTPUT_PATH=/data/raw/extracted_data.parquet - Execute:
uv run src/extract.py

steve <job-name>to run any job - ✅ Environment: Automatically sets environment variables from
jobs.yaml - ✅ Discovery: Auto-finds
jobs.yamlin current directory - ✅ Listing: See all available jobs with
steve ls - ✅ Flexible: Supports custom jobs file paths

File Metadata Extraction
Steve automatically extracts metadata from files read or written via MetadataRegistry. The extractor is chosen by file extension — no configuration needed.
| Extension | Extractor | Requires |
|---|---|---|
.parquet, .pq |
ParquetExtractor |
pip install steve-cli[polars] |
.csv, .tsv, .txt |
CsvExtractor |
stdlib only |
.json, .jsonl, .ndjson |
JsonExtractor |
stdlib only |
.xlsx, .xls, .xlsm |
ExcelExtractor |
pip install steve-cli[excel] |
| anything else | GenericExtractor |
stdlib only |
Adding a custom extractor
Implement MetadataExtractorPort, declare which extensions it handles, and register it once at startup:
from steve_cli.storage.metadata.port import MetadataExtractorPort, FileMetadata, ColumnMetadata
from steve_cli.storage.metadata.registry import MetadataRegistry
class AvroExtractor(MetadataExtractorPort):
extensions = (".avro",)
def extract(self, data: bytes, path: str) -> FileMetadata:
import fastavro, io
reader = fastavro.reader(io.BytesIO(data))
schema = reader.writer_schema
columns = [
ColumnMetadata(name=f["name"], type=str(f["type"]))
for f in schema.get("fields", [])
]
records = list(reader)
return FileMetadata(
format="avro",
size_bytes=len(data),
rows=len(records),
columns=columns,
)
MetadataRegistry.register("avro", AvroExtractor)
After registration, MetadataRegistry.extract(data, "output.avro") picks AvroExtractor automatically. You can also force a specific extractor for any file via the env var:
METADATA_EXTRACTOR=avro steve jobs run my-job
Why Steve?
Named after Steve Jobs - because it helps you run jobs locally! 😄
