pragmatiks-sdk 0.9.0

Python SDK for the Pragmatiks platform

Pragma SDK

Documentation | CLI | Providers

Build providers and interact with the pragma-os platform programmatically.

Quick Start

from pragma_sdk import PragmaClient, Resource

with PragmaClient() as client:
    # Apply a resource
    client.apply_resource(
        Resource(
            provider="gcp",
            resource="storage",
            name="my-bucket",
            config={"location": "US", "storage_class": "STANDARD"}
        )
    )

    # Get resource status
    bucket = client.get_resource("gcp", "storage", "my-bucket")
    print(bucket.outputs)

Installation

pip install pragmatiks-sdk

Or with uv:

uv add pragmatiks-sdk

Features

• HTTP Clients - Sync and async clients for the pragma-os API
• Provider Authoring - Build custom providers with type-safe Config and Outputs
• Field References - Reference outputs from other resources dynamically
• Testing Harness - Test provider lifecycle methods locally without deployment
• Auto-discovery - Automatic credential resolution from environment or config files

Building Providers

Define resources with typed configuration and lifecycle methods:

from pragma_sdk import Provider, Resource, Config, Outputs, Field

gcp = Provider(name="gcp")

class BucketConfig(Config):
    location: Field[str]
    storage_class: Field[str] = "STANDARD"

class BucketOutputs(Outputs):
    url: str
    created_at: str

@gcp.resource("storage")
class Bucket(Resource[BucketConfig, BucketOutputs]):
    async def on_create(self) -> BucketOutputs:
        # Provision the bucket
        return BucketOutputs(url=f"gs://{self.name}", created_at="...")

    async def on_update(self, previous_config: BucketConfig) -> BucketOutputs:
        # Handle config changes
        return self.outputs

    async def on_delete(self) -> None:
        # Clean up
        pass

Field References

Reference outputs from other resources:

from pragma_sdk import FieldReference

config = AppConfig(
    database_url=FieldReference(
        provider="postgres",
        resource="database",
        name="my-db",
        field="outputs.connection_url"
    )
)

Testing Providers

Test lifecycle methods locally with ProviderHarness:

from pragma_sdk.provider import ProviderHarness

async def test_bucket_creation():
    harness = ProviderHarness()

    result = await harness.invoke_create(
        Bucket,
        name="test-bucket",
        config=BucketConfig(location="US")
    )

    assert result.success
    assert "gs://test-bucket" in result.outputs.url

Authentication

Credentials are discovered automatically:

1. Explicit auth_token parameter
2. Environment variable: PRAGMA_AUTH_TOKEN
3. Credentials file: ~/.config/pragma/credentials

# Auto-discover credentials
client = PragmaClient()

# Explicit token
client = PragmaClient(auth_token="sk_...")

# Require authentication (fail if no token)
client = PragmaClient(require_auth=True)
