Powerdrill Data Analysis Skill

Analyze data using the Powerdrill API via the Python client at scripts/powerdrill_client.py. All operations use the Powerdrill REST API v2 (https://ai.data.cloud/api).

Prerequisites & Setup

Before using any Powerdrill functions, the user must have:

1. A Powerdrill Teamspace - Created by following: https://www.youtube.com/watch?v=I-0yGD9HeDw
2. API Credentials - Obtained by following: https://www.youtube.com/watch?v=qs-GsUgjb1g

Set these environment variables before running any script:

export POWERDRILL_USER_ID="your_user_id"
export POWERDRILL_PROJECT_API_KEY="your_project_api_key"

The only Python dependency is requests. Install with: pip install requests

If a call fails with an authentication error, verify the two environment variables are set and the API key is valid.

How to Use

Import the client module and call functions directly. All functions read credentials from the environment automatically.

import sys
sys.path.insert(0, "/absolute/path/to/scripts")  # adjust to actual location
from powerdrill_client import *

Or run via CLI:

python scripts/powerdrill_client.py <command> [args]

Available Functions

Datasets

list_datasets(page_number=1, page_size=10, search=None) -> dict

List datasets in the user's account. Typically the first step in any workflow.

result = list_datasets(search="sales")
for ds in result["data"]["records"]:
    print(ds["id"], ds["name"])

create_dataset(name, description="") -> dict

Create a new empty dataset. Returns {"data": {"id": "dset-..."}}.

ds = create_dataset("Q4 Sales Data", "Quarterly sales analysis")
dataset_id = ds["data"]["id"]

get_dataset_overview(dataset_id) -> dict

Get dataset summary, exploration questions, and keywords. Use after data sources are synced.

overview = get_dataset_overview(dataset_id)
print(overview["data"]["summary"])
for q in overview["data"]["exploration_questions"]:
    print(f"  - {q}")

get_dataset_status(dataset_id) -> dict

Check how many data sources are synced/syncing/invalid.

status = get_dataset_status(dataset_id)
# status["data"] = {"synched_count": 3, "synching_count": 0, "invalid_count": 0}

delete_dataset(dataset_id) -> dict

Permanently delete a dataset and all its data sources. Irreversible - always confirm with the user first.

Data Sources

list_data_sources(dataset_id, page_number=1, page_size=10, status=None) -> dict

List files within a dataset. Filter by status: synched, synching, invalid.

sources = list_data_sources(dataset_id, status="synched")

create_data_source(dataset_id, name, *, url=None, file_object_key=None) -> dict

Create a data source from a public URL or an uploaded file key. Provide exactly one of url or file_object_key.

# From public URL
ds = create_data_source(dataset_id, "report.pdf", url="https://example.com/report.pdf")

# From uploaded file (see upload_local_file)
ds = create_data_source(dataset_id, "data.csv", file_object_key=key)

upload_local_file(file_path) -> str

Upload a local file via multipart upload. Returns file_object_key for use with create_data_source().

Supported formats: .csv, .tsv, .md, .mdx, .json, .txt, .pdf, .pptx, .docx, .xls, .xlsx

upload_and_create_data_source(dataset_id, file_path) -> dict

Convenience function: uploads a local file then creates the data source in one call.

result = upload_and_create_data_source(dataset_id, "/path/to/sales.csv")
datasource_id = result["data"]["id"]

wait_for_dataset_sync(dataset_id, max_attempts=30, delay_seconds=3.0) -> dict

Poll until all data sources in the dataset are synced. Raises RuntimeError on timeout or if invalid sources are detected.

upload_and_create_data_source(dataset_id, "data.csv")
wait_for_dataset_sync(dataset_id)  # blocks until synced

Sessions

create_session(name, output_language="AUTO", job_mode="AUTO", max_contextual_job_history=10) -> dict

Create an analysis session. Required before running jobs.

session = create_session("Sales Analysis Session")
session_id = session["data"]["id"]

list_sessions(page_number=1, page_size=10, search=None) -> dict

List existing sessions. Use to find a previous session for resumption.

delete_session(session_id) -> dict

Delete a session. Use during cleanup after analysis is complete.

Jobs (Data Analysis)

create_job(session_id, question, dataset_id=None, datasource_ids=None, stream=False, output_language="AUTO", job_mode="AUTO") -> dict

Run a natural-language analysis query. This is the core analysis function.

Non-streaming (default): returns full response with all blocks.

result = create_job(session_id, "What are the top 5 products by revenue?", dataset_id=dataset_id)
for block in result["data"]["blocks"]:
    if block["type"] == "MESSAGE":
        print(block["content"])
    elif block["type"] == "TABLE":
        print(f"Table: {block['content']['url']}")
    elif block["type"] == "IMAGE":
        print(f"Chart: {block['content']['url']}")

Streaming: returns parsed result with accumulated text and separate blocks.

result = create_job(session_id, "Summarize trends", dataset_id=dataset_id, stream=True)
print(result["text"])        # accumulated MESSAGE text
for b in result["blocks"]:   # TABLE, IMAGE, etc.
    print(b["type"], b["content"])

Response block types:

• MESSAGE - Analytical text
• CODE - Code snippets (Markdown)
• TABLE - {name, url, expires_at} - download before expiration
• IMAGE - {name, url, expires_at} - download before expiration
• SOURCES - Citation references
• QUESTIONS - Suggested follow-up questions
• CHART_INFO - Chart configuration and data

Cleanup

cleanup(session_id=None, dataset_id=None) -> None

Delete session and/or dataset after analysis. Always call this when done.

cleanup(session_id=session_id, dataset_id=dataset_id)

cleanup_session(session_id) -> None / cleanup_dataset(dataset_id) -> None

Delete individual resources. Errors are logged but not raised.

Recommended Workflows

Full analysis workflow (upload, analyze, cleanup)

from powerdrill_client import *

# 1. Create dataset and upload data
ds = create_dataset("My Analysis")
dataset_id = ds["data"]["id"]

upload_and_create_data_source(dataset_id, "/path/to/data.csv")
wait_for_dataset_sync(dataset_id)

# 2. Create session and run analysis
session = create_session("Analysis Session")
session_id = session["data"]["id"]

result = create_job(session_id, "What are the key trends?", dataset_id=dataset_id)
for block in result["data"]["blocks"]:
    if block["type"] == "MESSAGE":
        print(block["content"])

# 3. Ask follow-up questions (same session for context)
result = create_job(session_id, "Break this down by region", dataset_id=dataset_id)

# 4. Cleanup when done
cleanup(session_id=session_id, dataset_id=dataset_id)

Analyze existing dataset

from powerdrill_client import *

# 1. Find the dataset
datasets = list_datasets(search="sales")
dataset_id = datasets["data"]["records"][0]["id"]

# 2. Explore it
overview = get_dataset_overview(dataset_id)
print(overview["data"]["summary"])

# 3. Create session and analyze
session = create_session("Quick Analysis")
session_id = session["data"]["id"]

result = create_job(session_id, overview["data"]["exploration_questions"][0], dataset_id=dataset_id)

# 4. Cleanup session when done (keep dataset)
cleanup_session(session_id)

CLI usage

# List datasets
python scripts/powerdrill_client.py list-datasets --search "sales"

# Create dataset + upload file
python scripts/powerdrill_client.py create-dataset "Test Data"
python scripts/powerdrill_client.py upload-file dset-xxx /path/to/file.csv
python scripts/powerdrill_client.py wait-sync dset-xxx

# Create session and run a job
python scripts/powerdrill_client.py create-session "My Session"
python scripts/powerdrill_client.py create-job SESSION_ID "Summarize the data" --dataset-id dset-xxx

# Cleanup
python scripts/powerdrill_client.py cleanup --session-id SESSION_ID --dataset-id dset-xxx

Error Handling

• Authentication errors: Verify POWERDRILL_USER_ID and POWERDRILL_PROJECT_API_KEY. Direct the user to the setup videos above.
• Dataset not found: Re-run list_datasets() to verify the ID. The dataset may have been deleted.
• Job execution failure: Ensure the dataset has at least one synced data source (wait_for_dataset_sync()). Retry with a rephrased question.
• Upload timeout: wait_for_dataset_sync() polls up to 30 attempts (90s). Use get_dataset_status() to check manually.
• Invalid data sources: Check file format is supported. Re-upload with correct file type.
• Rate limiting: Wait before retrying. Space out rapid sequential API calls.

Important Notes

• Always create a session before running analysis jobs
• Always call cleanup() to delete sessions and datasets after analysis is complete
• Sessions maintain conversational context - reuse the same session for related follow-up questions
• TABLE and IMAGE URLs in job responses expire - download or present results promptly
• Call wait_for_dataset_sync() after uploading files, before running analysis
• Dataset and session names are limited to 128 characters
• Supported file formats: .csv, .tsv, .md, .mdx, .json, .txt, .pdf, .pptx, .docx, .xls, .xlsx
