Updating Local Development Agents

Overview

When developing the penguiflow library, changes need to be propagated to test agents in test_generation/. This skill documents the workflow.

Directory Structure

code

penguiflow/
├── penguiflow/           # Library source code
│   ├── tools/
│   │   ├── node.py       # ToolNode implementation
│   │   └── config.py     # ExternalToolConfig, AuthType
│   ├── planner/
│   └── ...
├── test_generation/
│   └── reporting-agent/  # Test agent using local penguiflow
│       ├── src/reporting_agent/
│       ├── pyproject.toml
│       └── .env

Workflow: After Library Changes

1. Make changes to library

Edit files in penguiflow/ (e.g., penguiflow/tools/node.py)

2. Reinstall library in test agent venv

bash

cd test_generation/reporting-agent
uv sync --reinstall-package penguiflow

This rebuilds and reinstalls the local penguiflow into the agent's venv.

3. Test the changes

bash

# Quick test
uv run python -c "from penguiflow.tools import ToolNode; print('OK')"

# Run agent tests
uv run pytest tests/

# Or run the agent directly
uv run penguiflow dev

Common Issues

"VIRTUAL_ENV does not match" Warning

When running from the main penguiflow directory:

code

warning: `VIRTUAL_ENV=/path/to/penguiflow/.venv` does not match the project environment

This is harmless - uv uses the correct venv based on the project.

Import Errors After Changes

If imports fail after library changes:

•Ensure you ran uv sync --reinstall-package penguiflow
•Check for syntax errors in the library code
•Verify the library installs: uv run python -c "import penguiflow"

Type Errors

Run mypy after changes:

bash

cd /path/to/penguiflow
uv run mypy penguiflow

Agent Configuration

pyproject.toml Reference

toml

[project]
dependencies = [
    "penguiflow[planner] @ file:///absolute/path/to/penguiflow",
    # other deps...
]

.env Configuration

Test agents use .env for configuration:

bash

# MCP Server URLs
TABLEAU_MCP_SERVER_URL=https://...
CHARTING_MCP_SERVER_URL=https://...

# Auth credentials
TABLEAU_MCP_COOKIE=<session_cookie>
DATABRICKS_CLIENT_ID=...
DATABRICKS_CLIENT_SECRET=...

Quick Reference Commands

bash

# From test agent directory
cd test_generation/reporting-agent

# Reinstall library
uv sync --reinstall-package penguiflow

# Run tests
uv run pytest tests/ -v

# Run specific test
uv run pytest tests/test_orchestrator.py -k "test_name"

# Interactive testing
uv run python -c "
import asyncio
from reporting_agent.orchestrator import ReportingAgentOrchestrator
# ... test code
"

# Start dev server
uv run penguiflow dev

CI Pipeline

Before committing library changes:

bash

cd /path/to/penguiflow
uv run ruff check penguiflow
uv run mypy penguiflow
uv run pytest --cov=penguiflow
