# Palantir Local Dev Loop ## Overview Set up local development for Palantir Foundry integrations. Covers running transforms locally against sample data, mocking the Foundry API for fast iteration, and testing with pytest before pushing to Foundry. ## Prerequisites - Completed `palantir-install-auth` setup - Python 3.9+ with pip - A Foundry Code Repository cloned locally (or a standalone project) ## Instructions ### Step 1: Project Structure ``` my-foundry-project/ ├── src/myproject/ │ ├── __init__.py │ ├── pipeline.py # @transform functions │ └── utils.py # Shared logic ├── tests/ │ ├── conftest.py # Fixtures with sample DataFrames │ ├── test_pipeline.py # Transform unit tests │ └── sample_data/ # CSV/Parquet test fixtures ├── .env # FOUNDRY_HOSTNAME, FOUNDRY_TOKEN ├── requirements.txt # foundry-platform-sdk, pytest, pyspark └── pyproject.toml ``` ### Step 2: Install Local Dependencies ```bash set -euo pipefail pip install foundry-platform-sdk pyspark pytest pandas python -c "import foundry; import pyspark; print('Dependencies ready')" ``` ### Step 3: Test Transforms Locally with PySpark ```python # tests/conftest.py import pytest from pyspark.sql import SparkSession @pytest.fixtur

How do I install it?
Run `npx skills add jeremylongshore/claude-code-plugins-plus-skills --skill palantir-local-dev-loop --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From jeremylongshore/claude-code-plugins-plus-skills, a repository with 2,630 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
