Use when writing standalone Python scripts (one-off scripts, utilities, not part of a larger Python project with pyproject.toml or setup.py). Provides UV shebang template and best practices.

What this skill does


# Standalone Python Scripts

## UV Shebang Template

For standalone Python scripts, always use the UV shebang format:

```python
#!/usr/bin/env -S uv run --script
#
# /// script
# dependencies = [
#   "requests",
#   "click",
# ]
# [tool.uv]
# exclude-newer = "2025-08-23T00:00:00Z"
# ///

import requests
import click

# Your script code here
```

## Key Points

- **Self-contained:** All dependencies declared in the file
- **No virtual env needed:** UV handles dependencies automatically
- **Execution:** Run directly with `uv run script.py` or `./script.py` (if executable)
- **Date pinning:** The `exclude-newer` ensures reproducible builds
- **PEP 723 compliant:** Uses the inline script metadata standard

## When to Use

✅ **Use this for:**

- One-off automation scripts
- CLI utilities
- Data processing scripts
- Quick prototypes
- Scripts without a containing project

❌ **Don't use this for:**

- Files in a project with `pyproject.toml` or `setup.py`
- Modules meant to be imported
- Production services/applications

## Example Script

```python
#!/usr/bin/env -S uv run --script
#
# /// script
# dependencies = [
#   "httpx",
#   "rich",
# ]
# [tool.uv]
# exclude-newer = "2025-08-23T00:00:00Z"
# ///

import httpx
from rich import print

def main():
    response = httpx.get("https://api.github.com")
    print(f"Status: {response.status_code}")

if __name__ == "__main__":
    main()
```

## Making Scripts Executable

```bash
chmod +x script.py
./script.py  # Run directly
```

jax-development

Included

Use this skill when the user is writing, debugging, profiling, refactoring, reviewing, benchmarking, parallelising, exporting, or explaining JAX code, or when they mention JAX, jax.numpy, jit, grad, value_and_grad, vmap, scan, lax, random keys, pytrees, jax.Array, sharding, Mesh, PartitionSpec, NamedSharding, pmap, shard_map, Pallas, XLA, StableHLO, checkify, profiler, or the JAX repo. It helps turn NumPy or PyTorch-style code into pure functional JAX, fix tracer/control-flow/shape/PRNG bugs, remove recompiles and host-device syncs, choose transforms and sharding strategies, inspect jaxpr/lowering/IR, and benchmark compiled code correctly.

Writing & Docsscripts

nature-article-writer

Included

Drafts, rewrites, diagnostically critiques, and style-calibrates primary research manuscripts for Nature and Nature Portfolio journals. Use when the user wants a Nature-style title, summary paragraph or abstract, introduction, results, discussion, methods, figure legends, presubmission enquiry, cover letter, reviewer response, or when a scientific draft sounds generic, jargon-heavy, structurally weak, or AI-ish and needs precise, broad-reader-friendly prose without inventing data, analyses, or references. Best for primary research articles and letters rather than reviews or press releases unless explicitly adapting one.

Writing & Docsscripts

deckrd

Included

Document-driven framework that derives requirements, specifications, implementation plans, and executable tasks from goals through structured AI dialogue. Use when user says "write requirements", "create spec", "plan implementation", "derive tasks", "structure this feature", "break down into tasks", or "document this module". Also use for reverse engineering existing code into docs (/deckrd rev). Do NOT use for direct code writing — use /deckrd-coder after tasks are generated. Do NOT use when the user only wants to run or fix existing code without planning.

Writing & Docsscripts

clinical-decision-support

Included

Generate professional clinical decision support (CDS) documents for pharmaceutical and clinical research settings, including patient cohort analyses (biomarker-stratified with outcomes) and treatment recommendation reports (evidence-based guidelines with decision algorithms). Supports GRADE evidence grading, statistical analysis (hazard ratios, survival curves, waterfall plots), biomarker integration, and regulatory compliance. Outputs publication-ready LaTeX/PDF format optimized for drug development, clinical research, and evidence synthesis.

Writing & Docsscripts

handling-sf-data

Included

Salesforce data operations with 130-point scoring. Use this skill to create, update, delete, bulk import/export, generate test data, and clean up org records using sf CLI and anonymous Apex. TRIGGER when: user creates test data, performs bulk import/export, uses sf data CLI commands, needs data factory patterns for Apex tests, or needs to seed/clean records in a Salesforce org. DO NOT TRIGGER when: SOQL query writing only (use querying-soql), Apex test execution (use running-apex-tests), or metadata deployment (use deploying-metadata).

Writing & Docsscripts

accelint-ac-to-playwright

Included

Convert and validate acceptance criteria for Playwright test automation. Use when user asks to (1) review/evaluate/check if AC are ready for automation, (2) assess if AC can be converted as-is, (3) validate AC quality for Playwright, (4) turn AC into tests, (5) generate tests from acceptance criteria, (6) convert .md bullets or .feature Gherkin files to Playwright specs, (7) create test automation from requirements. Handles both bullet-style markdown and Gherkin syntax with JSON test plan generation and validation.
