Is the Python Services skill free?

Yes. The skill itself is free from iliaal/whetstone. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Python Services SkillProof Score?

9.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 5/5.

How do I install Python Services?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Python Services with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Note the repo actually ships two versions of this content: a raw distillery/generated-skills/python-services scraped from other people's repos (build artifact, not the real skill), and the real plugins/whetstone/skills/ia-python-services with its own references/ folder — tested the real one. On a webhook-retry background-job task it correctly pulled in idempotency keys and a dead-letter queue that a from-memory baseline answer skipped.

What Python Services does

A language-class skill bundled in the Whetstone plugin covering modern Python tooling (uv/ruff/ty), async-vs-sync decisions, FastAPI service structure, Celery background jobs with idempotency, tenacity retries, and structlog/OpenTelemetry observability. It auto-attaches on Python files (paths: **/*.py) and triggers on CLI/FastAPI/async/background-job/uv-ruff-ty language in the prompt.

How to install Python Services

git clone https://github.com/iliaal/whetstone
cd whetstone
mkdir -p ~/.claude/skills
cp -r plugins/whetstone/skills/ia-python-services ~/.claude/skills/python-services

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Python Services

/python-services Opinionated Python patterns for CLI tools, async, FastAPI, jobs and observability.

It also activates on plain-language prompts like these:

Add a background job that retries failed webhooks with backoff
Build a FastAPI endpoint that reports background job status
Help me structure this Python service with proper observability
