scaffold-python

scaffold-python is a skill for Claude Code from urmzd/dotfiles. It costs 135 tokens per session (1,767 once invoked), scanned A, original, Apache-2.0.

A set of instructions for creating or standardizing a Python project with common development, testing, and release files.

In plain words
What is it for?
Use it when starting a Python CLI, library, or application, or when adding CI/CD and shared project conventions to an existing Python project.
Why use it?
It removes the need to assemble project structure, code checks, continuous integration, and release setup from scratch.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: mentions AGENTS.md.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is uses: ./.github/workflows/ci.yml.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

scaffold-python scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Scaffold Python Project

Generate a production-ready Python project following established CI/CD patterns. Read the scaffold-project skill first for standard files (README, AGENTS.md, LICENSE, CONTRIBUTING.md, llms.txt).

When to Use

  • Creating a new Python CLI, library, or application
  • Adding CI/CD to an existing Python project missing workflows
  • Standardizing a Python project to match org conventions

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
