new-python-project is a skill for Claude Code from smorinlabs/py-launch-blueprint. It costs 49 tokens per session (3,481 once invoked), scanned A, original, MIT.

A setup skill for starting a new Python repository, package, command-line tool, or script from the py-launch-blueprint template. It covers project creation, rebranding, checks, and optionally publishing the initial project to GitHub.

In plain words
What is it for?
Use it when creating a fresh Python project from this template. It is intended for new repositories, not for modifying an existing project.
Why use it?
It guides the setup decisions and catches common problems such as authentication issues or invalid package names before they interrupt the project start.

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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

new-python-project scanned grade A with 1 finding 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 369 lines — stays where its author put it; the contents beside it link to each section on GitHub.

new-python-project

Create a fresh Python project from smorinlabs/py-launch-blueprint, validate its CLI and web application, and deliver the initialization as a pull request. The generated project starts at version 0.1.0 and requires Python 3.13+.

Use this runbook from the original blueprint checkout throughout the bootstrap. Rebranding removes the generated copy of SKILL.md and retires its companion documentation. The generated project's ongoing setup checklist is docs/PROJECT_SETUP.md; docs/POST_INIT.md is a template/provenance pointer.

Scope and authorization

Use this skill for a new project derived from the blueprint. An existing project with press/press-receipt.toml, the record of a completed rebrand, is not a fresh bootstrap target.

If the user has already selected the blueprint or approved this bootstrap, continue without asking them to choose it again. For a generic Python project request where that choice is unresolved, ask whether they want the blueprint's full toolchain or a minimal setup. If they decline the template, leave this skill and follow their chosen approach.

Resolve the GitHub owner, repository name, visibility, and target directory before creating resources. Summarize the identity, local setup, and intended initialization pull request. Ask for approval only if those actions are not already authorized. An approved full bootstrap includes the preview, declared cleanup, rebrand, local toolchain setup, validation, and initialization PR. Publishing packages, merging the PR, and configuring external services require their own requested scope.

Runbook

Run commands from the stated directory and stop at a failed command. Replace angle-bracket placeholders with the collected values. The shell examples use Bash; keep the bootstrap_* variables available between steps. Record their resolved values when the execution tool starts a separate shell for each call.

1. Check prerequisites and collect missing identity

From the original blueprint checkout, verify the command-line tools and GitHub login before creating the new repository:

What this file has done since we first saw it

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.
