Creates Python projects with proper structure, virtual environments, and dependency management.

  • Works in 5 steps: Understand Requirements → Create Project Structure → Virtual Environment Setup → …
  • Users request to create a new Python project
  • SKILL.md covers Critical Corrections, Overview, Project Creation Workflow and Project Types, plus 5 more sections
  • Runs Python scripts from its folder; calls uv, python3 and git

What it does

Python Project Creator is an agent skill from haddock-development/claude-reflect-system. Creates Python projects with proper structure, virtual environments, and dependency management. Use when users request to create a new Python project, set up a Python development environment, or initialize a Python application with standard tooling.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts, reference files and assets (for example `references/api_reference.md` and `scripts/example.py`).

It sits in Development, covering Dependency management, Unit testing and Linting and formatting. It works with Python and pytest. The repository describes itself as: Continual Learning & Self-improving skills system for Claude Code - learn from corrections, never repeat mistakes.

When your agent uses it

  • Users request to create a new Python project
  • Set up a Python development environment
  • Initialize a Python application with standard tooling

Example prompts

  • “Use the python-project-creator skill to create Python projects with proper structure, virtual environments, and dependency management”
  • “/python-project-creator”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Understand Requirements
  2. Create Project Structure
  3. Virtual Environment Setup
  4. Install Dependencies
  5. Initialize Git

What it can do on your machine

Read from SKILL.md and the folder at commit 41d03d0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • uv
    • python3
    • git
    • pytest
    • black
    • mypy

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use uv and git, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Python Project Creator loads about 1.4k tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 68 tokens; SKILL.md has 372 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~68
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 372 words (~1,448 tokens).
