scaffold

scaffold is a skill for Claude Code from Open-Agent-Tools/General-OAT-Skills. It costs 72 tokens per session (1,014 once invoked), scanned A, original, Apache-2.0.

A project starter that creates a new codebase from templates for languages and agent frameworks such as Python, Node.js, Rust, Go, and several AI frameworks.

In plain words
What is it for?
Use it to bootstrap libraries, command-line tools, web apps, data projects, and projects built with supported AI agent frameworks.
Why use it?
It removes the repetitive setup work involved in creating folders, dependency configuration, tests, documentation, and delivery automation.

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 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 9d 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.

What it actually says

Create a new project using the specified template: $ARGUMENTS

Output Format: Use clear section headers, timestamps for each step, and progress indicators for setup operations.

Tool Validation: First verify that required tools are installed (git, uv, gh) and the target directory is valid.

Python Project Defaults: All Python projects use UV for virtual environment management and package installation. Never use pip, pipenv, or conda.

Template Options:

  • python-lib - Python library with pyproject.toml, tests, CI/CD
  • python-cli - Python CLI application with Click/Typer
  • python-web - FastAPI web application
  • python-data - Data science project with Jupyter notebooks
  • python-langchain - LangChain agent project with LangGraph support
  • python-adk - Google Agent Development Kit multi-agent system
  • python-crewai - CrewAI multi-agent orchestration framework
  • python-autogen - Microsoft AutoGen conversational agents
  • python-swarm - OpenAI Swarm lightweight agent framework
  • python-phidata - Phidata AI assistant framework
  • python-llama-index - LlamaIndex RAG agents with document indexing
  • python-haystack - Deepset Haystack NLP pipelines
  • python-semantic-kernel - Microsoft Semantic Kernel plugin architecture
  • python-agency-swarm - Agency Swarm hierarchical agent framework
  • node-lib - Node.js library with TypeScript
  • node-web - React/Next.js web application
  • rust-lib - Rust library with Cargo.toml
  • go-cli - Go CLI application
  • custom - Interactive template selection

Template Loading: Read the template definition from ${CLAUDE_SKILL_DIR}/templates/<template-name>.md for the selected template's directory structure and dependencies.

Project Setup Steps:

  1. Template Selection: Determine template from argument or prompt interactively
  2. Load Template: Read the template file from ${CLAUDE_SKILL_DIR}/templates/<template-name>.md
  3. Directory Creation: Create project directory with proper naming conventions
  4. Template Scaffolding: Create the directory structure and files defined in the template
  5. Dependency Management:
    • For Python: Use uv init and uv add exclusively for all dependencies
    • For Python: Create virtual environment with uv venv and activate with uv run
    • For other languages: Install language-specific dependencies
  6. Git Initialization: Initialize repo, create .gitignore, initial commit
  7. CI/CD Setup: Create GitHub Actions workflows, testing and linting pipelines
  8. Development Environment: Setup IDE config files, development scripts
  9. Documentation: Generate README, CONTRIBUTING.md, documentation framework
  10. Testing Framework: Setup test directory, sample tests, configure runners
  11. Quality Tools: Configure linting, formatters, type checking
  12. Final Validation:
    • For Python: Run uv run python -m pytest and uv build
    • For other languages: Run initial build/compile and basic tests

Interactive Prompts:

  • Project name (default: directory name)
  • Author name and email
  • License type (MIT, Apache, etc.)
  • Description
  • Python version (for Python projects)

Template Variables:

  • {{PROJECT_NAME}} - Project name
  • {{AUTHOR_NAME}} - Author name
  • {{AUTHOR_EMAIL}} - Author email
  • {{DESCRIPTION}} - Project description
  • {{LICENSE}} - License type
  • {{YEAR}} - Current year
  • {{PYTHON_VERSION}} - Python version

Error Handling: If any step fails, attempt to fix the issue automatically. If unable to fix, report the specific error and provide cleanup instructions.

Post-Setup Instructions:

  • Display next steps for development
  • Show available commands (test, build, etc.)
  • Provide quick start guide
  • Suggest development workflow

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.
