SKILL.md

Autonomous Coding Agent Skill

Build complete applications from specification files using a multi-session autonomous agent.

Usage

Invoke with a spec file path:

/auto-code --spec ./path/to/spec.txt

With additional options:

/auto-code --spec ./spec.txt --project-dir ./output --max-iterations 10

How It Works

This skill invokes the auto-code Python package to:

Read your application specification
Create a feature list with 200+ test cases
Implement features one by one with browser-based verification
Continue across sessions until all features pass

Prerequisites

The package must be installed from source:

bash

# Clone and install
git clone https://github.com/AhamSammich/auto-code.git
cd auto-code
pip install -e .

Authentication is required - set one of:

ANTHROPIC_API_KEY - API key from console.anthropic.com
CLAUDE_CODE_OAUTH_TOKEN - OAuth token (run claude setup-token)

Invocation

When this skill is triggered, run the following command:

bash

auto-code --spec <spec_path> --project-dir <project_dir>

Replace <spec_path> with the user's specification file path. Replace <project_dir> with the desired output directory (default: ./autonomous_project).

Arguments

Argument	Required	Description
`--spec`	Yes	Path to the application specification file
`--project-dir`	No	Output directory for the project (default: `./autonomous_project`)
`--max-iterations`	No	Maximum agent iterations (default: unlimited)
`--model`	No	Claude model to use (default: `claude-sonnet-4-5-20250929`)

Security

The agent runs in a sandboxed environment with:

Filesystem access restricted to the project directory
Bash commands limited to a safe allowlist
No ability to modify security settings
