Skill Lab52

Installation#

sklab is the CLI that ships with the skill-lab PyPI package. It runs the same static checks and LLM judge as the hosted API — but locally, against a skill directory on your machine. Python 3.10 or newer is required.

Install#

bash
$ pip install skill-lab

Or with uv:

bash
$ uv pip install skill-lab

Verify#

bash
$ sklab --version

Running sklab on its own scans the current directory for SKILL.md files and prints a getting-started guide.

API Keys#

Most commands run without any credentials — check, scan, info, list-checks, prompt, stats, and setup. LLM-powered commands — evaluate (judge step), generate, trigger, and optimize — need an API key:

ProviderEnv varModel prefix
AnthropicANTHROPIC_API_KEYclaude-*
OpenAIOPENAI_API_KEYgpt-*
GoogleGEMINI_API_KEYgemini-*

Provider is auto-detected from the model prefix passed to --model. Keys are read from the environment, a .env file in the current directory, or any standard shell-profile setup. The default model is claude-haiku-4-5-20251001 (Anthropic).

Trigger Testing Prerequisite#

sklab trigger drives a live LLM runtime. The default runtime uses the Claude CLI:

bash
$ npm install -g @anthropic-ai/claude-code

For container isolation (sklab trigger --provider docker), Docker must be installed and running.
