Frequently Asked Questions about mentat-skill

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I evaluate the effectiveness of a mentat skill?▼

To evaluate a mentat skill, run functional and cognitive evaluations against the skill using the eval command. This process scores the skill's performance while guarding results with pass-rate and token-ratio gates.

How do I scaffold a new skill from a template?▼

You can scaffold a new skill by generating a skill directory from pre-configured templates. This creates the necessary directory structure and configuration files required to start developing a new mentat skill.

What is skill shrinkage and how does it optimize SKILL.md files?▼

Skill shrinkage analyzes existing SKILL.md files and proposes leaner versions. It reduces token usage while preserving core functionality, helping parallel coding agents process instructions more efficiently.

Can I manage parallel coding agents and code rebases with this tool?▼

Yes, this tool handles parallel coding agent management with a focus on code rebase, re-gate, scoring, and landing operations. It coordinates multiple agents working simultaneously on the same codebase.

What are pass-rate and token-ratio gates in skill evaluation?▼

Pass-rate and token-ratio gates are threshold metrics used during functional and cognitive evaluations. They determine whether a skill meets performance standards by measuring test success rates and token consumption efficiency.

Do I need any dependencies installed to use mentat-skill?▼

No external dependencies are required to use mentat-skill. It operates independently using its built-in scripts and references components to perform evaluations, shrinkage, and scaffolding tasks.
