Skills

Skills are structured documentation “packs” injected into prompts to improve answer quality in specific domains (Spec2, Roassal, Collections, Bloc, etc.).

How skills work

A skill is a subclass of ChatPharoSkill with:

• name (unique ID)
• description
• keywords (for matching)
• contextString (the injected documentation)

Skills are discovered by scanning subclasses and are managed by ChatPharoSkillRegistry.

Manual skills

Manually enabled skills are always injected as:

### ENABLED SKILLS CONTEXT ###
<skill context...>

Automatic skill detection

If enabled, ChatPharo extracts keywords from the current query and injects matching skills that are marked as auto-enabled:

### AUTO-DETECTED SKILLS CONTEXT ###
(Based on detected keywords: ...)
<skill context...>

Skill tools

When skillToolsEnabled is enabled, the model can call tools such as:

• list_available_skills
• get_skill_context

This lets the model request specialized docs on demand.

Included skills (examples)

• ChatPharo help skill (how to use ChatPharo)
• Roassal (visualization)
• Spec2 (UI)
• Collections (core library)
• Bloc (low-level UI)

Adding a new skill (developer)

1. Create a new subclass of ChatPharoSkill.
2. Implement name, description, keywords, and contextString.
3. Refresh the skills list in settings (or reset the registry).
