BEFORE answering, do the following MANDATORILY:
1. ASSESSMENT: find suitable skills from <available_skills> for the user's request
2. ACTIVATION: call Skill() for each suitable skill.
3. EXECUTION: proceed ONLY after step 2; without calling skills, assessment is useless
Example:
- sample:skill — because X and Y
