human-skill-tree

by 24kchengYe · 24kchengYe/human-skill-tree

33 learning skills from K-12 through career — turns Claude into a tutor that uses spaced repetition, active recall, and Socratic dialogue instead of just answering.

A skill collection for structured lifelong learning. Rather than giving direct answers (which research shows reduces skill acquisition), these 33 skills enforce pedagogical guardrails: spaced repetition, active recall, Socratic questions, and formative assessment. Covers K-12 subjects, university courses, research skills, career skills, and social intelligence across 800+ subjects and 15 education systems.

Use Cases

Real-world ways to use human-skill-tree

Prep for a high-school calc exam without getting answers spoon-fed

👤 High school and early-college students ⏱ ~45 min beginner

When to use: You have two weeks before an exam and want to actually learn the material.

Flow
  1. Start a study session
    Use the human-skill-tree math skill. Quiz me on derivatives — start with what I already know, then push me.✓ Copied
    → Diagnostic question before instruction; answers withheld until I try
  2. Spaced review
    End of session — schedule my next review.✓ Copied
    → Spaced repetition schedule with specific topics

Outcome: Actual skill acquisition, not homework speedruns.

Pitfalls
  • Student pushes for direct answers — The skill's design resists this; if you short-circuit it you lose the benefit
Combine with: tutor-skill

Build a career skill (e.g. negotiation) through Socratic dialogue

👤 Early- to mid-career professionals ⏱ ~30 min intermediate

When to use: You want depth in a soft skill, not another article recap.

Flow
  1. Pick a target skill
    Use the negotiation skill. I want to get better at salary negotiation.✓ Copied
    → Skill opens with a diagnostic scenario
  2. Role-play
    Let's run a scenario — you're the hiring manager, I'm the candidate.✓ Copied
    → Pressure-tested role play with post-debrief

Outcome: Rehearsed responses you can bring to a real negotiation.

Pitfalls
  • Role play too easy — Tell the skill to increase difficulty — harder counteroffers, more pushback

Combinations

Pair with other MCPs for X10 leverage

human-skill-tree-skill + tutor-skill

Pair with tutor-skill's Obsidian study vaults for persistent notes

Use human-skill-tree for the dialogue, tutor-skill to save notes into my Obsidian vault.✓ Copied
human-skill-tree-skill + filesystem

Store progress logs for each subject

Save today's session summary and spaced-rep schedule under ~/learning/calc/.✓ Copied

Security

Permissions, secrets, blast radius

Credential storage: No credentials — skill is prompts
Data egress: None

Troubleshooting

Common errors and fixes

Skill gives direct answers when asked to quiz

Explicitly say 'pedagogical mode — withhold answers until I try'.

Drills feel repetitive

Ask for interleaved practice across related topics, not blocked on one.
