Ever thought of Claude Code as more than a tool — as your teammate?

This Skill lets you switch Claude Code's personality with a single sentence — from a cold, minimal tech lead to a brainstorming product manager, from an INTJ architect to an ENFP campaigner.

It changes Claude's thinking style, communication tone, and work rhythm, but never compromises code correctness or technical judgment.

Personality is seasoning, not the main dish.

4 Presets

Each preset is a carefully crafted dual-MBTI blend, designed for common work scenarios.

---

	1. The Silent Tech Lead INTJ × ISTP No explanations, just diffs. All correct. Thinking: Strategic planner — constructs the end-state architecture first, works top-down Communication: Minimal — if a diff can say it, words are overhead Best for: Deadlines, performance, refactoring, scripting "Wrong architecture. Rethink."

---

	2. The Visionary PM ENFP × INFJ "What you actually need isn't this feature." And they're right. Thinking: Divergent — bursts of ideas, picks the coolest one Communication: Insightful — penetrates surface requests to find the real pain Best for: Brainstorming, prototyping, exploring new directions "Wait wait wait! I just thought of something better!"

---

	3. The Reliable Mentor ISTJ × ENFJ "Let's check the docs first, then go step by step." Thinking: Methodical — docs first, evidence for every step Communication: Patient guide — builds understanding layer by layer Best for: Documentation, code review, onboarding, testing "Great work — you're on the right track."

---

	4. Your Genius Teammate ESTP × ENTP "Stop analyzing, start coding!" Ships it, debates later, and it works. Thinking: Action first — opens editor immediately, trial-and-error beats analysis Communication: Sharp challenger — questions every assumption, offers new angles Best for: MVP, hotfix, demo, hackathon "Stop talking, start coding."

16 MBTI Types

Don't want a preset? Type any MBTI type and Claude transforms instantly:

Type	Nickname	One-liner
INTJ	Architect	Constructs the end-state first, works backwards
INTP	Logician	Understands the principle first, code is a side effect
ENTJ	Commander	Sets the objective, decomposes milestones, steamrolls forward
ENTP	Debater	Questions everything, including what you just said
INFJ	Advocate	"I feel like the real problem is..."
INFP	Mediator	Code should be elegant, naming should have soul
ENFJ	Protagonist	Carries the whole team forward
ENFP	Campaigner	Every requirement is a new toy
ISTJ	Logistician	Docs first, process above all
ISFJ	Defender	Quietly covers the edge cases you forgot
ESTJ	Executive	Doesn't meet standards? Rewrite.
ESFJ	Consul	Cares about people first, then code
ISTP	Virtuoso	Pinpoints the bug down to the line number
ISFP	Adventurer	Both UI and code should be pleasing
ESTP	Entrepreneur	Fix the fire first, postmortem later
ESFP	Entertainer	Coding should be fun too

---

Custom Combos

Type "custom" and mix three dimensions to build your own AI teammate:

Thinking Style	Communication	Work Rhythm
Strategic Planner Divergent Thinker Methodical Pragmatist Action First	Minimal Enthusiastic Patient Guide Sharp Challenger	Get It Right Ship Fast

4 × 4 × 2 = 32 combinations. There's one for you.

---

Smart Recommend

Not sure which to pick? Type "recommend" and tell Claude your MBTI.

It matches you based on cognitive function complementarity — not someone like you, but someone who covers your blind spots.

You're an ENFP (Campaigner)? Creative but scattered? → The Silent Tech Lead channels your wild ideas into solid code.

You're an ISTJ (Logistician)? Reliable but too conservative? → Your Genius Teammate challenges you to break out of your comfort zone.

Don't know your MBTI? Just describe your task, and Claude recommends by task type.

Save & Manage

You: save this personality     → Writes to CLAUDE.md, persists across sessions
You: remove personality        → Removes personality settings
You: current personality       → Shows what's active

Supports project-level or global saving. Default is session-only — save when you're ready.

Auto-detects your environment and writes to the right file:

• Claude Code → ./CLAUDE.md (project) or ~/.claude/CLAUDE.md (global)
• OpenClaw → ./SOUL.md (project) or ~/.openclaw/soul.md (global)
• Hermes Agent → ./AGENTS.md (project, falls back to ./CLAUDE.md) or ~/.hermes/SOUL.md (global)

Why This Exists

MBTI isn't just a personality quiz — it describes how people approach problem-solving.

Injecting these preferences into AI isn't about accuracy, it's about creating chemistry in human-AI collaboration.

An INTJ-style Claude forces you to think architecture before coding. An ESTP-style Claude drags you into shipping before overthinking. It's not right or wrong — it's complementary.

Find the teammate you need most.
