Memory: CLAUDE.md

Claude Code uses CLAUDE.md files as persistent memory:

Path	Scope
~/.claude/CLAUDE.md	Global (all projects)
./CLAUDE.md	Project-specific

The CLAUDE.md in this repository root serves as the global memory template, defining behavioral rules, MCP server usage patterns, and response preferences.

Deep Thinking Plugin

This repository is a Claude Code Plugin Marketplace containing the deep-thinking plugin.

Installation

# Add marketplace (one-time setup)
/plugin marketplace add JSON-OBJECT/claude-code

# Install plugin
/plugin install deep-thinking@jsonobject-marketplace

# Restart Claude Code to load the plugin

Commands

/deep-thinking:pulse {topic} — Trend Radar

Before you research, know WHAT to research.

Scans 5-8 subreddits × 75+ posts to identify what's genuinely hot RIGHT NOW.

Feature	What It Does
Heat Score Formula	Objective ranking: (Upvotes × 0.4) + (Comments × 0.3) + (Cross-sub × 0.2) + (Recency × 0.1)
News Cross-Validation	Compares Reddit trends against mainstream news — prevents echo chamber reports
Emerging Signals Watch	Tracks low-heat topics with rising momentum — tomorrow's headlines today
Actionable Output	Every issue includes a ready-to-run /deep-research query

Use before: /deep-research — ensures you research the RIGHT topic, not just any topic.

---

/deep-thinking:deep-research {topic} — Forensic Tech Audit

One-shot research that answers questions before you ask them.

Conducts 15-20+ searches with mandatory Phase Zero "Unknown Unknowns" discovery.

Feature	What It Does
Phase Zero Protocol	Questions the question itself — catches terminology confusion, outdated assumptions, missed prerequisites
One-Shot Completeness	Anticipates 5 follow-up questions ("What is it?" → "How much?" → "Gotchas?" → "Show code" → "Verdict?") and answers ALL in one report
Ki-Sho-Ten-Ketsu Structure	Four-act narrative (Setup → Development → Turn → Conclusion) — reads like investigative journalism, not bullet lists
Community + Official Balance	Reddit/HN sentiment weighted proportionally against official sources — 70% positive / 30% concern = both reported

Output: Publication-ready deep dive that feels like Ars Technica meets Gemini Deep Research.

---

/deep-thinking:forge-prompt {instruction} — Instruction Smithy

Build prompts that resist rationalization.

Creates bulletproof instructions following the Superpowers philosophy with 9 mandatory components.

Component	Purpose
Iron Law	ONE non-negotiable rule that guarantees failure if broken
Red Flags Section	Mental patterns that signal you're about to fail — "If you catch yourself thinking..."
Rationalization Table	Preempts every excuse with direct rebuttal — Excuse | Reality format
Phase Gates	Clear checkpoints that MUST be passed before proceeding
Strong Language Protocol	MUST/NEVER/ALWAYS — no soft language ("should", "consider", "try to")

Philosophy: If you think you don't need the structure, you need it most.

---

/deep-thinking:meeting-notes {transcript} — Narrative Documentation

Meeting notes that tell a story, not list fragments.

Transforms raw transcripts into narrative-driven documentation with 6-phase verification.

Feature	What It Does
Counterparty Intelligence	External meetings: 3+ searches per counterparty for context (size, tech stack, recent news)
STT Error Correction	Catches phonetic mishearings ("jenkinsun" → "Jenkins") with 2+ source verification
Immediate Inline Definitions	Technical terms explained right where they appear (> 📘 format), not buried in glossary
Storytelling Tone + Metaphors	Mandatory 1-2 metaphors per document — "From gatekeeper to guardrail" style
Zero Detail Loss	Every business-relevant point preserved — 400-5000+ words scaled to source density

Anti-pattern: Bullet lists. This produces flowing narrative with cause-and-effect reasoning.

---

/deep-thinking:translate-kr {article} — Korean Transcreation

Rewriting in Korean, not converting English structures.

Transcreates English IT articles into native Korean with terminology verification and 10 anti-artifact rules.

Feature	What It Does
Tier 1/2 Verification	Established terms: 1 official source / New terms: 2+ sources including community (velog, tistory)
10 Anti-Translation-Artifact Rules	Pronoun elimination, Passive→Active, Sino-Korean ban, Emotional modifier ban, etc.
Community Standard Priority	If Korean dev community uses English 70%+ of the time, keep English (Token, Prompt, Fine-tuning)
Code Block Protection	NEVER modifies content inside code blocks or inline code

Key insight: "Fine-tuning" → "파인튜닝" (community usage), NOT "미세 조정" (textbook translation).

---

/deep-thinking:blog-cover {title and concept} — Creative Director for Gemini

Anti-AI-looking blog covers that make readers curious.

Generates image prompts for Gemini Nano Banana Pro with 6-phase visual storytelling.

Feature	What It Does
Visual Metaphor First	Every cover starts with an unexpected analogy — "Kubernetes = postal worker sorting containers"
Chain-of-Thought Composition	Explicit 9-grid spatial positioning — asymmetry always, center composition = AI tell
Anti-AI Armor	Mandatory "Avoid" section with 8+ items (symmetry, HDR, plastic textures, generic tech imagery)
Imperfection Keywords	2-3 required: "visible brushstrokes", "analog film grain", "slightly uneven lines"
Title Typography Mandatory	Every prompt includes title overlay specifications — covers without title = incomplete

Artist references: Christoph Niemann, Saul Steinberg, The New Yorker editorial style.
