Memory: CLAUDE.md

Claude Code uses CLAUDE.md files as persistent memory:

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

Update

When a new plugin version is published (e.g. 1.1.0 → 1.2.0), apply it to the current Claude Code session without a restart:

# 1. Pull latest marketplace metadata and cache the new plugin source
/plugin marketplace update jsonobject-marketplace

# 2. Hot-reload the active session so new commands/skills/agents become available
/reload-plugins

With autoUpdate: true on the marketplace (default), Claude Code also refreshes it automatically on launch — the two commands above just apply the update immediately instead of waiting for the next start.

Commands

Before you research, know WHAT to research.

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

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

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

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

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

Build prompts that resist rationalization.

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

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

Meeting notes that tell a story, not list fragments.

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

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

Rewriting in Korean, not converting English structures.

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

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

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

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

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

Fact-based blog posts that cite every claim.

A 16-year veteran blogger framework that produces source-cited IT tech articles with mandatory bullet point formatting and inline hyperlinks.

Anti-pattern: Unsourced opinion essays. This produces journalism-grade tech writing where every claim is traceable.

No answer without local grounding — every claim cites `file:line`.

Executes a 5-stage pipeline (Discovery → Map → Pinpoint → Verify → Augment) over your local .md archive to produce cite-grade answers without burning context on cold file reads.

Philosophy: The curated .md corpus is ground truth. Web is a supplement for gaps only.

90hex's discovery, operationalized — exit the beauty-stock prior with one camera body, one film stock, and an anti-AI 4-stack.

Transforms any natural-language seed (any language, any length) into an sd-dynamic-prompts mustache template (300–450 words of template surface, expanding to a 200–400 word resolved prompt per roll) for Z-Image-Turbo, plus the exact Forge Neo / ComfyUI settings.

Philosophy: ZIT's training prior is beauty stock photography. The only exit is naming a real camera body, a real film stock, and stacking anti-AI anchors. Violating the letter of the rule violates the spirit of ZIT photorealism.

MCP Server Dependencies

Setup for /deep-thinking:ground

The 5-stage pipeline leans on modern shell CLIs for Stages 1–4 and reuses the globally-installed MCP servers for optional Stage 5 web augmentation.

CLI tools — one-shot Homebrew install:

brew install fd ripgrep bat sd fzf scc tokei yq glow lychee && \
brew install harehare/tap/mq

MCP servers — Stage 5 (optional, for web gap-filling only):

No ground-specific MCP server. The optional three (Brave Search, Reddit, Fetch) are already covered in the MCP Servers Installation section above — install only if your local archive leaves gaps that need web augmentation.
