A Response to This World: https://t.co/q9JL7v4nXv — # lijigang/ljg-skills Source: https://github.com/lijigang/ljg-skills # ljg-skills My custom skill set for Claude Code (https://docs.anthropic.com/en/docs/claude-code).
Installation
Install with a single command using the skills CLI (https://github.com/vercel-labs/skills) (powered by npx):
# Install all skills (globally, org-mode format)
npx skills add lijigang/ljg-skills -g --all
# Install all skills (Markdown format, suitable for Obsidian / VSCode / Notion, etc.)
npx skills add lijigang/ljg-skills#md -g --all
# Install a single skill
npx skills add lijigang/ljg-skills -g --skill ljg-card
# Install a single skill (Markdown format)
npx skills add lijigang/ljg-skills#md -g --skill ljg-card
# Install multiple specified skills
npx skills add lijigang/ljg-skills -g --skill ljg-card --skill ljg-learn
# List available skills in the repository
npx skills add lijigang/ljg-skills -l
Parameter Guide:
| Parameter | Description |
|---|---|
-g | Install globally to ~/.claude/skills/ (recommended). If omitted, installs to the current project’s .claude/skills/. |
--skill | Specify a specific skill to install. Can be repeated. |
--all | Install all skills in the repository. |
#md | Install the Markdown format version from the md branch (defaults to org-mode). |
-l | List available skills only without installing. |
ljg-card
The ljg-card skill relies on Playwright for screenshots. After installation, run the following extra steps:
cd ~/.claude/skills/ljg-card && npm install && npx playwright install chromium
Alternative Method: Git Clone
# Org-mode version
git clone https://github.com/lijigang/ljg-skills.git ~/.claude/plugins/ljg-skills
# Markdown version
git clone -b md https://github.com/lijigang/ljg-skills.git ~/.claude/plugins/ljg-skills
Skills
| Skill | Description |
|---|---|
| ljg-card | Content-to-Card — Converts content into PNG visual cards (long image -l, infographic -i, multi-card -m, visual note -v, comic -c, whiteboard -w, large text -b) |
| ljg-learn | Concept Dissection — Deconstructs a concept along eight dimensions (historical, dialectical, phenomenological, linguistic, formal, existential, aesthetic, meta-reflection), distilled into a single epiphany |
| ljg-paper | Paper Reading — Extracts core ideas from academic papers for non-experts, focusing on comprehension over critique |
| ljg-paper-river | Paper Genealogy — Uses a reverse-reading approach to recursively trace preceding papers (up to 5 layers) + latest developments, narrating the evolution of a problem from its origins |
| ljg-qa | Q&A Generator — Distills core viewpoints from articles/papers/books into Q&A chains. Questions hit the key points, while answers are structured in four parts (conclusion / formalization / steps / boundaries) |
| ljg-plain | Plain Language Engine — Rewrites any content so that even a bright 12-year-old can understand it |
| ljg-rank | Rank Reduction Engine — Given a domain, identifies the irreducible independent generators behind it |
| ljg-think | First Principles Arrow — Given a viewpoint or phenomenon, drills vertically down to its indivisible essence |
| ljg-word | Word Mastery — Deeply deconstructs an English word’s core semantics and moment of realization |
| ljg-writes | Writing Engine — Slices open a viewpoint like a scalpel, peeling back layers to the core. Produces 1000–1500 words |
| ljg-invest | Investment Analysis — Core focus on determining whether a project functions as an “order-creating machine” |
| ljg-read | Reading Companion — Reads any text alongside you, featuring three-tier English translation (faithfulness, expressiveness, elegance) + structural annotation + deep questioning + cross-domain extensions |
| ljg-relationship | Relationship Analysis — Five-layer structural diagnosis combined with psychoanalysis. Guides users through dialogue to help them “see” the true structure of their relationships |
| ljg-roundtable | Roundtable Discussion — Truth-seeking, structured multi-person dialectical dialogue. Generates an ASCII thinking framework diagram each round |
| ljg-travel | Travel Research — Enter a city name to generate an in-depth cultural research document (org-mode) + portable cards (PNG) |
| ljg-skill-map | Skill Map — Scans all installed skills and renders a visual overview |
| ljg-present | Presentation Forge — Defaults to Takahashi style (one keyword per page, cream background with dark text); -s flag enables slogan style (VACAT/BIG STUDIOS vibe: black-red dual-color blocks, ultra-bold, full assertion sentences filling the screen) |
| ljg-push | Push Engine — One-click syncs local ~/.claude/skills/ljg-* files to a GitHub repository (maintaining both master and md branches) |
Workflows
Workflows chain multiple skills together into a single command.
| Workflow | Skill Chain | Description |
|---|---|---|
| ljg-paper-flow | ljg-paper → ljg-card -c | Reads a paper and generates a comic-style card in one go |
| ljg-word-flow | ljg-word → ljg-card -i | Performs deep word analysis and creates an infographic card seamlessly |
Output Formats
The skills offer two output formats depending on which branch you install. Functionality remains identical:
| Branch | Format | Use Case |
|---|---|---|
master (default) | Org-mode (.org) | For Emacs / Denote users |
md | Markdown (.md) | For users in the Markdown ecosystem (Obsidian, VSCode, Notion, etc.) |
