Name: ljg-learn
Author: lijigang/ljg-skills

Deep concept anatomist that deconstructs any concept through 8 exploration dimensions (history, dialectics, phenomenology, linguistics, formalization, existentialism, aesthetics, meta-philosophy) and compresses insights into an epiphany. Use when user asks to explain, dissect, or deeply understand a concept, term, or idea. Triggers on '解剖概念', '概念解剖', 'explain concept', 'learn concept', '/ljg-learn'. Produces org-mode output.

1How It Works & Mechanism

Overall Stance: Treat any concept as an anatomical subject, dissect it across eight dimensions, and finally compress it into an epiphany.

skills/ljg-learn/SKILL.md

你是概念解剖师。拿到一个概念，从八个方向切开它，最后把所有切面压成一句顿悟。

What this does: Establishes the skill's role and guiding principle—eight-dimensional slicing + final compression, rather than an encyclopedic explanation.

Step 1 'Anchoring': Clarify common definitions and misconceptions first, then unpack core morphemes/etymological roots.

skills/ljg-learn/SKILL.md

1. 这个概念最通行的定义是什么？常见误解在哪？

What this does: Fixes the semantic boundaries of the subject before making the eight cuts, preventing deviations.

Step 2 'Eight Cuts': Make one cut across each of the eight dimensions, keeping only the skeletal essence in 2-3 sentences per cut.

skills/ljg-learn/SKILL.md

八个方向各切一刀。每刀 2-3 句，只留筋骨，不带水分。

What this does: Uses fixed eight dimensions as an anatomical scaffold and enforces length limits to drive density.

The eight dimensions consist of History, Dialectics, Phenomenology, Linguistics, Formalization, Existentialism, Aesthetics, and Meta-reflection, each with defined action items.

skills/ljg-learn/SKILL.md

**历史**：最早从哪冒出来 → 怎么变的 → 哪一步拐成了今天的意思

What this does: Translates the abstract 'eight cuts' into eight actionable, concrete prompts.

Step 3 'Introspection': Embody the concept itself to view the world in the first person, identifying cuts that point to the same deep structure.

skills/ljg-learn/SKILL.md

变成这个概念本身，用第一人称看世界。3-5 句。

What this does: Restores the experience from inside the concept and converges the eight cuts onto a shared deep structure.

Step 4 'Compression': Generate a three-piece set consisting of a formula, a one-sentence epiphany, and a pure ASCII structural diagram.

skills/ljg-learn/SKILL.md

**结构图**：纯 ASCII 画出概念的骨架

What this does: Compresses the anatomical findings into a minimal, repeatable, and drawable form.

Formatting Iron Rule (Zero Exceptions): Output must be pure org-mode; Markdown syntax is explicitly prohibited.

skills/ljg-learn/SKILL.md

输出必须是纯 org-mode 语法，禁止任何 markdown 语法

What this does: Enforces output syntax with a zero-exception rule to ensure seamless integration into org-mode note systems.

Write Workflow: Retrieve timestamp, write to ~/Documents/notes/, and report the full path.

skills/ljg-learn/SKILL.md

运行 `date +%Y%m%dT%H%M%S` 获取时间戳。

What this does: Saves the final output as a timestamped org file and returns the path via local host actions.

2Core Capabilities

01Eight-dimensional concept dissection: one cut each across history / dialectics / phenomenology / linguistics / formalization / existentialism / aesthetics / meta-reflection

02Anchoring: clarify common definitions, dispel misconceptions, and unpack core morphemes

03Introspection: reconstruct the concept's experience in first-person and extract shared deep structures

04Compression trio: formula + one-sentence insight + pure ASCII structural diagram

05Pure org-mode output, strictly adhering to zero-exception formatting rules (Markdown syntax prohibited)

06Automatic naming and writing to local ~/Documents/notes/ knowledge base

07Chinese trigger phrases and slash command /ljg-learn entry point

Evidence & Triggers (File Paths & Excerpts)

本地工作目录: File I/O and artifact output: ~/Documents/notes/{timestamp}--概念解剖-{概念名}__concept.org (written via host Write tool, skill

Audit Notes: Pure prompt-based workflow: Directory contains only one SKILL.md, with no scripts, network requests, or credential reads. The body instructs the host to run date to get a timestamp and write a local org file, which is a local host Bash/Write action; based on assessment criteria, the rating tier remains unchanged, recorded only under file_writes.

5Second-Pass Verification

[ok] 八维清单完整 — §八刀列出历史/辩证/现象/语言/形式/存在/美感/元反思并各附动作，与引用一致。
[ok] 五步流程结构 — §1-§5（定锚/八刀/内观/压缩/写入）齐备，压缩内含公式、一句话、结构图三项。
[ok] 格式铁律五条 — §写入列出纯 org-mode、粗体 *bold*、禁用 ---、列表语法、~code~ 五条，与 traits 一致。
[ok] 写入路径与命名 — 写 ~/Documents/notes/{timestamp}--概念解剖-{概念名}__concept.org，时间戳由 date 取得，逐字命中。
[discrepancy] 扫描报无外部程序/写盘 vs 正文要求 date 与写文件 — 风险扫描六类均零命中，但 §写入明确要求运行 date 并写 org 文件；判为宿主本地动作（非 skill 自带脚本），已记入 file_writes 并在 reason 说明。
[ok] 外部依赖与凭证 — 全文无 URL、无 API、无包依赖，external_deps 据实留空。

6Verdict & Scenarios

Structured eight-dimensional dissection scaffolding that prevents concept explanations from devolving into generic platitudes.

Strict formatting discipline (pure org-mode, ASCII diagrams) allowing direct integration into org note-taking workflows.

Compression into 'formula + one sentence + structural diagram' forces out repeatable core insights.

Best for: Ideal for writers and learners seeking to deeply dissect a concept quickly and structurally, especially users who preserve thoughts in org-mode notes; also suitable as a templated service for thoroughly mastering a term.

Not for: Not suitable for: conceptual research requiring authoritative citations and references; users seeking encyclopedic comprehensive definitions; non-org-mode workflows without local file writing capabilities; and scenarios with zero tolerance for non-factual interpretations that reject philosophical analysis.
