Why This Exists

There's a recent viral idea: distilling colleagues into AI skills. Even after someone leaves, their experience, tone, and work style can be partially replicated by AI. nuwa-skill does exactly this — creating "human skills" like an Elon Musk skill or a Warren Buffett skill. The companion darwin-skill handles automatic skill evolution.

Distilling people is valuable — nuwa-skill has already proven this. Distilling what people have written is a complementary dimension: a book represents years of deliberate thinking — the distilled essence of careful reflection. Rather than imitating someone's expression style, extracting their systematically produced methodologies into tools that help people solve real problems is equally valuable.

There's also a real pain point: you might read many books but struggle to apply them. Knowledge stays at the "I've read it" level and never gets activated in real decisions. Once a book is distilled into skills, an AI agent can invoke that knowledge in real scenarios — instead of letting it gather dust in your notes.

So cangjie-skill has one clear goal: distill every book worth distilling, turning each high-value book into a set of independently callable, composable, and pressure-testable AI skill packs.

What Problems It Solves

Reading many books but never applying them — knowledge stays at "I've read it" and never activates in real decisions
Book summaries and reading notes are compression, not structured reuse — you still don't know "when to use what"
Only a small fraction of a book deserves to become a tool — strict filtering is needed, not wholesale inclusion
Existing reading methodologies are designed for human readers, not agent executors — distillation must be execution-oriented, not reading-oriented

How It Works

cangjie-skill uses the RIA-TV++ pipeline to transform a book from raw text into a set of structured skills. The process has seven stages:

Whole-Book Comprehension (Adler Analysis) — Structural, interpretive, critical, and applicability analysis using Mortimer Adler's method, producing BOOK_OVERVIEW.md
Parallel Extraction — Five specialized extractors (frameworks, principles, cases, counter-examples, glossary) run simultaneously to pull candidate units from the source text
Triple Verification — Each candidate must pass three checks: at least 2 independent supporting passages (cross-domain), ability to answer a novel question (predictive power), and non-commonsense uniqueness. Pass rate is typically 25-50%
RIA++ Construction — Verified content is structured into six dimensions: R (original quote) / I (own-words reconstruction) / A1 (book cases) / A2 (future trigger scenarios) / E (executable steps) / B (boundaries & blind spots)
Zettelkasten Linking — Dependency, contrast, and composition relationships between skills are identified, producing INDEX.md with a reference graph
Pressure Testing — Test prompts including bait questions (and cross-skill confusion tests) are designed for each skill; failures go back for full reconstruction
Delivery — A reader-facing DIGEST.md long-form digest is generated (skip the book, read the essence), and tested skills are installed into the Claude Code / Cursor skills directory so they can actually be invoked

The name RIA-TV++ breaks down as:

RIA: From Zhao Zhou's bookmark method (Reading / Interpretation / Appropriation)
TV: Triple Verification
++: Agent-oriented extensions — E (Execution) + B (Boundary)

Effect Examples

Example 1: From a Book to a Skill Pack

User Need

"I want to turn a book's core methodologies into reusable AI skills, not just a reading summary."

How cangjie-skill reasons

Check whether the source material has reusable methodological units
Distinguish what deserves to be a standalone skill vs. background material
Output a structured skill repository, not a single summary document

Example Output

The result will not be one summary document. It will be a multi-skill repository with BOOK_OVERVIEW.md, INDEX.md, a reader-facing DIGEST.md, a GLOSSARY.md, multiple */SKILL.md files, and test-prompts.json for trigger testing.

Example 2: Structured Reuse, Not Compression

User Need

"I don't want a long explanatory article. I want a skill pack my agent can reuse."

How cangjie-skill reasons

Target is structured reuse, not narrative compression
Prioritize triggerable, composable, testable skill units
Reject material that doesn't deserve standalone skill status

Example Output

The system produces multiple skill modules with trigger conditions, boundaries, execution patterns, and related-skill links — rather than flattening the source into one generalized note.

Ecosystem

cangjie-skill is part of a larger skill ecosystem:

nuwa-skill — Distills people (thinking styles, expression DNA)
cangjie-skill (this repo) — Distills books (methodologies, frameworks, principles)
darwin-skill — Evolves any skill

They interlock: nuwa distills people, cangjie distills books, darwin keeps them evolving.
