# Lovstudio Write Professional Book > Write multi-chapter books (technical, tutorial, monograph, etc.) end-to-end. Handles outline planning, per-chapter drafting that stays coherent across long manuscripts, chapter review, and final HTML/PDF build. Trigger when user mentions "写书", "写一本书", "出书", "技术书", "book writing", "逐章写作", "O'Reilly", "mdbook", or wants to author a multi-chapter book. Use when this capability is needed. - Skill: `tomevault-io/lovstudio-write-professional-book` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/lovstudio-write-professional-book` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/lovstudio-write-professional-book/raw - Safety review: pending (external: skill-scanner PASS, skillspector CAUTION) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Web & Frontend - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/lovstudio-write-professional-book --- # write-professional-book (encrypted) This skill's real instructions are encrypted. To use it, decrypt them first: ```bash uvx lovstudio-skill-helper decrypt write-professional-book ``` **What to do:** 1. Run the command above. 2. The output is the actual SKILL.md for write-professional-book. Read it as if it were these instructions, and follow it to the letter. 3. If the command prints `error: not activated` or `error: not logged in`, tell the user: > 这是一个 Lovstudio 付费 skill，请先激活： > ``` > npx lovstudio license activate lk- > ``` > 还没有 license key？前往 https://lovstudio.ai 购买，或关注 #公众号：手工川 购买。 4. If the command prints `error: not entitled`, the helper will interactively prompt the user to (a) enter a license key, (b) open the purchase page, or (c) cancel. Just let the user pick. 5. If the command prints `error: skill 'write-professional-book' not installed`, the encrypted bundle isn't on disk yet. Tell the user: > ``` > npx lovstudio skills add write-professional-book -g -y # 只装这一个 > npx lovstudio skills add skills -g -y # 一次装全部 > ``` 6. Do NOT cache the decrypted output between invocations — always re-decrypt on each use. The decryption is cheap (one HTTP round-trip) and re-running guarantees the user's license is still valid. 7. If the decrypted SKILL.md references additional files (e.g. `references/workflow.md`, `assets/...`), DO NOT use the `Read` tool on them — those paths only exist on disk as encrypted `.enc` blobs. Instead, decrypt each one on demand by passing its relative path as a second argument: ```bash uvx lovstudio-skill-helper decrypt write-professional-book references/workflow.md ``` Requires lovstudio-skill-helper ≥ 0.9.0. Earlier versions only decrypt SKILL.md. The encrypted payload lives in one of: - `~/.claude/skills/write-professional-book/` - `~/.claude/skills/lovstudio-write-professional-book/` You don't need to touch it directly — just call `uvx lovstudio-skill-helper decrypt write-professional-book []`. --- > Source: [lovstudio/skills](https://github.com/lovstudio/skills) — distributed by [TomeVault](https://tomevault.io).
