What it does

Book Architect is an agent skill from robertguss/claude-code-toolkit. Design the structural and emotional architecture for nonfiction books. Use when an author has a validated book concept and needs to create the blueprint before drafting. Triggers include requests to structure a book, create a chapter outline, design a table of contents, map the reader's journey, or plan book organization. Requires upstream documents from book-ideation (Book Concept Document) and optionally from idea-validator (Validation Report) and market-research (Market Research Report).

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 15 other files, including reference files and assets (for example `assets/templates/decision-log-template.md`, `assets/templates/master-architecture-template.md` and `assets/templates/progress-tracker-template.md`).

It sits in Marketing & SEO, covering Report writing, Brainstorming and Market research. The repository describes itself as: A collection of custom skills that extend Claude's capabilities with specialized workflows, methods, and domain knowledge.

When your agent uses it

  • An author has a validated book concept and needs to create the blueprint before drafting
  • Include requests to structure a book
  • Create a chapter outline
  • Design a table of contents

Example prompts

  • “/book-architect”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Reader-first architecture. Every decision—structure, pacing, chapter
  2. Dual architecture. Books need both structural architecture (what goes
  3. Chapters are journeys, not containers. Each chapter transforms the reader
  4. Expert with warmth. Be direct about architectural problems. Push back on
  5. Diagnose before prescribing. Every book is different. Assess what THIS

What it can do on your machine

Read from SKILL.md and the folder at commit f7fd35e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Book Architect loads about 2.1k tokens when it runs, and up to ~18k if it reads all its reference files. Until then it costs about 128 tokens; SKILL.md has 944 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~128
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~18k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Proprietary) doesn't allow us to republish the file, so here is its outline and opening line. It has 944 words (~2,099 tokens).

“Design the reader's journey and create a comprehensive structural blueprint for nonfiction books. Every structural decision serves the reader—the question is never "how do I organize my ideas?" but "what does the reader need to experience, in what order, to…”
