What it does

Book Toc Lab is an agent skill from hashgraph-online/awesome-codex-plugins. Design and pressure-test useful nonfiction book promises, scopes, recommendation loops, and takeaway-first tables of contents before drafting. Use when planning, outlining, scoping, restructuring, validating, or testing a practical book, guide, manual, course-like book, or other reader-outcome-focused long-form nonfiction.

Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including reference files and assets (for example `references/core/checklist.md`, `references/core/examples.md` and `references/core/knowledge.md`). Compatibility notes: Codex, Claude Code, and other Agent Skills-compatible clients.

The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is MIT.

When your agent uses it

  • Testing a practical book
  • Course-like book
  • Other reader-outcome-focused long-form nonfiction

Example prompts

  • “/book-toc-lab”

Requirements

  • Compatibility (from SKILL.md): Codex, Claude Code, and other Agent Skills-compatible clients.

Workflow steps

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

  1. Lock the reader promise before outlining.
  2. Define in-scope, out-of-scope, prerequisites, and depth lines.
  3. Write the recommendation story: trigger, recommender, recommended reader, and
  4. Draft chapters as reader takeaways, not author topic buckets.
  5. Order chapters by reader progress: orientation, foundation, action, judgment,
  6. Pressure-test every chapter against the promise, reader outcome, missing
  7. Validate the TOC before drafting when practical.

What it can do on your machine

Read from SKILL.md and the folder at commit 9e7b281. 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.

  • Compatibility

    Codex, Claude Code, and other Agent Skills-compatible clients.

    From compatibility in the SKILL.md frontmatter.

Context cost

Book Toc Lab loads about 821 tokens when it runs, and up to ~3.7k if it reads all its reference files. Until then it costs about 84 tokens; SKILL.md has 374 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~84
When it runs · the whole SKILL.md, loaded when a task matches
~821
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.7k

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.

Book TOC Lab

Treat a useful nonfiction book as a problem-solving product for a specific reader. The table of contents is the product design, not a decorative outline. Build and test the promise, scope, recommendation loop, and TOC before drafting so the manuscript has a clear job and useful progression.

Use this skill to produce or improve a book plan that answers:

  • Who is this book for?
  • What painful or valuable problem does it help them solve?
  • What should be different for the reader after each chapter?
  • What does the book deliberately leave out?
  • Why would a satisfied reader recommend it to a specific person in a specific situation?

Resource Routing

Quick planning and review checklistreferences/core/checklist.md
Step-by-step TOC design before draftingworkflows/design-toc.md
Step-by-step TOC validation with readersworkflows/validate-toc.md

Fast Workflow

  1. Lock the reader promise before outlining.
  2. Define in-scope, out-of-scope, prerequisites, and depth lines.
  3. Write the recommendation story: trigger, recommender, recommended reader, and why this book is the obvious fit.
  4. Draft chapters as reader takeaways, not author topic buckets.
  5. Order chapters by reader progress: orientation, foundation, action, judgment, and integration.
  6. Pressure-test every chapter against the promise, reader outcome, missing steps, boredom risk, confusion risk, skepticism, and recommendability.
  7. Validate the TOC before drafting when practical.

Output Format

When asked to create or improve a TOC, return:

  1. Book brief: reader, problem, promise, scope, out-of-scope.
  2. Recommendation story: trigger, recommender, recommended reader, why this book.
  3. Recommended TOC with chapter-level reader problems and takeaways.
  4. Reader journey notes explaining the order.
  5. Risk list: missing prerequisites, vague chapters, likely confusion, likely boredom.
  6. Validation plan: 3-7 concrete ways to test the TOC before drafting.

Quality Bar

A good TOC should feel useful even before the book exists. A reader should be able to scan it and understand what the book helps them accomplish, whether it is for them, and why the chapter sequence makes sense.

Do not optimize for literary cleverness before usefulness. Clever titles are acceptable only after the reader promise and chapter takeaways are obvious.
