A review tool that checks a book manuscript against Amazon KDP, Amazon's self-publishing service, covering formatting, cover specifications, metadata, and genre-specific requirements. It produces a report divided into critical issues, warnings, and possible automation suggestions.

Use it to audit manuscripts in formats such as LaTeX, Word, EPUB, Markdown, PDF, or Kindle Create projects.

It shows what may need fixing before a book is submitted to KDP, including issues specific to technical books, fiction, or nonfiction.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00059	$0.02629
Opus 5	$0.00030	$0.01314
Sonnet 5	$0.00012	$0.00526
Haiku 4.5	$0.00006	$0.00263

Security

Grade A, and why

kdp-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

KDP Manuscript Audit

Audit a book manuscript against Amazon KDP (Kindle Direct Publishing) requirements and produce a structured gap report. This skill evaluates interior formatting, cover specs, metadata completeness, and genre-specific requirements (technical vs. fiction).

Workflow

1. Detect Manuscript Type

Identify manuscript files and format. Look for these file types in the current directory or specified path:

Primary manuscript formats (Glob tool):

.tex files (LaTeX manuscripts, common for technical books)
.docx files (Microsoft Word, common for fiction/nonfiction)
.epub files (eBook source)
.md files (Markdown manuscripts)
.pdf files (final output)
.kpf files (Kindle Create project)

Manuscript type classification:

Technical: LaTeX source, math equations, code listings, index/bibliography
Fiction: Structured chapters, scene breaks, dialog formatting
General nonfiction: Standard chapters, images, minimal equations

If no manuscript is found, ask the user which file to audit.

1b. Load User Config

Read .claude/kdp.local.md if it exists (Read tool). Extract the kdp configuration section and author metadata from YAML frontmatter. The config may include:

kdp:
  trim_size: "6x9"
  paper_type: "white"
  binding: "paperback"
  genre: "technical"
  target_page_count: 300
author:
  name: "Author Name"
  bio: "Brief author bio"

If the file is missing, inform the user and offer to create one from the template at ${CLAUDE_PLUGIN_ROOT}/docs/user-config-template.md.

2. Check Interior Formatting

Verify the manuscript meets KDP interior requirements. Full specs are in ${CLAUDE_PLUGIN_ROOT}/docs/kdp-reference.md (Interior Formatting section); read it and check the manuscript against:

Trim size: look for margin or geometry declarations (Grep tool); verify it matches a KDP-supported size (common for nonfiction 6x9, fiction 5.5x8.5 or 5x8, textbooks 7x10 or 8.5x11)
Margins: inside margin grows with page count (formula 0.375" + page_count / 1000 * 0.125"), outside at least 0.25", gutter at least 0.5" for 150+ pages
Fonts: must be embedded; standard fonts preferred (Times New Roman, Garamond, Arial, Courier); minimum 7pt
Page numbers: start after front matter, consistent placement
Table of Contents: present and functional, hyperlinked in eBook, typically 2 to 3 levels deep

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

kdp-audit is a skill published in the GitHub repository queelius/claude-anvil (2 stars, last pushed 2mo ago), licensed MIT. It adds 59 tokens to every session and 2,629 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
