BC book-author
Complete indie author skill: book writing, editing, KDP/IngramSpark publishing, Amazon keyword research, book marketing, and launch execution. Covers the full pipeline from concept to bestseller ranking. Activate when: any agent is writing a book chapter, drafting a manuscript, creating a book outline or blueprint, reviewing chapter quality, running a humanization pass, scoring a chapter draft, assembling a full manuscript, writing a book description, researching Amazon keywords, optimizing KDP metadata, planning a book launch, writing marketing copy, setting up ARC campaigns, analyzing BSR or sales rank, formatting for KDP or IngramSpark, or doing any work in the book creation and publishing pipeline. Also activate when agents mention "humanization rules", "quality checklist", "chapter brief", "book blueprint", "KDP", "IngramSpark", "BISAC", "Amazon keywords", "book launch", "ARC readers", "BSR", "manuscript", "book description", "A+ Content", "KDP Select", "wide distribution", "book marketing", or any book-related writing or publishing task. Covers all genres: health/medical non-fiction, children's books, faith/ministry, AI/technology, literary fiction, commercial fiction, self-help, and business books.
As a process C 55/100 · Has gaps — weak spots: when it triggers, inputs and preconditions, consistency
How to improve
- Shorten the description to 1024 characters.
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

frontmatter-keyunknown frontmatter key "requires"
Process rating: all ten parameters 55/100
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Progress reporting. Says nothing while it works
- 20When it triggers. No condition that starts the skill
- 30Running it twice. 16 mutating operations with no state check
- 40Consistency. Frontmatter name (book-author) differs from the folder (kdp-author-engine)
- 60Tools and files. Uses tools (node) that frontmatter does not declare
- 60Result and completion. Output format stated, no completion criterion
- 85Steps. 108 steps, 1 vague phrases
- 100Failures and branches. 3 branches, has a failure section
- 100Execution cost. Instruction body is 3096 tokens
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
- low 10 top-level sections: this looks like several domains in one skill
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
