What it does
Book Market Research is an agent skill from robertguss/claude-code-toolkit. Assess commercial viability of book concepts for Amazon KDP self-publishing. Use when the user has a Book Concept Document and wants to understand market demand, competition, pricing, and positioning before committing to write. Produces a Market Research Report with viability scorecard and Go/No-Go recommendation. Works standalone (commercial analysis only) or after idea-validator (integrated assessment). Nonfiction only.
Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files and assets (for example `assets/templates/market-research-report.md`, `references/amazon-field-guide.md` and `references/research-methods.md`).
It sits in Marketing & SEO, covering Market research, Report writing and Feature launches and release readiness. 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
- The user has a Book Concept Document and wants to understand market demand
- Positioning before committing to write
Example prompts
- “/book-market-research”

- Ask for Book Concept Document (and Validation Report if available)

- Recommend session mode with reasoning
- User confirms mode

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 Market Research loads about 2.4k tokens when it runs, and up to ~4.1k if it reads all its reference files. Until then it costs about 112 tokens; SKILL.md has 1,022 words of instructions outside code blocks.
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 1,022 words (~2,446 tokens).
“Determine if a book is worth writing from a business perspective, specifically for Amazon KDP self-publishing.”
