What it does
Book Research Assistant is an agent skill from robertguss/claude-code-toolkit. Plan, orchestrate, and validate deep research for nonfiction books. Use when an author has completed book architecture and needs to fill research gaps before outlining chapters. Triggers include requests to plan research, generate research prompts, validate research quality, or prepare for drafting. This skill does everything around deep research—planning, prompting, validating, synthesizing—but the actual research execution happens externally via Claude and Gemini deep research. Requires upstream documents from…
Its SKILL.md is about 3.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 21 other files, including reference files and assets (for example `assets/templates/book-level-tracker-template.md`, `assets/templates/chapter-research-summary-template.md` and `assets/templates/chapter-research-tracker-template.md`).
It sits in Research & Science, covering Deep 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 completed book architecture and needs to fill research gaps before outlining chapters
- Include requests to plan research
- Generate research prompts
- Validate research quality
Example prompts
- “/book-research-assistant”
Workflow steps
2 steps, taken from the step headings in SKILL.md.
- Research Planning
- Research Validation
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 Research Assistant loads about 3.7k tokens when it runs, and up to ~27k if it reads all its reference files. Until then it costs about 169 tokens; SKILL.md has 1,486 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 1,486 words (~3,680 tokens).
“Plan, orchestrate, and validate deep research for nonfiction books. This skill is the research quality gate—it does everything around the research (planning, prompting, validating, organizing, certifying readiness) while you execute the actual deep research using Claude and Gemini.”
