ebook-discoverySurface ebook ideas you didn't know you had. An agent skill from robertguss/claude-code-toolkit.
Ebook Discovery is an agent skill from robertguss/claude-code-toolkit. Surface ebook ideas you didn't know you had. Use when ready to discover what ebooks might be hiding in your content, expertise, or thinking. Supports both content-rich creators (blog posts, videos, newsletters) and those with unpublished expertise. Produces a curated list of ebook candidates ready for Concept Development. Handles multi-session discovery with living documents.
Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files, including reference files and assets (for example `assets/templates/discovery-tracker-template.md`, `assets/templates/handoff-summary-template.md` and `references/candidate-assessment.md`).
It sits in Documents & Office, covering Blog and article writing and Newsletters. The repository describes itself as: A collection of custom skills that extend Claude's capabilities with specialized workflows, methods, and domain knowledge. The licence is MIT.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit f7fd35e. It shows what the files ask for, not the result of running them.
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.
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.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Ebook Discovery loads about 2k tokens when it runs, and up to ~23k if it reads all its reference files. Until then it costs about 99 tokens; SKILL.md has 936 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.
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.

This is genuine intellectual partnership, not facilitated questioning:
Unlike generic brainstorming, constantly apply ebook-specific pressure:
1. Orientation Question:
"Let me understand your starting point. Some creators come to this with published content to mine—blog posts, newsletters, videos, podcasts. Others have deep expertise that hasn't made it into published form yet. Honestly, both are rich territory for ebook discovery. Which sounds more like you?"
2. Recommend Starting Mode:
Based on their answer, recommend a starting entry mode with reasoning:
3. Intent Question:
"One more thing before we dive in: What's driving you to create ebooks? Direct income? Building authority? Serving your audience? A passion project? Understanding this helps me know which candidates are most worth your time."
4. Create Tracker:
Ask where to save the Discovery Tracker, suggest a default location, then create
using assets/templates/discovery-tracker-template.md.
5. Begin Exploration:
Dive deep into the selected mode. See references/entry-modes-guide.md for
detailed guidance on each mode.
During exploration:
At session transitions:
In the tracker:
See references/candidate-assessment.md for viability criteria and examples.
When user returns with existing tracker:
Claude introduces modes progressively with reasoning. User can request the full list anytime.
Content-Based (mine what you've published):
Audience-Based (learn from your readers/viewers): 4. Repeated Questions Analysis — YouTube comments, email replies, questions after talks
Knowledge-Based (surface what you know): 5. Expertise Extraction — Tacit knowledge that feels obvious to you but valuable to others 6. Contrarian Positions — Views that push against mainstream thinking 7. Translation Bridges — Things you explain between worlds you inhabit 8. Personal Systems — Workflows, processes, disciplines you've developed
Archive-Based (dig through your thinking): 9. Zettelkasten Mining — Clusters of connected notes revealing ebook-shaped ideas 10. Parking Lot Review — Ideas parked during brainstorms, cross-project intersections 11. Deep Archive Mining — Book marginalia, reading responses, long emails, "I wish this existed" frustrations
For detailed guidance on each mode: See references/entry-modes-guide.md
For the expertise extraction path (harder, needs dedicated support): See
references/expertise-extraction-guide.md
A candidate is ready for Concept Development when:
Use assets/templates/handoff-summary-template.md for clean handoff.
Note: "This candidate is ready for the Ebook Concept Development skill."
Use assets/templates/discovery-tracker-template.md for the living document.
Create after orientation is complete. Update at milestones, not constantly.

Ebook Discovery fits situations like: ready to discover what ebooks might be hiding in your content; tasks that involve Blog and article writing; tasks that involve Newsletters.
Run `npx skills add robertguss/claude-code-toolkit --skill ebook-discovery -a claude-code`. Or copy the skill folder (skills/ebook-factory/ebook-discovery in robertguss/claude-code-toolkit) into .claude/skills/ebook-discovery in your project. Claude Code loads it when a task matches its description.
Run `npx skills add robertguss/claude-code-toolkit --skill ebook-discovery -a codex`. Or copy the skill folder (skills/ebook-factory/ebook-discovery in robertguss/claude-code-toolkit) into .agents/skills/ebook-discovery in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add robertguss/claude-code-toolkit --skill ebook-discovery -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/ebook-discovery, .gemini/skills/ebook-discovery, .github/skills/ebook-discovery and .opencode/skills/ebook-discovery in your project.
SKILL.md names no scripts, command-line tools or credentials: Ebook Discovery is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Ebook Discovery is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2k tokens (SKILL.md is roughly 8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 21k tokens, read only when the agent opens those files.
