Agent-Orchestrated Mode
If you're running inside an OpenClaw agent, the agent follows this pipeline directly using sessions_spawn. Trigger with:
"Write me a book about [idea]" or "Generate a bestseller about [idea]"
The agent will:
Create output directory at ~/Desktop/books/[slug]/
Run all 5 stages sequentially (chapters in parallel batches)
Cozy mysteries with recurring characters (series = repeat buyers)
Self-help for specific professions (accountants, nurses, teachers)
Business books for specific industries
Local history/interest books (low competition)

Troubleshooting
Chapters are too short?
The writer agents are prompted for 2,000-2,500 words. If output is shorter, re-run that specific chapter with: "This chapter is too short. Expand to at least 2,000 words, adding more scene depth, dialogue, and sensory detail."
Voice is inconsistent?
The editor stage catches this. After the editorial memo, re-run any flagged chapters with the specific feedback.
KDP keywords not relevant?
Edit kdp_package.md keywords manually using Google Keyword Planner or Publisher Rocket to verify search volume before uploading.
Want a series?
After Book 1 is done, pass plan.md + characters.md into a new run with --idea "Book 2: [continuation]". Characters and world are already built.
