Trigger with: > "Write me a book about [idea]" or "Generate a bestseller about [idea]" The agent will: 1. Create output directory at `~/Desktop/books/[slug]/` 2. Run all 5 stages sequentially (chapters in parallel batches) 3. Deliver `kdp_package.md` as the final deliverable 4.

ROI is infinite. --- ## Agent Instructions (for OpenClaw) When the user asks to write a book or generate a manuscript: ### Step 1 — Collect Info Ask for (or infer from context): - The idea (required) - Genre (infer if obvious, otherwise ask) - Fiction or non-fiction ### Step 2 — Run Pipeline Create output dir: `~/Desktop/books/[slug]/` Spawn agents in sequence using `sessions_spawn` with `runtime="subagent"`: **Agent 1 — Planner:** Task: Full planning prompt (see scripts/generate.js `buildPlannerPrompt`) Save output to: `plan.md` **Agent 2 — Character Designer:** Task: Character/authority prompt with plan as context Save output to: `characters.md` **Agents 3-N — Chapter Writers (parallel, max 4 at once):** Task: Chapter writing prompt with plan + characters + prev chapter ending Save output to: `chapter_NN.md` **Agent N+1 — Editor:** Task: Editorial pass prompt with plan + sample chapters Save output to: `editorial_memo.md` **Agent N+2 — KDP Packager:** Task: KDP package prompt with plan + editorial Save output to: `kdp_package.md` ### Step 3 — Assemble Concatenate all `chapter_NN.md` files into `MANUSCRIPT.md` ### Step 4 — Deliver Send user: - Word count - Path to MANUSCRIPT.md - Key items from kdp_package.md (chosen title, pricing, first keyword string) - Next steps for publishing --- ## 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.
