Where this fits

You're building a writing assistant agent for a novelist who drafts in the IDE. The editor sends back "Chapter 12 needs a scene illustration," but the chapter file is buried in a reorganizing workspace, and the output folder is a mess. Your agent can generate images, but it has no repeatable workflow for which chapter to target, what to depict, or where to save results. This skill fills that gap: it resolves the chapter path, reads the prose, composes a spoiler-free visual prompt, and drops the image into assets/illustrations/ without the user leaving their editor.

Why agents benefit

• Resolves the target chapter automatically — explicit path, IDE focus, or most recent chapter from the workspace — removing the "which file?" question.
• Reads the actual chapter before prompting, so the image is grounded in the prose rather than in guesswork.
• Enforces spoiler-free rules, blocking future reversals and hidden identities from leaking into visuals.
• Produces prompts with explicit negative constraints (no text, watermarks, logos), making the output publish-ready.
• Saves to a fixed asset path, so downstream pipelines (site build, ebook export) can find the image reliably.

Practical scenarios

Deep in Chapter 7 with an editor request

The writer is mid-draft in Chapter 7 and asks for a visual. The agent detects the IDE focus, reads the chapter, and generates a scene illustration of the current tense moment — without revealing the twist later in the chapter.

Editor sends /chapter-illustration for a specific chapter

The editor passes an explicit target path. The skill uses that path, even if the IDE is open elsewhere, reads that chapter, and produces the image. The agent never asks for clarification about which file.

Workspace reorganized after a plot rewrite

Chapters have been renumbered and moved. The agent scans the chapters/ directory and the workspace summary, identifies the most recent chapter, and produces the illustration without user hand-holding.

Add it to your agent workflow

Install the skill:

npx skills add alfredxw/denova --skill chapter-illustration

Trigger it with a natural request like "Illustrate the current chapter." The agent runs the workflow, calls generate_image with purpose: "chapter_illustration" and the resolved target_path, and saves the output under assets/illustrations/.

Compare before adopting

Before adopting, weigh a few dimensions:

• Quality signals: check the skill's GitHub stars (646), README depth, and whether the prompt-writing approach matches your image-gen model's strengths.
• Maintenance freshness: check the repo's last commit date and open issues to see if the author is still shipping fixes.
• Alternatives: hand-rolled prompts, other image skills in the OpenAgentSkill catalog, or a fully custom pipeline.
• Workflow fit: confirm your agent already exposes a generate_image tool — the skill assumes that interface. Compare it with similar listings before committing.

Why it is worth tracking

This skill tackles a real gap — turning prose into visuals without breaking the author's flow — with a recipe that is easy to audit and extend. With 646 stars on the denova repo, it has visible community momentum, meaning you can expect broader testing, edge-case reports, and probable refinements. Track its issue resolution cadence and update cadence; evaluate it when your agent's illustration needs stabilize, or when your image-generation layer becomes consistent enough that a repeatable prompt workflow pays off.
