description

WHAT: a dispatchable agent prompt that renders the actual PNG images for a blog's socials pack — hero, social-share, and thumbnail — as rich Excalidraw diagrams rendered via the render.py Playwright pipeline, visually verified. WHEN: when a socials pack exists (pack.md with IMAGE PROMPTS) but its images are not rendered (the unicorn_socials_images automation fires this), or the user says 'render the socials images' / 'make the images for this pack' (any of).

socials-images-from-pack — the pack's IMAGE PROMPTS → real PNGs

Dispatched by cave_unicorn.images.fire_socials_images via claude -p (the coglog publisher pattern) with Read/Write/Bash. Renders diagram-style images with the excalidraw render pipeline and VERIFIES each PNG by reading it.

RELIABILITY

• score: 0.90 runs: 1 verified-good: 1 last-verified: 2026-07-10
• check-level: FULL_E2E required on first runs (open the PNGs yourself)
• log (newest first):
  • 2026-07-10 PASS — first E2E on the doc-mirror pack: all three PNGs rendered and VERIFIED BY HUMAN-SIDE VISUAL READ (not the agent's claim): hero = rich before/after diagram with the thread weaving through the compaction seam; social-share = "THE DOCS WERE LYING." split with overlay space; thumbnail = high-contrast title + site URL. Dispatch gotcha fixed in module: claude -p needs ANTHROPIC_* env stripped or a sourced provider key shadows the login.

PROMPT

You are the socials image renderer. One blog's socials pack needs its images.

INPUTS:

• Socials pack: {pack_path} (its IMAGE PROMPTS section describes the three images)
• Blog markdown (source of truth for content): {blog_md_path}
• Output dir (create it): {out_dir}
• Render script: python3 {render_script} input.excalidraw output.png

Read the pack and the blog first. Then produce THREE PNGs in {out_dir}: hero.png, social-share.png, thumbnail.png — each interpreting its IMAGE PROMPTS entry as a rich EXCALIDRAW DIAGRAM (this pipeline renders diagrams, not photos: translate photographic language into diagram language — zones, colored shapes, arrows, labels).

RULES (from the proven excalidraw pipeline):

• ALL text labels are STANDALONE text elements (never only a shape label).
• Rich design: colored backgrounds, zones/groups, clear hierarchy, spacing — not minimal box-and-arrow.
• thumbnail.png: high contrast, few elements, large bold title text readable small.
• For each image: write {out_dir}/NAME.excalidraw, run the render script, then READ the PNG to verify it rendered (text present, layout sane). If broken, fix the JSON and re-render — do not leave a broken PNG.

When all three PNGs exist and are verified, print DONE and the three paths.
