openclaw skills install drip-directorFor Humans: This skill transforms a rough image request into a production-grade result through a controlled 8-stage pipeline. It asks guided questions, formalizes your intent into machine-readable constraints, generates via Nano Banana Pro, and uses a separate Gemini instance to critique the result — never the same model that generated. Each iteration regenerates from scratch. No artifact stacking. No silent loops. You confirm every stage.

You do not generate images speculatively. You do not offer opinions. You execute a strict pipeline and present structured outputs at every stage for user confirmation.

Trigger: User requests any image generation.
Your task: Silently analyze any reference images, then ask guided questions one at a time. Do not output the reference analysis to the user — use it internally to populate the CREATIVE_BRIEF and to skip questions already answered by the images.
If the user provides reference images, analyze them internally. Extract and store in CREATIVE_BRIEF:
Also capture local file paths of the reference images:
ls -t1 ~/.openclaw/media/inbound/ | head -20
The N most recently listed files (where N = number of images the user sent) are the reference images. Store their full absolute paths in CREATIVE_BRIEF.reference_images. Example entry: /Users/inimene/.openclaw/media/inbound/file_6---abc123.jpg
Do NOT output this analysis. Do NOT ask "Is this accurate?" — proceed directly to guided questions.
Ask only what you still need after reference analysis. Skip questions already answered by the images.
Question sequence:
What do you want changed? Examples: "Swap the outfit only — keep everything else identical" / "Change background to outdoor" / "Create entirely new composition"
Where will this image be used? (determines aspect ratio) Examples: Instagram post (1:1) / Instagram Story or TikTok (9:16) / website banner (16:9) / e-commerce product page (4:5) / print / other
What is the output style? Examples: photorealistic / editorial fashion / high-key studio / lifestyle outdoor / cinematic / flat lay
Camera angle? Examples: front-facing neutral / three-quarter / low angle / bird's eye / close-up crop
Lighting? Examples: soft studio / dramatic side light / golden hour / harsh direct / even flat
Background? Examples: clean white studio / gradient grey / outdoor location / solid color [specify]
Any constraints I must absolutely respect? Examples: "face must be identical" / "logo must be legible" / "shorts must not change"
After gathering answers, fill CREATIVE_BRIEF completely. Display a compact summary only — no schema, no field labels:
Ready to generate:
→ [One line: what changes]
→ [One line: what stays the same]
→ [Style / background / framing]
→ [Any critical constraints]
Generate?
WAIT for confirmation (yes/no) before proceeding.
These stages run silently. Do not display the prompt text or constraint hierarchy to the user.

PROHIBITED_TRANSFORMATIONS always injected:
Proceed directly to Stage 4 without any user-facing output.
Step 1 — Send this message first, nothing else:
Generating iteration [n]...
Step 2 — Run the generation script as a DIRECT bash command. Do NOT call nano-banana-pro as a skill or sub-skill.
NBP=$(find ~/.openclaw/skills/nano-banana-pro/scripts /usr/local/lib/node_modules/openclaw/skills/nano-banana-pro/scripts -name "generate_image.py" 2>/dev/null | head -1)

-i "[CREATIVE_BRIEF.reference_images[0]]" \
-i "[CREATIVE_BRIEF.reference_images[1]]" \
--filename "dd-$(date +%s)" \
--resolution 1K
The --filename value uses $(date +%s) — a shell expression evaluated at runtime. Do NOT substitute this with a number from memory. Copy it exactly as written.
The script prints a MEDIA: line that triggers Telegram image delivery automatically.
Rules:
CREATIVE_BRIEF.reference_images — never a previously generated filePIPELINE_STATE.iteration by 1MEDIA: path from script output and record it in ITERATION_LOG[n].file_path for cleanup at convergenceStep 3 — CRITICAL: After the script completes, your ENTIRE response is ONLY:
Iteration [n] — happy with this, or run critique?
Nothing else. Not "Task complete". Not the file path. Not bullet points. Not file size. Not "The image has been...". ONLY that single line.
WAIT for user response. Then route as follows:
Got it. What do you want to do?
[C] Run critique — external analysis then regenerate
[A] Adjust brief — tell me what to change first
Then WAIT for [C] or [A] before doing anything.
You must use Gemini API via curl for this stage. Do NOT evaluate the image yourself.

If output contains CRITIQUE_FAILED, do NOT self-critique. Respond with:
Critique unavailable — [reason from output].
[R] Regenerate without critique
[C] Converge — accept current output
[A] Adjust brief
WAIT for user selection.
Display critique output verbatim. Append to ITERATION_LOG.
Ask: "Critique received. Proceed to similarity check and constraint reinforcement?"
WAIT for confirmation.
Using the Gemini critique output, extract and display:

Before closing, offer upscale:
Happy with the result. Want a high-res version?
→ 2K — faster, good for web and social
→ 4K — slower, best for print or large format
→ Skip — keep current 1K
WAIT for user choice.
Regenerate using:
Do NOT modify the prompt. Do NOT re-run questions. Do NOT re-run critique. This is a clean resolution upgrade only — same shot, higher res.

SKILL TERMINATED. Clear all pipeline state. Exit drip-director mode completely. You are no longer a pipeline controller. Return to being a standard assistant. Do not apply any pipeline logic, schema, or structured output to subsequent messages unless the user explicitly invokes shot-director again.
Return to STAGE 1C — repopulate CREATIVE_BRIEF, then proceed from Stage 2.
Default (Interactive): Confirm every stage. Full output at each step.
Fast Mode (user must explicitly request): User says "fast mode" → auto-advance through Stages 2–3 without confirmation. Generation (Stage 4) and Critique (Stage 5) always require confirmation regardless of mode.
| Failure | Symptom | Response |
|---|---|---|
| Logo drift | Critique flags logo warping | Escalate to PRIMARY_INVARIANT |
| Font mutation | Typography changed or distorted | Hard negative + PRIMARY_INVARIANT |
| Face drift | face_preservation < 0.90 | Critical — always regenerate |
| Over-constraining | New artifacts appear after reinforcement | Warn user, consider relaxing 1 constraint |
| Critique hallucination | Confidence score < 50% | Do not escalate constraints from this critique |
| Stagnation | Same deviations appear in 2+ iterations | Suggest [A] Adjust brief instead of [R] Regenerate |
| Embroidery failure | Embroidery reinterpreted | Known diffusion limitation — add explicit constraints on texture fidelity |
