What it does

Nano Banana is an agent skill from social-media-skills/skills. Use to write great prompts for Nano Banana (Google's Gemini image model: Nano Banana Pro = Gemini 3 Pro Image) to generate or edit images for social media — the image-prompt-craft mini-skill. Run when the user wants a nano-banana / Gemini image prompt, an AI image for a post (quote graphic, carousel slide, thumbnail, infographic, product shot, ad creative), or conversational image editing. Reads brand-profile for brand colours/style. Strengths: best-in-class legible in-image text (route typography/layout-led…

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `evals/evals.json`, `references/examples.md` and `references/social-recipes.md`).

It sits in Media & Creative, covering Image generation, Image editing and Infographics. It works with Google Gemini and Midjourney. The repository describes itself as: 106 social media skills for AI agents - strategy, writing, video, design, platform growth, publishing, and analytics. Works with Claude, Cursor, OpenClaw, Hermes & 40+ agents. The licence is MIT.

When your agent uses it

  • Write great prompts for Nano Banana (Googles Gemini image model: Nano Banana Pro = Gemini 3 Pro Image) to generate
  • Edit images for social media — the image-prompt-craft mini-skill
  • Wants a nano-banana / Gemini image prompt
  • An AI image for a post (quote graphic

Example prompts

  • “s photoreal lane (Imagen deprecated); surreal art stays Midjourney”
  • “/nano-banana”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Read the brand + the job
  2. Write the prompt (natural language, not keyword spam)
  3. Use the superpowers deliberately
  4. Pick the recipe
  5. Verify, disclose, ship

What it can do on your machine

Read from SKILL.md and the folder at commit 6e30eeb. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Nano Banana loads about 1.6k tokens when it runs, and up to ~5.1k if it reads all its reference files. Until then it costs about 251 tokens; SKILL.md has 642 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~251
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Use to write great prompts for Nano Banana (Google's Gemini image model: Nano Banana Pro = Gemini 3 Pro Image) to generate or edit images for social media — the image-prompt-craft mini-skill. Run when the user wants a nano-banana / Gemini image prompt, an AI image for a post (quote graphic, carousel slide, thumbnail, infographic, product shot, ad creative), or conversational image editing. Reads brand-profile for brand colours/style. Strengths: best-in-class legible in-image text (route typography/layout-led design to ideogram), multi-image consistency, conversational editing, and Google's photoreal lane (Imagen deprecated); surreal art stays Midjourney's. Teaches prompt anatomy, the text-first approach, reference-image consistency, and per-platform aspect ratios. Honest: SynthID watermark + AI disclosure; never real identifiable people or copyrighted characters/logos; verify spelling/data. The API/connection and WoopSocial upload flow live in tools/integrations/nano-banana.md.

Nano Banana (image prompt craft)

Write prompts that get studio-quality images out of Nano Banana — Google's Gemini image model (Nano Banana Pro = Gemini 3 Pro Image; the Flash variant is faster/cheaper). This is the prompt-craft layer of a three-layer setup:

  • Connection/API (model IDs, auth, the generate → upload to WoopSocial Media → attach flow) → tools/integrations/nano-banana.md.
  • Prompt craft (this skill) → how to ask for the right image well.
  • In-skill application → e.g. carousel-writer's image-prompt-pack.

Fast-moving area — re-verify model names/capabilities quarterly.

Reach for Nano Banana when… (match the job)

Its real strengths: legible in-image text (best in class), multi-image/character consistency, conversational editing, and Search-grounded infographics. Reach elsewhere for typography/layout-led design (→ ideogram) or surreal/fine-art aesthetics (Midjourney). (Imagen, the former photoreal sibling, is deprecated — Gemini API shutdown Aug 17, 2026 — so Google-side photoreal work now lands here.) Don't default it to every job. (Details: references/when-and-how-to-prompt.md.)

Step 0 — Read the brand + the job

Load brand-profile.md (colours, visual style, do/don't). Identify the job (quote graphic / carousel / thumbnail / infographic / product shot / background / ad / edit) and the platform aspect ratio.

Step 1 — Write the prompt (natural language, not keyword spam)

Describe, don't pad. Include subject · composition/camera · action/context · lighting/atmosphere · style/medium · constraints + exact text. Drop "4k, masterpiece, trending on artstation" tokens — modern Gemini models reason over natural language. Bake in the brand palette/style. Set the aspect ratio. Iterate cheap at 1K, finalize at 2K/4K. See references/when-and-how-to-prompt.md.

Step 2 — Use the superpowers deliberately

  • Text: put the exact words in quotes + font + placement; settle the copy first (the text-first approach), keep it short, and verify the spelling in the output.
  • Consistency: use reference images and a locked style description; generate a set one at a time ("everything the same except X"); hold the aspect ratio; review for drift.
  • Editing: natural-language changes to a hero image for locale/seasonal/A-B variants.

See references/text-and-consistency.md.

Step 3 — Pick the recipe

Adapt a pattern for the job (quote graphic, carousel set, thumbnail, infographic, product/lifestyle, background, ad), with the right aspect ratio and brand grounding. See references/social-recipes.md.

Step 4 — Verify, disclose, ship

  • Verify rendered text and any infographic data before publishing (the model can misspell / misplace facts).
  • Disclose AI generation per platform/region (Meta "Made with AI", EU AI Act); every image carries a SynthID watermark (+ C2PA) — don't strip it or pass the image off as a non-AI photo.
  • Ship: generate per the integration guide → upload bytes to WoopSocial Media → attach to the post via scheduling-and-queue. WoopSocial doesn't generate images.

Quality bar — self-check

  • Did I match the tool to the job (and say when to use another model)?
  • Is the prompt natural-language and specific (subject/composition/lighting/style/text), brand- grounded, with the right aspect ratio?
  • For text: exact words in quotes + font + placement, copy-first, spelling verified?
  • For sets: references + locked style, one-at-a-time, reviewed for drift?
  • Did I handle SynthID + disclosure, verify text/data, and refuse real people / IP?
  • Did I point to tools/integrations/nano-banana.md for the API + WoopSocial flow (no claim that WoopSocial generates images)?

Edge cases & pushback

  • Photoreal headshot / surreal art → suggest the better-fit model; don't force Nano Banana.
  • "logo, 4k, masterpiece, trending…" → rewrite into a specific scene description; drop token spam.
  • Real person / copyrighted character / brand style → refuse; offer an original alternative.
  • "Post it as a normal photo" → SynthID + disclosure; don't disguise AI imagery.
  • Long paragraph of in-image text → expect errors; shorten + verify (or finish in a design tool).
  • "Generate it in WoopSocial" → WoopSocial doesn't generate; this skill prompts the model, then the image is uploaded to Media and attached.
  • tools/integrations/nano-banana.md — API/model IDs, auth, pricing, the upload-to-WoopSocial flow.
  • carousel-writer (image-prompt-pack), reels-script — consuming skills; ideogram — typography sibling.
  • brand-profile — the visual brand; caption-writer/hook-writer — the in-image copy.
  • scheduling-and-queue — attach the image to a post and publish.

References

  • references/when-and-how-to-prompt.md — when to reach for it vs other models, and the prompt anatomy.

  • references/examples.md — weak→strong prompts, a consistent carousel, an edit, and honest scope.
