Use this skill when exploring a fuzzy idea, thinking through a concept from first principles, stress-testing assumptions, or crystallizing what you're actually trying to build before committing to a plan. Load when asked to brainstorm, when a problem statement is vague, or when the user is saying "I'm thinking about..." rather than "build this."
Use this skill when verifying that implementation work meets acceptance criteria, reviewing code for security vulnerabilities, assessing code quality and stability, or producing a formal review report. Load when conducting QA, security audits, or acceptance testing against a defined spec.
Use this skill when verifying a build, preparing a deployment, creating pull requests, running health checks, or managing a release. Load when the task is to get code from "merged" to "running in production" — or to confirm it is ready to be merged.
Use this skill when writing implementation plans, spec files, or step-by-step execution plans for engineers or sub-agents. Load when translating an architecture document and requirements into a concrete, ordered execution plan where each step must be self-contained and independently executable.
Use this skill when writing product requirements documents, defining acceptance criteria, or translating research and user needs into structured, testable specifications. Load when the task is to define what the system must do — not how — including functional requirements, non-functional requirements, user stories, acceptance criteria, and scope boundaries.
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.

Generate a single image per request via a provider script. Default provider is nano-banana-pro unless the user asks for OpenAI.
If the user does not provide a prompt, you must generate a random prompt about a cartoon octopus image and pass it to the script.
Providers:
nano-banana-pro → src/skills/image-generation/providers/nano-banana-pro.pyopenai → src/skills/image-generation/providers/openai-image-generation.pyRun scripts using an absolute path (do NOT cd to the skill directory first). Always run from the user's working directory so outputs land where they are working.
If the user does not specify an API key, assume the runtime already has secrets loaded (e.g., via framework secret storage or environment loading). Do NOT read .env directly.
If you need to run a command in a shell that already loads environment variables, you can use:
bash -lc "set -a; source .env; set +a; <command>"
Generate new image (nano-banana-pro):
uv run /absolute/path/to/src/skills/image-generation/providers/nano-banana-pro.py --prompt "your image description" --filename "output-name.png" [--resolution 1K|2K|4K] [--api-key KEY]
Edit existing image (nano-banana-pro):
uv run /absolute/path/to/src/skills/image-generation/providers/nano-banana-pro.py --prompt "editing instructions" --filename "output-name.png" --input-image "path/to/input.png" [--resolution 1K|2K|4K] [--api-key KEY]
Generate new image (openai):

Goal: fast iteration without burning time on 4K until the prompt is correct.
uv run /absolute/path/to/src/skills/image-generation/providers/nano-banana-pro.py --prompt "<draft prompt>" --filename "yyyy-mm-dd-hh-mm-ss-draft.png" --resolution 1K--input-image for every iteration until you’re happy.uv run /absolute/path/to/src/skills/image-generation/providers/nano-banana-pro.py --prompt "<final prompt>" --filename "yyyy-mm-dd-hh-mm-ss-final.png" --resolution 4KNano Banana Pro (resolution):
