What it does
UI Mockup is an agent skill from greenfield-inc/Pane. Create three UI mockup options per round, then refine the user's favorite until they approve one. Works from screenshots of the current product or from agreed references for something new, with whatever tools are available (an image model, HTML/CSS in a browser, or a wireframe). Use for "mock this up," "UI mockup," or "show me what this would look like" for interfaces. Saves the approved design with the ticket or brief.
Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `metadata/codex.yaml`).
It sits in Frontend & Design, covering UI design. The repository describes itself as: Terminal-first, open-source AI agent manager for any CLI agent (agent agnostic), any OS (mac, windows, linux). The Open-Source Agentic Development Environment for running…
When your agent uses it
- Show me what this would look like for interfaces
- Tasks that involve UI design
Example prompts
- “mock this up,”
- “UI mockup,”
- “show me what this would look like”
- “/ui-mockup”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- An image model with editing (edits a screenshot, or generates from
- HTML and CSS in a browser: always available where a browser is. Rebuild
- A wireframe (ASCII or a quick SVG): for early structure questions when
What it can do on your machine
Read from SKILL.md and the folder at commit 0c471a3. 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
UI Mockup loads about 959 tokens when it runs. Until then it costs about 108 tokens; SKILL.md has 537 words of instructions outside code blocks.
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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 537 words (~959 tokens).
“Show the person what an interface could look like before anyone builds it. Match the product's visual language when there is a product, and make every option easy to compare.”
