What it does

Grill Design is an agent skill from will-ness-ai/skills. Converge on a frontend look through rounds of prototypes and grilling verdicts. Use when the user wants to iterate on UI/visual taste against concrete variants, or a wayfinder prototype ticket names this skill.

Its SKILL.md is about 250 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Agent Workflows, covering Requirements gathering. The repository describes itself as: Skills for building high quality software. The licence is MIT.

When your agent uses it

  • The user wants to iterate on UI/visual taste against concrete variants
  • A wayfinder prototype ticket names this skill

Example prompts

  • “/grill-design”

What it can do on your machine

Read from SKILL.md and the folder at commit 71d8909. 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

Grill Design loads about 254 tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 114 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~56
When it runs · the whole SKILL.md, loaded when a task matches
~254

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.

description
Converge on a frontend look through rounds of prototypes and grilling verdicts. Use when the user wants to iterate on UI/visual taste against concrete variants, or a wayfinder prototype ticket names this skill.

Run a /grilling session, using the /prototype skill — each question is asked with prototypes, not words:

  • Each round, build 5 radically different prototypes of the current design question into one live mocked app: one standalone HTML file (Artifact tool), updated in place each round.
  • A floating bottom-right draggable picker names each design; ←/→ arrows switch between them, restyling the mocked app live. When the design has meaningful states (an inbox: full vs empty), add picker buttons that toggle the mock between them.
  • The grilling walks down the visual design tree, each verdict zooming in one level: the overall design, then component groups, then individual components — until the user has designed the entire feature in detail.
