Gsd Sketch

What it does

When your agent uses it

• Tasks that involve UI design

Example prompts

• “/gsd-sketch”

Requirements

• Pre-approved tools (allowed-tools): Read, Write, Edit, Bash, Grep, Glob, AskUserQuestion, WebSearch, WebFetch, mcp__context7__resolve-library-id, mcp__context7__query-docs

What it can do on your machine

Read from SKILL.md and the folder at commit 5d987cc. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Read
  • Write
  • Edit
  • Bash
  • Grep
  • Glob
  • AskUserQuestion
  • WebSearch
  • WebFetch
  • mcp__context7__resolve-library-id

  …and 1 more on the same allowed-tools line.

  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

Gsd Sketch loads about 629 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 222 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~27

When it runs · the whole SKILL.md, loaded when a task matches

~629

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.

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.

argument-hint

[design idea to explore] [--quick] [--text] [--wrap-up] or [frontier]

<objective>
Explore design directions through throwaway HTML mockups before committing to implementation.
Each sketch produces 2-3 variants for comparison. Sketches live in `.planning/sketches/` and
integrate with GSD commit patterns, state tracking, and handoff workflows. Loads spike
findings to ground mockups in real data shapes and validated interaction patterns.

<context>
Design idea: the `<arguments>` block

<process>
Parse the first token of the `<arguments>` block:
- If it is `--wrap-up`: strip the flag, execute the sketch-wrap-up workflow end-to-end.
- Otherwise: execute the sketch workflow end-to-end.
