sketch

sketch is a skill for Claude Code, Codex from NousResearch/hermes-agent. It costs 18 tokens per session (2,402 once invoked), scanned A, original, MIT.

A method for making temporary interactive HTML mockups of a screen or interface. It produces two or three design variations so they can be compared before production code is written.

In plain words
What is it for?
Use it to explore a screen, compare alternate layouts, test a UI idea, or review several design directions before committing to one.
Why use it?
It helps settle the layout and visual direction early, before time is spent building the final implementation. The mockups are disposable rather than intended for release.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sketch scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 221 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Sketch

Use this skill when the user wants to see a design direction before committing to one — exploring a UI/UX idea as disposable HTML mockups. The point is to generate 2-3 interactive variants so the user can compare visual directions side-by-side, not to produce shippable code.

Load this when the user says things like "sketch this screen", "show me what X could look like", "compare layout A vs B", "give me 2-3 takes on this UI", "let me see some variants", "mockup this before I build".

When NOT to use this

  • User wants a production component — use claude-design or build it properly
  • User wants a polished one-off HTML artifact (landing page, deck) — claude-design
  • User wants a diagram — excalidraw, architecture-diagram
  • The design is already locked — just build it

If the user has the full GSD system installed

If gsd-sketch shows up as a sibling skill (installed via npx get-shit-done-cc --hermes), you can use gsd-sketch for the fuller workflow: persistent .planning/sketches/ with MANIFEST, frontier mode analysis, consistency audits across past sketches, and integration with the rest of GSD. This skill is the lightweight standalone version — one-off sketching without the state machinery.

Note: The upstream GSD project (gsd-build/get-shit-done) is archived / no longer maintained on GitHub. The npm package (get-shit-done-cc) still installs, but treat it as an archived community project — this standalone sketch skill is the maintained path and needs nothing extra.

Core method

intake  →  variants  →  head-to-head  →  pick winner (or iterate)

1. Intake (skip if the user already gave you enough)

Before generating variants, get three things — one question at a time, not all at once:

  1. Feel. "What should this feel like? Adjectives, emotions, a vibe." — "calm, editorial, like Linear" tells you more than "minimal".
  2. References. "What apps, sites, or products capture the feel you're imagining?" — actual references beat abstract descriptions.
  3. Core action. "What's the single most important thing a user does on this screen?" — the variants should all serve this well; if they don't, they're just decoration.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
