design-form

design-form is a command for Claude Code from Owl-Listener/designer-skills. It costs 22 tokens per session (266 once invoked), scanned A, original, MIT.

A step-by-step method for designing a form, such as a sign-up or checkout form, from its fields to its completion and error messages. It covers how to group questions and guide people through them.

In plain words
What is it for?
Planning form structure, deciding which fields appear together, writing validation and error messages, and defining loading, progress, confirmation, and submission states.
Why use it?
It helps prevent forms from feeling confusing, overwhelming, or difficult to complete by planning choices, field order, validation, and feedback in advance.

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

design-form 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 11d 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.

What it actually says

/design-form

Design a form that minimises friction and guides users to successful completion.

Steps

  1. Structure — Define field order, grouping, and flow using form-design skill.
  2. Decision points — Reduce choices at each step to lower decision cost using hicks-law skill.
  3. Information chunks — Group related fields to fit working memory limits using millers-law skill.
  4. Targets — Size and position inputs and controls for fast, accurate interaction using fitts-law skill.
  5. Error prevention — Design inline validation and field constraints using error-handling-ux skill.
  6. Feedback — Specify confirmation, progress, and status messages using feedback-patterns skill.
  7. Loading — Design submission and processing states using loading-states skill.

Output

Form specification with field structure, grouping rationale, validation rules, error messages, and submission states. Consider following up with /error-flow to detail the full error handling model.

Changes

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.
