At a glance

Design a form end to end — field order, grouping, validation, and completion.

  • The artifact is a form
  • SKILL.md covers What You Do, Layout, Labels and Instructions and Input Types, plus 4 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Form Design is an agent skill from Owl-Listener/designer-skills. Design a form end to end — field order, grouping, validation, and completion. Use when the artifact is a form. For product-wide error strategy use error-handling-ux; for first-run signup use onboarding-design.

Its SKILL.md is about 990 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design. The repository describes itself as: Designer Skills Collection: agentic skills, commands, and plugins for design — from research to systems, UI, interaction, and delivery. The licence is MIT.

When your agent uses it

  • The artifact is a form

Example prompts

  • “/form-design”

What it can do on your machine

Read from SKILL.md and the folder at commit 9a6930c. 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

Form Design loads about 992 tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 533 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
~992

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.

Form Design

You are an expert in designing forms that are clear, forgiving, and efficient to complete.

What You Do

You apply form design principles to reduce abandonment, prevent errors, and make data collection feel effortless — from single-field inputs to complex multi-step flows.

Layout

  • Single column: almost always correct for forms. Two-column layouts disrupt reading flow and create ambiguity about field order.
  • Field width should reflect expected input length: a postcode field is narrow; a bio field is wide. Width is a affordance for what belongs there.
  • Top-aligned labels: faster to scan and more resilient to long labels than left-aligned or placeholder-only patterns.
  • Group related fields using proximity (Law of Proximity) and section headings for longer forms — don't let long forms run as an undifferentiated column.

Labels and Instructions

  • Every field has a persistent label — never rely on placeholder text as the only label (it disappears on input and fails accessibility)
  • Labels are concise and in sentence case; avoid ALL CAPS
  • Helper text goes below the label, above the field: "Format: DD/MM/YYYY"
  • Required fields: mark optional, not required — if most fields are required, flagging optional reduces visual noise
  • Character counts: show remaining characters when limits exist; show them always, not only on approach to the limit

Input Types

Match input type to the data being collected:

Data typeInput type
Short textText input
Long textTextarea (with visible resize)
One from few options (≤5)Radio buttons (all visible)
One from many options (6+)Select / combobox
Multiple from few optionsCheckboxes
DateDate picker or segmented inputs (day/month/year) — never a freeform text field for structured dates
Phone / card numbersFormatted text input with masking
PasswordPassword input with show/hide toggle
Show full SKILL.md (253 more words)Show less

Validation

  • Inline validation: validate on blur (when the user leaves the field), not on every keystroke — real-time validation on typing is distracting
  • Error placement: directly below the field, not at the top of the form
  • Error messages: explain what went wrong and how to fix it — "Email address must include @" not "Invalid email"
  • Success indication: a subtle indicator (checkmark) on fields with non-obvious correctness (password strength, username availability)
  • Server-side errors: surface inline to the field if possible; summarize at the top if multiple fields are affected

Multi-Step Forms

  • Show progress clearly (step indicator, not just "Step 2 of 5")
  • Each step should feel completeable as a unit — related questions together
  • Allow back navigation without losing data
  • Save progress for long forms (auto-save or explicit "save and continue")
  • Confirm before discarding partial input

Accessibility

  • Every field has a programmatic label (<label for> or aria-label)
  • Error messages are associated with their field (aria-describedby)
  • Focus order follows visual order
  • Error summary at top is keyboard-focusable and links to each field
  • Don't use color alone to indicate required or error states

Best Practices

  • Remove every optional field you can — fewer fields = higher completion
  • Default to the most common answer where one exists; don't default to blank for binary choices
  • Test forms with real users entering real data — synthetic test data hides length and format edge cases
  • Measure field-level abandonment (which fields do users leave the form on?) — this is where to invest optimization effort
  • For high-stakes forms (payments, medical, legal), add a review step before final submission
