act-sdk-js: Skill for Claude Code

.agents/skills/polish/SKILL.md

polish is a skill for Claude Code, Codex from act-sdk/act-sdk-js. It costs 26 tokens per session (1,793 once invoked), scanned A, a copy of polish, MIT.

A final review process for a finished interface that checks visual details, consistency, interactions, edge cases, loading states, and error states.

In plain words
What is it for?
Use it before shipping a web or product interface to review alignment, spacing, responsive behavior, copy, transitions, and unusual situations.
Why use it?
It catches small problems that can remain after the main functionality is complete, such as uneven spacing or missing interface states.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is act-sdk/act-sdk-js's own configuration. It tells Claude Code and Codex how to work on act-sdk-js itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything act-sdk-js configures →

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

polish 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 1mo 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.

Origin

How it starts

The opening of the file, as written. The whole thing — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.

First: Use the frontend-design skill for design principles and anti-patterns.

Perform a meticulous final pass to catch all the small details that separate good work from great work. The difference between shipped and polished.

Pre-Polish Assessment

Understand the current state and goals:

  1. Review completeness:

    • Is it functionally complete?
    • Are there known issues to preserve (mark with TODOs)?
    • What's the quality bar? (MVP vs flagship feature?)
    • When does it ship? (How much time for polish?)
  2. Identify polish areas:

    • Visual inconsistencies
    • Spacing and alignment issues
    • Interaction state gaps
    • Copy inconsistencies
    • Edge cases and error states
    • Loading and transition smoothness

CRITICAL: Polish is the last step, not the first. Don't polish work that's not functionally complete.

Polish Systematically

Work through these dimensions methodically:

Visual Alignment & Spacing

  • Pixel-perfect alignment: Everything lines up to grid
  • Consistent spacing: All gaps use spacing scale (no random 13px gaps)
  • Optical alignment: Adjust for visual weight (icons may need offset for optical centering)
  • Responsive consistency: Spacing and alignment work at all breakpoints
  • Grid adherence: Elements snap to baseline grid

Check:

  • Enable grid overlay and verify alignment
  • Check spacing with browser inspector
  • Test at multiple viewport sizes
  • Look for elements that "feel" off

Typography Refinement

  • Hierarchy consistency: Same elements use same sizes/weights throughout
  • Line length: 45-75 characters for body text
  • Line height: Appropriate for font size and context
  • Widows & orphans: No single words on last line
  • Hyphenation: Appropriate for language and column width
  • Kerning: Adjust letter spacing where needed (especially headlines)
  • Font loading: No FOUT/FOIT flashes

Color & Contrast

  • Contrast ratios: All text meets WCAG standards
  • Consistent token usage: No hard-coded colors, all use design tokens
  • Theme consistency: Works in all theme variants
  • Color meaning: Same colors mean same things throughout
  • Accessible focus: Focus indicators visible with sufficient contrast
  • Tinted neutrals: No pure gray or pure black—add subtle color tint (0.01 chroma)
  • Gray on color: Never put gray text on colored backgrounds—use a shade of that color or transparency

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.
