A skill for writing the small pieces of text used in interfaces, such as button labels, error messages, empty states, and notifications. It follows a defined casual-but-polite voice and tone.

Use it to create or revise UX microcopy for buttons, errors, empty screens, success messages, and other short interface text.

It helps make interface messages clear, consistent, helpful, and focused on what the user can do next.

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.

Model	Per session	Once invoked
Fable 5	$0.00029	$0.00932
Opus 5	$0.00015	$0.00466
Sonnet 5	$0.00006	$0.00186
Haiku 4.5	$0.00003	$0.00093

Security

Grade A, and why

ss-copy 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 5d 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 — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.

UX Microcopy Generator

Registry-first artifact boundary

When .styleseed/project.json and .styleseed/artifacts/index.json exist, resolve the requested artifact ID first, then read only .styleseed/bundles/<artifact-id>.md and .styleseed/manifests/<artifact-id>.json. Never fall back to the global legacy bundle for a registry project. Legacy projects may use .styleseed/effective-rules.md only when no registry exists.

When NOT to use

For long-form content (blog posts, docs, marketing pages) — out of scope
For full feedback state design (not just text) → use /ss-feedback
For brand voice/tone definition itself — this skill consumes a voice spec, doesn't create it
For translations to non-English languages — single-language only

Context: $0 Description: $ARGUMENTS

Read engine/UX-WRITING.md first — it's the rule set this skill applies: buttons name the action (not "Submit"), errors help instead of blame, empty states invite, money copy stays calm, one term per concept. Korean/CJK projects: see §W8 for the clear-calm-human "Toss feel" (존댓말 일관성, 사용자 관점 "내 계좌", 군더더기 빼기).

Instructions

Read the design language reference:
- DESIGN-LANGUAGE.md sections on Microcopy Tone Guide and UX Writing
Apply the voice principles:

Tone Rules

Casual but polite: Friendly, not robotic. Like talking to a helpful friend.
Active voice: "We saved your changes" not "Your changes have been saved"
Positive framing: "Free shipping on orders over $30" not "Orders under $30 have shipping fees"
Plain language: "Send money" not "Initiate transfer"
Concise: Every word must earn its place

Copy Patterns by Context

Button Labels (CTA)

Format: [Action verb] + [Object] (optional)
Good: "Place order", "Get started", "Save changes", "Try again"
Bad:  "Submit", "OK", "Click here", "Proceed to next step"

One primary CTA per screen
Label must clearly describe what happens next
Max 3 words for primary CTA

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.
