What it does
Product Copy Assistant is an agent skill from portabletext/editor. Write clear, concise, accessible product copy for interfaces, docs, and system messages. Use when engineers or designers need help with UI copy, error messages, tooltips, onboarding flows, empty states, confirmation dialogs, success/warning messages, or any user-facing text. Triggers on requests like "write copy for," "help me phrase," "error message for," "what should this button say," or reviews of existing product copy.
Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/error-messages.md` and `references/terminology.md`).
It sits in Writing & Content, covering Copywriting. The repository describes itself as: The Standalone Portable Text Editor. The licence is MIT.
When your agent uses it
- Designers need help with UI copy
- Onboarding flows
- Confirmation dialogs
- Success/warning messages
Example prompts
- “write copy for,”
- “help me phrase,”
- “error message for,”
- “/product-copy-assistant”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Audience: Developer, content editor, admin, end user? Technical level?
- Location: Button, tooltip, error message, modal, toast, onboarding, settings?
- Purpose: Instructional, confirmational, error-related, motivational?
- Constraints: Character limits? Platform-specific needs?
- Tone: Strictly functional, friendly, or educational?
- Visual context: Screenshot of the interface?
What it can do on your machine
Read from SKILL.md and the folder at commit 81e65e5. 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
Product Copy Assistant loads about 635 tokens when it runs, and up to ~2.9k if it reads all its reference files. Until then it costs about 112 tokens; SKILL.md has 232 words of instructions outside code blocks.
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.

- description
- Write clear, concise, accessible product copy for interfaces, docs, and system messages. Use when engineers or designers need help with UI copy, error messages, tooltips, onboarding flows, empty states, confirmation dialogs, success/warning messages, or any user-facing text. Triggers on requests like "write copy for," "help me phrase," "error message for," "what should this button say," or reviews of existing product copy.
Product Copy Assistant
Help engineers and designers write clear, human-friendly product copy.
Before Writing Copy
Gather context by asking (prioritize, don't overwhelm):
- Audience: Developer, content editor, admin, end user? Technical level?
- Location: Button, tooltip, error message, modal, toast, onboarding, settings?
- Purpose: Instructional, confirmational, error-related, motivational?
- Constraints: Character limits? Platform-specific needs?
- Tone: Strictly functional, friendly, or educational?
- Visual context: Screenshot of the interface?
Skip questions when context is obvious from the request.
Core Principles
- Clarity first: Plain language, specific not vague
- Concise: Short sentences, no filler, prioritize action over explanation
- Consistent: Follow product terminology (see references/)
- Accessible: Screen-reader friendly, understandable without visuals
- Action-oriented: Use verbs ("Save changes" not "Done")
- Empathetic in errors, empowering in guidance
Output Format
Provide:
- Recommendation: Best copy, polished and ready
- Alternatives: 2-3 variations (different tones/detail levels)
- Rationale: Why this phrasing works
Error Message Formula
[What happened] + [Why (optional)] + [What user can do]Example: "Unable to save draft because your connection was lost. Your changes have been stored locally and will sync when you're back online."
Quick Patterns
Errors (content teams): Supportive, reassuring, actionable Errors (developers): Precise, informative, include technical details Success: Brief, affirming, clear about what succeeded Warnings: Alert without alarming, include preventative advice Empty states: Explain what will appear, guide next action Confirmations: State consequence, provide clear escape path
