What it does

Use UI Kit is an agent skill from tetherto/pearpass-app-mobile. Use whenever creating or editing UI in this repo — React Native components, modals, bottom sheets, forms, buttons, inputs, typography, styling, icons, or any .tsx/.jsx work. The repo uses @tetherto/pearpass-lib-ui-kit as the single source for UI primitives; do not roll custom ones. Load this before suggesting any UI change to src/components, src/containers, or src/screens.

Its SKILL.md is about 3.3k 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, covering Design systems, React components and Cross-platform mobile apps. It works with React Native. The repository describes itself as: PearPass is an open-source, privacy-first password manager with peer-to-peer syncing and end-to-end encryption.

When your agent uses it

  • Editing UI in this repo — React Native components
  • Any .tsx/.jsx work

Example prompts

  • “/use-ui-kit”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Check the catalog below before creating any component. If it exists in the kit, use it — never wrap or reimplement.
  2. All new UI goes through @tetherto/pearpass-lib-ui-kit. New .tsx/.jsx files must import from the kit, not from src/libComponents/. That…
  3. Never add variants under src/libComponents/ (ButtonThin, ButtonPrimary, ButtonLittle, InputPasswordPearPass, etc.). The kit's Button takes…
  4. Style with tokens. useTheme() + rawTokens. No hardcoded hex colors or design-system spacing.
  5. Icons come from the kit. @tetherto/pearpass-lib-ui-kit/icons has 530 icons. Do not add new SVGs under src/.
  6. If the kit lacks something you need, stop and ask. Don't silently roll a custom component.

What it can do on your machine

Read from SKILL.md and the folder at commit c6afff8. 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 (its code samples are javascript and typescript).

    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

Use UI Kit loads about 3.3k tokens when it runs. Until then it costs about 97 tokens; SKILL.md has 1,198 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~97
When it runs · the whole SKILL.md, loaded when a task matches
~3.3k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,198 words (~3,273 tokens).

“This is the React Native + Expo mobile app for PearPass, written in JavaScript + TypeScript. UI is built on the shared component library @tetherto/pearpass-lib-ui-kit.”
