Distinctive, intentional visual design for any UI being built or reshaped - aesthetic direction, typography, layout, motion and interface copy that does not read as a templated default. Use on every ticket that changes what users see.
We split this skill-frontend-design.mdc into the rules it gives an agent
1 rule. About 0 are common, 0 are distinctive, and 1 is very specific to this project.

≈ “Common” is an estimate: at least 1 in 5 of the 6,350 Cursor rule files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

# Frontend design
Read and follow `skills/frontend-design/UPSTREAM.md`: Anthropic's frontend-design skill, copied
unchanged from https://github.com/anthropics/claude-plugins-official
(`plugins/frontend-design/skills/frontend-design/SKILL.md`) on 2026-10-14, under the Apache
License 2.0 in `skills/frontend-design/LICENSE.txt`. `tools/checks/upstream_check.py` fails if
the copy is edited.
## How it fits this template
- **The brief is the spec.** The design brief the upstream skill asks for is
`docs/work/<id>/spec.md` and `ux.md`, plus `project.toml [product]` (audience, regions). The
product designer writes `ux.md` itself, from the spec; where the founder has set a direction,
follow it ("the brief's own words always win").
- **Plan before code, in the work folder.** The design plan the upstream skill asks for (palette,
type, layout, principles) goes in `docs/work/<id>/ux.md` or beside it, so `qa` and later
tickets can see it.
- **The quality floor is a requirement**, not a nicety: responsive to phone width, visible
keyboard focus, reduced motion respected, contrast to the bar in `agents/product-designer.md`.
- **Copy follows the project's style rules** (`project.toml [style]`), including the banned
characters, which the upstream text itself uses in places.
- **Fonts and images** are checked for licence before use, and their cost if any is sourced
(`skills/verified-claims/`).
Where files are headingNew Cursor rule files have more rules about planning and tracking tasks, and fewer about code style.
Of the Cursor rule files we read, the 3,978 first seen in the last six months, against the older ones: the kind of rule that gained most share, and the kind that lost most. About files like this in general, not this one, and an estimate, since a kind is a pattern in the words.
In this repository120 other files it gives its agents.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
