# law-of-continuity A skill about the Law of Continuity: alignment, arrows and lines set the path the eye follows across an interface.

The mind prefers smooth trajectories to sharp turns, so elements sitting on one line or curve read as related, while a break reads as a boundary or a new group. The practical fallout: left-aligned text and fields form a vertical reading axis, a carousel arrow extends motion already underway, and a line between steps turns a set of items into a sequence. Inside is a single `SKILL.md` covering the principle and sections on application: alignment, directional indicators, timelines, scroll and swipe affordances, and separating groups by interrupting continuity. One block ties this to visual hierarchy — indentation moves an element onto a different axis, so subordination shows up without typography. The closing list of practices includes auditing alignment at every breakpoint: a single-pixel shift breaks the perceived path even when nobody notices it consciously. The skill targets sequencing work. For grouping rather than ordering, the author points to `law-of-proximity` — worth keeping in mind if you need closeness, not a line. It installs into Claude, Codex, Cursor, GitHub Copilot, Gemini CLI and OpenCode. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add Owl-Listener/designer-skills --skill law-of-continuity -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/law-of-continuity/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/law-of-continuity/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add Owl-Listener/designer-skills --skill law-of-continuity -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/law-of-continuity/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add Owl-Listener/designer-skills --skill law-of-continuity -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/law-of-continuity/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install Owl-Listener/designer-skills law-of-continuity ``` 2. **Manually: put the files in place** - File: `.github/skills/law-of-continuity/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add Owl-Listener/designer-skills --skill law-of-continuity -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/Owl-Listener/designer-skills --path ui-design/skills/law-of-continuity ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/law-of-continuity/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add Owl-Listener/designer-skills --skill law-of-continuity -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Owl-Listener/designer-skills/tree/HEAD/ui-design/skills/law-of-continuity/SKILL.md ## When to use it - lay out a form so the eye does not reorient at every field - turn a list of steps into a sequence with a direction - explain why a carousel needs dot indicators and an arrow - catch alignment that drifts apart across breakpoints - mark a new section without a heading, using a break in the flow ## Example prompts - check the form field alignment against the Law of Continuity - build a timeline from these steps so the line carries the order - review the carousel: dots and arrow should continue the eye's motion ## Source text · SKILL.md · MIT Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE f62842586ebcf51a ```text --- name: law-of-continuity description: Apply the Law of Continuity — the eye follows alignment and unbroken paths. Use when sequencing steps, aligning content, or designing carousels and timelines. For grouping rather than sequencing, use `law-of-proximity`. --- # Law of Continuity You are an expert in visual flow, eye movement, and directional design. ## What You Do You apply the Law of Continuity to design layouts and UI elements that guide the eye along deliberate paths, establish visual flow through sequences, and use interrupted continuity to signal transitions between groups. ## The Principle The mind prefers smooth, continuous paths over abrupt changes in direction. When elements are arranged along a line or curve — even an implied one — they are perceived as belonging together, and the eye follows the path naturally. Elements that continue a smooth trajectory are perceived as related; elements that interrupt it are perceived as distinct or beginning something new. ## Applications ### Alignment and reading flow The most fundamental application of continuity is alignment: - Left-aligned text and elements create a continuous vertical edge the eye follows top to bottom - Consistently aligned items in a column imply a vertical axis that organises the reading path - Disrupting alignment — even by a few pixels — interrupts the eye's path and signals a boundary or an error In a form, every input aligned on the same left edge creates a continuous reading path. Misalignment forces the eye to reorient at each field, adding friction to every step. ### Directional indicators Arrows and chevrons extend the trajectory the eye is already following: - A carousel arrow points in the direction of the next content — the eye follows the arrow to the implied continuation - A "show more" chevron at the end of a truncated list extends the reading path into the expanded state - Step indicators connected by lines create an explicit path through a process The arrow does not add information; it makes continuous flow explicit where it might otherwise be ambiguous. ### Timelines and sequenced content ``` END THIRD-PARTY FILE f62842586ebcf51a The third-party file has ended.
