ontology-atlas: Skill for Claude Code

.agents/skills/responsive-sweep/SKILL.md

responsive-sweep is a skill for Claude Code, Codex from wlsdks/ontology-atlas. It costs 35 tokens per session (821 once invoked), scanned A, original, MIT.

A live responsive-layout check across phone, tablet, laptop, and wide-screen sizes using measured geometry, screenshots, and checks for covered elements.

In plain words
What is it for?
Use it to verify affected pages at defined viewport widths, measure element positions, detect occlusion with elementFromPoint, check bottom-tab spacing, and compare screenshots.
Why use it?
It catches defects that reading CSS alone can miss, such as overlapping browser chrome, incorrect breakpoint spacing, and navigation bars blocking content.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is wlsdks/ontology-atlas's own configuration. It tells Claude Code and Codex how to work on ontology-atlas itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ontology-atlas configures →

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.

Security

Grade A, and why

responsive-sweep 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 6d 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 — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Responsive sweep

Run only when pnpm design:route includes responsive-sweep. Use its scope: affected bands for a breakpoint-local change, the full matrix for a new surface or information architecture.

  • A breakpoint is a width where layout changes (md 768px, lg 1024px).
  • A rect is the measured getBoundingClientRect() geometry.
  • Chrome is the frame around content: header, toolbar, tab bar, and panels.

Static class reading missed three live defects: max-lg:pb-* lost to a later md:py-* rule at 768–1023px, three chrome rows overlapped by 79px, and a tab bar intercepted content. Only computed geometry and elementFromPoint proved them.

Width matrix

Viewport Band
600×900 phone/small portrait tablet; below md
768×1024 md boundary; side panels begin, tab bar remains
834×1112 11-inch tablet
1024×768 lg boundary; vertical navigation begins, tab bar leaves
1440×900 14-inch laptop; labels progressively compact
1920×1080 FHD
2560×1440 QHD

Use the router's returned bands. A local chrome or layout repair does not independently require the full matrix. If additional breakpoints are affected, update the change facts and use the resulting scope.

Loop at each width

  1. Resize and navigate to a URL reproducing the exact state, such as ?index=expanded or ?recent=auto. Set guides=off as a query parameter (use & when a query already exists); the first-run overlay otherwise captures every elementFromPoint. Use ?guides=reset only when testing the guide itself.
  2. Evaluate geometry:
    • collect fixed/floating rects and calculate their intersection in pixels;
    • probe the centre of every important control with document.elementFromPoint(cx, cy) and record the intercepting element;
    • below lg, compare the primary tab bar's top with the last scrolled content's bottom and every bottom-attached panel.
  3. Capture a screenshot for human evidence.

After the measured loop, capture at least the affected representative state with the computer-use capability and record app/window identity, accessibility owner, and saved screenshot path. Browser automation screenshots support the rect evidence but do not replace this capture.

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.

responsive-sweep is a skill published in the GitHub repository wlsdks/ontology-atlas (104 stars, last pushed today), licensed MIT. It adds 35 tokens to every session and 821 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
