interaction-patterns

interaction-patterns is a skill for Claude Code from Bilal140202/the-lord-of-the-skills. It costs 48 tokens per session (1,706 once invoked), scanned A, original, MIT.

A structured review of an interface's usability and basic accessibility. It checks Nielsen's 10 usability guidelines plus keyboard access, visible focus, contrast, and motion-related WCAG checks.

In plain words
What is it for?
Use it to review a page, component, or complete user flow before release and produce findings with severity and suggested fixes.
Why use it?
It catches interaction and accessibility problems that automated scans or visual design reviews may overlook.

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

interaction-patterns 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 12d 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.

Interaction Patterns

Purpose

Walk a UI surface (a page, a component, or an end-to-end flow) against Nielsen's 10 usability heuristics and a WCAG 2.2 first-pass for the fast-to-check criteria — keyboard reachability, focus visibility, color contrast, and motion/animation. Produces a finding-by-finding report with severity and a remediation hint. Not a full a11y scan (see a11y-scan for tool-driven scanning); this is the structured-thinking pass that catches what tools miss.

Scope

In:

  • One target surface — page URL, component path, or flow description.
  • Nielsen's 10 heuristics, applied as a checklist.
  • WCAG 2.2 fast-check criteria: 2.1.1 (keyboard), 2.4.7 (focus visible), 1.4.3 / 1.4.11 (contrast), 2.3.3 (animation from interactions), 2.2.2 (pause / stop / hide).
  • A markdown report with severity tags and remediation hints.

Out:

  • Tool-driven a11y scanning (axe, Pa11y, Lighthouse) — that's a11y-scan.
  • Visual design critique (color palette, spacing system, brand cohesion) — that's mockup-review.
  • User research findings against real users — that's usability-review with a recruited cohort.

When to use

  • Before a feature ships, as a structured second-pass after design hand-off and before QA.
  • When a designer says "I think this flow is fine" and you want a reproducible heuristic walk to confirm.
  • For component-library primitives — every primitive should pass the full Nielsen + WCAG fast-check before adoption.
  • During a design-system upgrade, against the project's flagship flows, to catch interaction regressions.

When NOT to use

  • For a brand-new mockup with no behavior yet — use mockup-review first; this skill needs interaction states to evaluate.
  • As a substitute for the automated a11y-scan — heuristic eval finds different bugs than rule-based scanners. Run both.
  • For server-side / API-only changes. No UI, no heuristics.

Automated pass

There is no fully automated pass — heuristic evaluation is judgment work. The skill scaffolds the report and prompts the evaluator through each heuristic.

Changes

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.

interaction-patterns is a skill published in the GitHub repository Bilal140202/the-lord-of-the-skills (4 stars, last pushed 6d ago), licensed MIT. It adds 48 tokens to every session and 1,706 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 2026-08-31.
