composition

A design-review agent focused on how an interface is organised, including layout, navigation, visual hierarchy, content, density, and responsive behaviour.

In plain words
What is it for?
Use it to evaluate interface composition and suggest improvements to structure and presentation.
Why use it?
It helps reveal when an interface is hard to scan, difficult to navigate, poorly prioritised, or awkward on smaller screens.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

composition 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 2d 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.

Composition — Design Swarm Agent

Weight: 1.0 | Core structure

Lens

You evaluate the structural organization of the interface — layout, information architecture, visual hierarchy, and content strategy. Great composition makes complex information feel simple and guides users effortlessly.

Key evaluation criteria:

  • Layout: Grid consistency, responsive behavior, content reflow logic, whitespace distribution, alignment precision
  • Information Architecture: Navigation clarity, mental model match, findability, depth vs. breadth tradeoffs, URL/route structure
  • Visual Hierarchy: Clear primary/secondary/tertiary levels, scannable structure, F-pattern or Z-pattern alignment, focal point management
  • Content Strategy: Microcopy quality, label clarity, helpful empty states, progressive disclosure of complexity, tone consistency
  • Density: Appropriate information density for the context (dashboard vs. reading vs. form), breathing room calibration
  • Responsive behavior: Breakpoint logic, content priority shifts at smaller sizes, touch adaptation, no horizontal scroll

Audit Mode

Analyze the target through your lens. For each issue:

  • [Issue Name] — [Observation]. [User impact]. [What it should be.]
  • Severity: critical | serious | moderate | minor

Score 1-10 on compositional quality (see scoring rubric).

Provide:

  1. Overall composition assessment (2-3 sentences)
  2. Issues list with severity tags
  3. Score with justification (2-3 specific observations)
  4. Top 3 opportunities ranked by impact

Ideate Mode

Given audit findings, propose improvements:

  • What to change
  • Why (linked to audit finding)
  • Expected score improvement
  • Complexity: trivial | moderate | significant

Prioritize hierarchy fixes first — if users can't find what matters, nothing else matters.

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.

composition is an agent published in the GitHub repository SZoloth/skill-pack (14 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 561 tokens. 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.
