composition-patterns

composition-patterns is a skill for Claude Code from Team-Deepiri/deepiri-axiom. It costs 43 tokens per session (558 once invoked), scanned A, original, Apache-2.0.

A set of React design patterns for building flexible, reusable user-interface components. React is a JavaScript library for user interfaces; these patterns cover compound components, shared state providers, render props, and React 19 features.

In plain words
What is it for?
It helps refactor React components, design component libraries, manage shared state between related components, and review reusable component APIs.
Why use it?
It helps avoid components overloaded with many on-or-off settings, which can make their APIs hard to understand and maintain. Instead, related parts can be combined into clearer component structures.

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-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 11d 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.

What it actually says

Composition patterns (Vercel)

Flexible, maintainable React components via composition — not boolean prop sprawl.

Source: vercel-labs/agent-skills (composition-patterns). MIT.

When to apply

  • Components with many boolean props
  • Reusable component libraries
  • Flexible component APIs
  • Compound components / context providers
  • Architecture review of React UI

Rule categories by priority

Priority Category Impact Prefix
1 Component Architecture HIGH architecture-
2 State Management MEDIUM state-
3 Implementation Patterns MEDIUM patterns-
4 React 19 APIs MEDIUM react19-

Quick reference

1. Architecture (HIGH)

  • architecture-avoid-boolean-props — don't customize via booleans; compose
  • architecture-compound-components — shared context for complex components

2. State (MEDIUM)

  • state-decouple-implementation — only the provider knows state plumbing
  • state-context-interface — generic state / actions / meta for DI
  • state-lift-state — state in providers for sibling access

3. Patterns (MEDIUM)

  • patterns-explicit-variants — variant components over boolean modes
  • patterns-children-over-render-props — children over renderX props

4. React 19+ (MEDIUM)

Skip if on React 18 or earlier.

  • react19-no-forwardref — no forwardRef; prefer React 19 patterns (use() vs useContext())

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.
