shadcn-composition-and-trigger-patterns

shadcn-composition-and-trigger-patterns is a skill for Claude Code, Codex from andrewsrigom/agent-skills. It costs 63 tokens per session (735 once invoked), scanned A, original, MIT.

Guidance for combining shadcn/ui building blocks into complete interface features, such as dialogs, menus, popovers, and command panels. It explains how triggers and wrappers should work together.

In plain words
What is it for?
Use it when building reusable product interfaces with shadcn/ui, especially when handling trigger ownership, nested menus or dialogs, popovers, sheets, and command interfaces.
Why use it?
It helps prevent broken interactions, tangled properties, and too many unnecessary wrapper components when small interface pieces are combined.

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

shadcn-composition-and-trigger-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 2mo 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.

shadcn Composition And Trigger Patterns

Use this skill when the task is mostly about composing shadcn primitives into stable UI behavior.

Scope

  • asChild usage
  • trigger ownership and composability
  • dialog, dropdown, sheet, popover, and command-surface composition
  • local wrappers and boundaries
  • avoiding wrapper sprawl and prop soup

Routing cues

  • asChild, trigger composition, dialog triggers, dropdown menu actions, command surfaces, local wrappers, Radix composition behavior, or deciding how to own a reusable product surface -> use this skill
  • if the problem is really theme tokens or dark mode -> use shadcn-theming-tokens-and-dark-mode
  • if the problem is really field structure and validation flows -> use shadcn-forms-and-field-primitives

Default path

  1. Start from the copied component code and compose behavior locally.
  2. Use asChild when the trigger or interactive wrapper must preserve the existing element contract.
  3. Keep open state local unless multiple siblings truly need coordination.
  4. Extract a local product wrapper only after the interaction pattern repeats.
  5. Prefer a few stable composition patterns over a large library of speculative wrappers.

When to deviate

  • Lift state only when coordination or controlled behavior is clearly needed.
  • Build a stronger wrapper when repeated product usage needs one shared semantic contract.
  • Skip asChild when the default trigger element is already the right contract.

Guardrails

  • preserve semantics when composing triggers
  • do not hide simple component usage behind unnecessary wrappers
  • keep interaction ownership close to the surface that actually needs it
  • treat copied shadcn code as editable when behavior or accessibility needs adjustment

Avoid

  • wrapping every component immediately for “future flexibility”
  • stacking several interactive wrappers without thinking through focus and semantics
  • using asChild mechanically when the default trigger is already correct
  • creating giant prop bags to drive what should be small local composition decisions

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.
