Server Actions Design

Q: What is a Claude Code skill and how does the Server Actions Design skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Server Actions Design is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category.

Use when designing or reviewing Server Actions: the 'use server' directive contract, how a server-side function becomes invokable from the browser without an API route, form integration via the `action` attribute, the React 19 hooks useActionState / useFormStatus, progressive enhancement (works without JS), server-side validation and authorization as mandatory rather than optional, revalidation primitives (revalidatePath, revalidateTag, redirect), error handling and bound arguments, and the security boundary that makes Server Actions a public endpoint despite their function-like syntax. Covers Next.js App Router as the canonical implementation. Do NOT use for read-path data fetching with RSC (use server-components-design), for the broader 'use client' / 'use server' boundary semantics (use client-server-boundary), for designing externally-facing API contracts (use api-design), or for form UX patterns at the component level (use form-ux-architecture).

How Server Actions Design fits the catalog

Server Actions Design sits in the Security category under the zero-trust sub-topic in the ClaudSkills catalog. There are 10 related skills indexed alongside it; comparing a few before installing usually reveals which fits your workflow best.

Is Server Actions Design safe to install?

A free static scan against the OWASP Agentic Skills Top 10 found no risk patterns in Server Actions Design’s SKILL.md — no data-exfiltration, prompt-injection, or unexpected-execution signatures. The full security scan is below.

Installing & verifying

Installing Server Actions Design writes its SKILL.md to ~/.claude/skills/server-actions-design/SKILL.md; Claude Code discovers it automatically on the next session — no restart flag needed. It declares no allowed-tools restriction, so it inherits your session’s existing tool access rather than narrowing it. To confirm it loaded, ask Claude to list its available skills — server-actions-design should appear by name.

What Server Actions Design needs to run

External services: The SKILL.md references pricing, quota, or rate limits — it likely calls a paid or rate-limited API. Check the source before wiring it into unattended automation.
Scope discipline: Declares explicit “when not to use” boundaries — safer than average to hand to an autonomous agent, which is less likely to over-apply it.
Worked code: 5 copy-paste code blocks in the body.
Depth: ~2,204 words, substantial — top of the catalog distribution.

When to reach for it
