Error Boundary

Q: What is a Claude Code skill and how does the Error Boundary 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. Error Boundary is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the General category.

Use when designing or reviewing React error boundaries: what an error boundary catches (rendering errors, lifecycle errors, constructor errors) and what it does not (event handler errors, async errors, SSR errors, errors in the boundary itself), why React still requires class components for error boundaries, how to place boundaries by granularity (page / feature / leaf), how error boundaries pair with Suspense, the reset-and-recover pattern (resetKeys, error.reset), the Next.js error.tsx route-segment convention, and how to integrate boundaries with error reporting (Sentry, observability). Covers React 18+ and Next.js App Router. Do NOT use for Suspense boundary placement (use suspense-patterns), for general error-handling discipline (try/catch in async code, validation errors), for backend error contracts (use api-design), or for observability infrastructure (use error-tracking).

How Error Boundary fits the catalog

Error Boundary sits in the General category under the hello-world-templates 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 Error Boundary safe to install?

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

Installing & verifying

Installing Error Boundary writes its SKILL.md to ~/.claude/skills/error-boundary/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 — error-boundary should appear by name.

What Error Boundary 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: ~2,243 words, substantial — top of the catalog distribution.

When to reach for it

There are 10 related skills in General — a two-minute scan of the alternatives usually confirms whether Error Boundary is the right pick.

What this skill does

Error Boundary is a community-contributed Claude Code skill in the hello-world-templates sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/error-boundary/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when designing or reviewing React error boundaries: what an error boundary catches (rendering errors, lifecycle errors, constructor errors) and what it does not (event handler errors, async errors, SSR errors, errors in the boundary itself), why React still requires class components for error boundaries, how to place boundaries by granularity (page / feature / leaf), how error boundaries pair with Suspense, the reset-and-recover pattern (resetKeys, error.reset), the Next.
