Is the Senior Frontend skill free?

Yes. The skill itself is free from ComposioHQ/awesome-claude-plugins. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Senior Frontend SkillProof Score?

8.0/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 7/10, docs & honesty 3/5.

How do I install Senior Frontend?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Senior Frontend with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Works
Score: 8.0/10
Tested: Jul 20, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 52f221e

Fetched the repo tree (repo redirects to composio-community/awesome-claude-plugins, default branch master) and read the raw SKILL.md + plugin.json in full. It's a single self-contained cheat-sheet (frontmatter with name+description parses; no scripts or relative links to break; no exfiltration/base64/secrets). Measured output on an accessible-close-button + useDebounce task: the skill reliably forced type="button", aria-label, aria-hidden icon, focus-visible ring, and the cn() convention that my baseline dropped — a real, moderate a11y/structure win. Docked docs to 3/5 because the SKILL.md and plugin.json advertise a "scaffolder" and "component generator" with CLI-flag tables as "automation tools," but the repo ships only SKILL.md — those are prompt conventions, not runnable tooling.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What Senior Frontend does

A pure-prompt reference skill for React, Next.js, TypeScript, and Tailwind: component patterns, a useDebounce hook, bundle-swap suggestions, Server/Client component discipline, and an accessibility checklist. Triggers when building React components, optimizing Next.js, analyzing bundle size, or reviewing frontend code. Self-contained (no scripts), so it works the moment it's copied in.

How to install Senior Frontend

Copy the `senior-frontend/skills/senior-frontend/` directory into your Claude skills folder (or install the plugin from the repo). Pure prompt content — no dependencies, scripts, or external CLI to run.

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.
