nextjs-15Next.js 15 App Router patterns. An agent skill from Gentleman-Programming/Gentleman-Skills.
Nextjs 15 is an agent skill from Gentleman-Programming/Gentleman-Skills. Next.js 15 App Router patterns. Trigger: When working with Next.js - routing, Server Actions, data fetching.
Its SKILL.md is about 800 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with Next.js. The repository describes itself as: Community-driven AI agent skills for Claude Code, OpenCode, and other AI assistants. Curated patterns and community contributions. The licence is Apache-2.0.
Read from SKILL.md and the folder at commit c8036a3. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Nextjs 15 loads about 797 tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 28 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
The full file from Gentleman-Programming/Gentleman-Skills at commit c8036a3, republished under its Apache-2.0 licence (© Gentleman-Programming). 28 words, ~797 tokens.

Run `npx skills add Gentleman-Programming/Gentleman-Skills --skill nextjs-15 -a claude-code`. Or copy the skill folder (curated/nextjs-15 in Gentleman-Programming/Gentleman-Skills) into .claude/skills/nextjs-15 in your project. Claude Code loads it when a task matches its description.
Run `npx skills add Gentleman-Programming/Gentleman-Skills --skill nextjs-15 -a codex`. Or copy the skill folder (curated/nextjs-15 in Gentleman-Programming/Gentleman-Skills) into .agents/skills/nextjs-15 in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Gentleman-Programming/Gentleman-Skills --skill nextjs-15 -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/nextjs-15, .gemini/skills/nextjs-15, .github/skills/nextjs-15 and .opencode/skills/nextjs-15 in your project.
SKILL.md names no scripts, command-line tools or credentials: Nextjs 15 is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Nextjs 15 is published under the Apache-2.0 licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 797 tokens (SKILL.md is roughly 3.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Nextjs 15: Vercel Optimize Audit (vercel-labs/agent-skills, 32k stars), AI SDK (vercel-labs/ai-facts, 168 stars), Supabase Development and Debugging (supabase/agent-skills, 2.7k stars) and Chakra UI v3 Builder (chakra-ui/chakra-ui, 41k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
