A curated list of 6 high-value Claude Skills covering frontend aesthetics, office document handling, web search, and persistent memory, with install links and use cases — ideal for Claude Code and OpenClaw users.

6 Must-Install Claude Skills: Double Your AI Agent's Capabilities

Skills are capability extension units for AI Agents like Claude Code and OpenClaw — essentially a description file that tells the Agent what to do in specific scenarios. The 6 Skills below cover high-frequency needs including frontend development, office documents, web access, and memory management, all with install links included.

1. Frontend Design: Removing the "AI Look" from AI-Generated Frontends

Built by Anthropic officially, currently ranked #1 on the Claude plugin marketplace, with more downloads than Superpowers.

Problem: AI-generated frontend pages all tend to look the same — blue-purple gradients, the Inter font, white cards. Frontend Design changes this with hard constraints.

Core mechanism:

  • Decide on a complete aesthetic direction before writing any code (minimalism, retro-futurism, etc.)
  • Ban overused fonts like Inter, Roboto, and Arial
  • Forbid the classic AI aesthetic of purple gradients on white backgrounds
  • Keep typography, whitespace, and motion unified around the chosen direction

The weaker the model, the more noticeable the improvement from Frontend Design. Especially recommended when doing frontend work with Haiku or smaller models.

2. The Office Four-Pack: docx / xlsx / pdf / pptx

Four separate Skills that handle reading and writing for Word, Excel, PDF, and PowerPoint respectively.

Problem: By default, Claude frequently loses formatting, runs into encoding errors, and fails to parse tables correctly when working with Office documents. These four Skills package up the proper handling logic for each format, so the Agent takes the correct path every time it's invoked.

Best for: Batch-processing contracts and reports, reading Excel data for analysis, extracting structured information from PDFs, and automatically generating or modifying slide decks.

Install links (Anthropic official plugin pages):

Problem: Claude's default web access often returns outdated information or fails to fetch pages in complex scenarios. Web Access provides more reliable web retrieval and content-extraction logic, supports summarizing content across multiple pages, and reduces "unable to access this link" errors.

4. PUA Skill: Stopping the AI from Giving Up

Problem: When facing complex or ambiguous tasks, Claude tends to give dismissive answers — "this issue is quite complicated," "we recommend consulting a professional." The PUA Skill adjusts the Agent's system behavior so it keeps trying when things get hard instead of giving up outright.

Note: This Skill makes the Agent more aggressive in executing tasks; when it involves file operations, code modifications, and the like, use it together with permission controls.

5. Claude-mem: Persistent Memory

Problem: Claude's context is wiped when a session ends, and the next one starts from scratch. Claude-mem persists important information to local files and loads it automatically at the start of the next session.

Typical uses: Remembering coding style preferences, saving project architecture decisions, and maintaining user information across sessions.

Claude-mem ships with a local web interface running at localhost:37777, where you can see in the browser exactly what it remembered and when.

Privacy control: tag anything you don't want remembered (passwords, keys, etc.) and it will skip it automatically.

6. Skill Creator: From Consumer to Creator

The first five Skills solve general-purpose problems, while Skill Creator solves a different thing entirely: how to build your own custom Skill.

Core value: It helps you package your own workflows, experience, and business rules into a reusable Skill file. You don't need to know how to code — describe your requirements clearly, and it generates the Skill definition file; install it into your Agent and it just works.

Real-world case: A non-developer wrapped their server's admin access into a Skill wholesale. From then on, every member of the team could have the Agent manage the server through that Skill, with no one needing to know ops.

If you're setting up Skills for the first time, install them in this order:

  1. Skill Creator: Install this first — every later customization need depends on it
  2. Web Access: Useful in almost every scenario
  3. Claude-mem: Builds cross-session memory; the earlier you install it, the more valuable it is
  4. Frontend Design: If you do frontend work
  5. The office four-pack: Pick whichever ones you actually need
  6. PUA Skill: Install once you notice the Agent dodging problems repeatedly

The first five Skills are answers someone else thought through for you; Skill Creator gives you the ability to create answers of your own.
