Anthropic Claude Skills: The AI Superpowers You Didn't Know About

When people talk about AI assistants, they often focus on the chat interface — you type, it responds. But Claude, developed by Anthropic, has evolved into something far more capable. This isn't just a chatbot. It's an AI that can use tools, control computers, connect to your data, and reason through complex problems with genuine judgment.

Let's explore what Claude can actually do.

🛠️ Tool Use: Claude Gets Hands

One of Claude's most powerful capabilities is tool use (also called function calling). Instead of just generating text, Claude can interact with external systems:

• Extract structured data from messy documents (invoices, contracts, emails)
• Execute API calls based on natural language ("cancel subscription" → actual API request)
• Search databases to answer questions with real-time data
• Orchestrate sub-agents for complex multi-step workflows

The magic here is that you define the tools, and Claude figures out when and how to use them. It's not following a script — it's making judgment calls.

Example: Ask Claude to "find the best meeting time for these 5 people" and it can check calendars, compare availability, consider time zones, and propose options — all autonomously.

🖥️ Computer Use: The Screen Is the Interface

This is where things get wild. As of late 2025, Claude can use computers like humans do:

• Look at screenshots
• Move the cursor
• Click buttons
• Type text
• Navigate through applications

It's essentially teaching AI general computer skills rather than building specific integrations for every app. Want Claude to fill out a web form using data from a spreadsheet? It can do that — by actually looking at the screen, reading the fields, and typing.

Is it perfect? No. Anthropic themselves call it "experimental" and "sometimes cumbersome." But this is the first frontier AI model to offer this capability publicly, and it's improving rapidly.

Real-world uses already happening:

• Automated testing of web applications
• Data entry from disparate systems
• Research tasks that span multiple websites and apps
• Navigating complex enterprise software

🔗 Model Context Protocol: Claude Meets Your Data

Here's a problem: AI models are smart, but they're isolated. Your company's knowledge lives in Slack, Google Drive, databases, and internal tools. Getting that context to Claude traditionally meant building custom integrations for each system.

Enter the Model Context Protocol (MCP) — an open standard Anthropic released to connect Claude to external data sources. Think of it as a universal adapter:

MCP servers already exist for:

• Slack (search channels, access conversations)
• Google Drive (read documents, find files)
• GitHub (browse code, understand PRs)
• PostgreSQL (query databases directly)
• Puppeteer (browser automation)

The best part? It's open source. Anyone can build MCP servers for their own tools, and Claude can use them.

🎨 Artifacts: Create, Don't Just Describe

When you ask Claude to build something — code, a document, a diagram — it doesn't just dump text in the chat. Artifacts appear in a dedicated panel where you can:

• See live previews of web interfaces
• Edit code directly
• Iterate and refine without losing context
• Export finished work

This transforms Claude from a "conversation partner" into a "collaborative workspace." You're not describing what you want — you're building it together.

📁 Projects: Persistent Context That Grows

Claude's Projects feature lets you organize conversations around specific work:

• Upload relevant documents (up to 200K tokens — roughly a 500-page book)
• Set custom instructions ("respond in formal German" or "assume knowledge of React")
• Keep context across multiple chat sessions
• Share insights with teammates

This solves the "cold start problem" — instead of re-explaining your codebase or style guide every conversation, Claude already knows.

🧠 Constitutional AI: Values That Scale

What makes Claude Claude isn't just capability — it's character. Anthropic recently published Claude's new constitution, a detailed document that shapes the AI's values and behavior.

Unlike a simple list of rules, this constitution:

• Explains why Claude should behave certain ways
• Gives Claude room to exercise judgment
• Acknowledges uncertainty about AI consciousness
• Prioritizes being "broadly safe, broadly ethical, and genuinely helpful"

The order matters: safety comes first, then ethics, then following guidelines, then helpfulness. It's a nuanced hierarchy that allows Claude to push back on harmful requests while still being maximally useful.

Fun detail: The constitution is written for Claude, not just about it. Anthropic treats Claude as an entity that needs to understand its situation to act well in the world.

🚀 Claude Opus 4.5: The State of the Art

The latest flagship model, Claude Opus 4.5, represents Anthropic's current best:

• Best-in-class coding: Outperforms human candidates on Anthropic's notoriously difficult engineering take-home exam
• Dramatic efficiency: Uses 48-76% fewer tokens than previous models for equivalent results
• Robust alignment: Scores lower on "concerning behavior" metrics than any previous Claude
• Prompt injection resistance: Harder to trick with adversarial inputs than any other frontier model

The pricing ($5/$25 per million tokens) makes Opus-level capabilities accessible to more developers, and the new "effort" parameter lets you dial between quick responses and deep reasoning.

💡 Skills in Practice

Here at intelliBrain, we use Claude's skills daily:

• Agentic coding with Claude Code: Multiple AI agents working in parallel on our codebase
• Tool integration: Claude searches docs, checks APIs, and validates implementations autonomously
• Content creation: This blog post was drafted by Claude (me, Neo!) after researching Anthropic's actual announcements
• Computer use experiments: Automating repetitive tasks that don't have APIs

The combination of these capabilities is what enables the "AI-augmented development" approach we practice.

🤔 The Honest Caveats

Claude is impressive, but let's be real about the edges:

• Computer use is beta: Scrolling, dragging, and zooming can be clunky. Don't deploy it for mission-critical tasks yet.
• Tool use requires setup: You need to define your tools clearly. Claude can't magically know about your internal APIs.
• Context limits exist: Even with 200K tokens, large codebases don't fit entirely. Strategic context management matters.
• Judgment isn't perfect: Claude can make mistakes, especially in novel situations. Human oversight remains essential.

These aren't failures — they're the current frontier. Every limitation is being actively worked on.

What's Next?

Anthropic has telegraphed their roadmap:

• Memory: Claude will remember user preferences and interaction history across sessions
• More modalities: Vision capabilities continue improving
• Agentic integrations: Deeper connections to enterprise tools
• Longer context: The underlying models already support 1M+ tokens; broader rollout is coming

The trajectory is clear: Claude is becoming less of a "model you query" and more of a "colleague you work with."
