What are Skills and Agents?

Skills are model-invoked capabilities that extend Claude Code's functionality. Unlike slash commands that require explicit user activation, Skills are automatically triggered by Claude based on context and the Skill's description.

Each Skill consists of a SKILL.md file with:

• YAML frontmatter (name, description, metadata)
• Detailed instructions for Claude
• Optional supporting files (scripts, templates, references)

Agents are specialized Claude instances that can be invoked by Claude to handle specific types of work. They run independently with their own context and can use different models optimized for their task.

Each Agent consists of an AGENT.md file with:

• YAML frontmatter (name, description, model selection)
• Specialized instructions and constraints
• Decision-making frameworks for their domain

Skills and Agents work together: Skills can orchestrate when to invoke Agents, and Agents can use Skills while executing their tasks.

🚀 NEW: Execution Runtime (90%+ Token Savings)

The marketplace now includes a code execution environment implementing the Anthropic code execution pattern. Instead of loading code through context, Claude executes Python locally with API access—achieving 90-99% token reduction for bulk operations.

Quick Benefits

✅ Massive token savings: Process 100 files with 1K tokens instead of 100K ✅ Faster operations: Local execution vs multiple API round-trips ✅ Stateful workflows: Resume multi-step refactoring across sessions ✅ Auto-secure: PII/secret masking, sandboxed execution

Setup (2 minutes)

# After installing marketplace plugin
~/.claude/plugins/marketplaces/mhattingpete-claude-skills/execution-runtime/setup.sh

When It Activates

Skills automatically use execution mode for:

• Bulk operations (10+ files)
• Complex multi-step workflows
• Iterative processing
• Codebase-wide analysis

Example: "Rename getUserData to fetchUserData in all Python files"

• Without execution: ~25,000 tokens (read/edit 50 files)
• With execution: ~600 tokens (script + summary) - 97.6% savings
