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.

The marketplace now includes a code execution environment implementing the [Anthropic code execution pattern](https://www.anthropic.com/engineering/code-execution-with-mcp). 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)

```bash

# 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

Install from Marketplace

```bash

# In Claude Code - installs the entire plugin with all skills and agents

/plugin marketplace add mhattingpete/claude-skills-marketplace

```

This installs the engineering-workflow-plugin which includes all skills and the plan-implementer agent.

To install individual plugins:

```bash

# Install only engineering workflows

/plugin marketplace add mhattingpete/claude-skills-marketplace/engineering-workflow-plugin

# Install only visual documentation

/plugin marketplace add mhattingpete/claude-skills-marketplace/visual-documentation-plugin

# Install only productivity skills

/plugin marketplace add mhattingpete/claude-skills-marketplace/productivity-skills-plugin

# Install only code operations

/plugin marketplace add mhattingpete/claude-skills-marketplace/code-operations-plugin

```

Engineering Workflow Plugin

Skills for common software engineering workflows including git operations, test fixing, code review implementation, and feature planning.

Visual Documentation Plugin

Skills for creating stunning visual HTML documentation with modern UI design, SVG diagrams, flowcharts, dashboards, timelines, and comprehensive project architecture diagrams.

[View Plugin Documentation →](visual-documentation-plugin/README.md)

Productivity Skills Plugin

Productivity and workflow optimization skills for analyzing usage patterns, auditing code quality, bootstrapping projects, and generating comprehensive documentation.

[View Plugin Documentation →](productivity-skills-plugin/README.md)

Code Operations Plugin

High-precision code manipulation operations including line-based insertion, bulk refactoring, and file analysis. Converted from [code-copy-mcp](https://github.com/mhattingpete/code-copy-mcp) to native Claude Code skills.

Feature Development

#### feature-planning

Break down feature requests into detailed, implementable plans with clear tasks that can be executed by the plan-implementer agent.

Activates when: User requests a new feature, enhancement, or complex change requiring planning.

Example usage:

• "Add user authentication"
• "Build a dashboard for analytics"
• "Plan how to implement export functionality"

Works with: plan-implementer agent for execution

---

Git & Version Control

#### git-pushing

Automatically stage, commit with conventional commit messages, and push changes to remote.

Activates when: User mentions pushing changes, committing work, or saving to remote.

Example usage:

• "Push these changes"
• "Commit and push to github"
• "Let's save this work"

---

Testing & Quality

#### test-fixing

Systematically identify and fix failing tests using smart error grouping strategies.

Activates when: User reports test failures, asks to fix tests, or wants test suite passin
