$ /plugin marketplace update mhattingpete-claude-skills

Then run /reload-plugins. Marketplaces refresh from the source repo at startup.

When to use it

You want a bundle of software-engineering skills (planning, git-pushing, test-fixing, review) plus a plan-implementer agent in one install.
You run bulk or codebase-wide transformations (10+ files) and want local Python execution instead of burning tokens reading/editing each file.
You need to generate self-contained HTML visuals — architecture diagrams, flowcharts, dashboards, timelines, technical docs.
You want code-operations skills (line-precise transfer, bulk refactor, file analysis) ported from code-copy-mcp.

Commands & flags

/plugin marketplace add mhattingpete/claude-skills-marketplace: Add the marketplace; installs the engineering-workflow plugin (skills + plan-implementer agent).
/plugin marketplace add mhattingpete/claude-skills-marketplace/code-operations-plugin: Install just the code-operations plugin (code-execution, code-transfer, code-refactor, file-operations).
code-execution: Run Python locally with marketplace API access for 90%+ token savings on bulk/codebase-wide work.
feature-planning: Break a feature request into discrete tasks executed by the plan-implementer (Haiku) agent.
architecture-diagram-creator: Generate self-contained HTML architecture diagrams with data flows and deployment info.
~/.claude/plugins/marketplaces/mhattingpete-claude-skills/execution-runtime/setup.sh: One-command install of the FastMCP execution-runtime server after adding the marketplace.

How to use it

Add the marketplace, then install the plugins you want:

/plugin marketplace add mhattingpete/claude-skills-marketplace

This installs the engineering-workflow-plugin (skills + plan-implementer agent). Install individual plugins by appending the path:

/plugin marketplace add mhattingpete/claude-skills-marketplace/visual-documentation-plugin
/plugin marketplace add mhattingpete/claude-skills-marketplace/productivity-skills-plugin
/plugin marketplace add mhattingpete/claude-skills-marketplace/code-operations-plugin

For the token-saving execution runtime, run its setup after installing:

~/.claude/plugins/marketplaces/mhattingpete-claude-skills/execution-runtime/setup.sh

Skills are model-invoked: phrasing like "refactor 50 files to the new API" auto-triggers code-refactor in execution mode; "add user authentication" triggers feature-planning.

Why it earns its place

Bundles 17 skills across four cohesive plugins plus a Haiku-backed plan-implementer agent, so one marketplace add covers planning, git, testing, review, refactoring, and HTML docs. Its standout feature is the execution-runtime, which implements Anthropic's code-execution-with-MCP pattern to run Python locally and cut bulk-operation token use by 90-99% (the README cites 25K to 600 tokens on a 50-file rename). Apache-2.0, actively maintained, by an author shipping several MCP/agent projects (personal-ai-os, agent-composer, outlook-mcp).
