Claude Code Harness
Generate structured harness blueprints for agentic runtimes inspired by Claude Code patterns before you wire tools, hooks, and guardrails.
Overview
claude-code-harness is a plugin marketplace for the build phase that packages one skill for generating agent harness blueprints modeled on Claude Code runtime patterns.
What is this marketplace?
- Single-skill marketplace plugin focused on harness blueprint generation
- Derived from Claude Code–style runtime patterns (version 0.1.0)
- Strict=false plugin packaging for flexible local adoption
- Public harness design skill for agentic systems architecture
- 1-plugin bundle—minimal surface, deep agent-runtime focus
- Marketplace bundles exactly 1 plugin (claude-code-harness).
- Metadata version 0.1.0; plugin strict mode is false.
- Single skill path: ./skills/claude-code-harness.
Community signal: 10 GitHub stars.
What problem does it solve?
Solo builders duct-tape skills and MCP servers without a documented harness, so agent behavior drifts and every new tool breaks the loop.
Who is it for?
Indie developers designing or refactoring a Claude Code–class agent host who want a written harness plan before more plugins land.
Skip if: Teams that only need finished app features with no custom agent runtime, or builders who want a full multi-plugin SDLC suite in one install.
What do I get? / Deliverables
After you register the marketplace, you can produce a harness blueprint that anchors skills, tools, and runtime rules before implementation sprawls.
- Harness blueprint describing agent loop, tooling, and guardrails
- Clear mapping from Claude Code–style patterns to your stack
- Foundation document for subsequent skill and MCP integration work

Journey fit
Harness design is canonical on the build shelf because it defines how your coding agent runs before you ship features on top of it. agent-tooling is where solo builders pick skills, MCP wiring, and runtime loops—not generic backend APIs.
How it compares
Agent harness design skill bundle, not a curated multi-plugin dev workflow marketplace.
Common Questions / FAQ
Who is Claude Code Harness for?
It is for solo and small-team builders architecting agentic coding systems who need a harness blueprint before stacking more skills or MCP integrations.
When should I use Claude Code Harness?
Use it early in build—or when re-scoping validate—whenever you are defining how your agent starts, stops, uses tools, and enforces guardrails.
How do I add Claude Code Harness to my agent?
Register the dadwadw233/Claude Code Harness Claude marketplace in Claude Code, install the Claude Code Harness plugin, then invoke the packaged harness skill from your agent session.
