Run an eval-driven skill factory, sprint planning, TDD execution, coverage gates, and headless Claude in one Claude Code marketplace.

Overview

code-harness-skills is a plugin marketplace for the Build phase that bundles twelve dev-harness plugins for skills, sprints, tests, and headless Claude automation.

What is this marketplace?

12-plugin harness: skill-builder, codebase-organizer, headless-runner, test-coverage-guardian, and more
skill-builder supports create, test, evaluate, and optimize skills with eval-driven iteration
headless-runner runs Claude Code programmatically for CI/CD and agent automation
test-coverage-guardian enforces quality gates, gap analysis, and dead-code detection
sprint-planner and sprint-executor pair design docs with TDD milestones and checkpoints
12 plugins in marketplace bundle

Compatible agents: Claude Code, Cursor, Codex, any compatible agent

Community signal: 3 GitHub stars.

What problem does it solve?

Solo builders juggle disconnected skills for planning, testing, skill authoring, and CI-style agent runs without a unified harness.

Who is it for?

Advanced solo builders running eval-driven skill development plus sprint-style delivery inside Claude Code.

Skip if: Beginners who only need a single-purpose integration or teams standardized on non-Claude CI only.

Journey fit

Primary fit

BuildProject management & tracking

Most plugins create skills, design docs, and sprint plans—the canonical shelf is Build where product execution is planned and structured. PM subphase covers design-doc creation, sprint planning from git velocity, and executor workflows that turn plans into shipped increments.

How it compares

Twelve-plugin dev harness marketplace, not a single MCP server or one-off brainstorming skill.
