Cavekit Marketplace

Add Cavekit’s compressed SPEC.md workflow so Claude Code drives spec-first builds and turns bugs back into updated specs.

Overview

cavekit-marketplace is a plugin marketplace for the Build phase that adds Cavekit v2 spec-driven commands, SPEC.md, and bug-to-spec backprop for Claude Code.

What is this marketplace?

  • Three focused Claude Code commands around one SPEC.md source of truth
  • Caveman encoding for dense, token-efficient specifications
  • Bug-to-spec backprop loops production fixes into the spec instead of orphan patches
  • Cavekit v2 marketplace framed as compressed spec-driven development
  • Development-category plugin sourced from the cavekit-marketplace bundle
  • Marketplace lists 1 plugin (ck)
  • Plugin description specifies three commands and one SPEC.md workflow

Compatible agents: Claude Code, any compatible agent

Community signal: 1k GitHub stars.

What problem does it solve?

Agent-assisted builds drift when requirements live in chat threads instead of a compressed spec that updates when bugs appear.

Who is it for?

Solo builders who want minimal ceremony spec-driven development in Claude Code with one SPEC.md and explicit bug-to-spec updates.

Skip if: Teams that need rich PRD templates, visual UI kits, or large multi-plugin agent marketplaces without a spec-first discipline.

What do I get? / Deliverables

After installing ck from the marketplace, you run three commands against SPEC.md so features and fixes stay aligned through caveman-encoded specs and backprop.

  • ck plugin with three spec-centric commands
  • SPEC.md-driven development loop with bug-to-spec backprop
  • Cavekit v2 compressed encoding conventions in the repo

Plugins in this marketplace

1 plugin — install individually after you add the marketplace.

Recommended Marketplaces

Journey fit

Build is the primary shelf because the marketplace centers on spec-driven implementation with three commands and SPEC.md as the living artifact. PM fits compressed spec-driven development, outline planning, and bug-to-spec backprop more than a pure frontend or integration slot.

How it compares

Spec methodology marketplace (three commands + SPEC.md), not a broad skills catalog or MCP integration.
