Kiln

Raw code refined into polished design.

Kiln is a marketplace of Claude Code plugins for code quality and intelligent tooling. Design plugins encode platform-specific guidelines as machine-enforceable rules. Performance plugins distill expert optimization knowledge into actionable guidance. API plugins provide structured guides for web research and data enrichment APIs.

Adding a New Plugin

Each plugin lives in plugins/<name>/ as a self-contained Claude Code plugin:

plugins/<name>/
├── .claude-plugin/
│   └── plugin.json          # Plugin manifest (name, version, description)
├── agents/                  # Autonomous review agents
├── commands/                # Slash commands (/review, /generate, etc.)
├── skills/                  # Skills with progressive disclosure
│   └── <name>/
│       ├── SKILL.md
│       └── references/
└── README.md

Then register it in .claude-plugin/marketplace.json at the repo root:

{
  "name": "<name>",
  "source": "./plugins/<name>",
  "description": "...",
  "version": "0.1.0",
  "author": { "name": "timbo" },
  "category": "design",
