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" },
