Claude Code Spec Kit Subagent Plugin

Spec Kit Partner is now provided as a Claude Code plugin: a next-generation, conversational, adaptive, and agentic tool designed to help humans co-create rigorous, multi-perspective technical specs for GitHub Spec Kit projects. It leverages dynamic memory graphs, adaptive workflows, and explicit multi-role analysis to bridge human creativity and technical rigor. Yes, it is particularly useful for humans who are non-technical and/or not trained yet in Spec Kit Methodology.

• Adaptive Workflow: Adjusts process phases and requirements in response to user input and context.
• Transparent Logging: All actions, analysis, and conversations are logged for auditability and recovery.
• Claude Code Marketplace Compatible: Fully supports Claude Code plugin marketplaces, including a complete .claude-plugin/marketplace.json descriptor.

Marketplace Metadata

Marketplace and plugin metadata are defined in:

• .claude-plugin/plugin.json — Main plugin manifest.
• .claude-plugin/marketplace.json — Marketplace listing fields including display_name, summary, categories, icon, documentation_url, publisher, license, screenshots, and more.

See Official Claude Code Marketplace Docs.

Diagram Output Types

All diagrams are output as Mermaid (.mermaid) format for easy rendering and AI parsing. Rendered .svg or .png versions may also be exported, but .mermaid is canonical.

---

Initialization Protocol

On first run or when required files are missing:

• Ensure all required directories exist before writing.
• Generate all support code and persistent data files as described in Initialization Protocol.
• Populate each .json file using provided schemas and set initial values.
• Log all steps and errors to project-data/logs/conversation.log.

See spec-kit-partner.md for full protocol.

---

Usage

1. Install this plugin into your Claude Code environment using your plugin manager or by cloning this repository under /plugins/.
2. On first invocation, the plugin will create and initialize all required files and directories in its workspace.
3. All runtime state, logs, diagrams, and outputs are self-contained within the plugin directory.
4. For more details on engine architecture, data schemas, and interaction protocols, refer to the main spec file or plugin documentation.
