A Claude Code marketplace handles the AI Unified Process (AIUP) workflow end-to-end. An IntelliJ plugin keeps the resulting specs and tests connected as you code.
A marketplace of Claude Code plugins designed to drive the AI Unified Process workflow: gathering requirements, modeling entities, specifying use cases, and generating implementation and tests.
Includes the stack-agnostic aiup-core plugin and the technology-specific aiup-vaadin-jooq plugin for Java web applications.
The AI Unified Process Navigator is a standalone IntelliJ plugin that links @UseCase annotated test methods to their UC-XXX-*.md specifications via gutter icons, and back from the spec to the test.
Works independently of Claude Code, but pairs naturally with the marketplace plugins: generate specs and tests with Claude Code, then traverse them inside IntelliJ.
A stack-agnostic core for requirements engineering, paired with a technology-specific plugin for Vaadin + jOOQ implementation.
Stack-agnostic methodology plugin with templates for requirements-driven development. Works with any technology stack.

Get started with the Claude Code marketplace plugins in just a few steps
Agent Skills (SKILL.md) is now an open standard. The same skill files in this marketplace run natively — with auto-triggering by description — in OpenAI Codex CLI, Cursor, GitHub Copilot, Gemini CLI, and OpenCode. Install them with Tessl, or clone the repo, drop the skill folders into your tool's skills directory, and configure the MCP servers.
Tessl is an agent-agnostic package manager for skills: it installs versioned skills and wires the MCP servers into the correct per-agent directory for whichever coding agent it detects. Both plugins are published to the Tessl registry as aiup/aiup-core and aiup/aiup-vaadin-jooq.
Installed plugins land in .tessl/plugins/ and are tracked in tessl.json, so versions are pinned and reproducible across your team.
Clone the marketplace repo, then copy or symlink the skill folders into your tool's skills directory and configure the MCP servers from each plugin's .mcp.json in your tool's MCP config.
Trigger skills the same way you would in Claude Code — say "write requirements" or invoke /requirements. The file outputs are identical regardless of tool, so the chain composes even if you mix tools across steps.
Native SKILL.md support — drop into ~/.codex/skills/ or .agents/skills/.
Native Agent Skills since Cursor 2.4 — drop into project-local .cursor/skills/.
Understands Claude Code's /plugin marketplace commands directly — install the plugins the same way as in Claude Code, skills and MCP included.
Native SKILL.md support — drop into .gemini/skills/ or ~/.gemini/skills/.
Native skill support — also scans .claude/skills/ and .agents/skills/, so skills installed for Claude Code are picked up without copying.
A separate IntelliJ plugin that links use case specifications to their tests, independent of Claude Code
Click the gutter icon on a @UseCase annotated test method to jump to its matching UC-XXX-*.md specification, and back again from the spec header to the test.
Markdown headers and business rule references in your specs become clickable, keeping requirements and tests in sync as you work.
Open IntelliJ IDEA, go to Settings → Plugins → Marketplace, search for "AI Unified Process Navigator", and click Install. No Claude Code required.
