Goal

An opinionated AI-native workflow for evolving modern Java Enterprise SDLC practices through reusable Skills, Agents, Commands & MCP servers.

What is a Plinch?

A plinth represents the solid foundation or platform used to support statues or artworks in art and sculpture. It served as a structural and symbolic foundation for columns, statues, and entire temple podiums. Romans inherited the idea from Greek architecture but expanded its use to emphasize monumentality, hierarchy, and imperial power.

See it in action

Ask your agent:

Use @110-java-maven-best-practices to review this Maven project.
Explain the findings, apply the approved improvements, and validate the build.

The skill guides the agent through a structured Maven review while keeping you in control of proposed changes.

Migrating from legacy rules

Current System prompts/rules are deprecated and will be removed in v0.17.0. If you still use them, review the release 0.14.0 article.

Choose your path

Commands compose the workflow by routing work to the right agent and skill set:

Plan

Turn an idea into an actionable change with user stories, GitHub Issues or Jira, ADRs, diagrams, AI plan mode, and OpenSpec.

Compliance (Alpha)

Review Java systems, AI models, and how GenAI tools are used across applications and delivery pipelines for regulation-aware engineering controls, evidence, and qualified owner handoffs spanning AI, data, security, product, platform, market, and governance. These skills support engineering awareness and do not provide legal advice.

Note: This set of skills could be a good complement for the future OWASP EU Compliance MCP.

Project Components

The project generates a set of deliverables at the end of any iteration.

Compatibility

This project is compatible with any tool that supports Commands, Agents, Skills, MCP Servers and AGENTS.md.

Skill Validations

Every push runs the following validation checks in CI Builds to keep documentation and generated skills correct, consistent, and secure:

Limitations

Lack of determinism

From the outset, be aware that results from interactions with these Skills and agents are not deterministic because of how the models behave, but you can mitigate that with clear goals and validation checkpoints.

Not all models behave in the same way

Some interactive skills require Premium models for interactive use; otherw
