langchain4j-agentic Tessl tile

A Tessl tile giving AI coding agents authoritative context for building and demoing Java AI agent systems with the langchain4j-agentic module. Combines official-docs API reference (langchain4j/docs/docs/tutorials/agents.md) with demo-building guidance, integrations, and runnable templates.

The centerpiece is the typed-verdict Custom Strategy (illustrated as CriticResult — a user-defined inter-agent object, not a framework type) — see docs/custom-strategy-critic-result.md.

Develop locally

tessl tile lint .              # validate structure & content
tessl install file:.           # install from filesystem into the current repo
tessl tile pack --output ./dist .

Publish

Set a real workspace in tile.json (name: "<workspace>/langchain4j-agentic"), then tessl tile publish.

Notes

• langchain4j-agentic is experimental; the BOM does not manage the beta artifacts — pin them independently.
• Custom patterns (goal-oriented, P2P, voting) ship in langchain4j-agentic-patterns.
• The WIP/langchain4j-agentic-research/ folder holds the original demo research this tile was reconciled from; it is not part of the published tile.
