# Brief: diagnosis-playbook-skills

## Background

The MVP Agent has trace persistence, evidence tools, verifier gates, and fixed diagnosis eval cases, but scenario-specific diagnosis procedures were still embedded in broad prompts and knowledge-base documents.

## Goal

Introduce versionable diagnosis playbook skills that agents can discover from a compact catalog and read on demand through a `read_skill` tool.

## Scope

- Six initial diagnosis playbooks: payment timeout, MySQL connection pool, Redis timeout, slow response, JVM memory risk, and AIOps alert.
- Classpath skill catalog loader.
- `read_skill` Spring AI tool.
- Prompt catalog injection for Chat and AIOps Planner/Executor paths.
- Focused tests.

## Non-goals

- No external API or database schema changes.
- No replacement of `lookup_knowledge`.
- No Verifier skill loading.
- No direct dependency on Java2AI `SkillsAgentHook` until local package names are verified.
