Run, write, generate, record, save, persist, and synthesize agent retrospectives and lessons learned after completing tasks. Self-assess session quality, identify mistakes, extract reusable patterns, and update persistent LESSONS.md files using the retrieve-verify loop. Auto-trigger setup: install OpenCode plugin hooks, Claude Code Stop hooks, and Cline TaskComplete hooks so the retro prompt fires automatically when all todos complete — but the agent always asks the user 1–2 targeted questions before writing (retros never resolve silently). Works with session_read (OpenCode), context-window reconstruction (Claude Code, Cursor, Gemini CLI), and compaction pipelines. Use when finishing a task, at session end, when asked to reflect, review, debrief, or write a post-mortem, or when setting up automatic retro triggers.

Write resource requests, limits, and topologySpreadConstraints for production. Use when deploying containers or microservices to GKE, configuring load balancers, setting up autoscaling, writing health checks, managing environment configs, troubleshooting pod issues, or integrating Workload Identity for GCP API access.

Write, create, and generate Spring Boot tests with JUnit 5, MockMvc, Mockito, and Testcontainers. Implement unit tests (pure Mockito), slice tests (@WebMvcTest, @DataJpaTest, @JsonTest), and integration tests (@SpringBootTest). Use when testing controllers, repositories, services, REST APIs, or setting up test fixtures. Covers test organization, mocking strategies, test data builders, and debugging test failures.

Write, create, generate, debug, and fix Angular unit tests, component tests, service tests, and e2e tests. Vitest is the default test runner for Angular v21+ (also supports Jest, Jasmine, Cypress, Playwright, TestBed). Use when testing components, services, signals, observables, DOM interactions, or mocking dependencies.

Create, write, generate, edit, update, and format markdown documentation (README, CHANGELOG, research notes, plans, guides, tutorials).

Use when writing .md files, documenting code, creating project docs, saving research findings, building README files, managing TODO lists, or generating any markdown content.

Build, configure, deploy, monitor, and optimize reactive APIs and services with Spring WebFlux, Project Reactor (Mono, Flux), WebClient, and reactive operators. Capabilities include MDC context propagation (ContextRegistry, Hooks.enableAutomaticContextPropagation), WebClient configuration (timeouts, error handling, retry), reactive operator chains (flatMap, switchIfEmpty, zip), and blocking detection with BlockHound. Configure Schedulers, WebTestClient, deferContextual, and contextWrite for production.
