JVM and AI-agent developer tools

Alex Mondshain <alex.mondshain@gmail.com>

I build open-source tools that make developers' lives easier — byte-for-byte JVM ports of Go & Helm tooling, LLM-ready profiling, and self-learning Claude Code skills. Everything's on GitHub; the Java libraries publish to Maven Central under org.alexmond.

jvmlens JVM diagnostics your AI agent can actually read — a JFR recording becomes a few-hundred-token, source-attributed, LLM-ready diagnosis instead of a multi-MB jfr print dump. profiling · MCP · LLM-ready jhelm Native Java Helm — render charts and manage releases without the Go binary. Byte-for-byte across 346 real charts, now MCP-native. Built on gotmpl4j. kubernetes · helm · MCP alexmskills A curated Claude Code marketplace of self-learning skills and agents — a CLAUDE.md that prunes its own decisions, a delivery crew, a brainstorm panel, evolving roles, and a prompt coach that nudges you toward better prompts. claude code · self-learning UniTrack Self-hosted test & coverage tracking that explains why builds break — quality gate, flaky detection, failure clustering, polyglot coverage, GitHub PR checks. testing · coverage · self-hosted

Libraries and tools

gotmpl4j Pure-Java Go text/template + Sprig — no Go toolchain. Byte-for-byte parity across 1,305 of Go's own test cases. The engine under jhelm. go template · jvm gotmpl4j-spring-boot Spring Boot integration for gotmpl4j — starter, MVC/WebFlux ViewResolver, and Spring-context template functions. One branch per Spring Boot line, versioned to match. spring boot · go template notify4j Embeddable multi-channel notifications for Java/Spring Boot — Slack, Teams, Discord, Telegram, ntfy, PagerDuty… as Apprise-style URLs. No server to run. spring · notifications notify4j-spring-boot Spring Boot starter for notify4j — binds the notify4j.* properties and auto-configures the Notifications facade. One branch per Spring Boot line, versioned to match. spring boot · notifications UniAuth Spring Boot starter that puts OAuth2 / OIDC, SAML 2.0, LDAP and internal accounts behind one Spring Security filter chain — one login page, one uniauth.* configuration, and an optional approval gate. spring boot · security Config JSON Schema Auto-generate JSON Schema from your @ConfigurationProperties — IDE autocomplete and config validation in CI. spring boot Actuator Extensions A sensitive-data sanitizer plus extra health indicators (HTTP, port, manual) for better Spring Boot monitoring. spring · actuator Spring Boot Admin Extensions Extensions for Spring Boot Admin — an Environments page, a Live Metrics view, and a Redis event store that survives a Redis outage. One branch per Spring Boot line. spring boot admin · redis · vue JSupervisor supervisord for the JVM — process supervision with HTTP/TCP/Actuator/CLI health checks, log rotation, and a UI/REST/CLI. java · ops yj-schema-validator Validate YAML/JSON against JSON Schema (drafts 2019-09 / 2020-12) — colored / JSON / JUnit output for quick checks or CI gates. cli · ci Spring Boot Examples A hands-on hub of Spring Boot example projects — REST, security, JPA, OpenAPI, admin monitoring, and AI integrations. spring · learning
