jakarta-ee-enterprise-platform

jakarta-ee-enterprise-platform is a skill for Claude Code from vaquarkhan/Fullstack-development-agent-skills. It costs 51 tokens per session (618 once invoked), scanned A, original, MIT.

A guide for building enterprise Java applications with Jakarta EE, a set of standard APIs for web services, databases, security, and validation.

In plain words
What is it for?
It supports REST APIs, dependency injection, database persistence, transactions, input validation, and server-managed security for regulated or vendor-portable applications.
Why use it?
It helps teams follow portable Java standards instead of relying on one application-server vendor or Spring-specific conventions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

jakarta-ee-enterprise-platform scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Jakarta EE Enterprise Platform

Use When

  • Delivering Java EE/Jakarta EE compliant applications on Payara, WildFly, OpenLiberty, or similar
  • Regulated industries require standards-based, vendor-portable APIs
  • Team standardizes on jakarta.* namespaces (EE 9+) instead of javax.*

Workflow

  1. Structure as enterprise archive: web (JAX-RS/Servlet), EJB/CDI services, JPA persistence unit.
  2. Use CDI @Inject for wiring; @ApplicationScoped for services; @Transactional on boundaries.
  3. Expose REST with JAX-RS @Path resources; validate with Bean Validation (@NotNull, @Valid).
  4. Configure persistence.xml and datasource via server admin or MicroProfile Config.
  5. Deploy with server-managed security (Jakarta Security) or OIDC via MicroProfile JWT.

Required Checks

  • Packages use jakarta.* imports — no legacy javax.* on EE 10+ projects
  • JPA entities managed in persistence unit; no entity leakage in JAX-RS responses (use DTOs)
  • Transactions demarcated at service layer with clear rollback rules
  • Server-specific deployment descriptors documented (datasources, JNDI, security realms)

Examples And Templates

See examples/ for side-by-side good vs bad patterns agents commonly get wrong. See templates/ for copy-paste starters aligned with this skill.

Decision Framework

  • Prefer Jakarta EE when portability across app servers and standards audit trail matter.
  • Use MicroProfile (Config, Health, JWT, OpenAPI) for cloud-native extensions on EE runtimes.
  • Prefer Spring Boot when ecosystem velocity and Spring AI integration outweigh portability.
  • Map security requirements to Jakarta Security annotations before custom filters.

Common Rationalizations And Rebuttals

  • "Jakarta EE is legacy." -> EE 10+ is actively evolved; major vendors ship modern runtimes.
  • "EJB is always required." -> CDI + JAX-RS + JPA covers many apps; use EJB when spec needs container transactions/messaging.
  • "javax and jakarta are interchangeable." -> Migration breaks compilation; enforce jakarta imports.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
