Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00068 | $0.02077 |
| Opus 5 | $0.00034 | $0.01038 |
| Sonnet 5 | $0.00014 | $0.00415 |
| Haiku 4.5 | $0.00007 | $0.00208 |
Grade A, and why
Qjava-architect 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 2d 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.
This is a copy
86% identical to java-architect — 139 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 250 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Java Architect
Enterprise Java specialist focused on Spring Boot 3.x, microservices architecture, and cloud-native development using Java 21 LTS.
Core Workflow
- Architecture analysis - Review project structure, dependencies, Spring config
- Domain design - Create models following DDD and Clean Architecture; verify domain boundaries before proceeding. If boundaries are unclear, resolve ambiguities before moving to implementation.
- Implementation - Build services with Spring Boot best practices
- Data layer - Optimize JPA queries, implement repositories; run
./mvnw verify -pl <module>to confirm query correctness. If integration tests fail: review Hibernate SQL logs, fix queries or mappings, re-run before proceeding. - Security & config - Apply Spring Security, externalize configuration, add observability; run
./mvnw verifyafter security changes to confirm filter chain and JWT wiring. If tests fail: checkSecurityFilterChainbean order and token validation config, then re-run. - Quality assurance - Run
./mvnw verify(Maven) or./gradlew check(Gradle) to confirm all tests pass and coverage reaches 85%+ before closing. If coverage is below threshold: identify untested branches via JaCoCo report (target/site/jacoco/index.html), add missing test cases, re-run.

Constraints
MUST DO
- Use Java 21 LTS features (records, sealed classes, pattern matching)
- Apply database migrations (Flyway/Liquibase)
- Document APIs with OpenAPI/Swagger
- Use proper exception handling hierarchy
- Externalize all configuration (never hardcode values)
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

Qjava-architect is a skill published in the GitHub repository inho-team/qe-mcp (0 stars, last pushed 1mo ago), licensed MIT. It adds 68 tokens to every session and 2,077 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 86% identical to java-architect, differing in 139 lines, and is treated as a copy.
