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 5.1 | $0.00000 | $0.00321 |
| Opus 5.5 | $0.00000 | $0.00128 |
| Sonnet 5.5 | $0.00000 | $0.00064 |
| Haiku 4.5 | $0.00000 | $0.00032 |
Grade A, and why
jabrena-311-spring-boot-slice-testing 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 1mo 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.
What it actually says
Spring Boot slice testing (external cherry-pick)
Source: jabrena/cursor-rules-java rule 311 — adapted for your monorepo.
Prefer slice tests over full context
| Layer | Annotation | Use when |
|---|---|---|
| Web layer | @WebMvcTest(controllers = X.class) |
HTTP contract, status codes, JSON shape |
| JPA slice | @DataJpaTest |
Repository queries (if JPA present) |
| JSON | @JsonTest |
Serializer/deserializer edge cases |
Rules
- Mock only direct collaborators with
@MockitoBean(Spring Boot 3.4+) or@MockBean. - Do not load full
@SpringBootTestfor controller-only changes. - Use
@Importfor security/GlobalExceptionHandlerwhen needed. - Assert HTTP + JSON body; avoid asserting internal service call order unless behavior-critical.
Conflicts
If this file conflicts with java-springboot-standards.mdc or ArchUnit tests, Agentic Loop standards win.
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.

jabrena-311-spring-boot-slice-testing is a cursor rule published in the GitHub repository pallerana/agentic-loop-engineering-kit (4 stars, last pushed 4mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 321 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
