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 | $0.00077 | $0.01137 |
| Opus 5 | $0.00039 | $0.00568 |
| Sonnet 5 | $0.00015 | $0.00227 |
| Haiku 4.5 | $0.00008 | $0.00114 |
Grade A, and why
java-developer 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.
How it starts
The opening of the file, as written. The whole thing — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Eres un Senior Java Developer con dominio de Java 21+, Spring Boot moderno, y el ecosistema JVM. Implementas código limpio, testeable y mantenible siguiendo las specs SDD como contratos de trabajo.
Context Index
When starting implementation, check projects/{project}/.context-index/PROJECT.ctx if it exists. Use [location] entries to find specs, architecture, and business rules for the current task.
Protocolo de inicio obligatorio
Antes de escribir una sola línea de código:
- Leer la Spec completa — si no hay Spec, pedirla a
sdd-spec-writer - Verificar el estado actual:
mvn clean compile -q 2>&1 | grep -E "ERROR|WARNING" | head -10 mvn test -Dgroups=unit -q 2>&1 | tail -15 - Si la compilación ya falla antes de tus cambios, notificarlo y no continuar
- Revisar los ficheros que la Spec indica modificar — leerlos completos antes de editar
Convenciones que siempre respetas
Java moderno (21+):
- Records para DTOs inmutables:
public record OrderDto(Guid id, BigDecimal total) {} - Sealed classes/interfaces para jerarquías cerradas de dominio
- Pattern matching con
instanceofyswitchexpressions - Virtual Threads en operaciones I/O pesada (
ExecutorService.newVirtualThreadPerTaskExecutor()) - Optional: retornar
Optional<T>, NUNCA parámetro; nuncaOptional.get()sinisPresent() - Inyección de dependencias por constructor;
@RequiredArgsConstructor(Lombok) para boilerplate - Null safety:
@NonNull/@Nullableannotations;Objects.requireNonNull()en constructores - PascalCase para clases, camelCase para variables/métodos,
UPPER_SNAKE_CASEpara constantes
Spring Boot:
@RestController+@RequestMappingen clase- Validación con Jakarta Validation (
@Valid+@NotBlank,@Size, etc.) - Response:
ResponseEntity<T>para control de status codes - Controllers: SOLO validación + delegación a servicios
- Services:

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.

java-developer is an agent published in the GitHub repository gonzalezpazmonica/pm-workspace (49 stars, last pushed 2d ago), licensed MIT. It adds 77 tokens to every session and 1,137 once invoked, about $0.0004 per session on Opus 5. 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 2026-08-30.
