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

issues-core 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

Issues — core rules

Follow ARCHITECTURE.md and existing code in the same package.

Stack

  • Quarkus REST + Hibernate ORM + PostgreSQL + Flyway.
  • Angular SPA via Quinoa (src/main/webui/).
  • JWT auth (SmallRye JWT); API base path /api.

Endpoints

  • @ApplicationScoped + @Path; suffix *Endpoint.
  • Constructor injection for repositories and services.
  • HTTP body types: Java record, suffix Request / Response — issues-http-contract.mdc.
  • Response mapping: static load() factory on *Response records.
  • Security: @DenyAll on class + @RolesAllowed on methods for protected resources.

Data access

  • Repositories: EntityManager directly; Optional for single results; @Transactional on mutating methods — issues-jpa.mdc.
  • Non-trivial domain logic: @ApplicationScoped *Service (e.g. TicketHistoryService, MailerService).
  • Cross-cutting notifications: CDI events + SSE in notifications.

Frontend

  • Services in src/main/webui/src/app/services/ — HTTP calls to /api.
  • Components by feature folder under components/.
  • Auth: auth.guard.ts, auth.interceptor.ts for Bearer token.

Never

  • System.out.println — use SLF4J.
  • Raw VO/DTO suffix on HTTP types.
  • Hardcode new API paths in multiple Angular files — centralize in services.

When adding a feature

development-process.mdc — feature analysis → architecture design → task break → explicit task approval → TDD. Answering FQ/AQ is not approval. Then ARCHITECTURE.md §12 — domain spec → package → tests → endpoint → Angular service/component → feature catalog.

When fixing a test

Understand failure first; fix production code or test data via Given. Do not weaken assertions.

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.
