issues-http-contract

Rules for HTTP request and response types in the Java API. An API is the interface that lets the Angular app communicate with the backend over HTTP.

In plain words
What is it for?
Use them when creating endpoints, defining request bodies or response data, adding OpenAPI documentation, or writing API tests.
Why use it?
They keep API names and shapes consistent and allow the API specification to generate matching Angular client code.

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.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 331 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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-http-contract 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 yesterday.

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

HTTP contract

Enforced by ArchitectureTest (ArchUnit).

Naming

  • Request — HTTP body or complex input: CreateTicketRequest, MoveTicketRequest.
  • Response — HTTP output: TicketResponse, TicketExpandedResponse.
  • Never use VO, DTO, or Vo prefix/suffix.

Shape

  • All *Request and *Response types MUST be Java record.
  • Endpoint public methods return *Response, List<*Response>, Set<*Response>, Response, or SSE Event.
  • Endpoint body parameters (non-path/query) MUST be *Request records.

OpenAPI

  • Every endpoint class: @Tag(name = "...") at class level, @Operation(operationId = "...") on the HTTP method.
  • Shared *Request/*Response records live at context root (not inside endpoint classes).
  • Test profile exports spec to target/openapi/openapi.yaml for Angular codegen.

Examples

public record CreateTicketRequest(long projectId, String title, String description, Long categoryId) {}

public record TicketResponse(long id, String identifier, String title) {
    public static TicketResponse load(Ticket ticket) { ... }
}

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.

issues-http-contract is a cursor rule published in the GitHub repository vepo/issues (8 stars, last pushed 1mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 331 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.
