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 | $0.00287 | $0.00287 |
| Opus 5.5 | $0.00115 | $0.00115 |
| Sonnet 5.5 | $0.00057 | $0.00057 |
| Haiku 4.5 | $0.00029 | $0.00029 |
Grade A, and why
nestjs-starter interfaces.instructions.md 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 2mo 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
Interface Conventions
Database entity interfaces (src/common/database/interfaces/)
import type { Post } from '@prisma/client';
// Entity is always a direct type alias from Prisma — never re-declared
export type PostEntity = Post;
// CreateInput: all fields required for creation (no id, createdAt, updatedAt, deletedAt)
export interface CreatePostInput {
title: string;
authorId: string;
published?: boolean;
}
// UpdateInput: all fields optional
export interface UpdatePostInput {
title?: string;
published?: boolean;
}
Request interfaces (src/common/request/interfaces/)
// IAuthUser: what JwtAccessGuard puts on request.user
export interface IAuthUser {
userId: string;
role: UserRole;
}
Response interfaces (src/common/response/interfaces/)
- Mirror the DTO shape for use in interceptors/filters.
- Use generics for data payloads (
IApiSuccessResponse<T>).
Rules
- Never use
any— useunknownwith type narrowing or a proper interface. - No business logic in interface files — types and interfaces only.
- Import Prisma types with
import type { X } from '@prisma/client'— alwaystypeimport.
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.
