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 | $0.00251 | $0.00251 |
| Opus 5 | $0.00125 | $0.00125 |
| Sonnet 5 | $0.00050 | $0.00050 |
| Haiku 4.5 | $0.00025 | $0.00025 |
Grade A, and why
nestjs-starter dtos.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 5d 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
DTO Conventions
Response DTOs
- Class implements the entity interface (or
Omit<Entity, 'sensitiveField'>). - Every included field:
@Expose()+@ApiProperty({ example: faker.* }). - Sensitive fields (e.g.
passwordHash,deletedAt):@ApiHideProperty()+@Exclude(). - Named variants extend the base:
export class PostGetResponseDto extends PostResponseDto {}. ResponseInterceptorcallsplainToInstancewithexcludeExtraneousValues: true— fields without@Expose()are stripped.
Request / Input DTOs
- Every field: class-validator decorator(s) first, then
@ApiProperty({ example: ... }). - Update DTOs: all fields
@IsOptional()before their type validators. - Enum fields:
@IsEnum(EnumClass)+@ApiProperty({ enum: EnumClass }). ValidationPipeis global withwhitelist: true, forbidNonWhitelisted: true— extra body fields cause 400.- Never use
@Expose()on input DTOs.
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.

nestjs-starter dtos.instructions.md is an instructions file published in the GitHub repository hmake98/nestjs-starter (61 stars, last pushed 3mo ago), licensed MIT. It adds 251 tokens to every session, about $0.0013 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.
