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 | $0.00193 | $0.00193 |
| Opus 5 | $0.00097 | $0.00097 |
| Sonnet 5 | $0.00039 | $0.00039 |
| Haiku 4.5 | $0.00019 | $0.00019 |
Grade A, and why
nestjs-starter controllers.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 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.
What it actually says
Controller Conventions
- Class decorators:
@ApiTags('public.<name>')or@ApiTags('admin.<name>'),@ApiBearerAuth('accessToken'),@Controller({ path: '/<name>', version: '1' }). - Admin controllers add
@AllowedRoles([UserRole.ADMIN])at class level (always an array). - Every method must have
@ApiEndpoint({ summary, serialization, messageKey }). No bare HTTP decorators without it. httpStatus: HttpStatus.CREATEDfor POST; omit for GET/PATCH/DELETE (defaults to 200).- Controllers return the service result directly — no manual response shaping or wrapping.
- Add
@AuthUser() user: IAuthUseronly when the endpoint needs the requesting user's identity. - Public routes that bypass JWT require
@PublicRoute().
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 controllers.instructions.md is an instructions file published in the GitHub repository hmake98/nestjs-starter (61 stars, last pushed 3mo ago), licensed MIT. It adds 193 tokens to every session, about $0.0010 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.
