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 | $0.00093 | $0.01921 |
| Opus 5 | $0.00046 | $0.00960 |
| Sonnet 5 | $0.00019 | $0.00384 |
| Haiku 4.5 | $0.00009 | $0.00192 |
Grade A, and why
using-nestjs-hexagonal 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.

Using NestJS Hexagonal
This is a routing skill. When working in a NestJS project that follows hexagonal architecture, check this skill FIRST to find the right tool for the job.
Detection — When Does This Plugin Apply?
This plugin applies when ANY of these are true:
- Project has
@nestjs/coreand@nestjs/cqrsin dependencies - Project structure has
domain/,application/,infrastructure/layers - Files contain
AggregateRoot,@EventsHandler,@CommandHandler,@QueryHandler - User mentions: entity, value object, bounded context, CQRS, hexagonal, DDD, aggregate
- CLAUDE.md references

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.
- 2d ago First seen · 158 lines · 93 tokens per session scan A 6c5ed6210e96
using-nestjs-hexagonal is a skill published in the GitHub repository Softtor/nestjs-hexagonal (5 stars, last pushed 22d ago), licensed MIT. It adds 93 tokens to every session and 1,921 once invoked, about $0.0005 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 2026-08-31.
