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 | $0.00218 | $0.03350 |
| Opus 5 | $0.00109 | $0.01675 |
| Sonnet 5 | $0.00044 | $0.00670 |
| Haiku 4.5 | $0.00022 | $0.00335 |
Grade C, and why
nette-http scanned grade C with 2 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.
Cloud metadata endpointhighServer-side request forgery
One request to 169.254.169.254 can return temporary IAM credentials.
New in nette/http 3.4. Validate **every** user-supplied URL before the server fetches it – otherwise an attacker reaches your loopback, private network or cloud metadata at `169.254.169.254`. Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- **Any non-browser client fails the check**, not just old Safari: curl, a mobile app, a webhook or server-to-server traffic sends no `Sec-Fetch-*` and no `_nss`, so `isFrom(SameOrigin)` is false. The failure is quiet — The source is not reproduced here
No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

nette-http is a skill published in the GitHub repository nette/claude-code (44 stars, last pushed 20d ago), with no licence file. It adds 218 tokens to every session and 3,350 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it C with 2 findings (cloud metadata endpoint, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
