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.

[](https://agentmods.dev/skills/jinyimeng01/net-code-audit-skill-master/http-host-header-attacks)What it costs to keep this loaded
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 | $0.00000 | $0.02961 |
| Opus 5 | $0.00000 | $0.01481 |
| Sonnet 5 | $0.00000 | $0.00592 |
| Haiku 4.5 | $0.00000 | $0.00296 |
Grade B, and why
http-host-header-attacks scanned grade B with 1 finding 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 3d 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.
Cloud metadata endpointmediumServer-side request forgery
One request to 169.254.169.254 can return temporary IAM credentials.
│ └── Host: 169.254.169.254 → cloud metadata? Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

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.

http-host-header-attacks is a skill published in the GitHub repository jinyimeng01/net-code-audit-skill-master (5 stars, last pushed 4mo ago), licensed MulanPSL-2.0. It costs nothing until one of its globs matches a file; then it loads 2,961 tokens. A static security scan graded it B with 1 finding (cloud metadata endpoint). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
