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 5.1 | $0.00054 | $0.00502 |
| Opus 5 | $0.00027 | $0.00251 |
| Sonnet 5 | $0.00011 | $0.00100 |
| Haiku 4.5 | $0.00005 | $0.00050 |
Grade A, and why
dns 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 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.
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
DNS lookups with dig
SLICC's built-in dig resolves DNS records over DNS-over-HTTPS (DoH):
dig <name> [type] [@server] [+opts] [--json]
dig <type> <name> [@server] [+opts] [--json]
dig -x <address> [@server] [+opts] [--json]
dig -v | dig --version
The name and supported record type may appear in either order. A lone positional
is always the name and defaults to type A. Supported types are A, AAAA,
MX, TXT, CNAME, NS, SOA, SRV, PTR, and CAA.
Resolver selection
| Resolver | Supported @server values |
|---|---|
| Cloudflare | @1.1.1.1, @1.0.0.1, @cloudflare-dns.com |
@8.8.8.8, @8.8.4.4, @dns.google |
|
| Quad9 | @9.9.9.9, @149.112.112.112, @dns.quad9.net |
Cloudflare is the default. Any other @server falls back to Cloudflare and
prints a note on stderr because arbitrary DNS servers cannot be queried over
the built-in DoH transport.

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.

dns is a skill published in the GitHub repository ai-ecoverse/slicc (30 stars, last pushed yesterday), licensed Apache-2.0. It adds 54 tokens to every session and 502 once invoked, about $0.0003 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 2026-09-05.
