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 | $0.00008 | $0.01288 |
| Opus 5 | $0.00004 | $0.00644 |
| Sonnet 5 | $0.00002 | $0.00258 |
| Haiku 4.5 | $0.00001 | $0.00129 |
Grade B, and why
network-tools scanned grade B 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 9d 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.
Sends data to an external URLmediumData exfiltration
A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.
curl -X POST -d "data=value" http://example.com Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.

network-tools is a skill published in the GitHub repository chaterm/terminal-skills (58 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 8 tokens to every session and 1,288 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
skillci-guardrails
Use this skill whenever you create, edit, or review a Claude Skill — any SKILL.md file, or the eval cases/config next to one. Most SKILL.md files today are written or edited by an agent, not typed by hand, so this closes the loop by having the agent that just wrote the skill also author it defensively and verify it…
example-skill
Writes a single changelog entry summarizing a code change, given a short description of what changed.
clean-skill
A skill with no lint issues, used as a starting point for the lint-on-type test.
skill-with-referenced-issue
Has a clean SKILL.md but an unsafe referenced script.
council
Run one request through several skills in parallel, isolated subagents, then merge their answers or judge the single best one. Use when the user invokes /council (or /council manage), or uses clear multi-skill-comparison language like "try this with a few different skills", "compare how different skills answer this"…
council-lite
Run one request through several approaches or skills one at a time, keeping each pass as independent as possible, then merge the answers or pick the best one. The claude.ai-compatible version of Council. Use when the user says things like "try this a few different ways and compare", "run this through several of my…
