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 | $0.00048 | $0.01964 |
| Opus 5 | $0.00024 | $0.00982 |
| Sonnet 5 | $0.00010 | $0.00393 |
| Haiku 4.5 | $0.00005 | $0.00196 |
Grade F, and why
github-auth scanned grade F with 4 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.
Enumerates the file system for secretshighData exfiltration
Searching home directories for .env, .ssh, .aws or credential files is reconnaissance for credential theft.
ls -la ~/.ssh/id_*.pub 2>/dev/null || echo "No SSH keys found" Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
3. If `gh` is not installed → use "git-only" method below (no sudo needed) Reaches for credential fileshighPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.
ssh-keygen -t ed25519 -C "[email protected]" -f ~/.ssh/id_ed25519 -N "" Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
When `gh` is not available, you can still access the full GitHub API using `curl` with a personal access token. This is how the other GitHub skills implement their fallbacks. 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 ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

github-auth is a skill published in the GitHub repository Heldinhow/hermes-agent-skills (2 stars, last pushed 4mo ago), with no licence file. It adds 48 tokens to every session and 1,964 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it F with 4 findings (enumerates the file system for secrets, asks for root, reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
