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 | $0.00051 | $0.01951 |
| Opus 5 | $0.00026 | $0.00975 |
| Sonnet 5 | $0.00010 | $0.00390 |
| Haiku 4.5 | $0.00005 | $0.00195 |
Grade A, and why
github 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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 287 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GitHub Skill
This skill provides GitHub integration using the official gh CLI tool. A Python wrapper script produces markdown-formatted output for read/view operations. Action commands (create, merge, close, comment) should use gh directly.
Prerequisites
Install gh CLI: installation guide
Authentication
# Authenticate with GitHub
gh auth login
# Verify authentication
gh auth status
See GitHub CLI Authentication for details.
Script Usage
The wrapper script (scripts/github.py) formats output as markdown. Use it for read/view operations to get agent-consumable output. Use gh directly for action commands (create, merge, close, comment). See permissions.md for read/write classification of each command.

All commands support --limit N for list commands (default 30).
Commands (Direct gh Usage)
For action commands, use gh directly:
Issues
gh issue list # List issues
gh issue view 123 # View issue details
gh issue create # Create new issue
gh issue comment 123 # Add comment
gh issue close 123 # Close issue
gh issue edit 123 --add-label bug # Edit issue
What ships with it
3 files 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 is a skill published in the GitHub repository odyssey4me/agent-skills (12 stars, last pushed 5d ago), licensed Apache-2.0. It adds 51 tokens to every session and 1,951 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 2026-08-30.
