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 | $0.00024 | $0.00710 |
| Opus 5 | $0.00012 | $0.00355 |
| Sonnet 5 | $0.00005 | $0.00142 |
| Haiku 4.5 | $0.00002 | $0.00071 |
Grade A, and why
github-cli-queries 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.

GitHub CLI Query Skill
Overview
Use the gh CLI tool to efficiently query GitHub pull requests and issues with filtering, date range support, and structured JSON output.
Installation & Setup
# gh CLI is typically pre-installed on most systems
gh --version
# Ensure you're authenticated
gh auth status
# If not authenticated
gh auth login
Basic Patterns
Query Pull Requests by Date Range
# List PRs created in December 2024 with JSON output
gh pr list --repo cli/cli --state all --created "2024-12-01..2024-12-31" --json number,title,createdAt,mergedAt,closedAt,author --limit 500
# Key fields in JSON output:
# - number: PR number
# - title: PR title
# - createdAt: when PR was created (ISO 8601)
# - mergedAt: when PR was merged (null if not merged)
# - closedAt: when PR was closed (null if still open)
# - author: {login: string, name: string}
Query Issues by Date Range
# List issues created in December 2024
gh issue list --repo cli/cli --state all --created "2024-12-01..2024-12-31" --json number,title,createdAt,closedAt,labels --limit 500
# Key fields:
# - number: issue number
# - title: issue title
# - createdAt: when issue was created (ISO 8601)
# - closedAt: when issue was closed (null if still open)
# - labels: array of label objects with name and description
Date Format
- Use ISO 8601 format:
YYYY-MM-DD - Date ranges:
YYYY-MM-DD..YYYY-MM-DD - The range is inclusive on both ends
State Filtering
--state all: Include open, closed, and merged (for PRs)--state open: Only open items--state closed: Only closed items (for issues) or merged/closed (for PRs)
Common Flags
--limit N: Set maximum results (default 30, max typically 500)--json <fields>: Request specific fields as JSON--repo owner/repo: Specify repository
Date Parsing Tips
- Always capture both
createdAtandmergedAt/closedAtto calculate deltas - Handle null values when calculating metrics
- Parse ISO 8601 timestamps in your processing language
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-cli-queries is a skill published in the GitHub repository cxcscmu/SkillLearnBench (80 stars, last pushed 1mo ago), licensed MIT. It adds 24 tokens to every session and 710 once invoked, about $0.0001 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.
