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 | $0.00000 | $0.00236 |
| Opus 5 | $0.00000 | $0.00118 |
| Sonnet 5 | $0.00000 | $0.00047 |
| Haiku 4.5 | $0.00000 | $0.00024 |
Grade B, and why
gemini-cli 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 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -o GEMINI.md \ What it actually says
Setup: Gemini CLI
Via GEMINI.md (recommended)
Gemini CLI automatically loads GEMINI.md from the project root (and parent directories).
curl -o GEMINI.md \
https://raw.githubusercontent.com/MuhiminOsim/code-refactoring-skill/main/PROMPT.md
Via --system-instruction flag
gemini --system-instruction "$(cat PROMPT.md)" "refactor src/orders.ts"
Or set once as an alias:
alias gemini-refactor='gemini --system-instruction "$(cat ~/.refactor-skill/PROMPT.md)"'
gemini-refactor "extract the discount logic from processOrder"
Via settings.json
Add to ~/.gemini/settings.json:
{
"systemInstruction": "<paste PROMPT.md contents here>"
}
Usage
# Interactive session
gemini
> Refactor processOrder in src/orders.ts — it's 200 lines
> Extract the validation logic into a separate function
> Replace this callback pyramid with async/await
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.

gemini-cli is an agent published in the GitHub repository MuhiminOsim/code-refactoring-skill (5 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 236 tokens. A static security scan graded it B with 2 findings (reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
