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.

SkillSpector: 3 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Excessive Agency · line 34 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
- medium Excessive Agency · line 39 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

What it costs to keep this loaded
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 | $0.00035 | $0.00620 |
| Opus 5 | $0.00017 | $0.00310 |
| Sonnet 5 | $0.00007 | $0.00124 |
| Haiku 4.5 | $0.00003 | $0.00062 |
Grade A, and why
gemini-cli 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 11d 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.

Gemini CLI
Interact w/ Google's Gemini CLI locally. Run queries, get responses, compare outputs.
Prerequisites
Gemini CLI must be installed & configured:
- Install: https://github.com/google-gemini/gemini-cli
- Auth: Run
gemini& sign in w/ Google account - Verify:
gemini --version
When to Use
- User asks to "run/ask/use gemini"
- Compare Claude vs Gemini responses
- Get second AI opinion
- Delegate task to Gemini
Usage
IMPORTANT: Use -p flag for non-interactive (headless) one-shot queries. Without -p, gemini opens interactive mode which hangs in automation.
# One-shot query (MUST use -p for non-interactive)
gemini -p "Your prompt"
# Specific model
gemini -p "prompt" -m gemini-3-pro
# JSON output
gemini -p "prompt" -o json
# Auto-approve tool use (-y is deprecated)
gemini --approval-mode=yolo -p "prompt"
# File analysis
cat file.txt | gemini -p "Analyze this"
Models
| Alias | Use case |
|---|---|
auto |
DEFAULT — routes per prompt (simple → Flash, complex → 3 Pro) |
pro |
Force Gemini 3 Pro (best all-round) |
flash / flash-lite |
Fast, lightweight tasks (3.5 Flash GA rolling out as auto default) |
Omit -m to use auto routing. Aliases beat pinned model ids — they track
upstream model swaps. Pin a full id (e.g. gemini-3-pro) only when the user
names one.
CLI Options
| Flag | Desc |
|---|---|
-p |
Required for headless. Non-interactive prompt |
-m |
Model selection |
-o |
Output: text/json/stream-json |
--approval-mode=yolo |
Auto-approve all actions (-y is deprecated) |
-d |
Debug mode |
-s |
Sandbox mode |
-r |
Resume session |
-i |
Execute prompt then continue interactive |
Comparison Workflow
- Provide Claude's response first
- Run same query via
gemini -p "prompt" - Present both for comparison
Best Practices
- Always use
-pfor automation/one-shot queries - Quote prompts w/ double quotes
- Use
-o jsonfor parsing - Pipe files for context
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.
- 11d ago First seen · 83 lines · 35 tokens per session scan A a7bf14000419
gemini-cli is a skill published in the GitHub repository georgekhananaev/claude-skills-vault (28 stars, last pushed 1mo ago), licensed MIT. It adds 35 tokens to every session and 620 once invoked, about $0.0002 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.
