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 | $0.00019 | $0.00233 |
| Opus 5 | $0.00010 | $0.00117 |
| Sonnet 5 | $0.00004 | $0.00047 |
| Haiku 4.5 | $0.00002 | $0.00023 |
Grade A, and why
gemini 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.
What it actually says
Gemini Session
Start a Gemini CLI session with 1M context window for large codebase analysis.
Instructions
- Take the user's prompt from: $ARGUMENTS
- If no argument provided, ask what they want Gemini to help with
- Determine if new or continuation:
- New topic: Use
start_gemini_session - Follow-up: Use
resume_gemini_session
- New topic: Use
- Return immediately with the task_id
- Tell the user:
- "Gemini started (task: <task_id>)"
- "Check results with:
/gemini-result <task_id>"
Do NOT call wait_for_task. Return immediately.
Usage
/gemini Analyze the entire codebase structure/gemini Summarize all API endpoints
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 is a skill published in the GitHub repository agentic-box/owlex (139 stars, last pushed 5mo ago), licensed MIT. It adds 19 tokens to every session and 233 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.
