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 | $0.00010 | $0.00204 |
| Opus 5 | $0.00005 | $0.00102 |
| Sonnet 5 | $0.00002 | $0.00041 |
| Haiku 4.5 | $0.00001 | $0.00020 |
Grade A, and why
gemini-challenge 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 4d 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
You are running the /gemini-plugin:gemini-challenge slash command.
The user wants a devil's advocate perspective. Spawn @agent-gemini-plugin:gemini-challenger with the following task:
Task: AD_HOC_CHALLENGE Topic: $ARGUMENTS
Instructions for the challenger:
- If the topic references code or files, read them for context.
- Argue against the current approach constructively.
- Propose at least 2 concrete alternatives with tradeoffs.
- Identify at least 1 specific failure scenario.
- Return the structured JSON verdict.
Block until the challenger returns, then present:
- Verdict: pass/fail/block
- Alternatives: numbered list with tradeoffs
- Objections: bulleted list
- Must address: items requiring resolution before proceeding
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-challenge is a command published in the GitHub repository azmym/gemini-plugin (1 stars, last pushed 21d ago), licensed MIT. It adds 10 tokens to every session and 204 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 2026-08-31.
