agent-x-gemini

agent-x-gemini is an agent for coding agents from gutomec/nirvana-os-engine. It costs 99 tokens per session (1,702 once invoked), scanned A, original, no licence file.

An autonomous worker that runs tasks through the Gemini command-line tool, a text-based program for using Gemini from a terminal. It acts as a fallback when the harness cannot use the main business or squad route.

In plain words
What is it for?
Use it to execute an enriched task brief from start to finish through Gemini CLI, including handing context between sessions.
Why use it?
It removes the need for a person to guide the task step by step and can continue work across separate sessions using checkpoint files.

Token cost

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.

Security

Grade A, and why

agent-x-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 5d 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 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.
