fusion-gemini

fusion-gemini is a command for Claude Code from duolahypercho/fusion-fable. It costs 40 tokens per session (373 once invoked), scanned A, original, MIT.

A command that asks two different AI models to independently analyze the same task, then has one judge compare their answers.

In plain words
What is it for?
Use it for research, analysis, or coding tasks where you want parallel solutions, a comparison, and one merged answer.
Why use it?
It reduces reliance on one analysis by exposing disagreements and combining separate proposals into a final result.

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

fusion-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 12d 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

Invoke the fusion skill on the task below, forcing the opus4.8-gemini3.1pro panel: Opus 4.8 (Agent subagent) and Gemini 3.1 Pro (via agy, pseudo-TTY) answer the SAME prompt IN PARALLEL, each independently with web + bash and neither seeing the other's work → Opus 4.8 judges both answers → Opus writes the final answer grounded in the analysis.

Follow the skill's SKILL.md exactly (preflight → fan out in parallel → judge picking the track that fits the task → grounded final deliverable → save provenance → present). For a research/analysis task present the standard sections (Consensus / Contradictions / Partial coverage / Unique insights / Blind spots / Final answer); for a code/artifact task run both candidates and merge them into one working result with a merge rationale. Use exactly one Opus 4.8 panelist and one Gemini 3.1 Pro panelist — do NOT add a GPT-5.5 panelist or a second Opus run. Pass the task verbatim to both; no "lenses".

If the agy CLI is missing or the Gemini panelist fails/times out, drop it, record a one-line degradation note, and fall back to opus4.8-4.8 (spawn a second independent Opus panelist) so the judge still sees two blind answers — never abort because one CLI failed.

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.
