A question-answering workflow that sends one difficult question to several independent models, then has another model compare and combine their answers.

Use it for hard research or analysis questions that benefit from parallel answers, web searches, command-line investigation, and a final structured review.

It exposes agreement, contradictions, overlooked details, and gaps that a single answer may miss.

NVIDIA SkillSpector warn 7 Sept 2026

SkillSpector: 2 findings, up to medium

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 →

medium Rogue Agent · line 7
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00304	$0.02995
Opus 5.5	$0.00122	$0.01198
Sonnet 5.5	$0.00061	$0.00599
Haiku 4.5	$0.00030	$0.00299

Security

Grade A, and why

fusion 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 1mo ago.

The scan reads SKILL.md. This mod also ships 8 executable files (scripts/_fusion_lib.sh, scripts/_pty_run.py, scripts/agy_capture.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 181 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Fusion

Fusion turns one prompt into a panel. The question goes to several models at the same time, each answering independently — with web search and bash, and with no knowledge of the others. Then Opus 4.8 (this very session — the orchestrator) reads every answer, extracts the structure of the panel's reasoning (what they agree on, where they conflict, what only one saw, what they all missed), and writes a final answer grounded in that analysis.

The whole mechanism is independence, then synthesis. The diversity that makes a panel beat a single model is harvested, not manufactured: running the same prompt independently yields different reasoning paths, tool calls, and sources. So there are no assigned "lenses" or personas — every panelist gets the user's task verbatim and answers it straight. (See references/panel.md.)

One hard rule: Opus 4.8 always judges and writes the final answer — the pipeline can't be reversed. The panelist models can't call back out to spawn Opus, so Opus is always the driver. The slug reads driver-first for that reason.

Throughout, <skill_dir> is the directory containing this SKILL.md (when installed: ~/.claude/skills/fusion). Write the user's question verbatim to /tmp/fusion_question.txt first — several steps reuse it.

Step 0 — Pick the panel

bash <skill_dir>/scripts/detect_panel.sh

It prints a SLUG= line recommending the richest panel possible on this machine:

Slug	Panel	Requires
`opus4.8-4.8`	the same prompt run twice as 2 independent Opus 4.8 panelists	nothing — always available
`opus4.8-gpt5.5`	Opus 4.8 + GPT-5.5 in parallel	`codex` CLI
`opus4.8-gemini3.1pro`	Opus 4.8 + Gemini 3.1 Pro in parallel	`agy` CLI
`opus4.8-gpt5.5-gemini3.1pro`	Opus 4.8 + GPT-5.5 + Gemini 3.1 Pro in parallel	`codex` + `agy` CLIs

If the user named a slug (or used a pinned /fusion-* command), honor it — but if a required CLI is missing, say so, drop that panelist, and fall back to the next-richest panel rather than failing. Otherwise use the detector's recommendation.

Changes

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.

fusion is a skill published in the GitHub repository duolahypercho/fusion-fable (471 stars, last pushed 3mo ago), licensed MIT. It adds 304 tokens to every session and 2,995 once invoked, about $0.0012 per session on Opus 5.5. 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.
