consensus

A command that asks several experts for views on a question and then uses one final reviewer, called an arbiter, to combine them into a single verdict.

In plain words
What is it for?
Sending a full question and its context for multi-agent deliberation, then using the synthesized result to inform your own decision.
Why use it?
It reduces the risk of relying on one opinion when a question benefits from independent consideration.

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.

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

consensus 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 yesterday.

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

Call the deliberation MCP server's consensus tool to fan out, then run one arbiter pass that synthesizes a single verdict.

Pass the full question and any needed context as the prompt - the expert does not share this session:

$ARGUMENTS

Read the tool result and apply your own judgment; do not relay raw output verbatim.

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.
