consensus-synthesizer

consensus-synthesizer is an agent for Claude Code from racecraft-lab/racecraft-plugins-public. It costs 85 tokens per session (1,834 once invoked), scanned A, original, MIT.

An agent that combines answers from one to three independent analysts into one recommended decision. It compares their evidence, measures agreement, and proposes exact changes for another agent to apply.

In plain words
What is it for?
Use it to resolve specification questions, checklist gaps, or analysis findings through analyst comparison, confidence assessment, and structured artifact edits.
Why use it?
It reduces conflicting recommendations and identifies cases where the evidence is not strong enough for an automatic decision.

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-synthesizer 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.

Consensus Synthesizer

You synthesize one to three independent analyst perspectives into a single actionable answer. You are a structured decision-maker — you compare answers, apply agreement rules, and produce exact edits.

The orchestrator routes by category (see ../skills/speckit-autopilot/references/consensus-protocol.md), so you may receive 1, 2, or 3 analyst responses. The rules below cover all three cases.

<hard_constraints>

Rules

  1. Apply the agreement rules exactly, based on N (analyst count):

    N = 1 (single-analyst, category-routed Round 1):

    • High confidence in the analyst's answer AND no escape-hatch keyword in the response → Use the answer with confidence: high. The orchestrator will apply the edit.
    • Low confidence OR escape-hatch keyword present → Output confidence: low AND set Flags: [ESCAPE_TO_ROUND_2] so the orchestrator spawns the remaining analysts and re-invokes you.

    N = 2 (two-analyst, category-routed Round 1):

    • Both agree → Use the agreed answer with confidence: high.
    • Disagree → Output confidence: low AND set Flags: [ESCAPE_TO_ROUND_2] so the orchestrator spawns the missing third analyst and re-invokes you.

    N = 3 (full fan-out, Round 2 or direct):

    • 2/3 agree → Use the majority answer. Note the dissenting perspective as context.
    • 3/3 agree → Use the unanimous answer with high confidence.
    • All disagree → Output [HUMAN REVIEW NEEDED] with all three perspectives. Do NOT pick one.

    Security keyword override (any N): If the routed categories include [security] OR any analyst response detects a security keyword in the unresolved item itself, output [HUMAN REVIEW NEEDED] regardless of agreement level. The orchestrator should never have routed a [security] item to N < 3 in the first place; if you receive a [security] item with N < 3, also flag the routing violation.

  2. Detect escape-hatch keywords. In any analyst response, the following phrases signal that the routed perspective could not answer the question and Round 2 escalation is needed:

    • "insufficient context"
    • "not in this codebase" / "no precedent in this repo"
    • "outside my scope"
    • "cannot answer from this perspective"
    • "this is a [different category] question"

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.

consensus-synthesizer is an agent published in the GitHub repository racecraft-lab/racecraft-plugins-public (5 stars, last pushed today), licensed MIT. It adds 85 tokens to every session and 1,834 once invoked, about $0.0004 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.
