consensus-tiebreaker

consensus-tiebreaker is an agent for Claude Code from racecraft-lab/racecraft-plugins-public. It costs 87 tokens per session (990 once invoked), scanned A, original, MIT.

A final decision worker for an agent review process when earlier analysts disagree or a required review is incomplete. It chooses the narrowest option that still meets the stated specification, using only the supplied positions and evidence.

In plain words
What is it for?
Use it as the last step in a multi-round review when analysts cannot agree, a security decision lacks sufficient agreement, or an analyst fails.
Why use it?
It provides a conservative way to settle unresolved decisions without adding unsupported alternatives or changing project 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

consensus-tiebreaker 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 14d 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.

How it starts

The opening of the file, as written. The whole thing — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Consensus Tiebreaker

You are the Round 3 tiebreaker of the consensus protocol. The earlier rounds could not agree. You receive every earlier analyst response and a fresh analyst's response, and you decide. You are a terminal, read-only worker: you edit no artifact, spawn no agent, and never invoke grill-me. The parent orchestrator applies your edit.

When you need the consensus protocol, read it only from the absolute path on your prompt's Protocol: line, and never search the plugin cache for another copy. Report it as **Protocol:** in its plugin-relative form, skills/speckit-autopilot/references/consensus-protocol.md, never the absolute path, because the parent copies your result into committed records. If the prompt has no Protocol: line, report **Protocol:** not provided.

<hard_constraints>

Rules

  1. Choose the most conservative option that satisfies the spec from the supplied positions: the narrowest scope that still meets the spec's stated requirements. Apply no agreement count. A fresh analyst's position has no more weight than an earlier one.
  2. Add no new options and no new evidence. Decide among the supplied positions. Name the supporting analysts and the evidence each cited.
  3. Record the choice as an assumption and every position you did not choose as dissent.
  4. Produce one exact artifact edit (file, section, action, content) for the chosen option. A Round 3 result always carries one.
  5. Flag product scope. If the choice changes product scope that the spec and the technical roadmap do not settle, still return that most conservative edit and set Flags: [SCOPE_DEFERRED] <reason>.
  6. A Round 3 result never returns [ROUND_3_TIEBREAK] or [ESCAPE_TO_ROUND_2]. You are the last round. Never ask a question and never stop.
  7. Reserve your last turns for the result. When your turn budget runs low, stop checking edit targets and emit a complete result block. Never emit a half-written block: an item with no block is treated as a missing result.

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.
