Consensus review

consensus

Request 2-5 independent AI reviewers for a prompt, collect responses with observed diversity, and obtain an optional synthesized summary to support decision-making.

Instructions

Ask 2-5 independent reviewers and return responses, observed diversity and an optional heuristic synthesis. May consume provider credits. Reuse the project_id and mission_id of the current task (from project_init / memory_checkpoint); when omitted, results go to project "default" and a new random mission that mission_status and memory_checkpoint will not find.

A4.6/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Beyond the annotations, the description discloses that provider credits may be consumed and that omitting project_id/mission_id silently routes results to project 'default' under a new random mission that mission_status and memory_checkpoint will not find. This is exactly the side-effect information an agent needs before invoking the tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences: core function first, cost second, and state-routing consequences third. Every sentence earns its place and there is no repetition of schema detail.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 17-parameter tool with no output schema, the description names the expected returns (responses, observed diversity, optional synthesis) and covers the critical side effects around cost and mission/project routing. It is adequate but not exhaustive; output shape and specific failure modes are left to the schema, which is fully documented.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description adds meaningful cross-parameter context by instructing the agent to reuse the current task's project_id and mission_id and explaining the failure mode when they are omitted, which is not inferable from individual schema fields.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a concrete action, 'Ask 2-5 independent reviewers', and names the deliverables: responses, observed diversity, and an optional heuristic synthesis. This distinguishes consensus from sibling tools like delegate and swarm_run by focusing on independent reviewers and diversity reporting.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives clear operational context: when you want multiple independent reviews with diversity and optional synthesis, and it flags that provider credits may be consumed. It also gives explicit guidance to reuse the current project_id and mission_id and warns about the consequences of omitting them, though it does not explicitly contrast consensus with delegate or swarm_run.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
