C2/5.0

Behavior2/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions 'Entropy + bias gate' and 'No TRU8' but does not explain what these mean, what side effects occur, or what the tool returns. The description is too vague to inform an agent about the tool's behavior.

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

Conciseness3/5

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

The description is very short, which is concise, but it lacks structure and front-loaded clarity. Every word is cryptic and does not earn its place by adding useful information. It is under-specified rather than efficiently concise.

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

Completeness1/5

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

Given the tool has 2 parameters, no output schema, and no annotations, the description is severely incomplete. An agent cannot determine what the tool does, what inputs are expected, or what the output will be. The cryptic references to '$1900 tier' and 'TRU8' are unexplained and likely meaningless to the agent.

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

Parameters2/5

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

Schema description coverage is 50%, with only the 'data' parameter described in the schema. The description adds no parameter-level detail, leaving the 'encoding' parameter and the meaning of 'data' ambiguous. The cryptic phrase 'Entropy + bias gate' does not clarify how to use the parameters.

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

Purpose2/5

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

The description 'Entropy + bias gate for $1900 tier. Always available. No TRU8.' is cryptic and does not state a clear verb or resource. It does not explain what the tool actually does, making it difficult for an agent to understand its purpose. The sibling tools (chamber_status, chamber_info, etc.) suggest a domain, but the description fails to differentiate benefit_check from them.

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

Usage Guidelines2/5

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

The description provides no explicit guidance on when to use this tool versus alternatives. Phrases like 'Always available' and 'No TRU8' are vague and do not clarify usage context. There is no mention of when to prefer benefit_check over sibling tools like chamber_hop_gate or chamber_status.

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