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

Annotations already establish that this is a safe, read-only, idempotent, closed-world operation. The description adds only 'Current trust ceiling value' and does not explain the relationship between trust decay and the ceiling, nor how the value should be interpreted.

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

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

The description is extremely short, but its telegraphic fragment style leaves key information unstated. Brevity here comes at the cost of clarity rather than from efficient communication.

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

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

For a zero-parameter read-only tool with no output schema, the description should explain what value is returned and how it relates to the tool name. Instead it gives only a vague fragment and does not resolve the tension between 'trust_decay' and 'trust ceiling value'.

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

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

The tool has zero parameters, so there is nothing for the description to clarify beyond what the empty schema already communicates. Baseline 4 applies.

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

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

The description is a noun fragment, 'Current trust ceiling value', with no explicit verb and no explanation of what 'trust decay' means. It does not distinguish this tool from siblings such as trust_score, trust_history, or agents_reputation.

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

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

There is no guidance on when to use this tool versus trust_score, trust_history, or other trust-related siblings. The agent is left to infer usage entirely from the name and a fragment.

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