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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the read-only nature is covered. The description adds transparency about what the tool returns (id, login, broker, balance, equity, sync state, strategies) and the critical id-vs-login distinction, going beyond annotation-only disclosure.

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?

Three sentences with no wasted words: the first states the action, the second enumerates return fields, and the third delivers essential integration guidance. It is front-loaded, compact, and every sentence earns its place.

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?

With zero parameters and an output schema available, the description fully covers what an agent needs: what accounts are included, what data is returned, and how the returned `id` connects to other tools. No gaps are apparent for the tool's intended read-only listing use case.

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 the baseline is 4 per the rubric. The description appropriately focuses on output semantics and the meaning of the returned `id` field instead, which is more valuable than parameter details in this case.

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 opens with a specific verb and resource: 'List the MT5 trading accounts linked to the configured Senti Quant API key.' It clearly defines the tool's scope and purpose, and the lack of sibling tools removes any differentiation concern.

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 are no explicit alternative tools to compare against, but the description gives practical usage context by explaining that the returned `id` field is the accountId required by every other Senti endpoint. This implicit guidance about when to use the tool and how to use its output earns above-average marks.

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