get_account_status

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

The annotations already declare readOnlyHint=true and destructiveHint=false, and the description does not contradict them. It adds a little behavioral context by specifying what state is reported (login state, account number, active trading guardrails), but it does not elaborate on side effects, freshness, or permission requirements; the openWorldHint annotation covers volatility.

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 only eight words and every word is informative, so it is concise. However, it is a fragment rather than a complete sentence, which slightly weakens clarity even though the tool's name supplies the missing verb.

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 read-only, parameterless tool with a full output schema and safety annotations, the description covers the core subject matter. It omits usage context and side effects, but those are not essential given the structured metadata; the main gap is the lack of an explicit verb or usage context.

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 takes zero parameters, so the schema is complete with 100% coverage and the description has no parameter meanings to add. This matches the baseline of 4 for parameterless tools.

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 enumerates the tool's subject matter ('Login state, securities account number and the active trading guardrails') but lacks a main verb, leaving the name to imply the retrieval action. It is specific enough to differentiate from sibling getters like get_cash or get_portfolio, though the purpose is stated as a noun list rather than an action.

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 alternatives such as get_market_status or get_available_size, no exclusions, and no mention of appropriate trading contexts. The description only lists contents, so an agent gets no help choosing it.

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