get_margin_attributes

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds useful context by naming the returned attributes, but says nothing about permissions, rate limits, or formatting of the margin values. With annotations carrying the safety burden, this is a modest but real addition.

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 compact and front-loads the purpose before the args list. The single-sentence summary plus a brief Args block contains no filler, though the Args boilerplate is slightly redundant for a one-parameter tool.

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?

There is no output schema, but the description compensates by enumerating the key returned fields, and annotations cover the read-only/open-world nature. For a 1-parameter read tool this is nearly complete, missing only minor operational details.

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?

Schema description coverage is 0%, so the description must compensate, and it does partially: it identifies the single parameter as an Account ID and points to get_accounts as its source. That is adequate for a 1-parameter tool but adds no format or validation detail.

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?

Names a specific verb ('Get') and a precise resource ('margin trading attributes for an account'), then enumerates the returned data (liquid portfolio value, starting/minimal margin, funds sufficiency). This is distinguishable from generic siblings like get_portfolio or get_positions by its margin-specific scope, though it never explicitly contrasts with them.

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?

Usage is implied by the narrow resource ('margin trading attributes'), and it helpfully tells the agent where account_id comes from ('get from get_accounts'). However it gives no explicit when-to-use or when-to-prefer-alternatives guidance relative to portfolio/position tools.

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