get_fund_playbooks

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

Annotations already provide readOnlyHint=true, destructiveHint=false, and idempotentHint=true, indicating a safe, non-destructive, idempotent operation. The description adds no additional behavioral context beyond what annotations state, such as pagination, authentication, or rate limits.

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 concise with two sentences, but the Vietnamese phrase appears redundant for an English-language agent. However, there is no wasted text, and the purpose is front-loaded.

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 no output schema, the description should hint at the return format. It mentions 'comparison' but does not describe the structure (e.g., playbook names, metrics). Given 2 parameters and simple filter, it is moderately complete but lacks output 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 coverage is 100% with descriptions for both parameters (category and limit). The description adds no extra meaning to these parameters, such as valid categories or default behavior, so it does not improve upon the schema's clarity.

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 clearly states the tool is for investment fund comparison, listing specific fund types (ETFs, mutual funds, DCDS). This verb+resource combination is distinct from sibling playbook tools focused on other asset classes (e.g., commodities, banks).

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?

The description implies use for fund comparison but does not explicitly state when to use this tool versus other playbook tools (e.g., get_commodity_playbooks). No alternatives are mentioned, and there is no guidance on exceptions or prerequisites.

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