get_helpers_not_tool_not_sub

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

Annotations already declare readOnlyHint and idempotentHint true. Description adds 'directive-callable' qualifier, which provides slight behavioral context beyond annotations. However, no additional traits (e.g., scope, side effects) are disclosed.

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?

Single sentence, no wasted words, front-loaded. However, given the simplicity, adding a clarifying phrase about the tool's specific scope would not harm conciseness.

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?

Despite no parameters and annotations, the description is too minimal for a tool with many siblings. The lack of output schema and omission of filtering logic means the agent may not understand what 'helpers' are or how this differs from similar tools. More context is needed.

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?

No parameters exist, and schema coverage is 100%. Baseline is 3 as per scoring guidelines. Description adds no parameter information, which is acceptable given no params.

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?

Description states verb and resource ('Get all directive-callable helpers') but fails to clarify the distinction from siblings like 'get_helpers_are_tool' or 'get_helpers_are_sub'. The name implies a filter, but the description does not mention it, making the purpose only moderately clear.

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?

No guidance on when to use this tool versus alternatives. With many sibling get_helpers_* tools, explicit context about selecting this specific variant is missing, leaving the agent without direction.

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