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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states what the tool does but doesn't describe behavioral traits such as whether it's a read-only operation, potential rate limits, error handling, or what the return format looks like (e.g., list of glyphs, JSON structure). This leaves significant gaps for a tool with no annotation coverage.

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 a single, efficient sentence that directly states the tool's purpose without any redundant or unnecessary information. It is appropriately sized and front-loaded, making it easy for an agent to parse quickly.

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?

Given the lack of annotations, no output schema, and low schema coverage, the description is incomplete. It doesn't explain return values, error cases, or behavioral constraints, which are crucial for an agent to use the tool effectively. This is inadequate for a tool with such minimal structured data.

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 description adds some meaning by clarifying that 'icon_name' refers to 'a specific icon', but with 0% schema description coverage and only one parameter, the baseline is 4. However, it doesn't provide details like valid icon names, format expectations, or examples, so it doesn't fully compensate for the lack of schema documentation, resulting in a score of 3.

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 action ('Get all glyphs') and the resource ('for a specific icon across all available styles'), making the purpose understandable. However, it doesn't explicitly differentiate from sibling tools like 'get_icon_glyph_by_style' (which presumably gets glyphs for a specific style rather than all styles), so it doesn't reach the highest level of sibling differentiation.

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 provides no guidance on when to use this tool versus alternatives like 'get_icon_glyph_by_style' or 'list_icons'. It lacks explicit when/when-not instructions or prerequisites, leaving the agent to infer usage from the tool name and description alone.

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