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

No annotations are provided, so the description must disclose behavioral traits. The description only implies a read operation but does not mention idempotency, rate limits, authentication needs, or return format. It adds minimal value beyond the name.

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 three-word sentence, which is concise but arguably too terse. It repeats the tool name without adding substance. While front-loaded, it does not earn its place by providing additional clarity.

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 parameters and output schema, the description is insufficient for an agent to fully understand what the tool returns (e.g., list of emoji codes, URLs). The tool is simple, but the description omits necessary context about the response structure or scope.

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?

There are no parameters, so schema coverage is vacuously 100%. The baseline for 0 parameters is 4. The description does not add any parameter information, but also does not detract from the schema.

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 'Get emojis' states the action and resource but is vague; it does not specify the scope (e.g., GitHub emojis, custom) and is essentially a tautology of the tool name 'github_emojis_get'. It distinguishes from sibling tools only by omission, as most siblings are unrelated.

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 is provided on when to use this tool versus alternatives. The description lacks any context about typical use cases or exclusions, leaving the agent to infer usage from the name alone.

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