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

Annotations already establish that this is a read-only, closed-world tool. The description adds useful behavioral context beyond the annotations by explaining that it returns social volume and tone, mentions per network against a baseline, spike and trend signals, and discussions naming the symbol. This helps the agent understand the nature of the response, though it does not detail limitations or baseline methodology.

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, front-loaded sentence that moves from the high-level purpose to specific returned metrics. There is no redundant wording, and every phrase contributes to describing what the tool provides.

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?

For a two-parameter read-only tool with complete schema coverage and no output schema, the description provides enough detail about the returned social metrics to support correct invocation. It is not fully complete because it omits guidance on window selection and does not clarify how tone or baseline are computed, but those gaps are relatively minor given the schema richness.

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 100%, so both parameters are fully documented in the schema itself. The description reinforces that the tool operates on one ticker or coin, but it does not add new semantics for the symbol or window parameters beyond what the schema already provides.

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 resource and scope: social volume and tone for one ticker or coin. It also specifies the types of output (mentions per network, baseline comparison, spike, trend, discussions), so an agent can understand what the tool does. It does not explicitly differentiate itself from sibling social tools, but the purpose itself is 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?

There is no explicit guidance on when to use this tool versus alternatives such as social_top_mentions or social_history. The phrase 'for one ticker or coin' implies a single-symbol lookup, but no conditions, exclusions, or alternative recommendations are given.

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