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

No annotations are provided, so the description carries the full behavioral burden. It discloses the data domains and the temporal scope ('upcoming'), which is useful, but says nothing about data freshness, historical coverage, or response format. For a read-only lookup this is thin but not misleading.

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?

A single front-loaded sentence with no filler. It reads as a noun phrase rather than a verb-led statement, but every word earns its place.

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 one-parameter lookup with no output schema, the description names the returned data domains (schedules, cliff dates, supply inflation impact), which is enough to set expectations. It could say more about time horizon and coverage, but it is largely complete.

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% and the lone parameter (token_symbol) is already documented with examples in the schema, so the description has no parameter obligations. Baseline 3 applies.

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?

Names a specific resource (VC/team token unlock schedules, cliff dates, circulating supply inflation) with enough detail to distinguish it from the crypto-adjacent siblings like getCryptoDexLiquidity. An agent can tell this returns token-supply unlock data without opening the schema.

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?

Usage is implied by the content ('upcoming' unlock schedules suggests forward-looking analysis), but there is no explicit when-to-use, no mention of alternatives, and no scope constraints. Adequate at best.

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