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

Annotations already cover the safety profile (readOnlyHint true, openWorldHint false), and the description adds genuine context beyond them: fixed ordering, a 50-per-page pagination contract, and the shape of each record. It does not mention rate limits, total result counts, or what happens when the page range is exceeded.

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 that packs ordering, page size, returned fields, the optional filter, and the data source with no filler. The colon-delimited structure keeps the record contents scannable.

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 simple two-optional-parameter read tool with no output schema, the description usefully enumerates the returned fields, compensating for the absent output schema. Minor gaps remain around total counts and pagination end behavior.

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%, so both `days` and `page` are already fully documented with bounds and examples; the description merely restates the optional day window and the page size. Baseline 3 applies because the schema carries the semantic load and the description adds no syntax or edge-case guidance.

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 names a specific resource (upcoming token generation events) and adds the ordering ('soonest first'), page size ('50 per page'), and the fields returned ('date and the project with its categories, website and a short description'). An agent can tell this is a listing tool for future TGEs. It stops short of explicitly contrasting itself with the nearby token_unlocks or upcoming_projects siblings, which keeps it out of the top band.

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 only implied: use it to browse upcoming TGEs, optionally narrowed by a `days` window. There is no explicit statement of when to prefer this over token_unlocks or upcoming_projects, and no exclusions or prerequisites are given.

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