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

With no annotations, the description must carry the behavioral burden. It usefully discloses that the tool is FREE and that it is a read operation, but it omits permissions, rate limits, error behavior, and whether/how alerts are paginated or formatted.

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 front-loaded and free of filler, with 'FREE' first and the core purpose immediately after. It is appropriately terse, though that terseness contributes to the missing parameter and behavioral detail handled in other dimensions.

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 tool with no annotations, no output schema, and 0% schema description coverage, the description is too sparse. It leaves the 'since' parameter unexplained and provides no detail about what alerts contain or how the watch identifier should be supplied.

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 0%, so the description must explain both parameters. It only hints that 'watch' refers to a watch from memecoin_watch, without specifying identifier format, and it never mentions the 'since' parameter at all.

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 states a specific verb and resource: reading alerts associated with a memecoin watch. The parenthetical '(from memecoin_watch)' partially differentiates it from the sibling that likely creates or manages the watch, though it does not contrast with the other memecoin analysis tools.

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 phrase '(from memecoin_watch)' implies this tool is used after a watch exists, but there is no explicit guidance on when to use this versus related tools such as memecoin_watch or memecoin_exit_check. Usage is therefore implied rather than clearly prescribed.

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