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

Annotations already declare readOnly, openWorld, and non-destructive, so the safety profile is covered. The description adds 'bounded', 'verified', and 'from selected relays', which hints at result constraints and relay behavior, but doesn't explain verification meaning or relay semantics.

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?

One tight sentence, fully front-loaded with the key action and constraints. No filler.

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?

A read-only query with annotations and no output schema needs the description to clarify the query semantics and parameters. It covers scope but leaves five undocumented parameters unexplained, which is a notable gap for a filtering tool.

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 0%, so the description must carry parameter meaning, but it only implies a bounded/selected-relay query. None of the five parameters (kinds, limit, since, relays, authors) are explained, leaving the agent to infer semantics from schema structure alone.

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?

Specific verb+resource: 'Read a bounded set of verified public profile or note events from selected relays.' Clearly distinguishes from siblings like publish_event and prepare_event, which involve writing/constructing rather than reading.

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 when-to-use guidance or alternatives named. It doesn't explain when to prefer querying versus using a prepared event, nor the use case for the bounded/verified constraints.

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