Blockchain events

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

Annotations already declare this as a safe, open-world read, so the safety profile is covered. The description adds only that data comes from 'Blockchain Lab feeds' and is scoped to upcoming items; it says nothing about result limits, ordering, or freshness, which is minimal added context.

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 short sentence with no waste and the key scope ('upcoming') front-loaded. It is efficient, though arguably too terse to be maximally useful.

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 zero-parameter list tool with no output schema and annotations covering safety, the description is minimally adequate but leaves open what an 'event' is and how many are returned. A short clause defining the event type would close the gap with the hackathon/grant siblings.

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?

The tool takes zero parameters, so per the baseline this dimension starts at 4. There is no parameter detail the description could add, and it correctly avoids inventing filter semantics.

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?

States a recognizable verb+resource (listing blockchain events) and names a source ('Blockchain Lab feeds'), but 'events' is ambiguous among siblings such as list_hackathons and list_grants, and the description does nothing to distinguish this tool from those. An agent can guess the purpose but cannot confidently route between the list_* siblings.

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 statement of when to use this tool versus alternatives like list_hackathons or list_grants, and no conditions, prerequisites, or exclusions are given. Only the implied 'upcoming' framing hints at usage.

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