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

No annotations are supplied, so the description carries the burden; it does convey that this is a read that returns the full record including a third-party (DefiLlama) description field. It does not mention behavior on an unknown/expired id, error semantics, or whether the payload is cached or paginated, leaving meaningful gaps for a no-annotation tool.

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 identifies the resource, its scope, its payload content, and its id provenance with no filler. The inline example earns its space by pinning down the id format.

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?

With one required parameter at full schema coverage and no output schema, the description does the necessary work by sketching the return content ('in full, with DefiLlama's description'). Only failure-mode behavior for a bad id is left unstated, which is a minor omission for this complexity level.

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 already 100% and the schema documents the id parameter, but the description adds real value beyond it by giving a concrete format example ("llama-1546-2026-04-16") and naming the authoritative source of valid ids. That exceeds the baseline of 3 for a fully documented schema.

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 precisely what is returned — a single NEAR ecosystem security incident 'in full, with DefiLlama's description' — and implicitly scopes it against the sibling list_incidents by requiring an id from that list. An agent can distinguish this from list_incidents without opening either 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?

The phrase 'by the id list_incidents prints' establishes a clear prerequisite workflow: call list_incidents first, then fetch a single record here. It stops short of explicit when-not guidance (e.g. don't call for bulk retrieval or with ids from other sources), so it falls short of a 5.

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