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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the safety profile is covered. The description adds useful behavioral context by stating that results are limited to approved content and returned as stable resource URIs with short excerpts.

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 two short sentences with no wasted words, and the core purpose is front-loaded before the return-value note.

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 3-parameter search tool with rich annotations and no output schema, the description covers purpose and return shape adequately. However, it leaves gaps around parameter meaning for 'kind' and 'limit' and does not guide selection against sibling lookup tools.

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 only 33%: only 'query' is documented with a description. The 'kind' enum and 'limit' bounds/defaults exist structurally, but the description does not explain what kind filtering does or how limit affects results, so it does not compensate for the low coverage.

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 gives a specific verb and resource: 'Search approved maxand98 articles and projects.' It also adds return information ('stable resource URIs and short excerpts'), making the operation clear. It does not explicitly distinguish itself from siblings such as get_document, so it falls short of a 5.

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 description states the search corpus is 'approved maxand98 articles and projects,' which implies scope, but it gives no when-to-use guidance, no exclusions, and no references to alternative tools like get_document or get_claim.

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