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

With no annotations provided, the description carries the burden of behavioral disclosure. It usefully reveals the compact response fields and filterability, but it does not mention pagination, sorting, default result size, or that this is a non-mutating read operation.

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 well-structured sentence communicates the resource, the compact output shape, and the available filters. There is no wasted wording, and the key information is front-loaded.

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 list tool, the description adequately covers the resource, output shape, and filtering options, which is especially helpful given there is no output schema. It stops short of full completeness by omitting pagination, sorting, and explicit guidance about retrieving full entry details.

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 100%, so the schema already documents all four parameters. The description reinforces that type, status, and tag are filters, but adds no meaning beyond what the schema provides.

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 uses a specific verb ('List') and resource ('knowledge entries of a project'), and clarifies the output is a compact representation with title, status, date, and link count. This distinguishes it from siblings like get_knowledge (single entry detail) and search_knowledge (search).

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 implies usage: call this to list knowledge entries for a project and filter by type, status, or tag. However, it does not explicitly state when to prefer this over search_knowledge or when to use get_knowledge for full detail, so alternatives are not addressed.

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