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

With no annotations, the description carries the full burden and does well: it discloses the HTTP verb (GET, i.e. read-only), the deterministic id ordering, the pagination model, and the returned fields. It omits auth/permission requirements and rate limits, so it is strong but not exhaustive.

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?

Two sentences, front-loaded with the resource and return shape, then the pagination contract. Every clause carries information the schema does not; nothing is wasted.

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?

An output schema exists, so return values need not be spelled out, and pagination, ordering, and bounds are all covered for a simple two-parameter read tool. Only permission/auth expectations are left unaddressed.

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% and neither parameter has a description in the schema, yet the description supplies the critical semantics: limit's valid range (1–1024, beyond the schema's bare default of 32) and the exact cursor convention (last id from the previous page). This fully compensates for the documentation gap.

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 specific verb and resource ('the grid's nodes') and even names the payload fields (id, key, emb) and ordering (id order). It is clearly distinguishable in substance from get_node, but it never explicitly contrasts itself with the single-node sibling, which keeps it 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?

Gives concrete operational guidance: limit is bounded to 1–1024 and the next page is obtained by passing the last id as cursor. It does not state when to prefer this over get_node or list_edges, so it is clear context without explicit alternatives.

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