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

Annotations already declare readOnlyHint=true, so safety is covered structurally. The description usefully adds the exact REST endpoint and notes filtering/sorting behavior, but says nothing about pagination behavior or defaults beyond what the cursor and limit schema entries already document.

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 compact sentences with zero filler, front-loading the capability before the endpoint detail. Every clause earns its place.

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 read-only collection endpoint with all six parameters fully documented in the schema and no output schema, the description is nearly sufficient. A brief note on default page size or ordering would close the last gap.

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 100% and each parameter already carries a description, so the schema does the heavy lifting. The description's mention of filter/owner/sort merely restates those parameters without adding format, interaction, or default 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 specific verb and resource ('List organizations') plus the two filter axes (filter/owner) and sorting, and pins the concrete endpoint GET /api/v2/organizations. It does not explicitly distinguish itself from the sibling search_organizations, but the read/collection framing is unambiguous.

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?

'optionally filtered by filter/owner and sorted' implies the intended context (browse a collection with light filtering), but there is no explicit when-to-use versus search_organizations when the caller has keywords, nor versus get_organization for a single record. Usage is implied rather than stated.

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