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

Annotations already declare readOnly/idempotent/non-destructive, so safety is covered. The description adds real value by describing the returned row shape, the ~200-char description preview, and the hasDescription flag semantics ('false = stride.get_defect would show nothing more'). It says nothing about pagination defaults or total counts, which for a list tool is a remaining gap.

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?

Three dense sentences with the purpose front-loaded, filters in the middle, and the return-shape/routing caveat last. Nothing is repeated from the title or schema, and each sentence adds new information.

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 8 parameters, 13% schema coverage and no output schema, the description steps in to describe return fields and the compact-vs-full tradeoff, which is exactly what's missing structurally. Pagination behavior and result ordering are the only unaddressed points for a paged list tool.

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 only 13%, so the description must carry meaning, and it does for most filters: storyId accepts a ticket key like "ORB-526" or a UUID, search is a title substring, and status/severity/assigneeId are clarified as filters. Only page and limit are left entirely to the schema's defaults and bounds, which is a minor omission.

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 defects in a Stride project') and immediately distinguishes it from the sibling stride.get_defect by scope (compact list vs full detail). An agent can pick between the two 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?

Names the alternative tool explicitly and the condition that selects it ('use stride.get_defect for full detail'), plus enumerates the filter dimensions the listing supports. The routing decision is fully specified rather than inferred.

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