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

Annotations already establish this as a read-only, closed-world operation, so the safety burden is low. The description adds useful context beyond that: what fields come back (id, name, tracking protocol, timezone), the sort order, and the downstream workflow via the id. It does not mention pagination behavior, though the schema fields hint at it.

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 short sentences, each earning its place: discovery purpose, return contents/ordering, and the required follow-up workflow. The 'use this first' guidance 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?

With only two optional parameters, a full output schema, and annotations covering safety, the description supplies everything an agent needs: what it returns, how it's ordered, and how its output feeds the rest of the toolset.

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%, and both limit and offset are fully documented in the schema, so the baseline is 3. The description adds no additional meaning about paging limits or offset semantics beyond what the schema already 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?

States a specific verb and resource ('find the analytics properties... of the connected account') and clarifies what a property is ('tracked websites or apps'). It also distinguishes itself from siblings by declaring itself the entry point before d8a_get_property_context.

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?

Explicit sequencing guidance: 'Use this first' and 'Pass the id to every other tool, starting with d8a_get_property_context.' The agent knows exactly when to call this versus the other eleven sibling tools.

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