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

No annotations are provided, so the description must fully disclose behavioral traits. It merely states the purpose without revealing any behavioral details such as sorting, limitations, or data freshness. The agent gains no insight into side effects or performance characteristics.

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?

The description is a single efficient sentence with no wasted words. However, it could be slightly expanded to include usage context without losing conciseness.

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?

Given the presence of an output schema (not shown) and 100% schema coverage, the description is adequate for a simple listing tool. However, it lacks contextual completeness by not helping the agent differentiate from many similar sibling tools.

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% with parameter descriptions like 'Counter ID' and 'Start date YYYY-MM-DD'. The tool description adds no new meaning beyond the schema, so baseline 3 is appropriate.

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 clearly states the tool retrieves sources driving users to website articles. It uses a specific verb ('get') and resource ('sources'), and the context of analytics distinguishes it from sibling tools like 'get_organic_search_performance' or 'get_traffic_sources_types'.

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 for getting article traffic sources, but provides no explicit guidance on when to use this tool versus alternatives like 'get_traffic_sources_types' or 'get_goals_conversion'. No when-not-to-use or alternative names are mentioned.

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