get_session_kvp_report_by_domain

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

The annotations already declare readOnlyHint=true, so the description does not need to restate safety. It adds context by specifying the data source (Snowflake) and the returned columns, but does not disclose performance characteristics, rate limits, or the behavior when optional parameters are omitted.

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 concise with two sentences. The first sentence states the core function, and the second lists key output columns. It is front-loaded and efficient, though it could be slightly more structured for readability.

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 that there is no output schema, the description compensates by listing the returned columns. It covers the main purpose and data source. However, it does not explain optional filtering beyond 'key', or how timezone and network_code affect results. Still, it is fairly complete for a read-only report 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 100%, so the parameters are already described in the schema. The description adds minimal extra meaning beyond stating that results are filtered by the given key, which aligns with the key parameter. No additional clarification on format or usage of optional parameters like timezone or network_code.

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 that it provides a session-based KVP report for a domain, using Snowflake data, and lists the output columns. However, it does not explicitly distinguish itself from sibling tools like get_kvp_report_by_domain, which likely serves a similar purpose but without the 'session' qualifier.

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?

No guidance is provided on when to use this tool versus its siblings (e.g., get_kvp_report_by_domain). There is no mention of prerequisites, data freshness, or scenarios where this tool is preferred.

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