get_folder

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

Annotations already declare readOnlyHint and destructiveHint, so the behavior is partially transparent. The description adds context: accepts ID or partial name (case-insensitive), which is behavioral info not in annotations. No contradictions.

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 three front-loaded sentences. Each sentence serves a purpose: purpose, input, exclusions. No redundant or unnecessary 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?

For a simple retrieval tool with good annotations and full schema coverage, the description is complete. It explains when to use, input options, and exclusions. Could marginally benefit from describing the return value, but not essential.

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 baseline is 3. Description mentions the two params and their alternatives, but does not add significant meaning beyond schema descriptions. The emphasis on 'either ID or partial name' is useful but not a major semantic addition.

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's purpose: viewing details of a specific Cloud Analytics folder. It specifies input options (ID or partial name) and explicitly distinguishes from sibling tools like list_folders and get_report_config, ensuring no ambiguity.

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 usage guidance is provided: use when viewing a specific folder, avoid for listing all folders or viewing reports. Alternatives are named (list_folders, get_report_config), making the decision process clear.

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