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

Matches annotations (readOnlyHint=true, idempotentHint=true). The description provides no extra behavioral details (e.g., error cases, response shape), but annotations already cover the key safety aspects, so this is acceptable but not exceptional.

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?

Two short sentences, front-loaded with the primary action. No filler or redundancy; every sentence serves a purpose. Excellent 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?

The tool is simple and annotations cover safety, but the description omits any guidance on how to use the bulk parameters or which parameters to use in what scenario. It also doesn't clarify the relationship to sibling snapshot tools. Given the lack of schema descriptions不可, this is a moderate gap.

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 has 5 parameters with 0% description coverage. The description only mentions bulk-related parameters (project_ids, project_snapshot_ids) but leaves the required parameters (project_id, project_snapshot_id) and account unexplained. Given the low coverage, the description fails to compensate adequately.

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?

Description clearly states the action ('Get Project Snapshot') and what it returns. The bulk support line adds scope. However, the sentence is nearly tautological with the tool name and would benefit from explaining what a snapshot represents or when it's used.

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?

Explicitly mentions bulk support with 'project_ids' and 'project_snapshot_ids', giving a clear usage pattern. Doesn't name alternative tools explicitly but the sibling list shows related snapshot tools, so context is somewhat weak. The instruction to use bulk fields is a good guideline.

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