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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered structurally. The description adds one non-obvious access constraint: results are scoped to the linked Market Brew account. That is genuinely useful context beyond the annotations, but return shape, potential size and pagination remain unstated.

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 with no padding, which is a point for conciseness. However, the first sentence is essentially a restatement of the tool name ('Use this when the user asks to get...'), so its structural real estate is not earning its place.

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 sibling set this dense with account-scoped getters and no output schema, the definition should describe what the snapshot contains or how it differs from preview_account_management_command and the usage/metric getters. It does neither, leaving an agent unable to decide when this tool is the right choice.

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?

The tool takes zero parameters and the description does not invent any, so the no-params baseline of 4 applies. There is no parameter content for the description to add or omit.

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 restates the tool name and title almost verbatim: 'get the internal account-management snapshot.' It identifies no specific resource, no dimensions of the snapshot, and does nothing to distinguish it from the many sibling get_* tools (e.g., get_usage_metrics, get_launchpad_stats) that also return account-level data.

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 only guidance is a near-exact echo of the user phrasing ('when the user asks to get the internal account-management snapshot'), which is circular and offers no when-to-use vs. when-not-to-use logic. No alternatives are named despite dozens of overlapping get_* siblings, not least preview_account_management_command and get_customer_license.

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