tosea_get_permissions_summary

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

The description uses 'Inspect' which implies a read-only, non-destructive operation. Without annotations, this is sufficient to convey that no changes are made. More detail on output format could be given, but the behavioral intent is clear.

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, concise sentence that is front-loaded with the key action and resource, earning its place with no wasted words.

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 tool's simplicity (zero parameters, no output schema), the description adequately covers what it does and when to use it. It could mention the return value format, but for a pre-check tool, the current description is sufficient.

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 input schema has no parameters, and the description does not need to add param info. Baseline 4 applies as the description correctly focuses on the tool's purpose without needing parameter details.

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 verb 'Inspect' and the resource 'current account tier and feature access', making the tool's purpose evident. It distinguishes from siblings by focusing on permissions summary, which is unique among the listed tools.

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 says 'before expensive runs', providing clear context for when to use the tool. It does not explicitly mention when not to use or alternatives, but the single use case is well-defined.

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