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

Annotations are absent, so the description carries the full burden, and it delivers: it discloses read-only semantics, that auth is optional, how sessions are established, and the security-relevant fact that no password is stored. With zero parameters and an output schema present, this is strong behavioral disclosure for a status tool.

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?

Three sentences, each earning its place: the purpose statement is front-loaded, the second gives auth context, the third adds a security guarantee. Zero filler or redundancy; tightly packed and readable.

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 zero-parameter status check with an output schema and no annotations, the description is complete: it covers what the tool verifies, the anonymous-vs-authenticated distinction, session creation path, and privacy behavior. Nothing an agent needs to call and interpret it is missing.

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, so the baseline of 4 applies — there is nothing the description needs to disambiguate. It correctly spends no space on parameters, and the 100% schema coverage (empty schema) leaves nothing undocumented.

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?

Opens with a specific verb-resource statement ('Report whether an authenticated Zameen session is loaded') that unambiguously identifies the tool. It is clearly distinguishable from all siblings, none of which deal with session or auth state, so no confusion is possible.

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 explicit when/when-not guidance against a specific sibling, but that is unnecessary since no sibling overlaps. It supplies useful context on when sessions matter (personalized pages) and how one is created, giving the agent a coherent usage frame. Lacks an explicit exclusion statement but the context is clear.

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