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

Annotations already mark it read-only, and the description adds meaningful context beyond that: login requirement, returned content (latest status, mergeable own organizations, server-side blockers), eligibility threshold of at least two qualified organizations the caller leads, and privacy exclusions. This is strong behavioral disclosure for a read-only 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?

Two compact sentences front-load the login requirement and purpose, then add eligibility and exclusion details. Every clause adds useful information without filler.

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?

No output schema exists, but the description sufficiently explains what the caller gets and what is withheld, including server-side blocking reasons and privacy exclusions. Nothing essential is missing for a zero-parameter read tool.

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 has zero parameters, so parameter semantics are not applicable. Baseline 4 is appropriate.

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?

States a specific read operation: read my latest status, mergeable own organizations, and server-side blocking reasons before applying to establish an alliance. It clearly scopes to the caller's own application/eligibility, distinguishing it from submit_alliance_application and organization-alliance status 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?

Explicitly says to read this before applying to establish an alliance, giving a clear usage trigger. It does not name alternative tools or when-not-to-use cases, so it falls short of top-tier routing guidance.

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