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

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, so the safety profile is covered and nothing in the description contradicts it. The description adds authorization framing but omits the tool's defining behavior: that it blocks/polls up to a timeout and what it returns or does when the timeout expires with no code.

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 core action and resource, with no filler or repetition. Slightly more precise wording (e.g. noting it waits) could have replaced the vague closing clause without adding length.

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?

With no output schema, the description should say what comes back (the code string) and what happens on timeout, since the name and timeout_seconds parameter make blocking behavior central. It covers the input side adequately via a fully documented schema but leaves the return and failure semantics unstated.

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 coverage is 100% and all three parameters carry descriptions, including the token's origin in gecici_create_inbox and the timeout bounds. The description adds no meaning beyond the schema, so the baseline of 3 applies rather than a higher score.

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 states a concrete verb and resource: read a verification code from a temporary inbox, scoped by the supplied token. That implicitly separates it from gecici_wait_for_magic_link (links vs codes) and from gecici_get_inbox_messages, though no sibling is named. The main shortfall is that the name promises 'wait' but the description says only 'Read', leaving the polling nature to the schema.

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 phrase 'Use for authorized testing' gives a usage context, and 'inbox owned with the supplied token' implies the token must come from gecici_create_inbox. However, there is no explicit when-to-use versus gecici_wait_for_magic_link or gecici_get_inbox_messages, and no statement of what to do if no code arrives.

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