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

Annotations already flag destructiveHint=true and openWorldHint=true; the description adds the crucial concrete consequence — approving shares the user's contact details with the recruiter — which is exactly the kind of context annotations cannot convey. It stops short of saying the decision is final or what happens on decline (no data shared, request left pending?).

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 efficient sentences that lead with the action and then the consequence; nothing is wasted. It is appropriately short for the operation, and the key side effect is front-loaded rather than buried.

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 3-required-param mutation with an output schema absent, the definition covers the action, the data-sharing consequence, and (via schema) where ids come from. Minor gap: it never states whether the decision can be changed afterward or what a decline does, which matters for an idempotentHint=false, destructive 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?

Schema coverage is 100% and the field descriptions already explain cvId source (list_my_takemeup_cvs), interestId source (get_takemeup_get_found), the decision enum, and locale fallback. The description adds nothing about parameters, so baseline 3 applies.

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 verb pair (approve or decline) and a specific resource (a recruiter's contact request tied to one of the user's CVs). It is clearly distinguishable from read-side siblings like get_takemeup_get_found, though it does not name them.

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 implies usage context (a pending recruiter request exists) and the schema's interestId field points to get_takemeup_get_found, but the description itself gives no explicit when-to-use or when-not-to-use guidance or names an alternative.

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