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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, covering the safety profile. The description adds the return shape (pool id, name, date added, referrer) and the underlying endpoint, which is useful, but says nothing about pagination or empty-result behavior for a candidate with no pools.

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 segments with the returned fields front-loaded and the endpoint appended as a reference. No waste, though the leading fragment lacks a verb and relies on the reader completing the sentence from the title.

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 simple single-parameter read with no output schema, the description compensates by naming the returned fields, which is the main thing missing from structured data. Annotations handle safety; only pagination/empty-state behavior is unaddressed.

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?

There is only one parameter and schema description coverage is 100%, so the schema fully documents candidate_id as a Taleez candidate id. The description only echoes it via the {id} path template and adds no format or constraint detail beyond the schema, so the 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?

Names the resource precisely (talent pools a candidate belongs to) and enumerates the returned fields, so an agent knows exactly what to expect. It does not differentiate from the reverse-direction sibling taleez_list_pool_candidates or mention the underlying GET endpoint's resource direction explicitly.

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?

Usage is implied by the required candidate id and the 'belongs to' phrasing, making it clear this is the candidate→pools direction. There is no explicit when-to-use versus taleez_list_pool_candidates or taleez_add_candidates_to_pool, so the agent must infer the direction from the name.

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