  2. Added

TDQS

B3.3/5.0
Behavior3/5

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

Annotations already declare this is a non-read-only, non-destructive, non-open-world mutation. The description adds genuinely useful context beyond them: a per-call cost ($0.05) and the API-key requirement. However, it says nothing about reversibility, behavior when the alias does not exist, or which fields are optional, so the disclosure remains partial.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One sentence plus a compact parenthetical, with the core action front-loaded. Every element carries information and there is no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be described. For a 7-parameter mutation tool with low schema coverage, the description covers cost and auth but omits required-parameter semantics and error/edge-case behavior, leaving it only marginally complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is only 29%, so most parameters are undocumented in the schema. The description names alias_kind/source/display, mapping to three properties, but leaves the required person_id and alias and the idempotency parameters unexplained, so it only partially compensates for the coverage gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (Update) and resource (an existing alias), and enumerates the fields that can change (alias_kind/source/display), so the operation is unambiguous. It does not explicitly contrast itself with the sibling add_person_alias or remove_person_alias, but the 'existing alias' phrasing implies the distinction.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no when-to-use guidance, no mention of when to prefer add_person_alias/remove_person_alias, and no prerequisite stated beyond the API key. The agent must infer from the name that this only applies to an alias that already exists.

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