get_my_rating

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered by metadata. The description adds the 'live' freshness trait and authenticated-user scoping, which are useful beyond the annotations. No contradictions, but no deeper behavior (e.g., behavior when no rating exists) is disclosed.

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?

A single sentence with no filler; the key facts (read, authenticated user, live, one title) are front-loaded and directly useful. It earns its 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?

Given the one-parameter surface and rich read-only annotations, the description is nearly sufficient for a simple read-by-ID tool. The gaps are the undocumented title_id format and the absence of explicit handling for 'no rating exists', but these are minor against the tool's simplicity.

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 0%: the schema only gives type and required flag for title_id, and the description does not explain what format/source the ID should have or how to obtain it (e.g., via search_titles). The parameter name gives a moderate clue, but the description does not compensate for the missing schema documentation. This could lead an agent to pass a title name rather than an IMDb title ID.

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?

Uses a specific verb ('Read') and identifies the exact resource: the authenticated user's own rating, scoped to a single title. This distinguishes it from list_my_ratings (plural) and the set/delete mutators, even without naming them. No ambiguity in what the tool does.

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?

Describes clear usage context: reading only the authenticated user's rating, not public ratings or aggregate data. It does not explicitly name alternatives such as list_my_ratings for fetching all of the user's ratings, so the when/not guidance is left partly to inference from sibling names.

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