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

readOnlyHint=true already tells the agent this is a safe single-record read, so the description's bar is low. It adds nothing beyond that: no statement about what happens when the id does not exist (error vs empty), no authorization or scoping notes, and no indication of what an 'AI content analysis' actually contains.

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 front-loaded sentence with zero filler. Its brevity borders on under-specification rather than verbosity, but nothing in it is wasted.

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?

There is no output schema, so the description carries the burden of explaining what comes back; it never says what fields or content an 'AI content analysis' result holds. For a tool whose whole value is returning a structured analysis, that is a material gap even though the call mechanics are simple.

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 description coverage is 0%, but there is only one trivially typed string parameter, and 'by id' does confirm the parameter identifies a content-analysis result rather than, say, a call. The description adds no format, sourcing, or error semantics (e.g., where the id comes from), so it does not fully compensate for the coverage gap.

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 names a specific verb ('Get'), a specific resource ('content-analysis result'), and the scope ('one ... by id'), which cleanly separates it from the sibling list_content_analysis and list_call_content_analysis. It stops short of explicitly naming those siblings, so a reader must infer the routing from the singular/plural contrast.

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 'by id' implies the tool is only usable when an analysis id is already known, which hints that enumeration belongs to the list siblings. There is no explicit statement of when to use this versus list_content_analysis or list_call_content_analysis, and no mention of what to do if the id is unknown.

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