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

Annotations already declare readOnlyHint=true and destructiveHint=true — a conflicting pair the description does nothing to resolve, since it implies a purely derived, harmless line. It adds only the data source ('from the brief's own record'); it says nothing about side effects, permissions, or why the call is non-idempotent.

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 sentences, front-loaded with what the line is, followed by where to use it. Dense with em-dashes but no filler; slightly awkward that half the text is placement advice rather than tool behavior.

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, and the description does describe the shape of the returned line, which is helpful. However, it omits what happens if the brief lacks AI-usage records, error behavior for an invalid brief_id, and any clarification of the contradictory annotation profile.

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 100% for both parameters (author, brief_id), so the schema carries parameter meaning. The description adds no format or syntax detail for either parameter beyond what the schema states; 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?

The description conveys that the tool yields a single disclosure line about how a piece was made, drawn from a brief's record, but it never states the action directly (e.g., 'returns/generates') and reads partly as guidance for the agent. The resource is identifiable, yet no sibling differentiation is offered (e.g., versus get_content_brief).

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?

It instructs where to place the output ('at the end of the piece in italics') and why a specific disclosure helps, but gives no conditions for invoking the tool, no prerequisites, and no comparison to alternatives like get_content_brief or get_audit_report.

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