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

Annotations already declare this is a safe, read-only, idempotent, non-destructive operation. The description adds useful behavioral context beyond annotations: status meanings, failureCode behavior, draftAllowance reporting, and Revenue Writer plan gating. It does not mention pagination or rate limits, but the output schema likely covers return structure.

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?

The description is front-loaded with the resource scope and ordering, then efficiently defines statuses and plan eligibility. It is dense but information-rich; every clause adds value, though the long sentence structure could be slightly easier to scan.

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 zero-parameter read-only list tool with an output schema, the description supplies the key context an agent needs: time window, ordering, status meanings, failure behavior, draft allowance, and plan gating. Remaining details such as pagination are reasonably left to the output schema.

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?

The tool takes zero parameters, which is the baseline case for a 4. The description adds no parameter semantics because there are none, and schema coverage is 100%, so no compensation is needed.

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 states a specific resource (article briefs), the window (last 14 days plus older briefs with drafts), ordering (newest first), and status semantics. It is clear what the tool returns, though it does not explicitly distinguish itself from siblings such as get_article_brief or generate_article_briefs.

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 scoping rule (recent briefs plus older drafted ones) and plan availability, but there is no explicit when-to-use guidance or comparison to alternatives like get_article_brief for a single brief. An agent can infer the context but must decide the sibling choice itself.

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