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

With no annotations provided, the description carries the full burden and does meaningful work: it discloses the caller-ownership requirement, states that existence is not publicly enumerable, and notes the audit history is bounded. It does not disclose output shape details, but the core behavioral traits are covered.

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 a single dense sentence that front-loads the primary purpose. The 'TASK-ID-008' parenthetical adds little value, but there is no redundant restatement of the tool name or schema.

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?

The tool is simple (one parameter, no output schema), and the description covers the key context an agent needs: ownership constraints, privacy properties, audit-history scope, and the distinction from the public dossier. A complete return-structure description would be nice, but the missing details are unlikely to block correct invocation.

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 schema has zero description coverage for the single 'subject' parameter, and the description only indirectly explains it as 'the named subject' that must belong to the authenticated caller. This adds some meaning but does not define what a subject is or elaborate on valid input beyond the schema pattern.

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 clearly names the resource ('controller associations') and scope ('the account's own view'), and specifies what is returned ('the current row and a bounded audit history'). It also differentiates itself from the public dossier by noting the public view carries 'present/method only.'

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 auth constraint ('must belong to the authenticated caller') and the non-enumerability statement make it clear when this tool is appropriate. It also implicitly contrasts with the public dossier, indicating that for the public present/method summary, a different tool should be used.

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