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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description does add real value with the pagination note for the knowledge section and the disclosure that unconfirmed files are counted but not shown, plus the admin-privacy constraint — though it says nothing about the size or shape of the knowledge list or cursor behavior.

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?

It is one long semicolon-chained sentence: dense and front-loaded with the core identity of the tool, but the run-on structure makes the section inventory harder to scan than a short bulleted or sentence-per-area form would be.

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?

An output schema exists, so return values need not be explained, and the description covers content areas and the privacy boundary adequately for a read-only self-profile tool. What it lacks is any routing guidance versus the many context-retrieval siblings, which is the main thing an agent needs beyond the 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?

Schema description coverage is 0%, so the description must carry parameter meaning, and it largely does not. The word 'paginated' hints at limit/cursor for the knowledge section only, but neither limit (max 50) nor cursor is explained, and the sections enum values are only loosely echoed by the content-area list without stating that selecting sections is what filters the response.

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 inventories exactly what the tool returns (profile fields, work context, confirmed knowledge, connections, tools) and states the privacy scope ('Only ever your own data, even for org admins'), which implicitly separates it from org-wide siblings like get_entity_context. It is clear but never names a sibling alternative by name, so differentiation relies on inference.

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 only implied by the phrase 'for personalising answers' — there is no explicit when-to-use statement and no guidance on when to prefer get_entity_context or get_context_bundle instead. An agent can infer this is the self-profile call, but must reason about it rather than read it.

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