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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint, covering safety. The description adds the 'Requires User.Read' permission requirement, which is not in the annotations, providing useful behavioral context beyond what structured data provides.

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 three sentences: the main action, usage guidance with examples, and permission requirement. Every sentence earns its place, no fluff, and the most important information is front-loaded.

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 simple self-profile retrieval tool with zero params and no output schema, the description is complete: it states what is returned (name, email, job title, department, office), when to use it, and the required permission. No gaps.

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 has zero parameters, so the description doesn't need to explain parameter meaning. It mentions 'Takes no arguments', which is redundant with the empty schema but harmless. Baseline for 0 params is 4, and no additional info 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 clearly states the tool's function: 'Get the signed-in user's own profile' and lists the specific fields (name, email, job title, department, office). It uses a specific verb + resource and distinguishes itself from sibling tools like people_get and people_search by explicitly focusing on the signed-in user.

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 description provides explicit usage guidance: 'Call this first when a request says "me", "my" or "I"' and gives concrete examples like filtering a calendar or addressing a message. This tells the agent exactly when to use this tool versus alternatives.

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