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 useful behavior beyond that: it flags that some profile questions are editable and which, and that connected accounts carry a 'whether each still works' health status that can be unhealthy. It says nothing about failure modes for an invalid or inaccessible programme id.

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?

One sentence, front-loaded with what the tool returns, no filler and no restatement of the title. The embedded list is dense but each item conveys a distinct part of the payload.

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?

With no output schema, the description must describe the return payload, and it does so thoroughly, including question ids, editability, team-vs-startup framing, and account connection health. The remaining gap is scoping: it never states explicitly that this returns the caller's own profile rather than another member's.

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 coverage is 100% for the single parameter, and the schema already explains 'Id or domain of one of the person's programmes.' The description adds no further meaning about the programme identifier, accepted formats, or scoping behavior, so the schema carries the load here.

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 gives a specific verb+resource ('The person's profile in a programme') and then enumerates its contents: headline, bio, profile-question answers with question ids, team profile, and connected calendar/video accounts. That is far more specific than the bare 'My profile' title. It does not, however, distinguish this from the sibling get_member_profile, so an agent cannot tell from the text alone which of the two to call.

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?

There is no when-to-use guidance, no exclusion, and no named alternative. The description only inventories what is returned. In particular it never clarifies the 'my' versus 'member' boundary against get_member_profile, which is exactly the decision an agent must make between the two.

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