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

Annotations already declare a safe read (readOnlyHint=true, destructiveHint=false, openWorldHint=false), so the bar is lower, and the description adds material context beyond them: the auth scope required, that the data is public on the member's profile, that returned ids feed subsequent changes, and the sign-in fallback. It also carries a prompt-injection caution about member-written text, which is relevant for a tool returning free-text notes.

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 core sentence is front-loaded and informative, but the phrasing is garbled in places ("With the id each change takes", "Acts for your member") and the sign-in and injection sentences read as appended boilerplate. It is not bloated, but clarity suffers where it matters most.

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 and a zero-parameter schema, the description carries the burden of describing the return shape, and it does so by naming the fields and the id. Auth, visibility, and fallback behavior are all covered, leaving only the sibling disambiguation as a real gap.

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 no parameters, so there is nothing for the description to disambiguate; baseline 4 applies. The description correctly implies no inputs are needed while clarifying what comes back.

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?

States a specific verb and resource ("Read your member's Tools and equipment") and enumerates the returned fields: name, rating, years, category, note, plus the id used by later mutations. It is clear what the tool does, but it never distinguishes itself from the near-identical sibling list_my_listed_tools, leaving an agent to guess which collection each covers.

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?

It gives real preconditions — needs the member's "See your profile" (profile:read) permission and prompts sign-in if the member hasn't connected Automate America — which is genuine usage context. However, there is no explicit guidance on when to call this versus the many sibling list_* profile tools, or versus list_my_listed_tools, so the selection decision is left implied.

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