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

Annotations already cover safety (readOnly, idempotent, non-destructive, closed-world), so the remaining burden is small. The description does add the meaningful qualifier "connected" — i.e., the authenticated caller rather than an arbitrary user — but discloses nothing about caching, auth requirements, or failure modes.

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?

A single compact sentence with no filler, and the key qualifier ("connected") is front-loaded. It is a noun phrase rather than a verb-led statement, which slightly weakens the framing but costs nothing in length.

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 zero-parameter, read-only tool with a full output schema, the return fields need not be re-explained and annotations carry the safety profile. The definition is essentially complete, with the only real gap being the absence of routing guidance versus sibling identity/profile tools.

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 zero parameters, so per the rubric the baseline is 4. There is nothing parameter-wise for the description to clarify or omit.

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 names the specific resource (the connected Applystead member) and enumerates the returned fields (id, name, email, plan), so an agent can tell what it obtains. It lacks a verb and does not differentiate itself from close siblings such as get_profile, get_account, or get_membership.

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?

No when-to-use guidance is given, and no alternative is named or excluded despite several plausible siblings (get_profile, get_account, get_membership) that could also return identity data. The agent must infer that this is the cheapest identity check.

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