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

Annotations already cover readOnly, idempotent, non-destructive and openWorld, so the safety profile is known. The description adds genuinely useful behavior beyond them: results are filtered to still-free addresses, each entry carries a suggested photo_url to display, and the create step can bundle name+address+photo. It does not say what happens if a suggestion's address gets taken between calls.

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?

Three short sentences, front-loaded with what is returned and followed by the actionable next step. The cross-tool parameter reference is useful but could be attributed to the create tool by name for zero extra 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?

No output schema exists, and the description only partially covers the return shape (names, free addresses, photo_url) without saying whether it is a bare list, how many suggestions, or whether photos are URLs to render. The required company scoping is entirely unexplained, which is the main gap for a one-parameter input.

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 single parameter 'company' is a UUID with 0% schema description coverage and the description never mentions it, so nothing explains what the company scopes or where to obtain the ID. Instead the description discusses 'use_suggested_photo', a parameter belonging to a different tool, which can mislead an agent scanning this schema.

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: suggested female/gender-neutral teammate names whose gosummer.ai address is still free. It is distinguishable from summer_teammates_list (existing teammates) and summer_teammates_create (which consumes these suggestions), though it never names those siblings explicitly.

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 implies the workflow (list suggestions, then create with use_suggested_photo: true) and clarifies that a typed first/last name is also acceptable, which implicitly scopes when this tool is optional. However, it never names summer_teammates_create as the follow-up tool nor states when to prefer this over just typing a name.

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