users_visible_apps_replace_to_many_relationship

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

No annotations are provided, so the description carries the full behavioral burden. It implies mutation via PATCH but does not disclose that this is a full-set replacement (and therefore removes any currently-linked apps not in the payload), nor any permission, rate-limit, or reversibility information. The only added value is a pointer to the request schema component.

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 text is short and front-loads the endpoint, which is good. But the path is repeated verbatim inside parentheses, wasting the only space available, and the sentence never resolves into a plain-language action.

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 mutation relationship tool with no annotations and no output schema, the description should at minimum explain replace semantics and consequences. Instead it defers almost everything to an external OpenAPI component, leaving the agent without enough context to invoke it correctly and safely.

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 description coverage is 100%, so the id and body parameters are already documented in the input schema. The description's reference to components.schemas.UserVisibleAppsLinkagesRequest duplicates the body field's own description rather than adding format or example detail. Baseline 3 applies.

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 pairs the HTTP verb PATCH with the resource path /v1/users/{id}/relationships/visibleApps, so an agent can infer it modifies a user's visible-apps linkage. However, it never states in words that this REPLACES the entire set, leaving the crucial distinction from siblings users_visible_apps_create_to_many_relationship and users_visible_apps_delete_to_many_relationship to be guessed from the tool name. It is essentially a raw endpoint echo rather than a purpose statement.

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 guidance on when to use this versus the create/delete/get variants of the same relationship. The agent gets no conditions, no prerequisites, and no alternatives, even though four near-identical siblings exist.

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