Set an agent's integrations

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

Annotations only say readOnlyHint=false and destructiveHint=false; the description adds genuinely useful behavior beyond them: this is a full replace (not a merge), an empty list removes all integrations, keys must resolve to connections in the same workspace, and the whole request is rejected with 404 if any key is invalid (implying all-or-nothing). It does not state the permission/scope required to mutate an agent's integrations.

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 sentences, front-loaded with the action and its replace semantics, followed by the edge case (empty list) and then the key format rule. No filler or restated title.

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?

An output schema exists, so the description only needs to note that the updated integrations are returned, which it does. For a mutating tool it covers format, scoping, and failure mode well; the remaining gap is required permissions and whether the operation is atomic across all keys.

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 67% and the undocumented body.integration is exactly what the description explains: the `<INTEGRATION>_<connection id>` format with a concrete example and the same-workspace constraint. That is real value the schema alone does not carry, though the body array's replace-vs-append semantics could be tied more explicitly to the parameter.

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 precise verb+resource ('Replace the integration connections an agent can use with the given list') and pins down the replacement semantics rather than a vague 'update'. It is trivially separable from the read-side sibling list_agent_integrations and from set_agent_skills by resource, so an agent can route without opening a schema.

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?

The operation's behavior is well described (full replacement; empty list clears everything), which implies when to reach for it, but there is no explicit when-to-use vs. alternatives such as list_agent_integrations or get_agent, and no stated prerequisites. Usage is left to inference.

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