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

Annotations already declare destructiveHint=true and openWorldHint=true, so the description is not required to re-state danger, but it adds very little: the '(MCP confirmation)' note is the one useful addition. It never says what a disconnect actually revokes/deletes, whether it is reversible, or how idempotency_key behaves on retries — material gaps for a destructive multi-action tool.

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?

It is a single compact sentence with no filler, but it is a flat comma-list of five operations with no structural grouping, so an agent cannot easily map each clause to the required parameter set. Brevity here shades into under-specification rather than efficiency.

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 destructive, open-world tool with five distinct actions, 7 parameters, 0% schema description coverage and no output schema, the description should at minimum state per-action required fields and the confirmation/retry flow. As written, an agent knows the menu of actions but not how to satisfy any one of them correctly.

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 0% across 7 parameters, so the description must carry the load and largely does not. It only loosely gestures at ad_accounts ('select ad accounts') and request ('complete/skip integration requests'); it never explains which of connection/request/provider apply to which action, nor what the required idempotency_key means in practice.

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 enumerates the five concrete operations (disconnect, retry disconnect, select ad accounts, complete/skip requests) which map exactly to the action enum, giving a specific verb+resource picture. It does not name the nearest siblings (connections_connect, connections_list, connections_action_run) so the boundary with those tools is left implicit.

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 explicit when-to-use / when-not guidance and no mention of the sibling tools (connections_connect, connections_action_run, connections_actions) that an agent must choose between. The only contextual hint is '(MCP confirmation)' beside disconnect, which implies a confirmation step but does not say how to obtain it or when retry_disconnect is appropriate.

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