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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds one genuine behavioral fact beyond that: results are "redacted", meaning sensitive connection data is masked — useful so the agent doesn't expect raw credentials. Pagination behavior and scope remain undisclosed.

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 front-loaded phrase with zero waste, which is structurally sound. But at four words it is under-specified rather than concise — there is no second sentence doing the work a listing tool needs.

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 and annotations exist and carry some burden, but with a filter parameter of unknown domain (`channel`), opaque cursor pagination, and an undefined notion of "connection", an agent cannot call this confidently. The description leaves the core semantics to guesswork.

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?

All three parameters (limit, cursor, channel) have 0% schema description coverage and the description explains none of them. In particular, valid `channel` values and the cursor's pagination semantics are undocumented anywhere, and the description does nothing to compensate.

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?

"List redacted platform connections" gives a verb (List) and a resource (platform connections), so the basic operation is understandable. However, "connections" is never defined (linked ad accounts, pages, channels?) and nothing distinguishes this from siblings like connections_check_intent or setup_check_channel_connect, which may also surface connection state.

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 statement of when to call this versus alternatives, no prerequisites, and no mention of the related connection tools (check_intent, create_intent, disconnect_guide). The agent must infer usage purely from the name.

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