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

No annotations are provided, so the description carries the full disclosure burden and does almost none of it: no indication of read vs write, permissions, pagination, or failure behavior. It also conflicts with the schema, which exposes campaign/ad-group and notification_message parameters that do not fit a plain inbox read.

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 short clause with no filler, so nothing is wasted. However, brevity here reflects under-specification rather than disciplined editing; there is no front-loaded statement of what the tool actually does.

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?

With no annotations, no output schema, and four non-obvious parameters, the definition needs far more than one sentence. The agent has no way to know the return shape, whether calling it mutates anything, or how its parameters relate to an inbox read.

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 all four parameters are documented in the schema itself, and the baseline of 3 applies. The description adds no parameter context, and notably does not explain why inbox-alias parameters include adam_id, campaign_id, ad_group_id, and notification_message.

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 identifies the tool only relationally: it is an alias of get_inbox with the "same inbox API." That tells an agent which sibling it duplicates, but never states in its own words what the tool returns or does (list notifications, read inbox messages), and the name list_notifications is not reconciled with the inbox framing.

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?

Saying "Alias for get_inbox" implies interchangeability but gives no rule for when an agent should pick this name over get_inbox, and no exclusions or preconditions. The agent must guess whether this is a deprecated shim, a preferred entry point, or identical in behavior.

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