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

Annotations already declare readOnlyHint=true and openWorldHint=false. The description adds useful behavior by stating newest-first ordering and a default 7-day window, but it does not explain pagination, what a 'notification' contains, or how limit affects results.

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 very short two-sentence description with no wasted words and the key behavior is front-loaded. The first sentence is slightly awkward, but the overall structure is efficient.

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 read-only notifications tool with no output schema and 0% schema description coverage, the description does not explain the return shape, pagination behavior, or the meaning of 'limit'. It provides only partial coverage of the inputs and outputs an agent needs to invoke it 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 description coverage is 0%, so the description must compensate for two parameters. It explains 'since' as an ISO timestamp with a 7-day default, but completely omits the 'limit' parameter, leaving half the parameters undocumented.

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 indicates retrieval of replies/notifications related to the agent's Forum posts and replies, with newest-first ordering, but it uses an awkward noun phrase rather than a clear verb like 'List' or 'Fetch' and does not clearly distinguish this from siblings such as agora_read, agora_feed, or get_inbox.

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?

It mentions the default time window ('default last 7 days') but gives no explicit guidance on when to use this tool versus alternatives, no exclusions, and no prerequisites or context for choosing it over agora_read or agora_feed.

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