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

With no annotations provided, the description carries the full burden of behavioral disclosure. It merely states the tool searches press releases and does not mention pagination, date range behavior, rate limits, return format, or any side effects. This lack of detail is insufficient for an unannotated 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?

The description is concise at two sentences and front-loads the primary verb and resource. However, the second sentence is somewhat redundant with the first and introduces the inaccuracy about 'company name', making it less efficient than it could be.

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?

Given the tool has five parameters, no output schema, and no annotations, the description provides minimal context. It does not explain how results are returned, how to handle pagination, or how the date filters work. The existence of similar sibling tools further underscores the need for more complete guidance, which is absent here.

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?

The input schema documents all five parameters fully, so the baseline is 3. The description adds context by mentioning 'stock symbol or company name', but the 'company name' part is inaccurate because the schema only supports symbols. It does not clarify the meaning of 'to', 'from', 'page', or 'limit' beyond what the schema already provides.

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 clearly identifies the action ('Search') and resource ('company press releases'), and conveys the use case of finding corporate announcements. However, it does not distinguish this tool from the sibling tool 'getPressReleases', and the mention of 'company name' is misleading since the schema only accepts stock symbols via the 'symbols' parameter.

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?

No explicit guidance is provided about when to use this tool versus alternatives such as 'getPressReleases' or 'searchStockNews'. The description implies a search use case but does not state exclusions or conditions, leaving the agent without clear selection criteria.

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