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

With no annotations, the description must disclose behavioral traits. It mentions ordering (most recent first) and scope (all sources), but does not address authentication needs, rate limits, pagination, or whether the returned list is exhaustive (beyond a default limit of 20). The absence of such context limits transparency.

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 a single sentence, concise and front-loaded. However, it omits key information about parameters and does not structure additional details (e.g., bullet points). While not overly verbose, it lacks completeness.

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 sibling tools and the presence of an output schema, the description should provide enough context for correct tool selection and invocation. It fails to describe the filtering capability (type) and result limit, and offers no guidance on alternative tools for different queries. This makes it incomplete for agents.

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 has 0% parameter description coverage, and the description does not mention the 'type' or 'limit' parameters. An agent cannot infer that 'type' filters by opportunity category or that 'limit' controls result count. This is a critical gap.

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 states the tool lists the newest opportunities across all sources, sorted most recent first. This distinguishes it from sibling tools like list_upcoming_deadlines (deadline-focused) and search_opportunities (search-based). However, it does not explicitly note that it returns a limited set or that it can be filtered by type.

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 guidance is provided on when to use this tool versus alternatives such as search_opportunities for keyword search or list_upcoming_deadlines for deadline-oriented queries. Agents are left to infer usage context from the tool name and description alone.

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