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

Adds substantive behavior the annotations do not: live web search, latency, and a concrete cost of ~165 credits (~$0.165) per call, plus the caveat that hits are unverified leads. However, the description asserts a 'Live web search' while annotations declare openWorldHint=false, which is a genuine mismatch an agent could act on incorrectly.

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?

Three compact sentences: purpose first, then the verification caveat, then the cost. The cost sentence is isolated as a standalone line, which reads cleanly. Minimal waste.

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 an 8-parameter, all-optional, no-output-schema search tool, the description covers the two things an agent most needs warned about: results are unverified and the call is expensive/slow. It does not say what the return looks like or whether the tool is useful with zero parameters supplied.

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 88%, so the schema already carries the parameter meaning (eligibility categories, state pool-size rationale, etc.). The description adds no parameter-level guidance of its own, so baseline 3 applies.

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?

States a specific verb and resource: 'Search for current scholarship pages to review.' It is immediately clear this is a live scholarship-search tool, but it never distinguishes itself from likely-overlapping siblings such as aid or awardlens, so the agent must guess which one to pick.

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?

Gives real usage context: results are 'a research lead, not a verified match,' the agent should confirm terms/deadline/eligibility on the sponsor page before advising, and it flags that live web search is 'slower and costlier than the other analysis tools.' That comparative cost note implies a fallback ordering, but no alternative tool is named explicitly.

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