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

With no annotations provided, the description carries the full behavioral disclosure burden and does so well by detailing the scope and update cadence of each data category, such as ClinicalTrials.gov updated weekly, PubMed daily, KIPRIS monthly, and KRX KIND daily. It is a read-style tool by nature, and the description's inventory makes the behavior predictable, though it does not cover error behavior or response size.

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 dense sentence but front-loads the core purpose and then organizes the profile contents in a logical catalog. Every clause adds concrete information; the only minor weakness is that the long list of parenthetical sources and update frequencies makes it heavier to parse than necessary.

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 that there is no output schema and no annotations, the description is remarkably thorough about what the returned profile will cover and how current the data is. It also prevents misuse by redirecting live-quote needs to get_stock_quote. It would be more complete with a note on response shape or error conditions, but those are not essential for correct tool selection.

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 the input schema already fully explains 'identifier' and 'language.' The description does not add parameter-level meaning beyond what the schema provides, so the baseline score of 3 is appropriate.

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 opens with a specific verb and resource: 'Full profile of one company,' and then enumerates what that profile contains (overview, products, R&D, financials, regulatory record, trials, publications, patents, disclosures). It is clearly distinguished from get_stock_quote by naming the sibling explicitly for live quotes.

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?

The description makes the primary use case explicit: retrieve a comprehensive profile of one company. It also provides a direct routing rule by stating 'For the live stock quote use get_stock_quote,' which is an explicit when-not alternative. This is sufficient even though other siblings are not individually mentioned.

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