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

Annotations already declare readOnly=true, idempotent=true, destructive=false, openWorld=true, so the safety profile is fully covered. The description adds genuinely new operational context: the content surface returned (markets, products, ratings) and an explicit per-run cost of 5 points, which matters for an agent budgeting calls.

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?

Two compact sentences with the purpose and the returned data front-loaded, followed by the cost. No filler, nothing that fails to earn its place.

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?

With no output schema, the description does the right thing by enumerating what comes back (markets, products, ratings), and the single required parameter is documented in the schema. What is missing is any note on failure modes (invalid alias) or how a vendor relates to its product profiles, but for a one-parameter read tool this is close to sufficient.

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% and the schema itself supplies the alias/URL semantics plus an example ('forcepoint'). The description only restates 'by alias or URL', adding no format, normalization, or error-handling detail beyond the schema, so the 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 (Get) plus resource (Gartner Peer Insights vendor profile) and names the payload returned: markets, products, and ratings. It clearly distinguishes a *vendor* profile from sibling tools like run_gartner_product or run_gartner_market, though it never names those siblings explicitly.

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 specifies accepted input forms (alias or URL) but gives no when-to-use guidance and no routing against the many sibling Gartner tools (run_gartner_product, run_gartner_markets_search, run_gartner_market_products). The 'flat 5 points' note is cost, not usage guidance.

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