getTipRanksPointInTimeRatingsByAnalyst

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

Annotations already declare readOnlyHint, idempotentHint and openWorldHint, so the safety profile is covered. The description still earns credit by disclosing the result shape (one row per symbol, latest active call, price target, track-record statistics) in the absence of any output schema, though it says nothing about pagination or rate limits.

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 sentences, front-loaded with the core purpose before the return-value detail, with no filler. Slightly verbose in citing the vendor API name, but nothing is wasted.

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 usefully characterizes the returned rows and statistics, and all five parameters are covered by the schema. Minor gaps around pagination behavior and the meaning of the default snapshot are the only omissions for a tool of this complexity.

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 every parameter (date, page, limit, expertUID, nonadjusted) is already documented in the schema. The description adds no format or syntax detail beyond that, 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+resource: a point-in-time summary of a single analyst's ratings, returning one row per covered symbol with latest call, price target and track-record stats. The 'ByAnalyst' scope is inferable against the sibling getTipRanksPointInTimeRatingsBySymbol, but the description never names or contrasts that sibling explicitly, so it stops short of full differentiation.

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 when-to-use guidance is given. It never explains when this analyst-scoped view is preferable to getTipRanksAnalystSummary, searchTipRanksAnalystRatings, or the symbol-scoped variant. The only routing hint ('as returned by lookupTipRanksAnalyst') lives in the schema, not the description.

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