yahoo_finance_ticker_analysts

Read-only

Fetch Yahoo Finance analyst data for a symbol, including recommendations, upgrades, downgrades, price targets, and estimate modules. Use this for analyst outlook on one security, not its financial statements.

TDQS

A4/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile and external-data nature are covered. The description adds the multi-module scope of what is returned but says nothing about freshness, rate limits, or auth needs. With annotations carrying the main behavioral burden, a 3 is appropriate.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, zero filler. The capability statement comes first and the disambiguation constraint is front-loaded right behind it. Every clause earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return-value detail is unnecessary, and the single required parameter is fully documented in the schema. The description covers purpose, scope, and exclusion adequately for a simple read-only fetch; only minor behavioral context is absent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There is a single parameter with 100% schema description coverage ('Yahoo Finance symbol such as AAPL'), so the schema already documents it fully. The description adds nothing about symbol format or exchange qualification beyond that, which is the expected baseline when the schema does the heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (Fetch) and resource (Yahoo Finance analyst data) and enumerates the payload (recommendations, upgrades, downgrades, price targets, estimate modules). The second sentence explicitly separates it from the financial-statements sibling, so an agent can route correctly without opening schemas.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides a clear positive scope (analyst outlook on one security) and an explicit exclusion (not its financial statements), which maps cleanly onto the sibling yahoo_finance_ticker_financials. It stops short of naming that sibling or any alternative tool directly, so it is strong context rather than full routing guidance.

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