get_stock_price

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

No annotations exist, so the description carries the full burden. It does disclose that results come back 'directly as text' rather than structured data, which is useful. It says nothing about data freshness/delay, rate limits, or auth requirements, which matter for a market-data tool.

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?

Front-loaded with the core purpose and compact overall. The second sentence partly restates the first (price/day change/key metrics), a minor redundancy rather than bloat.

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?

An output schema exists, so return-value detail is largely handled elsewhere; the description still names the main fields. For a one-parameter lookup tool this is nearly sufficient, with only freshness/auth caveats missing.

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 0%, so the schema gives no help for the single ticker parameter. The description compensates by supplying concrete example formats including an exchange-suffixed symbol (AAPL, RELIANCE.NS), clarifying accepted syntax beyond the bare 'string' type.

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') and resource ('current stock price') plus what payload comes back (day change, key metrics). It is distinguishable from siblings like get_stock_history or analyze_stock, though it never explicitly contrasts itself with them.

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 phrase 'Quick lookup tool' implies this is for fast, single-ticker spot checks, which is a usable usage cue. However, it gives no explicit when-to-use vs when-not guidance or names alternatives such as get_stock_history for trend data.

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