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

With no annotations provided, the description carries the full burden. It discloses the return structure in detail (total_items, data array with specific fields) and notes the 'up to 10 symbols' limit. It does not mention rate limits, error behavior on exceeding 10 symbols, or latency characteristics, but covers the essential behavioral contract.

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 ('Real-time quote data. Retrieve...'). The inline JSON return structure is verbose but necessary given the lack of structured output schema. The sibling tool references are efficiently placed at the end. Slightly dense but information-dense.

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?

Compensates well for lack of annotations and structured output schema by providing detailed return structure inline. Covers the 10-symbol limit and points to related tools. Could be improved with error handling or rate limit notes, but sufficient for a data retrieval 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 coverage is 100%, establishing a baseline of 3. The description adds the critical constraint 'up to 10 symbols' which is not documented in the codes parameter schema. However, it does not elaborate on the boolean flags (settlement, badj, extended, dadj) beyond the schema descriptions.

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 states 'Retrieve real-time quote data for up to 10 symbols' - a specific verb (retrieve), resource (quote data), and scope constraint (10 symbols, real-time). It clearly distinguishes from siblings by naming get_symbol_series for historical data and get_symbol_info for company details.

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?

Explicitly directs users to alternatives: 'For historical data use get_symbol_series. For company details use get_symbol_info.' This provides clear when-not-to-use guidance and names the correct sibling tools for those use cases.

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