getSymbolMasterBySymbolID

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

With no annotations, the minimal description does not disclose behavior such as what happens if the symbol ID is not found, whether it returns null or errors, or any side effects. As a read operation, it could benefit from noting it is read-only.

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?

The description is a single sentence with no unnecessary words. However, it could be expanded slightly to include return behavior or error conditions without losing conciseness.

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?

Given no output schema and no annotations, the description does not specify what the tool returns (e.g., the full Symbol Master object). This leaves the agent uncertain about how to use the result.

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%, and the parameter description 'The Symbol ID to search for' is clear but adds no extra meaning beyond the schema itself. Baseline score of 3 is appropriate.

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 'Get Symbol Master by its Symbol ID' clearly specifies the verb 'Get' and the resource 'Symbol Master' with the identifier 'Symbol ID'. It is distinct from sibling 'getSymbolMasters' (which implies getting all masters), but does not explicitly differentiate itself.

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 guidance is provided on when to use this tool versus alternatives like 'getSymbolMasters' or 'getSymbolInstances'. There is no mention of prerequisites or context for use.

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