data_get_indicator

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. The verb 'Get' implies a read-only operation, but the description does not explain what is actually returned, whether there are side effects, or how the response is structured. This is minimal but not wholly absent.

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, efficient sentence with no filler. It front-loads the key action and object, though it could have used the space to disambiguate from sibling tools without becoming verbose.

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?

For a simple one-parameter getter, the description is marginally adequate, but it misses an explicit link to chart_get_state for obtaining the entity_id and does not clarify the distinction between indicator input values and computed study values. Given no output schema, the return format is also left unspecified.

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%, with the entity_id parameter already documented as 'Study entity ID (from chart_get_state)'. The tool description adds no parameter-specific meaning beyond what the schema provides, 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?

The description clearly states the verb 'Get' and the resource 'indicator/study info and input values', making it easy to see this is a retrieval operation. However, it does not explicitly distinguish itself from the sibling data_get_study_values, which could overlap with 'study info' in an agent's mind.

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 description provides no guidance on when to use this tool versus alternatives like data_get_study_values or data_get_ohlcv. The parameter description 'from chart_get_state' implies a prerequisite but the tool description itself lacks any usage context.

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