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

No annotations are provided, so the description must disclose behavioral traits. It lists outputs but does not mention read-only nature, data sources, limitations, or any side effects. The description gives no insight into how results are computed or what the response structure looks like, beyond the output schema.

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 line that front-loads the purpose ('Volume diagnostic') and then lists specific outputs in a compact, readable list. Every phrase adds information with no redundancy.

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?

The tool is relatively simple with one parameter and has an output schema, so the description doesn't need to explain return values. However, it doesn't clarify what 'top 5min hotspots' or 'peak slot' mean, which could be ambiguous to an AI agent. Considering the richness of the output schema, the description is minimally adequate but leaves room for interpretation.

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?

The schema has one parameter 'symbol' with no description, and schema description coverage is 0%. The description does not mention the parameter at all, relying on the schema's property name. For a trivial parameter this is somewhat acceptable, but the description adds no semantic value beyond the schema.

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 defines the tool as a volume diagnostic and lists specific computed outputs: top 5min hotspots, peak slot, OBV 20-day trend, and today/20-day volume ratio. This distinguishes it from sibling tools focused on other chart patterns or indicators.

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 implies the tool is for volume analysis but provides no explicit guidance on when to use it vs. alternatives like get_technical_indicators or get_market_overview. There are no exclusion criteria or preferred use cases stated.

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