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

readOnlyHint annotation already indicates safety. Description adds specificity about trading halt status fields (halted/haltCode/haltedAt) and behavior for halted-but-listed tickers, going beyond annotations.

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?

Two sentences plus a clarifying line about halt status. Front-loaded with key information, no redundant content.

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 presence of output schema, description adequately covers return fields (CIK, exchange, etc.) and highlights special status fields. Lacks mention of error conditions or prerequisites, but sufficient for a simple lookup.

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 covers 100% of parameters with description. The description reiterates ticker symbol usage but adds no new semantics beyond 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?

Clear verb+resource ('Get enriched company profile by ticker symbol'). Distinguishes itself as a lightweight lookup compared to a 'full bundle', though doesn't name the alternative tool explicitly.

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?

Explicit guidance: 'use this when you only need basic company info rather than the full bundle' and mentions credit cost (1 credit). Does not list when not to use but implies scope.

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