get_sector_context

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

With no annotations and no output schema, the description at least signals a read-only lookup and names the two data aspects returned. It does not disclose how as_of_date affects results, what the comparison includes, or the response shape, so behavioral detail remains thin.

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?

One front-loaded sentence contains the essential action and object with no filler. Every word earns its place.

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 two-parameter getter this is minimally adequate: an agent can infer a ticker is required and as_of_date optional by its default. It falls short on distinguishing itself from overlapping siblings and documenting parameter semantics or return content, especially given no output schema.

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 0%, and the description does not explain either parameter. The word 'A-share' hints that ticker identifies a Chinese-listed security, and as_of_date is self-describing to some degree, but the date's format, meaning, and interaction with results are left unresolved.

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?

Names a specific retrieval action ('Get') and a precise object ('concept membership and industry comparison' for an A-share), making the tool's domain unmistakable relative to siblings like get_stock_prices or get_company_fundamentals. The A-share qualifier narrows the target security type.

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 purpose sentence implies the use case: call this when you need a company's sector/concept memberships or an industry comparison. It does not explicitly state when not to use it or which sibling tool is a better alternative, so guidance is only implicit.

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