Chip company SEC filings and revenue

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds meaningful context beyond that: the upstream data source (SEC EDGAR), the form types returned, the exact coverage universe, and a deliberate data gap (no stock prices). It still omits pagination/limit behavior, but with annotations present this is a solid addition.

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 tightly-packed sentences with zero waste; the resource and data source are front-loaded, and the exclusion is a natural trailing clause. Nothing could be cut without losing information.

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 description establishes data source, covered entities, and one exclusion, which is good. But with 0% schema coverage and no output schema, it leaves the calling behavior of `limit` (max 30) and `includeRevenue` unexplained, so an agent still has gaps to call it optimally.

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 0%, so the description must carry parameter meaning. It partially compensates: the ticker list constrains valid `ticker` values and the enumerated form types inform the `forms` parameter. But `limit` and the non-obvious `includeRevenue` boolean are left entirely unexplained.

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?

States a specific verb+resource: retrieves recent SEC EDGAR filings (10-K, 10-Q, 8-K, etc.) and annual reported revenue. It also enumerates the exact company set covered, which pins down scope tightly and clearly separates it from news- or briefing-oriented siblings.

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?

Usage is implied by the resource ('filings and revenue for these tickers'), and there is one useful negative boundary: stock prices are excluded. However, no alternative is named and there is no explicit when-to-use or when-not-to-use guidance relative to siblings like chip_news or chip_briefing.

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