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

With no annotations, the description carries the burden and does well: it names the data source (SEC EDGAR), license (Free, CC BY 4.0), cadence (this week), and states every row links to its filing plus that the reply opens with a one-line answer and its date. It does not restate read-only/cost characteristics, but a 'get/Answers' framing makes the read-only nature clear.

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?

Front-loads the core question and stays short. Minor waste in the standalone fragment 'Restructuring.' and the choppy separator style, but every remaining clause (source, license, row linkage, reply shape) 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?

No output schema exists, so the description must convey return shape, and it does: a one-line answer with date, rows linking to filings, plus the schema's total/returned/truncated and 'more' behavior. Sufficient for a single-parameter read tool; only minor gaps remain around ordering/recency guarantees.

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%, so the single 'limit' parameter (default 50, ceiling 200, truncation/more link) is fully documented in the schema. The description adds no parameter meaning beyond that, so 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?

States a specific verb+resource framed as a question: 'Which public companies reported restructuring costs this week?', tightly scoped to SEC 8-K Item 2.05 exit/disposal costs. The niche (restructuring costs) is distinguishable from siblings like get_mergers or get_breaches, though no sibling is named 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?

Usage is implied by the natural-language question framing, so an agent can infer the query it satisfies. However, there is no explicit when-to-use/when-not guidance and no routing to related siblings such as get_mergers, which may overlap for layoff/exit events.

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