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

With no annotations, the description carries the full burden. It discloses that this is a retrieval (read-only) operation and lists return content, which is helpful given the lack of an output schema, but it omits permissions, rate limits, pagination behavior, and error conditions.

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 well-formed sentences with the core retrieval purpose front-loaded and a useful downstream note about barcodes in the second sentence. No wasted words, and the structure is easy to scan.

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 retrieval tool with no output schema, the description adequately explains what is returned and hints at the subsequent ordering workflow. It could go slightly further by mentioning pagination or authentication, but it covers the essential context an agent needs.

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 both parameters (cr_no and company_name) are fully documented in the schema. The description adds nothing about parameter syntax, formats, or mutual exclusivity beyond what the schema already provides.

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 ('Retrieve') and resource ('full catalog of official ICRIS statutory filed documents for a Hong Kong company'), and enumerates the returned artifacts (barcodes, form codes, filing dates, titles), which clearly separates it from siblings like create_filing_order or search_companies.

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?

Implies usage context by noting barcodes can be used to order official statutory filings, but never explicitly says when to choose this tool over create_filing_order or get_order_status_and_download, nor does it state exclusions or prerequisites.

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