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

The description adds the limitation that coverage depends on public sources and includes pricing and accepted network details. It does not contradict the annotations, but it also gives little insight into side effects, data freshness, pagination, or response behavior beyond what the output schema already provides.

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?

The description is compact and uses labeled sections, but it contains a direct duplication: the first sentence and the 'Use when' sentence are identical. This wastes space and reduces the value of the structure.

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 tool with five optional parameters and no required fields, the description gives a broad outline but leaves key selection context unclear, especially how this search differs from company_fr_legal_announcements_since. The output schema helps with return values, but the description still lacks guidance on family/department formats and minimal filtering requirements.

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?

With 0% schema description coverage, the description partially compensates by mapping the search to 'family, date window and/or department', which loosely explains family_code, since/until, and department. However, it does not clarify valid formats or values for family_code or department, and it omits the limit parameter entirely.

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?

The description clearly states the tool searches BODACC public announcements and names the main filters: family, date window, and department. This is a specific verb plus resource, though it does not explicitly distinguish itself from the sibling company_fr_legal_announcements_since.

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 'Use when' section merely repeats the description rather than giving actual guidance. There is an 'Avoid when' note about legal/regulated decisions, but no mention of when to prefer this tool over siblings such as company_fr_legal_announcements_since or other search-related endpoints.

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