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

The description simply repeats the delete action without disclosing behavioral traits beyond the annotations. It does not mention irreversibility, ownership requirements, or any side effects. The title mentions 'clé API, scope write' but the description omits this, leaving out important context about authorization.

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 short and front-loaded with the primary English sentence. The subsequent French sentence is a direct translation and somewhat redundant, but it's still concise and doesn't waste much space.

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 destructive operation with no output schema, the description is incomplete. It doesn't mention return values, error conditions, or prerequisites such as authentication scope. The reference to a sibling tool adds minimal context. Overall, it's not enough to fully guide invocation.

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 compensate. It only says 'by id' which adds minimal meaning about the watchlist_id parameter. It doesn't explain what the id is, where to find it (e.g., from pro_watchlist_list), or any constraints on its format.

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 'Delete a watchlist by id.' This specifies the action (delete), the resource (watchlist), and how it's identified (by id). It distinguishes itself from sibling tools like pro_watchlist_create and pro_watchlist_list by making the deletion action explicit.

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 description provides no guidance on when to use this tool versus alternatives. The 'cf. pro_watchlist_list' reference merely points to a related tool but doesn't serve as a usage guideline or exclusion. No prerequisites or conditions for deletion are mentioned.

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