cap_watchlists_create

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

With no annotations, the description carries full burden. It discloses name length and occasional confirm requirement, but does not explain 'when configured' or what confirm does, nor does it discuss idempotency, error handling, or platform-specific behaviors.

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 extremely concise, with a single sentence that includes a parenthetical constraint. Every word is necessary, and the key action is front-loaded. No redundant 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?

Given the tool has 2 parameters and an output schema, the description provides minimal context. It covers creation and basic constraints but lacks details on parameter behavior, error cases, or output format. It is adequate but incomplete.

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 0%, so description must compensate. It adds meaning by linking 'name' to 1-100 chars and implying 'confirm' relates to configuration, but does not explain the boolean's purpose or value semantics, leaving significant ambiguity.

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?

Description clearly states 'Create a new watchlist' with specific verb and resource, and includes constraints (1-100 chars). It distinguishes from sibling tools like cap_watchlists_delete, get, list, add_market, and remove_market by focusing on creation.

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 implies when to use (to create a watchlist) and mentions 'requires confirm when configured', but does not explicitly state when not to use or alternative tools. Usage context is implied but not fully detailed.

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