watchlist_add_bulk

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

With no annotations provided, the description carries the full burden of disclosing behavior, but it only restates the core action. It does not mention whether duplicates are ignored, whether existing watchlist contents are preserved, how invalid symbol formats are handled, or what the mutation implies for the current TradingView session.

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 a single front-loaded sentence with no filler. Every word earns its place and the key information is immediately visible.

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?

The tool is simple with one well-covered parameter and no output schema, so the description is minimally viable. However, with no annotations, an agent still lacks guidance on expected return value or failure behavior, leaving the definition just adequate rather than complete.

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 100%, so the schema already documents the symbols parameter with examples. The description adds no parameter-level detail beyond the word 'multiple', so the baseline of 3 is appropriate.

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 names a specific verb ('Add'), a specific resource ('TradingView watchlist'), and a specific scope ('multiple symbols'), which clearly differentiates it from sibling watchlist_add (single) and watchlist_remove/get. An agent can identify what this tool does without inspecting the schema.

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 intended use is implied by 'multiple symbols' and the existence of watchlist_add, but the description never explicitly states when to prefer this tool over the singular watchlist_add or how it should be used in a batch workflow. No alternatives or exclusions are mentioned.

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