stt_winning_products

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

No annotations provided. The description does not disclose behavioral traits such as read-only vs. mutating, prerequisites (e.g., need login), side effects, or what 'open' entails (e.g., navigates to a page?). It only says 'return a snapshot', which is vague.

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 concise sentences. The first states the purpose, the second provides a configuration tip. No wasted words.

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 no parameters and no output schema, the description adequately states the goal but lacks detail on what the snapshot contains (e.g., list of product IDs, full details, etc.). It also does not address potential prerequisites or error conditions. Competent but not fully 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?

No parameters, so baseline is 4 per instructions. The description adds context about an environment variable (STT_WINNING_PATH) that configures behavior, which is a meaningful addition beyond the schema.

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 opens and returns a snapshot of winning/handpicked products from Sell The Trend. It distinguishes from siblings like stt_search_products by implying this is a curated set, not a search. However, it could be more precise about whether 'winning' and 'handpicked' are the same or different.

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?

No guidance on when to use this tool vs. alternatives (e.g., stt_search_products, stt_snapshot). The only hint is a configuration note about .env, which does not help with tool selection.

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