fetch_watchlist

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

With no annotations provided, the description carries the full burden. It discloses the dynamic source (Chartink scan) and fallback (static NIFTY list), which is transparent. Since it is a read-only fetch with no side effects, no further behavioral details are necessary.

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 sentence that perfectly conveys the purpose and behavior without any wasted words. It is concise and front-loaded.

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 is complete. It explains what the tool returns (watchlist symbols) and its fallback behavior. The sibling tools provide context that this is a basic data retrieval, so no additional details are needed.

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?

There are no parameters, so the baseline is 4. The description adds value by explaining the source of the symbols, which is beyond what the empty schema provides.

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 it fetches watchlist symbols from a specific Chartink scan or a fallback static list. It distinguishes itself from sibling scanning tools like scan_watchlist_for_intraday_opportunities and scan_watchlist_for_swing_opportunities, which search for trade setups rather than returning the watchlist itself.

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 that this tool is used when the agent needs the current watchlist symbols. It does not explicitly state when not to use it or mention alternatives, but given the simplicity of the tool, the guidance is adequate.

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