get_morning_fno_brief

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

No annotations are provided, so the description carries the full burden. It explains that the tool aggregates multiple data points into one call, which is transparent about its behavior. It does not mention any side effects or permissions, but for a read-only data retrieval tool, this is adequate.

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 concise, front-loaded with the core purpose, and uses a bullet list for clarity. Every sentence adds value with 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?

Given the tool has no parameters and a well-defined purpose (morning F&O brief), the description is complete. It covers all major return components, and an output schema exists for additional detail, though not provided here.

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?

The input schema has no parameters (empty properties), so schema coverage is 100%. The description adds meaning by detailing what the tool returns, fulfilling the baseline expectation for a parameterless tool.

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 is an 'F&O-focused morning brief for NIFTY and BANKNIFTY traders' and enumerates the specific sections it compiles (GIFT Nifty, India VIX, etc.). This distinguishes it from sibling tools like 'get_morning_brief' and 'get_nifty_outlook'.

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 it is intended for morning preparations for F&O trading by listing its contents, but it does not explicitly state when to use this tool versus alternatives or provide exclusions. The context is clear enough for an informed agent.

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