get_morning_brief

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

The description discloses the output format (structured JSON + morning_text) and lists the data components, but does not explicitly state read-only behavior, authentication needs, or data freshness. Without annotations, these gaps reduce transparency for an agent.

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 very concise, using a clear bullet list to enumerate components, and front-loads the key purpose. No wasted words, and the output format is described efficiently.

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 description covers the tool's purpose, the data components it includes, and the output format. Given the output schema exists, it need not detail return types. Minor gaps: no mention of data freshness or prerequisites, but largely 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?

The tool has zero parameters, so the schema coverage is trivially 100%. The description appropriately omits parameter details, and no additional meaning is needed.

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 explicitly states the tool compiles a comprehensive pre-market brief for Indian traders, listing specific components. It is clearly differentiated from sibling tools like get_morning_fno_brief and get_stock_brief by its scope and timing.

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 use for pre-market briefing at 8:15 AM but does not explicitly state when to use this tool over alternatives or when not to use it. No exclusion criteria or comparisons to other briefs are provided, leaving the agent to infer from the name.

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