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

Annotations already declare destructiveHint=true, so the agent knows this is a mutating operation. The description adds useful context by mentioning supported varieties and the return of an order ID, but it does not disclose additional behavioral traits like margin requirements, failure modes, or exchange-specific restrictions. No contradiction exists.

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 two short sentences, immediately front-loading the core purpose. Every word contributes meaning, with no fluff or repetition of schema content. It is appropriately concise given the rich schema.

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 schema is detailed and annotations cover the destructive nature, but the description omits critical contextual info such as the need for prior login and the conditional parameter requirements (e.g., triggerprice for SL orders, price for LIMIT orders). The tool has 14 parameters and 9 required fields, and the description does not clarify any interdependencies, leaving a completeness gap for an agent.

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 description coverage is 100%, so the baseline is 3. The description only restates the variety enum (which the schema already documents) and adds no deeper parameter semantics, such as conditional dependencies between order types and trigger prices. It does not significantly go 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 states a specific verb and resource: 'Place a buy/sell order on Angel One.' This clearly distinguishes it from sibling tools like modify_order and cancel_order, and it explicitly mentions supported order varieties. A clear, non-tautological purpose is provided.

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 its use for placing new orders, but it does not explicitly state when to use this tool versus alternatives such as modify_order or cancel_order. No exclusions or conditions are given, leaving the guidance at an implied level.

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