get_technical_indicators

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

Without annotations, the description carries the burden. It discloses the paid requirement and lists the indicators returned, which adds transparency. However, no information about rate limits, authentication, or side effects is provided.

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 with no unnecessary words. It front-loads the important paid requirement and lists the indicators 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?

Despite having an output schema, the description omits explanation of parameters and usage context. With three parameters and no descriptions, the agent lacks guidance on how to use the tool effectively.

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 0%, meaning no parameter descriptions in the schema. The description does not explain the three parameters (ticker, period, interval) at all, failing to add any meaning beyond the schema structure.

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 lists the specific technical indicators (RSI, MACD, ATR, EMAs, Fibonacci) that the tool provides, which clarifies its purpose beyond the tool name. However, it lacks a clear verb-resource structure like 'Get technical indicators for a ticker'.

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 mentions 'Paid Fintools MCP required', which is a usage constraint but offers no guidance on when to use this tool versus sibling tools like get_trend_score or get_support_resistance.

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