indicator_cci

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

No annotations are provided, so the description carries full burden. It only mentions data point requirement but fails to disclose that this is a read-only calculation, whether it has side effects, or any other behavioral traits beyond the prerequisite.

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 extremely concise with two short sentences, front-loading the tool name and core requirement. No unnecessary information.

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 no output schema and no annotations, the description is incomplete. It does not mention return format (e.g., a single number or array), the mathematical basis, or typical use cases. A more complete description would explain what CCI is and what the output represents.

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 coverage is 100% with descriptions for both parameters. The description adds the constraint that the candles array must have at least 'interval' elements, which is not explicitly stated in the schema (schema only says candles minItems=1 and interval min=2). This adds meaningful semantic context.

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 names the tool as CCI (Commodity Channel Index), which is a specific technical indicator. It distinguishes from sibling indicators by naming the specific calculation, but does not elaborate on what CCI measures, assuming domain knowledge.

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 states a prerequisite (requires at least interval data points) but provides no guidance on when to use CCI vs alternative indicators like RSI or MACD. No exclusions or alternatives are mentioned.

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