ta_slug_sma_latest

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It merely states the output is the latest SMA datapoint, but does not mention if the operation is read-only, what happens if no data exists, or any side effects. This minimal transparency is insufficient for an agent to understand the tool's behavior.

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, but it is not well-structured; it is a fragment lacking sentence form. While conciseness is valued, the brevity sacrifices clarity. Every word is used, but it does not earn its place by providing sufficient 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 the tool has 6 parameters and no output schema, the description is severely incomplete. It fails to explain what the tool returns (e.g., a single numeric value or an object), how parameters like 'window' and 'fetchInterval' affect the result, or any constraints. The description is inadequate for an agent to use the tool correctly.

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 100% description coverage, so each parameter is already documented. The description 'Latest SMA datapoint' adds no additional meaning beyond the schema. It implies the 'slug' parameter identifies the asset, but this is already clear. Baseline 3 is appropriate as the description does not add value.

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 'Latest SMA datapoint' indicates the tool returns the most recent SMA value, which is a specific verb+resource. However, it does not explicitly state that it is for a given asset slug and optional parameters, nor does it clearly distinguish itself from sibling tools like 'ta_slug_sma' (which likely returns the full SMA series). The purpose is vague and lacks specificity.

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?

No guidance is provided on when to use this tool versus alternatives such as 'ta_slug_sma' for historical data or other indicator tools. The description does not mention any prerequisites or context for usage, leaving the agent without direction on tool selection.

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