get_composite_latest

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

No annotations are provided, so the description carries the full burden. It explains the composite's meaning but does not disclose operational details such as response format, rate limits, or side effects. However, as a zero-parameter read operation, the absence of behavioral warnings is acceptable, and the output schema covers return structure.

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?

Two sentences efficiently state the action and provide definitional context with no filler. The first sentence tells exactly what the tool does, and the second adds useful context about what SIT-Composite represents.

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 zero-parameter nature and presence of an output schema, the description adequately covers purpose and context. The explanation of SIT-Composite provides meaningful domain context, and no additional details are needed for this simple read-only tool.

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?

There are no parameters to explain; schema coverage is 100% vacuous, and the baseline for zero-parameter tools is 4. The description adds no parameter-specific info, which is appropriate.

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 states the tool retrieves the current SIT-Composite index value and its per-tier breakdown, using the specific verb 'Get' and a named resource. The 'current' qualifier distinguishes it from sibling get_composite_history.

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 does not explicitly provide when-to-use guidance or alternatives, but the 'current' qualifier implies a contrast with historical queries. However, it doesn't explicitly mention when to use this vs sibling tools, so usage context is implied rather than stated.

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