set_currentperiod

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

Warns about potential data loss if periods are removed, which is a critical behavioral trait. With no annotations provided, this disclosure adds necessary transparency, though it could mention other behaviors like idempotency.

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 concise sentence with a critical warning, followed by a clear recommendation. No extraneous information, and the key action is front-loaded.

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 or annotations, the description covers the action, warning, and precautionary step. It could mention return behavior or confirm success, but is adequate for a simple setter 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?

Schema coverage is 100% with detailed parameter descriptions. The overall description adds no additional semantics beyond what the schema already provides for each parameter, resulting in a baseline score.

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 'Set current period for a model' with a specific verb and resource. It distinguishes itself from the sibling tool 'show_currentperiod' by mentioning that tool for reading the current value.

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?

Explicitly advises to 'Use show_currentperiod to see the current value first,' providing clear context for safe usage. However, it does not exhaustively list all alternative tools or conditions for non-use.

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