configure_worksheet_time_series

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

With no annotations, the description carries the full behavioral burden, yet it does not disclose that this mutates the workbook, what happens to the existing domain, whether the field must already be continuous, permissions required, or reversibility. It implies a write operation ('extend', 'allow calculations') without characterizing it.

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?

A single front-loaded sentence with no filler, which is structurally fine, but it is under-specified rather than genuinely concise given the tool's complexity. Nothing is wasted, but little is said.

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?

An output schema exists so return values needn't be explained, but for a 5-parameter mutation tool with zero annotation coverage and zero schema descriptions, the definition leaves critical calling information missing. It is not complete enough for reliable invocation.

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?

All 5 parameters have 0% schema description coverage, and the description mentions none of them (field, periods, period_type, calculations_on_densified_marks, worksheet_name). Meaning such as what 'periods' counts or what period_type accepts is completely absent.

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 states a recognizable action (extend a continuous date domain) tied to a resource, but it is vague about scope and offers no differentiation from close siblings like configure_worksheet_domain_range or enable_domain_completion. An agent cannot reliably tell which of these overlapping tools to call.

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?

There is no when-to-use guidance, no prerequisites, and no named alternative. The clause 'allow calculations on added periods' hints at a scenario but never states the condition under which this tool should be chosen over configure_worksheet_domain_range.

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