get_unlock_window

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

Annotations already supply readOnlyHint=true, so the description's 'Read-only: issues only Get commands' is largely a restatement. It does add genuine context beyond annotations, though: the data sources (paginated GetTimeSpecGroups, managed time specs and holidays), the derivation chain, and evaluation against the host clock. These are useful behavioral details.

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 purpose is front-loaded, but the body is a single run-on sentence dense with nested parentheticals and repeated group names, making it hard to parse. Roughly the right size, but structurally strained.

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?

With no output schema, the description carries the burden of describing returns and does so in detail: the portal group, its members, time specs/holidays, the derived window, and the active-now boolean. Only the sibling differentiation is missing.

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?

Parameter count is zero and schema coverage is 100%, so the baseline is 4. The statement 'No parameters required' adds nothing beyond an empty schema, but no penalty is warranted for a parameterless tool.

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 gives a specific verb ('Reports') and resource ('the managed unlock window') and elaborates the exact contents returned. However, it never distinguishes itself from the closely-named sibling get_daily_unlock_window, so an agent cannot tell the two apart from the text alone.

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 and no mention of alternatives. The only contextual note is 'No parameters required,' which is a schema fact rather than usage direction. With a near-twin sibling 'get_daily_unlock_window' present, the absence of any routing guidance is a real gap.

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