sleep

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

No annotations are provided, so the description carries the full behavioral burden. It directly states that execution pauses for a number of seconds, and for a simple sleep operation the core behavior is clear without hidden side effects or destructive implications.

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 one short, direct sentence with no filler. The action, target, and unit of measurement are front-loaded, and every word contributes to the meaning.

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?

For a single-parameter utility with an output schema, the description plus schema is sufficient to make a correct call. The only notable missing context is usage guidance relative to condition-based wait tools, which is already reflected in the usage guidelines score.

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 description coverage is 0%, so the description should compensate by adding meaning to the 'seconds' parameter. It only paraphrases the schema's field name and adds no constraints about range, decimals, positivity, or maximum allowed values.

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 names a specific verb ('Pause'), a target ('execution'), and the exact duration unit ('seconds'). This clearly distinguishes it from the conditional wait_for_element_* and assert_* sibling tools.

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 gives no guidance about when to use a fixed sleep versus the many wait_for_* alternatives. The agent is left to infer that sleep is a condition-free delay rather than an element/text wait, which is a meaningful usage gap in automation.

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