List check status flips

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 discloses that the tool returns status change history and specifically 'up/down flips,' which is useful. However, it does not mention return format, pagination, or any limitations beyond the schema's seconds parameter. For a read-only operation, this is adequate but not rich.

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, front-loaded sentence with no filler. Every word contributes to understanding the tool's purpose and scope. Perfectly concise for the complexity.

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?

The tool is simple (2 params, no output schema) and the description covers the core behavior. It lacks explicit return structure, but the phrase 'status change history' gives sufficient expectation for a list of flip events. It does not mention prerequisites like check existence, but for a simple list operation this is not critical. Overall, it is complete enough for an agent to select and invoke the tool correctly.

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 50% (only seconds has a description). The description does not directly explain parameters, but the phrase 'for a check' clarifies that uuid refers to a check identifier, adding some value. It does not elaborate on uuid format or offset behavior of seconds. Given the midpoint coverage, the description neither fully compensates nor is redundant.

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 explicitly states 'List status change history (up/down flips) for a check,' which clearly identifies the verb (list) and resource (status flip history for a check). It distinguishes itself from sibling tools like list_checks (which lists checks) and get_check (which retrieves current check details).

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 implies usage for a specific check via 'for a check' but does not explicitly state when to choose this over alternatives, such as get_check for current status. It offers no exclusions or alternative tool guidance, leaving the agent to infer from context.

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