TDQS

B3.3/5.0
Behavior3/5

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

No annotations are provided, so the description carries the burden. 'Query' implies a read-only operation and the default time window ('-24h@h') is disclosed, but there is no mention of required permissions, whether results are paginated, or any rate limits. A return schema exists, which offsets some of the gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The opening sentence front-loads the tool's purpose, and the argument list is compact. Slight redundancy from restating parameters in an 'Args:' block, but nothing is wasted at length.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, return values need not be explained. The description is adequate for invocation but omits sibling differentiation and any indication of permissions or result limits, leaving an agent to guess in a crowded alert-related tool family.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, so the description must compensate, and it largely does: it names all three parameters, gives the accepted severity values ('critical', 'high', 'medium'), and states the default time window. It stops short of explaining Splunk time syntax or what 'count' actually caps, so it is not a full 5.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: 'Query security alerts, high-severity trigger events, and findings.' An agent knows it retrieves security alert data. However, it does not differentiate itself from close siblings like splunk_list_alerts or splunk_get_alert_history, which read as overlapping alert-retrieval tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this versus alternatives such as splunk_list_alerts, splunk_get_alert_history, or splunk_acknowledge_alert. The description only lists parameters, leaving selection entirely to inference.

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