TDQS

D1/5.0
Behavior1/5

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

Tool has no description.

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

Conciseness1/5

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

Tool has no description.

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

Completeness1/5

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

Tool has no description.

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

Parameters1/5

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

Tool has no description.

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

Purpose1/5

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

Tool has no description.

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

Usage Guidelines1/5

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

Tool has no description.

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

D1.6/5.0
Disambiguation3/5

The tools have distinct names (getIncident, getIncidentSample, listIncidents) suggesting different purposes, but without descriptions, it's unclear how 'getIncident' and 'getIncidentSample' differ—they could overlap in retrieving incident data. The 'listIncidents' is clearly separate for listing multiple incidents.

Naming Consistency5/5

All tool names follow a consistent camelCase pattern with clear verb-noun combinations (getIncident, getIncidentSample, listIncidents). There are no deviations in naming style, making them predictable and readable.

Tool Count2/5

With only 3 tools, the server feels thin for an incident management domain, as it likely lacks essential operations like creating, updating, or resolving incidents. This minimal set may not support complete agent workflows, indicating an under-scoped tool surface.

Completeness2/5

Inferred from the domain (incident management), there are significant gaps: no tools for creating, updating, deleting, or resolving incidents, and no coverage for related entities like alerts or metrics. This incomplete surface will likely cause agent failures in handling full incident lifecycles.
