TDQS

C2.8/5.0
Behavior3/5

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

Annotations already cover read-only, idempotent, non-destructive behavior. The description adds the 'bounded' qualifier, hinting at limits, and the schema exposes edgesLimit/nodesLimit defaults, but the description does not explain truncation behavior or what 'bounded' means in practice.

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?

Single front-loaded sentence with no wasted words. Slightly too terse to carry the required information, but structurally clean.

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

Completeness2/5

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 described, but for a graph tool with five parameters and many overlapping siblings, the description leaves routing and 'bounded' behavior unexplained. Inadequate for the tool's complexity.

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

Parameters3/5

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

Schema description coverage is 100% and each parameter (scope, workspace, edgesLimit, nodesLimit, granularity) is documented in the schema. The description adds nothing beyond naming scope and granularity, so baseline 3 applies.

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

Purpose3/5

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

States a verb (returns) and resource (dependency graph) with scope/granularity qualifiers. However, it does not distinguish from near-siblings like get-symbol-dependencies, get-symbol-dependents, or find-dependency-cycles, so an agent cannot easily tell which dependency tool to pick.

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?

No when-to-use guidance and no alternatives named despite many overlapping dependency siblings. The agent gets no routing information.

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