TDQS

B3.4/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds that results prioritize infrastructure, which is useful behavioral context, but it does not disclose search scope beyond that or mention auth/rate-limit behavior.

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

Conciseness5/5

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

The description is two short sentences with no wasted text. It front-loads the concrete resources being located and then adds the prioritization note.

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

Completeness4/5

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

For a low-complexity, read-only discovery tool with an output schema and fully described optional parameter, the description is mostly complete. It says what kinds of sources are located and that infrastructure is prioritized, though it leaves the exact search behavior and usage conditions implicit.

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?

There is only one optional parameter, context_id, and the schema description coverage is 100%. The tool description adds no additional parameter guidance, so the baseline score of 3 applies when the schema already carries the parameter semantics.

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?

The description states a specific verb, 'Locate', and specific resources, '.tfvars' and 'VERCEL_* references', with scopes 'per environment' and 'in pipelines'. It does not explicitly name or distinguish itself from nearby siblings such as vercel_env_diff_repo or vercel_env_list, but the purpose is clear.

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?

The description implies the tool is for finding infrastructure and pipeline environment references, but it gives no explicit when-to-use guidance, exclusions, or alternatives. It does not tell the agent when to choose this over vercel_env_list or vercel_env_diff_repo.

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