Behavior2/5

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

No annotations are provided, so the description must convey behavior fully. It only says 'Get', implying read-only, but does not disclose what happens for invalid IDs (error response), whether the output is the full suite object, or any side effects. This is insufficient for complete transparency.

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 a single, concise sentence that immediately states the core purpose. There is no extraneous information; every word is necessary.

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?

Given the low complexity (1 required param, no output schema, no annotations, simple resource), the description is mostly complete. It covers what the tool does and the key parameter. The lack of usage guidance is a minor gap, but the description suffices for a straightforward retrieval tool.

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 coverage is 100% with one parameter 'suite_id' described as 'Suite ID'. The description adds 'by ID' but no additional semantics, format, or constraints beyond the schema. Baseline 3 is appropriate since the schema handles the param documentation adequately.

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

Purpose5/5

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

The description explicitly states 'Get a specific test suite by ID,' clearly identifying the action (get), resource (test suite), and scope (by ID). It naturally distinguishes from sibling tools like 'get_suites' (lists all) and 'add_suite' (creates).

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

Usage Guidelines3/5

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

The description implies usage for retrieving a single test suite by ID, but provides no explicit guidance on when to use this tool versus alternatives, nor any prerequisites or conditions (e.g., 'use when you have the suite_id'). Minimal but adequate for a simple tool.

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