validate_pin_pad_mapping

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

With no annotations provided, the description carries the full burden for behavioral disclosure, but it only says 'validate.' It does not state whether the operation is read-only, what the output format is, what constitutes successful validation, or what happens on failure. 'Validate' implies a check, but the specific behavioral traits are left entirely unspecified.

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

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

The description is a single sentence with no extraneous words, and the active verb 'Validate' is front-loaded. However, it is under-specified and the phrasing 'embedded attached pattern' is awkward. Being short is not the same as being well-structured when key information is missing.

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

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

Given no annotations, 0% parameter coverage, and a tool with three parameters and an output schema, the description is far too minimal. It fails to explain how to provide inputs, what the validation process involves, or how results are reported. The tool is incomplete even for basic agent selection and invocation.

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

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

Schema description coverage is 0%, and the description does not explain any of the parameters (name, path, stable_id). It is unclear how these parameters identify the component or pattern, or whether they are alternatives or complementary. The description adds no semantic value beyond the bare parameter names in the schema.

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

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

The description clearly identifies the tool's specific action: validating component pin numbers against pads of a pattern. It uses the verb 'validate' and names the relevant resources, which distinguishes it somewhat from generic validation tools. However, the phrase 'embedded attached pattern' is jargon-heavy and doesn't fully clarify the exact object being validated.

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

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

No guidance is provided on when to use this tool versus alternatives like validate_library_pattern or validate_library_component. The description implies its use context but gives no exclusions, prerequisites, or decision criteria, so an agent cannot easily determine if this is the right tool.

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