The hardware truth contract engine for AI engineering agents. Turns raw datasheet PDFs into verified engineering contracts across 16 extraction modules, featuring deterministic spatial document mapping, IPC-compliant PCB footprints, alternate-function matrices, and zero-hallucination mathematical audits.
Scored across 1 tool
With only a single tool, there is no possibility of confusing it with another; its purpose (listing supported hardware extraction modules) is unambiguous.
The single tool uses a clear, readable snake_case verb_noun pattern (datasheetvend_list_hardware_modules) with a consistent server prefix, though there is no broader set to confirm a convention.
A one-tool server sits at the borderline-thin end of the scale; the tool only enumerates module names and offers no operation to actually invoke them.
The surface only lists available extraction modules (KiCad, Pinout, Thermal Limits, Register Maps, etc.) but provides no tool to run any extraction or decode a datasheet, leaving the core domain workflow unreachable.
List all available hardware extraction modules supported by DatasheetVend (KiCad footprints/symbols, Universal Pinout, Thermal Limits, Absolute Maximum Ratings, Timing Characteristics, Logic Levels, Register Maps, Decoupling Passive BOM, Part Number Decoders, etc.).

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, giving a complete safety profile for a read-only list operation. The description adds the domain list of modules but no additional behavioral traits such as pagination, rate limits, or output structure. Baseline 3 is appropriate given the annotation coverage.
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, front-loaded sentence with no wasted text. The parenthetical examples are compact and directly support the purpose of the tool.
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?
For a zero-parameter list tool with an output schema present and annotations that fully describe its safe read-only behavior, the description provides exactly the domain context an agent needs. Return values are handled by the output schema, so no further explanation is required.
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?
This tool takes zero parameters, so there are no parameter semantics for the description to clarify. The baseline of 4 applies because schema and description cover all needed input information by omission.
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 states a specific verb ('List') and resource ('all available hardware extraction modules supported by DatasheetVend'), and then enumerates concrete module categories. There are no sibling tools to distinguish from, and the scope is unambiguous.
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?
The description implies discovery usage but does not state when to call this tool versus alternatives, nor does it include prerequisites or exclusions. With no sibling tools present, the implied usage is adequate but minimal.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
