validate_netlist

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, so the safety profile is covered. The description adds the useful detail that validation is against a formal schema, but it says nothing about what a failing netlist yields or how results are reported.

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?

A single front-loaded sentence with a clear verb, object, and standard. No filler, no redundancy; every word earns its place.

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?

The netlist is a nested object and there is no output schema, so the description should ideally indicate what validation returns (pass/fail, error list) and whether it mutates or stores anything. Annotations cover safety, but the result contract is left unspecified.

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?

There is a single required parameter with 100% schema description coverage ('Netlist dictionary containing connections list with net and points'), so the schema carries the semantics. The description adds nothing beyond that, making the baseline 3 correct.

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 names a specific verb ('Validate') and resource ('a hardware netlist dictionary') and scopes the operation to the 'CircuitAgent JSON Schema specification', so the agent knows exactly what this does. It implicitly contrasts with siblings like diff_netlists, but never names an alternative, so it misses the top band.

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?

Usage is only implied: validating against a schema suggests using it as a conformance gate before export/synthesis, but there is no explicit when-to-use, no exclusions, and no mention of diff_netlists or run_erc as alternatives. Adequate but with clear gaps.

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