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

No annotations exist, so description carries full burden. It discloses return value format (size/radix annotation vs plain), and a behavioral constraint (signal must be last, enforced). This is good transparency for a read tool.

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?

Description is concise (10 lines), well-structured with a purpose sentence followed by parameter details in bullet-like format. No fluff, every sentence is informative.

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 the complexity (3 parameters, no annotations, output schema exists but description explains return value), the description is complete. It covers parameter formats, return behavior, and a usage constraint.

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 coverage is 0%, but the description compensates fully: explains signal path format (dot-separated with 'sim.' prefix), time examples ('400 ns'), and radix options. This adds critical meaning beyond the raw 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 states the tool examines a signal value with optional time and radix. It uses specific verb 'Examine' and resource 'signal value', and the context of sibling tools (e.g., vcc_force, vcc_eval) makes its distinct purpose obvious.

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 provides detailed parameter usage: signal format, time semantics (omit for current time), radix options. It also notes a special constraint ('Signal must be last…'). While it doesn't explicitly compare to siblings, the purpose is clear enough.

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