x402node_convert_timestamp

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

No annotations are provided, so the description must disclose behavioral traits. It mentions an unknown price and auto-pay mechanism, which hints at cost but is vague. It does not specify idempotency, error handling on invalid input, or output format. The description lacks important behavioral context for a conversion 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?

The description is front-loaded with many repetitive synonyms, which is somewhat redundant. The core conversion sentence and auto-detect note are concise, but the price line feels tacked on. It could be more streamlined without losing clarity.

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 output schema, the description fails to explain the return value format or error behavior. It is adequate for input but incomplete for output context. Additionally, it does not differentiate from the many sibling time tools, leaving the agent to guess when to use this converter over others.

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?

The input schema has 100% coverage with a clear description for the single parameter 'value'. The description adds value by stating 'Auto-detect input format', which goes beyond the schema's literal description and clarifies the tool's flexibility.

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 uses multiple clear synonyms and explicitly states the core function: 'Convert between unix epoch (sec or ms), ISO 8601, and human-readable date strings.' It distinguishes itself from sibling tools like timezone-convert or business-days by focusing on timestamp format conversion.

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 usage for conversions with 'Auto-detect input format', but it does not provide explicit guidance on when to use this tool versus sibling time tools (e.g., x402node_time_timezone-convert for timezone conversion, x402node_time_business-days for business day calculations). No exclusions or alternatives are stated.

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