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

With no annotations, the description carries the transparency burden. It discloses the pay-per-use cost (0.01 USDC on Base) which is useful, but fails to mention any other behavioral traits like whether it's read-only, rate limits, or what happens on failure. The chaining detail adds some transparency.

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 efficient and front-loaded with the primary purpose. The cost note is secondary but relevant. Concise and well-structured.

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 simple one-parameter tool, the description covers the core functionality and pipeline. However, it does not specify the output format or whether both summary and translation are returned together, which is a minor gap. Overall adequate for a demo tool.

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 description 'entrada del pipeline' which is generic. The tool description adds no additional semantics about the format or constraints of the input parameter, so it relies on the schema. Baseline 3 applies.

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 'Summarizes and translates to English' and specifies it chains 'quick-summary -> fast-translate'. It distinguishes itself from siblings like quick-summary and fast-translate by being a combined pipeline.

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 combined summarization and translation but does not provide explicit guidance on when to use this tool versus calling quick-summary and fast-translate separately. No when-not or alternative routing is mentioned.

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