decodificar_base64

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

No annotations are provided, so the description carries full burden. It discloses support for multiple Base64 formats (standard, URL-safe, padding variants), which adds behavioral context. However, it does not mention error behavior, output encoding, or whether the input must be a valid string, leaving gaps for an agent.

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 extremely concise: one line for purpose plus a brief parameter explanation. No redundant sentences, and the structure is front-loaded with the main action. Every sentence adds value.

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 tool's simplicity (one parameter, output schema exists), the description covers the core behavior and supported formats. It could mention that the output is the decoded string (implied by the tool name) and potentially the encoding, but the current version is largely complete.

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 0% description coverage, so the description must compensate. The 'Args' section explains that the parameter 'texto' is the Base64 text to decode, adding meaning beyond the schema's title 'Texto'. This is sufficient for a single-parameter tool.

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 it decodes Base64 text and specifies support for standard, URL-safe, and padding variants. The verb 'decodificar' and resource 'Base64' make the action unambiguous, and it naturally distinguishes from the sibling tool 'codificar_base64' (encode).

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 decoding Base64 text but does not explicitly state when to use this tool versus alternatives (e.g., 'codificar_base64' for encoding). No exclusions or prerequisite conditions are mentioned, leaving the agent to infer context from the sibling list.

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