codificar_base64

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

Despite no annotations, description explains the two encoding variants and their effects (character replacements and padding removal). However, it does not mention return type, error handling, or behavior with non-ASCII text, which are relevant for a text encoding 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: a one-sentence summary followed by a clean Args list. Every sentence is necessary and no redundant information.

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 low complexity and presence of output schema, description covers key aspects. However, it could mention that it encodes text (not binary) and that the output is a string, but the output schema likely fills that gap. Minor completeness gap for non-ASCII text handling.

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?

With 0% schema coverage, description fully defines both parameters: 'texto' as the text to encode and 'url_safe' as the option to use URL-safe variant with specific character changes. This adds significant value beyond the schema's type-only definitions.

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?

Description uses specific verb 'codifica' and resource 'texto', and clearly distinguishes between standard and URL-safe Base64 variants. This differentiates it from sibling tool decodificar_base64 and others.

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?

Implies usage for encoding text to Base64, but lacks explicit guidance on when to choose URL-safe vs standard, or when not to use it (e.g., for binary data). No mention of alternatives beyond the listed sibling tools.

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