download_edition_by_date

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

With no annotations, the description carries the full burden. It discloses that it downloads a PDF, returns metadata plus file path and size, and raises an error if no edition exists. It does not detail output_dir behavior (defers to another tool) or side effects like overwriting, but is adequate for a simple download.

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?

Three concise sentences plus clean argument descriptions. No fluff, front-loaded purpose, and easy to parse. 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?

Covers tool purpose, parameter semantics, error handling, and return values. Lacks explicit details on output_dir default behavior and exact return structure, but references another tool for more info. Adequate for a simple two-parameter tool without output schema.

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%, so description must compensate. It explains 'date' format with example ('dd/MM/yyyy') and 'output_dir' purpose (directory to save PDF). It adds semantic value beyond schema types, though output_dir details are deferred.

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 clearly states 'Download the Diario Oficial edition published on a specific date' with a specific verb and resource. It distinguishes from siblings like download_edition_by_number and download_latest_edition by emphasizing the date-based selection.

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?

Provides clear context for when to use (by date) and mentions error condition ('Raises if no edition was published'). However, it does not explicitly advise against using it for other criteria or list alternatives, though sibling tool names imply them.

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