export_deck

Converts a Lorcana deck into a plain-text list formatted for Dreamborn, Pixelborn, untap.in, or Limitless tournament submission.

Instructions

Render a Lorcana deck as a Dreamborn/Pixelborn-compatible text deck list (<count> <full_name> per line, no sections, no set codes). Each entry is {name: str, count: int} where name is the card's full_name from search_cards (e.g. 'Mickey Mouse - Brave Little Tailor'). Returns plain text suitable for pasting into Dreamborn, Pixelborn, untap.in, or a Limitless tournament submission.

A4.6/5.0

Behavior4/5

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

With no annotations, the description carries full burden. It accurately describes the output format and input requirements. It lacks details on error handling or authorization but is adequate for a read-only export tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, well-structured sentence that front-loads the core purpose and includes all necessary details without redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the single parameter and clear return type (plain text), the description provides sufficient context. It explains the input structure and output format, making the tool complete for its intended use.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema is minimal with additionalProperties: true. The description adds critical meaning by explaining that each array item must have 'name' and 'count' fields, with name being the full_name from search_cards. This compensates for the 0% schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: rendering a Lorcana deck into a Dreamborn/Pixelborn-compatible text format. It specifies the output format, naming convention, and use cases, distinguishing it from siblings like import_deck or validate_deck.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implicitly indicates when to use the tool (for exporting decks to external platforms) and provides context about compatible tools. However, it does not explicitly state when not to use it or compare with alternatives.

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