  4. First observed

TDQS

A4.5/5.0
Behavior4/5

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

Annotations already declare readOnly, idempotent, openWorld, and non-destructive. The description adds useful context beyond them: it returns both upright and reversed meanings plus keywords and image description, which tells the agent what the payload contains. Lacking only error behavior for unknown ids.

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?

Two tightly packed sentences with no waste: purpose and accepted keys first, then return contents. Front-loaded and readable.

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?

For a one-param lookup tool with full schema coverage, annotations, and an output schema, the description covers purpose, key formats, and return shape. Nothing an agent needs to call it correctly is missing.

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

Parameters4/5

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

Schema coverage is 100%, so the schema documents name_short fully. The description adds value by giving examples of both accepted key forms (id like "major_00" and exact name like "The Fool"), reinforcing the dual-mode parameter beyond the schema text.

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?

States a specific verb (looks up), resource (one card from the Pipeworx tarot deck), and lookup keys with concrete id/name examples. It clearly distinguishes itself from search_cards, random_card, and draw_cards by being a single-card exact lookup.

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 makes clear this is for fetching exactly one known card by id or exact name. It does not explicitly name siblings like search_cards as the alternative when the key is unknown or partial, but the 'exact name' constraint implies the boundary reasonably well.

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