A4.3/5.0

Behavior4/5

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

Annotations already indicate read-only and idempotent. Description adds that it returns only the lowest-price active offer and compares across all partners, providing useful context beyond annotations.

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 concise sentences with no wasted words. The first sentence delivers the core purpose; the second adds a distinguishing USP.

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?

Complete for a simple lookup tool with full annotations and output schema. Description clearly explains scope and uniqueness.

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

Parameters3/5

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

Schema coverage is 100% with parameter descriptions. Description does not add semantic details beyond the schema, meeting the baseline.

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?

Clearly states it finds the lowest-price active offer for an audiobook across all affiliate partners. The USP differentiates it from siblings like compare_all_offers.

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?

Implies use when cheapest offer is desired, but does not explicitly mention when to use alternatives like compare_all_offers for all offers.

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

A4.4/5.0

Disambiguation5/5

Each tool has a clearly distinct purpose. Overlapping functions like price comparison are differentiated by granularity (full table vs. cheapest), and search tools are separated by query style (free-form vs. filters).

Naming Consistency5/5

All tool names follow a consistent verb_noun pattern with lowercase underscores (e.g., get_audiobook, search_audiobooks, list_partners). The verbs (browse, compare, find, get, list, search) are appropriate and consistently applied.

Tool Count5/5

With 13 tools, the set is well-scoped for an audiobook catalog and price comparison service. It covers discovery, search, detail retrieval, price analysis, and market statistics without being overwhelming.

Completeness4/5

The tool surface covers core operations: search, browsing genres, detailed profiles for audiobooks/authors/narrators/publishers, price comparison and trends, rankings, and partner listings. Minor gaps exist, such as no tool for listing all audiobooks without a search query, but the coverage is still very strong.
