TDQS

A3.8/5.0
Behavior3/5

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

With no annotations provided, the description must convey behavioral traits. It indicates a read operation retrieving 'recent' activity but does not define how recent, whether results are cached, pagination behavior, or rate limits. While not misleading, it omits helpful context beyond the schema.

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?

A single 20-word sentence that packs all essential information: resource, action, scope, and data included. No unnecessary words or repetition. Perfectly concise.

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

Completeness4/5

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

For a simple tool with 2 parameters and no output schema, the description provides sufficient context about the resource and output. It lacks details on ordering or time range, but given the straightforward nature, it is largely complete.

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% with both parameters described. The description adds meaning by explaining the output includes bids, listings, sales with prices, buyers, sellers, and timestamps, which is not in the schema. This helps the agent understand what the response will contain.

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 retrieves recent activity for a Magic Eden Solana NFT collection, explicitly listing event types (bids, listings, sales) and included data (prices, buyers, sellers, timestamps). This distinguishes it from siblings like nft_listings or nft_stats, which focus on different aspects.

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

Usage Guidelines2/5

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

The description lacks any guidance on when to use this tool versus alternatives. It does not mention exclusions, prerequisites, or scenarios where other tools (e.g., nft_floor for floor price, wallet_activity for wallet-specific data) would be more appropriate.

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