TDQS

A4.5/5.0
Behavior5/5

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

Beyond the annotations (readOnlyHint and openWorldHint), the description discloses payment requirements (USDC/USDT on Base via x402), the 3-free-calls-per-wallet allowance, and the restriction to public repositories. These are meaningful operational details an agent needs before invoking the 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?

Two dense sentences: the first captures the tool's output and scope, and the second covers payment and free-tier policy. Every clause earns its place, with no filler or repetition.

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?

The description is complete given the rich annotations and fully covered schema and output schema. It tells the agent what the tool returns, that only public repos work, how payment works, and the free-tier conditions. Nothing essential is missing for correct invocation.

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 description coverage is 100%, so the parameters are already fully documented. The description adds output-level detail such as 'language split (%)' and '5 most recent commits,' but does not need to explain individual parameters because the schema already covers them.

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 states a concrete action ('one-call overview') with a specific resource ('any public GitHub repository') and enumerates the exact data returned: description, stats, language split, license, README excerpt, and recent commits. This clearly differentiates it from broader Internet tools like web_crawl or web_search.

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 gives clear context: it is the right tool for pulling a single overview of a public GitHub repository, and it clarifies the public-repo scope. It does not explicitly name alternative tools or exclusion cases, but no near-sibling requires routing. It also adds cost/free-tier guidance with wallet-based calls.

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