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

With no annotations, the description must disclose behavior. It mentions cost and supported networks, and warns about premature calls. However, it lacks details on failure handling, idempotency, or side effects beyond the prerequisite.

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

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

Three sentences, front-loaded with cost, then action, then restrictions, then warning. No redundant information, every sentence adds value.

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

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

Given an output schema exists, the description need not detail returns. It covers prerequisites, parameters, and supported networks. Minor gap: no mention of error scenarios or expected output format, but overall adequate for moderate complexity.

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

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

Schema description coverage is 100%, baseline 3. The description adds context: tx_hash must be from completed transaction, package_tag identifies the package, and network must be one of the listed. This goes beyond schema definitions.

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

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

The description clearly states it verifies an on-chain crypto payment and delivers a JSON dataset CDN URL. It specifies supported networks and currencies, which distinguishes it from the sibling tool search_packages (likely for package lookup).

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

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

The description explicitly warns not to call the tool until a valid tx_hash exists, providing clear preconditions. It also lists supported networks. However, it does not mention when to use alternatives like search_packages.

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