get_handoff

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

No annotations are provided, so the description must carry the behavioral burden. It mentions 'original saved merchant URL without rewriting it,' hinting at a read-only nature, but does not disclose any side effects, error conditions, or authentication requirements. It's too minimal for a tool with no annotations.

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?

The description is a single concise sentence, front-loaded with the core purpose. It avoids fluff, but is slightly under-specified; however, for conciseness it earns credit for being efficient.

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 the tool has an output schema and a single parameter, the description should at least explain what a 'handoff' is and what the 'original saved merchant URL' represents. It lacks context about when to use this tool, how it relates to capture_url, and what the output looks like. The description is inadequate for an agent to call it correctly in a broader workflow.

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?

The schema has 0% description coverage and the description doesn't explain what 'item_id' refers to. The agent is left to guess that it's an identifier for the handoff record, but no format, source, or relationship to the URL is provided. The description adds no value beyond the schema's bare property name.

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 states a specific verb ('Get') and resource ('original saved merchant URL'), and the phrase 'without rewriting it' implies a contrast with a rewriting variant, which helps distinguish it from tools like capture_url. However, it does not name the sibling tool explicitly, so it's clear but not fully differentiating.

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?

There is no guidance on when to use this tool versus alternatives. The description doesn't mention any context or conditions under which this tool should be chosen over siblings like capture_url or get_list, leaving the agent to infer usage.

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