v0.1.4Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of disclosure. "Accept" implies a state mutation of an existing trade session, but the description says nothing about prerequisites, whether acceptance is reversible, what happens if no request is pending, or whether the trade window opens afterward.
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?
A single, front-loaded sentence with no filler or repetition. It is efficient, though its brevity reflects under-specification rather than true conciseness of content.
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?
For a state-machine action embedded in a multi-step trade workflow (request → accept → add item/zeny → lock → commit), the description omits the ordering, prerequisites, and outcome. With no annotations and no output schema, nothing else compensates for those gaps.
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 tool takes zero parameters, so there are no parameter semantics to document and the baseline of 4 applies. The empty schema is consistent with the description.
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 ("Accept") and resource ("incoming trade request"), which is clearly distinguishable from siblings like trade_request, trade_reject, and trade_cancel. However, it does not differentiate itself from trade_commit, which is the closest plausible alternative in the same workflow and could easily be confused with this one.
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 this tool is valid (e.g., a pending incoming request must exist, presumably created by trade_request) or how it relates to trade_commit/trade_lock later in the sequence. The agent must infer the trade workflow from sibling names alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
