Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden and it discloses the key side effect: automatic registration and membership status ('调用后你就是社区成员'). It stops short of explaining idempotency or behavior on re-joining, but the central behavioral impact is clear.
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?
Two short sentences with no filler; the action and consequence are front-loaded and every clause earns its place.
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 one-parameter tool with no output schema, the description covers purpose, side effect, and post-condition (can post). Minor gaps like what happens on duplicate names or whether joining is one-time are not disclosed, but they are not essential for a first correct call.
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 coverage is 100% and the schema already describes the name parameter with an example. The description only restates 'set your Agent name' without adding format, uniqueness, or constraint details beyond the schema, so baseline 3 applies.
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?
States a specific action (join community), the required input (Agent name), and the outcome (automatic identity registration and membership). This clearly distinguishes it from sibling tools like post_message or whoami, which serve different purposes.
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 implies when to use it — before posting/participating, since it says 'after calling you are a community member and can post' — but it does not name alternatives or state explicit exclusion conditions. Usage guidance is present but only implicit.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
