v0.3.5Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It states the action and target, but does not disclose side effects, idempotency, or behavior when the connection is already closed. This is acceptable for a very simple tool but lacks deeper context.
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, clear sentence that is front-loaded and free of any filler. Every word contributes to communicating the tool's purpose.
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 0-parameter, no-output-schema tool, this description is nearly complete. It clearly names the action and target, though it could benefit from a note about what happens if no connection is active or whether this aborts other operations.
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 has zero parameters, so the description need not add parameter-level detail. Baseline for 0 parameters is 4, and the empty schema and 100% vacuous coverage mean no information is missing.
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?
Uses specific verb 'Close' and resource 'serial connection to the FC', clearly identifying the action and target. This distinguishes it from sibling tools like 'connect' and 'find_fc' by describing exactly what is disconnected.
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?
No guidance on when to use this tool versus alternatives such as 'connect' or 'save_and_reboot'. The description states what it does but does not mention when it is appropriate to disconnect or any prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
