v1.12.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The readOnlyHint annotation already establishes that this is a safe read operation. The description adds useful behavioral context by stating that it checks for a published update and explains how to update, which goes beyond the annotation. It does not mention authentication or rate limits, but those are minor for a zero-parameter version-check tool.
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, front-loaded sentence that covers the tool's three behaviors without any redundant or filler text. 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 simple zero-parameter, read-only tool with no output schema, the description fully communicates what the tool does and what information it returns (installed version, update availability, update instructions). Nothing essential is missing.
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?
There are no input parameters, so the empty schema is complete and the description does not need to explain parameter semantics. The baseline for zero parameters is 4.
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 and resource: it shows the installed connector version, checks for a published update, and explains how to update. This is clear and distinct from most siblings, though it does not explicitly differentiate itself from update-related sibling tools such as ml_actualizar_publicacion.
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 the tool is useful (when the user needs version or update information), but it does not explicitly state when to use it versus alternatives or provide any exclusions. Usage context is left to inference.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
