v0.1.2Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It usefully discloses the shape of the result (four metadata fields per scene), which stands in for the absent output schema, but says nothing about volume, pagination, or permissions for a tool that returns 'every scene in the vault'.
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, zero waste, with the return fields front-loaded before the routing hint. Nothing could be cut without losing information.
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 zero-param discovery tool with no output schema, describing the returned fields is the essential missing piece and it is supplied. Only the behavior at scale (many scenes) and the read-only nature are left implicit.
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 is nothing for the description to disambiguate; the baseline for a parameterless tool 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 clear verb+resource (list scenes) and enumerates the returned fields (id, name, element count, last-edited time), which implicitly separates it from read_scene and describe_scene, which operate on a single scene. It stops short of naming those siblings explicitly.
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?
"Start here" implies this is the orientation/discovery entry point, but no when-to-use or when-not guidance is given, and no alternative is named (e.g. use read_scene once you have an id). Usage is only implied.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
