v0.2.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden, yet it discloses nothing beyond the bare action. It does not state ordering, scope (all projects vs. current), pagination, or what fields each drawing entry carries. For a read-only list the risk is low, but almost no behavioral context is added.
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 three-word sentence with zero padding, and the core action is front-loaded. It is perhaps under-specified rather than over-long, but there is no wasted text.
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?
No output schema and no annotations exist, so the description is the only source of information, yet it says nothing about the shape or scope of the returned list. Minimum viable for a trivial list tool, but it leaves the agent guessing about return contents.
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 the baseline of 4 applies; there is no parameter semantics to clarify and the description neither misleads nor omits anything parameter-related.
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 verb ('List') and resource ('saved drawings'), so the agent knows exactly what it retrieves. It does not, however, distinguish itself from siblings like drawing_info, drawing_layers, or scan_list, which all deal with stored drawing data.
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 when-to-use guidance, no mention of prerequisites, and no indication of which sibling to pick when the agent needs entities, layers, or a single drawing's metadata. Usage is only inferable from the name.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
