v0.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds a meaningful caveat beyond the readOnlyHint annotation: 'Geometry measurements remain calculations, not verified business facts.' This warns the agent that measurement results are not authoritative, which is valuable. However, it does not elaborate on behaviors for each action (e.g., whether 'highlight' changes the UI selection state) or other side effects beyond the read-only annotation.
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 two sentences with no waste. The first sentence front-loads the core operations and target, and the second delivers an important caveat. Both sentences earn their place and the structure is clear.
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 tool with five distinct actions and an open-ended params object, the description is too sparse. It does not define what each action does, what parameters they expect, or what the return looks like (no output schema). It also does not clarify prerequisites like an active session or what 'managed work copy' means. The description is incomplete for an agent to call this tool correctly without further inference.
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 description coverage is 0%, and the description does not compensate. It lists verbs that roughly correspond to the action enum (e.g., 'inspect' vs 'get', 'highlight' vs 'select') but does not explain each action's purpose or the expected structure of the params object. The generic params is left entirely unexplained, and the wording mismatch between the description and enum values adds confusion.
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 clearly states the tool's purpose: to list, inspect, highlight, measure, or compare entities in the active managed AutoCAD work copy. The verb set is specific and distinguishes it from sibling tools like warehouse_cad_edit (modification) and warehouse_cad_export (export). The read-only nature is implied by the verbs and consistent with the annotation.
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 explicit guidance on when to use this tool versus the sibling tools. The description only mentions the active managed AutoCAD work copy, but does not explain when to choose query over edit/export/session/project. The name 'query' suggests a read-only role, but the description lacks any 'use this when...' or 'use X instead' guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
