Remove cursor enhance

remove_cursor_enhance
Idempotent

Removes pointer enhancement and restores the original cursor appearance from the untouched source.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

TDQS

A3.5/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false, so the safety profile is supplied structurally. The description adds the useful detail that the original is recovered from an 'untouched source,' which corroborates the non-destructive, reversible nature of the operation, but it says nothing about failure behavior or scope of the removal.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One sentence, front-loaded with the action and followed immediately by the resulting state; no filler. The trailing phrase 'from the untouched source' is slightly abstract but not wasteful.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a one-parameter, non-destructive removal tool with full annotation coverage and no output schema, the description covers the action and the post-condition. Missing only the no-op/not-applied edge case, which is a minor gap at this complexity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the single project_id parameter is already well documented, including the caveat that the navigation pointer does not select the target. The description adds no further meaning about project_id, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and object ('Removes pointer enhancement') plus the outcome ('restores the original cursor appearance'), which is enough for an agent to distinguish it from the add_* siblings. It does not explicitly name its inverse, enhance_cursor, so sibling differentiation is implied rather than stated.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is only implied: the phrase 'restores the original cursor appearance' hints that this undoes a prior enhancement, but the description never says when to call it, whether enhance_cursor must have been applied first, or what happens if no enhancement exists on the target.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
