xr18_snapshot_set_name

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

No annotations exist, so the description carries the burden of behavioral disclosure. It only states the action; it does not disclose whether the name is overwritten, persisted, or validated, nor what side effects occur on the device. The description adds little beyond what the tool name already implies.

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 very short and free of filler, with the action front-loaded. It is appropriately concise for a simple setter, though the phrasing is terse enough to create ambiguity.

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?

With no output schema and no annotations, a complete description should clarify that slot identifies a snapshot slot and that the name is being replaced on that snapshot. The current text is a minimal phrase that leaves the snapshot-slot relationship and mutation effects 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?

Schema description coverage is 0%, so the description must compensate for parameter meaning. 'Indexed' loosely maps to the slot parameter and 'name' to the name parameter, but it does not explain slot indexing semantics, slot bounds, or name constraints. This is only partial compensation for the missing schema documentation.

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 uses a specific verb ('Set') and a specific resource ('indexed snapshot name'), which distinguishes it from snapshot load/save/delete/scope operations. The phrase 'indexed' signals that snapshots are addressed by slot, but it is slightly vague and does not explicitly name the slot parameter.

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 guidance is given for when to use this tool versus alternatives like xr18_set or xr18_snapshot_set_scope. There is no mention of prerequisites, exclusions, or the context in which renaming a snapshot is appropriate.

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