Clone Update Set

clone_update_set

Clone a ServiceNow update set by creating a new update set with a specified name and copying all records from the source. The new update set starts in 'in progress' state.

Instructions

Clone an existing update set by creating a new one and copying all its records. The new update set gets the specified name and starts in 'in progress' state.

IMPORTANT: This creates a new update set and copies all records on the instance.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
instanceNoThe ServiceNow instance auth alias to connect to. This is the alias configured via `snc configure` (e.g., "myinstance", "prod", "test"). The user will typically refer to this by name when saying things like "on my myinstance instance". If not provided, falls back to the SN_AUTH_ALIAS environment variable.
source_sys_idYesThe sys_id of the update set to clone.
new_nameYesThe name for the new cloned update set.
Behavior3/5

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

No annotations are provided, so the description must carry the full burden. It discloses that the tool creates a new update set in 'in progress' state and copies all records, but does not mention permissions, side effects, or reversibility. Adequate but not comprehensive.

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

Conciseness5/5

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

The description is two sentences plus a brief important note, all front-loaded and to the point. No extraneous words.

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?

Given the simple nature of the tool (clone with 3 parameters, no output schema), the description adequately explains the operation and its result. It lacks some behavioral details but is sufficient for an agent to understand the tool's function.

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%, so baseline is 3. The description adds context that the new name determines the state ('in progress'), slightly enhancing understanding beyond the schema, but not enough to raise the score.

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

Purpose5/5

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

The description clearly states the verb 'Clone' and resource 'update set', distinguishing it from siblings like 'create_update_set' and 'inspect_update_set'. The action and result are precisely described.

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

Usage Guidelines2/5

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

No guidance is provided on when to use this tool versus alternatives (e.g., creating a new update set or importing records). The description only states what it does, not when it's appropriate.

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