Update Subnetwork

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=true, and openWorldHint=false. The description adds the behavioral detail that whole-tier updates are gated behind a confirmation phrase, which is useful safety context not in the annotations. It still omits what the update actually changes, auth requirements, and side effects. There is mild tension with destructiveHint=false, but it is not a direct contradiction.

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 one tight sentence with no wasted words and front-loads the core operation. It is appropriately concise, though for an 11-parameter tool it may be too sparse to be fully useful.

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 complex utility-network update tool with 11 parameters and no schema descriptions, the description is far from complete. An output schema exists, so return values need not be explained, and annotations cover the safety profile, but the agent still lacks guidance on most parameter semantics and the exact confirmation-phrase mechanism.

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% for 11 parameters, so the description must carry the burden. It hints at scope (single subnetwork vs entire tier) and therefore touches on tier, all_subnetworks, and subnetwork_name, but it does not explain required parameters such as expected_network, source_kind, or source_identifier, nor the confirm_all phrase. This leaves most parameters semantically opaque.

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 states a specific verb (update) and resource (subnetwork), and scopes the operation to a single subnetwork or an entire tier. It does not explicitly differentiate from siblings such as arcgis_pro_export_subnetwork or arcgis_pro_utility_network_trace, but the core purpose is unambiguous.

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?

It implies usage context by noting that whole-tier operations require a destructive gate and a fixed confirmation phrase, which tells the agent a prerequisite exists for that mode. However, it gives no guidance on when to prefer this tool over alternatives like export_subnetwork or network_trace, nor any exclusions.

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