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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered structurally. The description adds genuinely new context that annotations cannot convey: the required los_proposed_targets:write scope. It stops short of noting any cascade effects on dependent targets.

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?

Two short sentences, zero filler, with the operation and its scope requirement front-loaded. Nothing could be removed without losing information.

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 single-parameter delete with full annotation coverage and no output schema, the description plus annotations give an agent everything needed to invoke it correctly. It is slightly thin on the consequences of deletion, which is the only real gap.

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 100% with a single well-documented uuid parameter, so baseline is 3. The phrase 'by ID' restates what the schema already provides without adding format or validation detail.

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?

States a specific verb (delete) and resource (LoS proposed target) plus the lookup key (by ID), so the operation is unambiguous. It does not explicitly contrast itself with siblings like delete_infrastructure_los_target or delete_system_los_target, but the resource name is precise enough to distinguish them.

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?

The description never says when to use this tool versus alternatives such as update_los_proposed_target (to modify) or the delete variants for other target types. No prerequisites, irreversibility caveats, or related-tool routing are given.

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