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

Annotations already declare destructiveHint=true, idempotentHint=false and readOnlyHint=false, so the safety profile is covered structurally. The description adds the admin-permission and approval-workflow context, which is genuinely new. It does not disclose whether the 'data' object is a merge/partial update or whether omitted fields are cleared — an important gap for a destructive, non-idempotent edit.

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 tight sentences with the editable-field list front-loaded and the permission/approval caveat second. No filler, though the approval sentence is a bit boilerplate-heavy relative to its informational value.

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?

An output schema exists, so return values need not be explained, and annotations carry the safety profile. Still missing for a destructive partial-update tool: whether unspecified fields are preserved, and how 'id' is interpreted. Adequate but with clear gaps.

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?

Top-level schema coverage is 0% (id and data are undocumented), though nested 'state' and 'market' carry detailed guidance. The description partially compensates by enumerating which fields under 'data' are editable and listing the status values, but it gives no meaning for 'id' or for the update semantics of the 'data' object.

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 ('Edit') and resource ('Target Location') and enumerates the mutable fields (market, state, priority, radiusMiles, notes, status), so the agent can separate it from create_target_location, delete_target_location and list_target_locations. It does not name a sibling explicitly, which keeps it a notch below a 5.

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?

'Organization admin required' plus the note about configurable MCP approval and mandatory business workflow approvals gives real prerequisite context. However, it never states when to prefer this tool over delete/update alternatives, nor what to do if the location doesn't exist.

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