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

Annotations already declare destructiveHint=false and openWorldHint=false, so the description does not need to restate safety. The description adds that the outcome can be undone, which is useful behavioral context, but it does not explain whether an existing outcome is overwritten, what permissions are required, or what happens after the activity is no longer in a wrap-up state.

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 a single front-loaded sentence with no filler. The parenthetical efficiently signals the undo variant without adding clutter.

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 simple mutation tool with full schema coverage and basic annotations, the description covers the core action and undo. It still leaves important context unstated, such as whether the activity must be in a specific wrap-up state, whether outcomes can be replaced, and whether undo restores a previous outcome or simply clears it.

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%, so the schema already explains activity_id, outcome, undo, and purpose. The description adds only the general notion that outcome and undo are related, without adding format, constraints, or examples beyond the schema.

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 and resource: setting an outcome on a call wrap-up activity, and notes it can be undone. It is clear enough to distinguish from generic activity tools, but it does not explicitly contrast with the related desk_wrap_call or desk_get_activity siblings.

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?

There is no explicit when-to-use guidance or named alternative. The phrase '(or undoes it)' only describes the undo capability, not the conditions under which an agent should set versus undo an outcome or use a wrapping tool instead.

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