engagement_end

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

With no annotations, the description carries the full burden. It does disclose a side effect ('clear scope restrictions'), but it does not state whether closing is irreversible, requires permissions, or impacts existing findings or job runs. The main verb 'Close' is largely redundant with the tool name.

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, concise sentence with no filler words. It front-loads the action and immediately states the key side effect, making it highly efficient.

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?

Given the simple zero-parameter, no-output-schema nature, the description is minimally adequate. However, it does not mention whether an active engagement is required, whether the action is reversible, or what happens after closing, leaving some operational ambiguity.

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?

The tool has zero parameters, and the schema is empty. Per the rubric, a baseline of 4 applies since there is no demand for parameter explanation. The description adds no parameter-level detail, but none is needed.

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 uses an active verb ('Close') with a clear resource ('the current engagement') and adds a specific effect ('clear scope restrictions'). It clearly distinguishes this tool from siblings like engagement_status or engagement_start by indicating the termination action.

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 provides no guidance on when to use this tool versus alternatives, such as program_scope_end or engagement_status. It does not mention prerequisites like an active engagement or that it should be used at the end of a session.

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