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

No annotations are provided, so the description carries the full burden. 'Gracefully' is a useful behavioral signal, but the description does not say what stopping entails (drain, shutdown delay, reversibility), whether it requires permissions, or how it differs operationally from the forced kill_app.

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?

One front-loaded sentence with no filler. The key distinguishing qualifier 'gracefully' appears immediately and nothing is wasted.

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 mutation tool with no annotations, no output schema, and an undocumented required parameter, the description omits the operationally important details: whether the stop is reversible, what a subsequent action should be, and how it relates to kill_app.

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 single required parameter managed_app_id has 0% schema description coverage, and the description only indirectly characterizes the target as a 'running managed application'. The parameter's identity is self-evident from its name, so this is adequate but adds little 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 ('stop a running managed application'), and the qualifier 'gracefully' hints at how it differs from the destructive sibling kill_app. However, it never names that sibling, so differentiation is left to inference.

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 statement of when to use this versus kill_app, start_app, or check_app_status, nor any precondition such as the app needing to be running. The agent must infer that 'gracefully' is the selection criterion.

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