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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered. The description adds genuinely new behavior: run_now is asynchronous and its answer surfaces later via cotlet_automation_list, plus a confirmation requirement before delete. It does not describe what pause/resume return or whether they are reversible, which keeps it below a 5.

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?

Extremely compact with no wasted words, and the destructive-action warning is placed at the end where it is noticed. The telegraphic fragment style ('pause, resume, run_now ... or delete') is slightly harder to parse than a full sentence but is 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?

For a two-parameter action tool with no output schema, the description covers the key gap an agent would hit: that run_now does not return its result inline. Combined with the delete-confirmation rule and the annotations, an agent has enough to invoke it correctly; only the return behavior of pause/resume/delete is unstated.

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 coverage is 50%: the action enum is fully self-documenting and the automation parameter already points to cotlet_automation_list. The description adds only the async semantics of run_now, which is useful but does not deepen understanding of the parameters themselves. Baseline 3 is appropriate.

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 enumerates the four concrete operations (pause, resume, run_now, delete) on an automation, which is a specific verb+resource statement. It is a fragment rather than a full sentence and relies on the tool name/title to establish the resource, but an agent can still tell it apart from cotlet_automation_save or cotlet_automation_test.

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?

It gives a clear conditional instruction ('Ask the user before delete') and routes the agent to cotlet_automation_list for the run_now result, which is real when-to-use guidance. It does not state when to prefer pause vs. delete or any prerequisites, so it stops short of full alternative coverage.

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