workload_assistant_warm

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

Annotations already declare readOnlyHint=true, but the description adds meaningful behavioral context beyond them: '(no model call)' tells the agent this is a pure warm-up that returns no answer and incurs no model cost. It still doesn't describe the return value or whether repeated calls are idempotent.

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?

A single tight sentence with the action front-loaded and the qualifier '(no model call)' appended compactly. Zero wasted words, appropriate for a simple warm-up tool.

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 low-complexity warm-up tool with no output schema and read-only annotations, the description is mostly sufficient. However, the undocumented 'profile' parameter and the absence of any note on what the call returns (or a status signal) leave a small but real gap.

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 0%, so the description must carry parameter meaning, yet it mentions neither chat_id nor profile. chat_id is self-evident, but the optional 'profile' parameter is left entirely unexplained in both the schema and the description.

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+resource: 'Start the Workload chat's assistant process.' The 'Workload chat' qualifier distinguishes it in scope from the many sibling *_assistant_warm tools (sql_editor, notebook, query_history), though it doesn't name them explicitly. The purpose is unambiguously a pre-warm 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 phrase 'ahead of the first question' implies when to call it (before the first user question) but never states that workload_ask is the actual answering tool or gives explicit when-not guidance. Usage is implied rather than spelled out.

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