generate_controller_brief

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

Annotations (all false) convey no behavioral traits. The description adds 'Free' but does not disclose side effects, permissions, limitations, or what happens to session state. For a tool that produces a brief, it lacks detail on output format or potential impact.

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 sentence that is concise but lacks substantive detail. It is front-loaded with key points but could include more context without becoming verbose.

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?

With 5 parameters and no output schema, the description does not explain how parameters affect the output, the return format, or typical use cases. It mentions content of the brief (symptoms, actions, status, decision) but omits behavioral constraints.

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 100% (all parameters described in schema). The description adds no parameter-specific context beyond schema; therefore, baseline score of 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 clearly states that the tool generates a 'controller-ready reflective brief' containing symptoms, actions taken, current status, and next decision. It uses a specific verb ('generate') and resource ('controller brief'), distinguishing it from siblings like 'get_session_summary' or 'generate_fleet_summary'.

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, nor does it mention when not to use it. It only states what it does, leaving the agent to infer usage context.

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