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

With no annotations, the description carries the full behavioral burden. 'See' implies a read-only, non-mutating operation, and the enumeration of channel types suggests a complete listing, but it omits explicit read-only confirmation, auth requirements, pagination, and response structure.

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 front-loaded sentence with no wasted words. It efficiently communicates scope and examples without redundancy.

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 simple list tool, the description is incomplete: it does not document the required id parameter despite 0% schema coverage, provides no return format or pagination details, and has no annotations to compensate. The one-line description is inadequate for an agent to call it with full confidence.

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% for the single required 'id' parameter. The description only implies 'this agent' without naming or explaining the id parameter, leaving the agent to infer its meaning and format from the schema alone.

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 ('See'), resource ('every channel attached to this agent'), and enumerates channel types including widgets, telegram, phone, and presentations. This distinguishes it from siblings like list_agent_presentations and get_agent by explicitly covering all connections rather than a single category.

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 gives no when-to-use guidance, no alternatives, and no prerequisites. It only implies that one would use it to view channels, which is essentially a restatement of the purpose.

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