update_blist

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

Annotations already indicate destructiveHint=true, but the description adds no additional context about what gets updated, side effects, or prerequisites. The endpoint itself implies a mutation, but no behavioral specifics are disclosed beyond the annotations.

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 extremely short, but this is under-specification rather than effective conciseness. It consists of an endpoint and a note about SDK parity, with no substantive content that helps an agent understand the tool's function.

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 destructive mutation tool with 9 parameters and no output schema, this description is grossly incomplete. It doesn't cover what operation is performed, what parameters do, or what the response looks like, leaving the agent with almost no usable context.

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 only 11% (only dry_run has a description), and the tool description does not mention any of the 9 parameters. This creates a significant gap: neither the schema nor the description explains the meaning of parameters like name, active, webhook_url, or check_stop_list.

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 specifies 'POST /api/v2/blist/update' which indicates an update operation on a 'blist', but it doesn't explain what 'blist' means or what updating entails. The verb and resource are clear from the endpoint, yet the description reads more like a technical label than a functional explanation.

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 guidance on when to use this tool versus alternatives like create_blist or get_blist. The description only provides the endpoint and notes 'WhiteLabel (Python SDK parity)', which gives no context for selection.

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