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

Annotations already mark the tool as readOnly and non-destructive, and the description adds useful behavioral context: it explicitly states that human seen positions are not advanced and nothing is modified. The ordering guarantee is also disclosed. No contradiction with annotations exists.

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 two short sentences with no filler. The core action and ordering are front-loaded, and the non-modification guarantee directly follows. Every sentence adds value.

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?

The tool is simple, annotations cover safety, and the purpose is clear. However, there is no output schema, no parameter explanations, and no guidance on pagination behavior or when to choose a sibling tool. The description is minimally adequate but leaves meaningful gaps for correct invocation at scale.

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% and the description does not explain the 'limit' or 'after_id' parameters. The phrase 'ordered by UUID' weakly implies that after_id is a cursor, but the agent is left without explicit pagination semantics, defaults, or how the parameters interact.

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 uses a specific verb and resource: 'Read your current List directory', and adds an ordering detail ('ordered by UUID') plus an explicit non-modification guarantee. This distinguishes it from siblings like get_list and query_list_activity.

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 states what the tool does but gives no explicit guidance on when to use it versus alternatives such as get_list or list_live_views. No exclusions, prerequisites, or selection criteria are provided, so an agent must infer usage from the name and purpose alone.

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