List qURL Sessions

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

Annotations already carry readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the bar is lowered. The description reinforces these and adds an interpretive detail: empty data[] means no active sessions. It does not elaborate on session expiration or auth requirements, but the annotations adequately cover the safety profile.

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?

Three tight sentences: primary action, usage alternatives, and a clear behavior note. Every sentence earns its place with no filler, and the most important information is front-loaded.

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 one-parameter read-only list tool with an output schema and comprehensive annotations, the description fully covers purpose, workflow, alternatives, and the meaning of an empty response. Nothing essential for correct invocation or selection is missing.

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 100%, with resource_id fully documented by type, pattern, and description. The description adds no parameter-specific detail, but none is required because the schema already carries the semantic load.

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 'List active access sessions for a qURL resource' – a specific verb and resource with a clear scope. It also distinguishes itself from siblings by clarifying that it shows live session state, not token/resource metadata (get_qurl) or session termination (terminate_qurl_sessions).

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?

Provides explicit when-to-use and when-not-to-use guidance: inspect sessions before rotating/revoking/terminating, use terminate_qurl_sessions when sessions should be ended, and use get_qurl when metadata is needed instead of active session state. This gives an agent concrete decision rules for tool selection.

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