List Displays

list_displays

Read-onlyIdempotent

Lists all displays the user can access, with id, name, online status, lock state and device class — the starting point to discover display IDs before get_display, send_html or send_store_template_to_display. Pass org_id to list an organization's displays instead. response_format 'detailed' adds screen/viewport facts, URLs and language per display. To show what a display looks like right now, use get_display_preview_url. Requires content scope.

TDQS

A4.3/5.0

Behavior4/5

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

Annotations indicate read-only, non-destructive, idempotent. Description adds context on scope (user's displays), output fields, and requirement (content scope), enhancing transparency beyond annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two clear sentences; front-loaded with purpose, then logically flows to options and alternatives. No redundant information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Covers output fields, prerequisites, and related tools. For a listing tool with output schema and good annotations, this is complete and sufficient.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema covers all parameters with descriptions. Description adds no new parameter details beyond reaffirming org_id use and response_format behavior, so baseline score applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states the tool lists all accessible displays with specific fields, and positions it as the starting point for display-specific tools, distinguishing it from siblings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides when to use (before get_display etc.), how to use org_id and response_format, and points to an alternative (get_display_preview_url). Lacks explicit when-not-to-use, but sufficient for a listing tool.

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