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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so safety is covered. The description still adds useful context: what the status reports, the overall recording pipeline, and importantly that 'the user approves in Arsaze before anything is opened' — a meaningful gating detail not in 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 paragraph is reasonably sized but poorly front-loaded: it opens with a rhetorical question rather than the tool's function, and it spends significant space narrating the entire recording workflow, which is arguably out of scope for a status-check tool.

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 read-only status tool with no output schema and three optional pagination/format parameters, the description supplies return-value semantics, parameter meanings, and workflow position. Nothing essential is missing, though pagination limits are left to server instructions.

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%, so the description must carry the load, and it does: 'response_detail (summary|compact|full), fields (dotted paths), cursor (next page).' It documents all three optional parameters, though the enum values for response_detail are only implied and it defers the rest to server instructions.

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 function: reporting whether the Arsaze desktop app is connected, its platform, and whether it can drive native apps versus only web pages. It is distinguishable from siblings like screen_open or screen_look. However, the actual purpose is buried mid-sentence behind a rhetorical question, slightly weakening immediate clarity.

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?

Explicitly says 'Call first,' establishing this as the entry point before any screen action. It also routes among alternatives (screen_open vs. screen_list_apps + screen_open_app) within the described flow. No explicit when-not-to-use, but the ordering guidance is concrete.

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