Create phone remote

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

The description discloses critical behavioral traits beyond annotations: listens on all interfaces, accepts writes with no auth, and real-time live writes. This complements annotations (readOnlyHint=false, destructiveHint=false, openWorldHint=true) without contradiction.

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 concise with four sentences: purpose, behavior, security warning, pairing. Front-loaded with the main purpose, no wasted words.

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?

Given no output schema, the description covers purpose, mechanism, security, and companion tools. It is complete for an agent to understand what the tool does and how to use it safely.

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%, so baseline is 3. The description adds no explicit explanation of parameters, only implicitly through purpose. It does not enhance understanding beyond the schema.

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 clearly states the tool serves a mobile-friendly web panel to control numeric custom parameters from a phone, with specific verb 'Serve' and resource 'web panel'. It distinguishes itself from siblings by focusing on phone control and explicitly pairing with create_control_panel and manage_cue.

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 provides security context (use only on trusted network) and pairing guidance with complementary tools. However, it does not explicitly state scenarios when not to use the tool, but the security warning implies restrictions.

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