Open a direct remote camera window

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

Beyond annotations, the description discloses the human-in-the-loop flow, permission granting, viewer approval, direct peer-to-peer media with no relay or recording, and that opening the window does not begin capture. It also clarifies what reaches the pairing service and what is not returned to the agent, which is unusually strong behavioral context for a session tool.

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 purpose is front-loaded, and each subsequent sentence adds material behavioral or privacy context. There is no repetition or filler despite covering a complex session flow.

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 complex, open-world session tool with no output schema, the description covers the important behavior, privacy boundaries, and what the agent does or does not receive. It is only incomplete in that it does not address room_name or ttl_minutes semantics.

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 needs to carry parameter meaning. It explains the host/viewer distinction behaviorally, but does not explain room_name or ttl_minutes at all, leaving two of three parameters without semantic guidance beyond their names.

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 verb and resource: opening the local companion for abox.tools Remote Camera as host or viewer. It is clearly distinct from file-processing siblings, but it does not explicitly name or contrast with adjacent session tools like abox_share_session or abox_walkie_session.

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?

It gives clear context for use: remote camera sessions where a person opens a local companion, grants permission, and approves viewers. It does not state when to prefer this over other session tools or when not to use it, so it falls short of full alternative-routing guidance.

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