get_camera_info

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

Discloses that it returns full details without fetching a snapshot, a key behavioral trait. No annotations exist, so the description carries the full burden; it adequately covers the safety profile for a read-only lookup.

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?

Two sentences, no wasted words; each sentence provides essential information.

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 the single parameter, lack of output schema, and no annotations, the description is fully adequate—it explains what the tool does, when to use it, and what it returns.

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?

The schema already describes 'cam_id' well (100% coverage), but the description adds context about using it to validate an ID or get metadata, enhancing parameter meaning.

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 it looks up camera metadata by ID, returning full details for a single camera without a snapshot, distinguishing it from siblings like get_snapshot and list_cameras.

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 'Use this to check if an ID is valid or to get current metadata for a known camera,' providing clear context. However, it does not mention when not to use it or exhaustively list alternatives.

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