activate_camera

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

With no annotations, the description carries the full behavioral burden and does disclose the single most important fact: this is a safety-gated stub, not a working control path. It stops short of describing the runtime behavior on invocation (exception vs. silent no-op) or any gating/permission mechanics implied by 'safety-gated'.

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?

A single short sentence with no filler, front-loading the two facts that matter (safety gate, unimplemented). It is efficient, though it is terse to the point of omitting information an agent would still need if it ignored the warning.

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 placeholder tool, the description covers the essential 'do not rely on this' message, but it leaves unclear what a call actually does and what camera_id refers to, and there is no output schema to fill those gaps.

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 sole required parameter camera_id has 0% schema description coverage, and the description adds nothing about its meaning, format, or source (e.g., from list_camera_tools). With one undocumented parameter, the description should compensate and does not.

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 does not state what the tool would do functionally beyond the name 'activate_camera'; its only content is a status disclosure that camera control is not implemented. That disclosure usefully distinguishes it from functional siblings like set_pp_filter or capture_replay_shot, but the actual intended operation is left to the name alone.

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?

Saying 'not yet implemented' effectively signals when not to call it, which is meaningful guidance. However, it names no alternative sibling to use instead for camera-related work, and does not say whether the tool errors, no-ops, or partially executes if invoked.

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