Photos Detail

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: no read-only confirmation, no auth/session requirement despite host/port/profile parameters implying a connection context, no rate limits or side effects. The name"detail" weakly implies a read, which is all the agent gets.

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?

It is a single short sentence with no padding, so nothing needs trimming. But its brevity is under-specification rather than economy — the sentence earns its place only trivially and carries no differentiating 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?

An output schema exists, so return values need not be explained, and the parameter set is fully documented in the schema. What remains missing is the piece only the description can supply: how this read differs from the sibling photos tools, plus any session/profile prerequisite implied by the connection parameters.

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% — the schema already documents host, port, scheme, profile, and photo_id in Chinese. The description adds nothing beyond the required identifier, so no compensation is needed and the baseline of 3 applies.

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 sentence gives a verb+resource (获取照片详情) for a tool that requires a photo_id, so the basic intent is recoverable. However, "详情" is unspecified — it never says what detail is returned or how this differs from photos_preview_url, photos_search, or photos_folders, all of which touch the same photo domain.

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?

No when-to-use, when-not-to-use, or alternative is mentioned. An agent cannot tell from the description whether to call this or photos_preview_url / photos_search for a given photo-related need; usage must be inferred entirely from the tool name.

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