gallery_import_stills

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

No annotations are provided, so the description carries the full burden. It only states the action 'import' but does not disclose behaviors such as whether existing stills are overwritten, how invalid file paths are handled, whether the album is auto-created, or any permissions/errors. This is a significant gap for a tool that modifies gallery state.

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 a single concise sentence that directly states the tool's function without any filler or redundancy. It is appropriately sized for the tool's simplicity and front-loads the key action and target.

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 low complexity (2 params, no nested objects) and the presence of an output schema plus full param documentation, the description is minimally adequate. However, it lacks contextual details like whether the album must already exist, supported file formats (though examples are in the schema), and error behavior. This leaves some gaps for a new user.

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 input schema already covers 100% of parameters with descriptions for both album_name and file_paths. The description text adds no additional parameter meaning, so it meets the baseline for high schema coverage.

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 uses a specific verb ('Import') and resource ('still image files' into 'a Gallery album'), clearly distinguishing it from sibling tools like gallery_grab_still (capture) and gallery_export_stills (export). No ambiguity remains about the core operation.

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 explicit guidance on when to use this tool versus alternatives. It does not mention that gallery_grab_still is for capturing from the current frame, nor does it state any prerequisites (e.g., album must exist). The only usage hint is embedded in the album_name schema description about defaulting to the current album, which is not in the main description.

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