update_album

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

With no annotations, the description carries full burden. It clarifies that empty string values for name and description mean no change, which is useful. However, it does not disclose error handling, idempotency, permissions, or side effects beyond mutation.

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 extremely concise: a single sentence stating the purpose followed by a bullet-style argument list. Every word earns its place, and the most important information is front-loaded.

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?

The description is adequate for a simple update operation but lacks information about return values (output schema exists but not mentioned), error conditions, and prerequisites (e.g., album must exist). It does not discuss when to use this tool versus other update tools like update_asset_metadata.

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?

Description adds meaning beyond the input schema by explaining the semantics of empty strings for name and description ('empty = don't change'). The schema only provides defaults and types; the description clarifies the behavioral meaning. This compensates for the schema's lack of descriptions (0% 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 clearly states the action 'Update an album's name or description' with a specific verb and resource. It distinguishes from sibling tools like create_album, delete_album, and get_album by focusing on modification of existing album properties.

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?

The description does not provide any guidance on when to use this tool versus alternatives. It does not mention exclusions, prerequisites, or suggest other tools for different update scenarios (e.g., updating assets or shared links).

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