artist_album_timeline

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 does disclose that this is '[local-compute]' and entails 'one paginated /artists/{id}/albums walk,' which informs the agent about the underlying operation and quota usage. However, it does not specify the output shape beyond a 'table,' nor clarify side effects (though read-only is implied). This is partial but not comprehensive transparency.

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, dense sentence that front-loads the core purpose (chronological table with gap stats) and includes a quota qualifier. There is zero waste, and the key details are immediately visible.

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 moderately complex tool with 4 parameters and no output schema, the description offers some context (local-compute, quota) but lacks details on calculation semantics (e.g., how 'drought' is defined, whether all album groups are included by default) and edge cases. The response_format param covers output variance, but overall completeness is adequate but incomplete.

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 75%, but the max_results parameter has no description in the schema, and the tool description does not clarify it. The description adds no parameter-specific meaning; it only describes the overall output. With moderate coverage and no compensation from description, parameter semantics are weak.

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 specifies a clear deliverable: a chronological release table with inter-release gap days, median gap, and longest drought highlighted. It names the underlying resource (/artists/{id}/albums), so an agent knows what data is involved. However, it does not explicitly differentiate itself from similar sibling tools like artist_discography_timeline or artist_singles_timeline, which limits clarity about its unique role.

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 provides no guidance on when to use this tool vs alternatives. With many timeline/discography siblings (artist_discography_timeline, artist_singles_timeline, get_artist_albums, etc.), the agent must guess when this tool is appropriate. The quota note is operational, not usage guidance.

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