artist_latest_releases

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

Annotations are absent, so the description carries the full burden, and it delivers: the quota disclosure ('🟡 one paginated /artists/{id}/albums walk') reveals pagination behavior, underlying API calls, and rate-limit cost, and 'age in days' explains the output computation. The verb 'Fetch' implies a non-destructive read, though it stops short of explicitly declaring read-only status or addressing empty-catalog/error cases.

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?

Two sentences with zero filler: the first fronts the purpose and key output detail, the second delivers the quota cost. Every phrase earns its place, and the structure makes the tool's intent legible at a glance.

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 filtered-list read with fully documented parameters, the description is nearly complete: it states purpose, output flavor (age in days), and rate-limit cost. Gaps are minor — no explicit safety framing (read-only) and no edge-case behavior — but with no annotations and no output schema, a touch more disclosure would make it fully self-sufficient.

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%, so the schema already documents all four parameters with defaults and enums. The description adds only tangential reinforcement ('most recent N' maps to limit, quota maps to the underlying albums walk) rather than new parameter-level meaning, which matches the baseline 3 for full 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 states a specific verb ('Fetch'), a well-defined resource ('the most recent N releases from an artist's catalog'), and a distinguishing output feature ('age in days'). The 'quick what's new here read' framing clarifies its intent, but it does not explicitly differentiate itself from closely related siblings like artist_latest_release_report, check_artist_releases, or artist_release_digest.

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 'quick what's new here read' phrase implies when to use the tool, and the quota note signals operational cost. However, it names no alternatives and gives no exclusion criteria or conditions for choosing a sibling tool, which is a real gap given the large number of overlapping artist-catalog tools in the toolset.

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