album_focus_report

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

With no annotations supplied, the description carries the behavioral burden. It explicitly discloses the quota (1 GET /albums/{id} + 1 paginated discography walk), which tells the agent about resource usage and read-only GET semantics. It also reveals that the tool will walk the artist discography, which is important hidden behavior not otherwise visible from the schema.

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 compact and front-loaded: the first sentence establishes the tool's purpose and key output features, and the second sentence states the quota. Every clause adds substantive information without redundancy or filler.

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?

There is no output schema, so the description must convey what the tool returns; it does so by listing the report's contents (track listing, runtime, duration stats, edition detection, label/copyright). The quota and discography-walk behavior add important operational context. It could be slightly more explicit about the output format or edge cases, but it is largely complete for a read-only report tool.

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 parameters are already well documented. The description adds no additional parameter-level detail beyond the general 'one album' framing, which is already implied by album_id. This matches the baseline for a fully self-documenting schema.

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 is specific: it names the tool as a 'deep focus report on one album' and enumerates distinct deliverables (track-by-track listing, cumulative runtime, duration stats, edition detection, label/copyright capture). This uniquely positions it against sibling tools like get_album or album_track_stats by describing a composite analysis rather than a raw lookup.

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 phrase 'deep focus report on one album' implies when to use it, but there is no explicit guidance about when to prefer it over alternatives such as get_album, get_album_tracks, album_track_stats, or album_duration_report. No when-not-to-use or alternative-routing information is provided.

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