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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safe-read nature is covered structurally. The description adds nothing beyond that — no mention that it performs a live lookup by id or what breadth of data a release detail includes. No contradiction with annotations.

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?

It is a single terse sentence with zero waste, but the terseness reflects under-specification rather than disciplined editing — nothing is front-loaded because there is nothing to front-load.

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 tool is simple (one param) and an output schema exists, so return values need no explanation. Still, the description leaves the agent without any contextual signal about what a release detail contains or how it differs from master/label lookups, which is a modest but real gap.

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?

Single required parameter 'id' is fully described in the schema with a concrete example (249504), so the schema carries the semantics. The description adds no syntax or format guidance, which puts it at the baseline for high-coverage schemas.

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?

"Discogs release detail" names the resource (release) and implies a retrieve-detail operation, which loosely differentiates it from discogs_artist, discogs_label, and discogs_master. However, it's a noun phrase with no verb and could be confused with the release-oriented outputs of discogs_artist_releases or discogs_label_releases.

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?

There is no when-to-use guidance. Nothing tells the agent this fetches a single release by id versus using discogs_search to find one first, nor when a release rather than a master is the right target.

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