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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description adds only the 'all playlists for a workspace' scope and says nothing about pagination, result ordering, or behavior when the workspace is empty — useful but thin beyond the structured hints.

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?

One short sentence, front-loaded with verb and scope, with no filler. It is slightly too terse to be maximally helpful, but nothing is wasted.

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?

An output schema exists so return values need not be explained, and annotations cover the safety profile, leaving the description only needing scope and usage context. It provides scope but omits when to choose it over sibling list/get tools and whether the optional collection_id means all workspaces.

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% and the single collection_id parameter is already documented as 'Workspace ID'. The description merely echoes the workspace scoping rather than adding format, default, or omission semantics, so baseline 3 applies.

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?

States a specific verb (get) and resource (all playlists) scoped to a workspace, so the agent knows exactly what it retrieves. It does not differentiate itself from neighbors like get_playlist_assets or create_playlist, but the read-all scope is self-evident.

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?

No guidance on when to use this versus alternatives such as get_playlist_assets (single playlist contents) or the paginated list_* family. No preconditions, no mention that collection_id is optional or what happens when it is omitted.

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