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

Annotations already state readOnlyHint, idempotentHint, and non-destructive behavior, so the safety profile is covered. The description adds no extra behavioral context such as pagination behavior, rate limits, or auth needs, and its claim of 'all assets' is potentially misleading because the schema exposes page_size and page_number parameters.

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 two short sentences, front-loads the core operation, and contains no filler. Every clause contributes to identifying the resource scope and the ordering option.

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?

Given full schema description coverage, safety annotations, and an output schema, the description is sufficient for a simple read-only list operation. The main missing contextual element is pagination behavior, which matters because page_size defaults to 10 despite the word 'all'.

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 five parameters, including sort_by, sort_order, page_size, and page_number. The description only restates that ordering can be chosen, adding no syntax, defaults, or meaning beyond the 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 states a specific verb and resource: get/list assets that are inside a playlist. The phrase 'inside playlist' clearly distinguishes it from siblings like list_assets, get_all_playlists, add_asset_playlist, and remove_asset_playlist.

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 says what the tool does but gives no guidance on when to use it versus alternatives such as list_assets or get_all_playlists. There are no prerequisites, exclusions, or sibling-tool routing cues.

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