youtube_rename_playlist

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

No annotations are provided, so the description carries the full behavioral burden. It implies a mutation and hints at an ownership/permission requirement via 'editable', but says nothing about OAuth needs, quota cost, whether the old name is recoverable, or what happens to a nonexistent/unowned playlist_id.

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?

A single short sentence with no filler, which is structurally clean. However, it is terse to the point of under-specification rather than being a model of concise completeness.

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 two-parameter mutation with no annotations and no output schema, the description omits which playlists qualify as editable, permission requirements, and error/return behavior. What an agent needs to invoke it confidently is largely missing.

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 0% and the description mentions no parameters at all, so neither playlist_id's format nor name's constraints (schema-only maxLength 150, minLength 1) are clarified in prose. Two required parameters remain semantically bare.

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 (Rename) and resource (playlist), so the action is unambiguous. It does not differentiate from siblings such as youtube_set_playlist_description or youtube_create_playlist beyond the verb itself, but the core purpose is clear.

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 qualifier 'editable' implicitly signals a precondition (you must have edit rights on the playlist), which is the only usage guidance offered. There is no explicit statement of when to use this versus alternatives like set_playlist_description, nor any exclusions or auth prerequisites.

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