playlist_set_details

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

With no annotations, the description carries the full behavioral burden. 'Update' implies mutation, but nothing is said about permissions required, reversibility, whether omitted fields are left untouched or cleared, or the effect of flipping the public flag. Significant gaps for a write tool.

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 front-loaded sentence with no padding; the slash-separated field list is compact. Slightly terse given how much remains unexplained, 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?

A mutation tool with no annotations, no output schema, 0% parameter coverage, and an overlapping sibling (playlist_rename) needs more than one sentence. Neither the ownership requirement nor the partial-update behavior is covered.

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%, so the description must compensate. It usefully enumerates the three mutable fields, but omits the required playlist_id and gives no semantics such as what boolean public values mean or string format expectations.

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?

Specific verb ('Update') plus resource ('a playlist') plus the fields it touches (name/description/public flag) makes the purpose immediately legible. It does not differentiate from the sibling playlist_rename, which plausibly overlaps on the name field.

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 playlist_rename, no prerequisites (e.g., must own the playlist or be a collaborator), and no statement about whether fields are patched or replaced. The agent must guess.

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