playlist_place_pattern

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

With no annotations, the description carries the full burden of behavioral disclosure. It states the mutation ('Place') but does not disclose side effects such as overwriting existing clips, snapping behavior, track/pattern indexing, or what happens when length_bars is null. This is a meaningful gap for a modifying playlist operation.

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 a single sentence with no wasted words. The action, target, and key positional qualifier are all front-loaded, making it easy to parse at a glance.

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 mutation tool with no annotations, no output schema, and 0% schema description coverage, this description is too sparse. It omits behavior around the optional length_bars parameter and any side effects, leaving an agent without enough detail to anticipate the tool's full effect on the playlist.

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 for the schema's bare parameter names. The prose explains track, pattern, and position_bars in plain language, but it does not mention length_bars at all, leaving that optional parameter semantically undocumented.

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 uses a specific verb ('Place'), a specific resource ('pattern clip on a playlist track'), and a positional qualifier ('at a given bar position'). It clearly distinguishes this tool from playlist inspection tools like playlist_list_clips and playlist_delete_clip.

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 provides no guidance on when to use this tool versus alternatives, nor does it mention any exclusions or prerequisites. There are no sibling tools that perform the same action, so the usage context is only implied by the verb 'Place' rather than explicitly stated.

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