create_click_track

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

Annotations only declare destructiveHint=false, so the description carries most of the burden. It usefully explains that the track hosts REAPER's click source, follows the tempo map and time-signature changes, and accents downbeats, but says nothing about whether repeated calls create duplicate click tracks or how the project state is affected.

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?

Front-loaded single-sentence purpose followed by compact Args and Returns blocks; nothing is wasted and the ordering matches how an agent reads it.

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?

No output schema exists, but the description lists the return fields (track_index, item_index, start, end) and covers all parameters. Only the lack of mutation side-effect information keeps it from being fully complete for a create operation.

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 coverage is 0%, and the description does compensate by documenting all three args, including the key default that end falls back to the project end. However, the defaults for start (0) and name ('Click') are not mentioned, and units for start/end are only given as 'seconds'.

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 + resource ('Add a click track') plus a placement constraint ('at the end of the track list') that separates it from generic insert_track. It never names the sibling alternative explicitly, but the scope is unambiguous.

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?

Usage is only implied: the agent must infer that this is for creating a tempo-following metronome track rather than a normal track (insert_track) or an item. No when-to-use/when-not guidance or prerequisites are stated.

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