Publish the daylist

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

With no annotations provided, the description carries full burden and delivers: it discloses the multi-step side effects (replace, rename, set description, record run) and the first-use creation behavior. It also explains the purpose of recording the run (avoid future repeats), which goes beyond basic 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 extremely concise: two sentences, with the first enumerating all core actions and the second addressing first-use creation. Every word earns its place, and the structure front-loads the main purpose.

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 complex multi-step tool with no output schema and no annotations, the description is remarkably complete: it explains the atomic nature, the specific operations, the run recording, and first-time behavior. No critical gaps are evident for the intended use case.

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?

The schema covers two of three parameters with descriptions, and the tool description maps each parameter to its action (track_ids→tracks, title→new title, description→description). This adds meaningful context, especially for track_ids which lacks a schema description, supporting a score above the 3 baseline.

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 clearly states what the tool does: writes the daylist in one atomic step, replacing tracks, renaming, setting description, and recording the run. It uses a specific verb ('write') and resource ('daylist'), and distinguishes itself from generic create_playlist/update_playlist by describing the combined operation.

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 gives clear context for when to use this tool: when publishing the daylist as a single atomic operation. It does not explicitly contrast with sibling tools like update_playlist, but the specialized wording implies this is the dedicated tool for daylist commits, making the usage context clear.

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