Publish players

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

With no annotations, the description carries the full burden and does so excellently. It explains batch behavior (omit player_id publishes all), per-player failure handling (returns in 'failed' without aborting), the 'skipped' category with a reason, snapshot durability, and the heartbeat/timing aspect. This is comprehensive behavioral disclosure.

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 well-organized with clear sections and uses bullet points for readability. Every sentence adds meaningful information with no fluff. The length is appropriate for the tool's complexity.

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?

The description covers the operation's trigger, the batch-wide scope, return behavior ('failed', 'skipped' with reasons), durability, and the 10-second heartbeat expectation. Even without an output schema, this gives the agent enough context to invoke the tool correctly and interpret results.

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 100% and the schema already documents player_id with the omit-to-publish-all behavior. The description adds nuance by mentioning 'every player in the tenant' and the batch failure context, which goes beyond the schema description. Thus it adds value above the 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 a specific action ('Build a fresh content snapshot') with a clear resource ('player') and outcome ('picks up its current content assignment'). It also distinguishes this tool from sibling tools by focusing on the publishing flow, not playlist management.

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?

Explicit 'When to use' and 'When NOT to use' sections provide clear guidance, including a concrete trigger ('update_player returned publish_required: true') and an explicit exclusion case (field-only rename). This fully satisfies the dimension.

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