trmnl_push_fleet_device

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false and openWorldHint=true, so the bar is lower. The description still adds genuine context beyond them: the call is asynchronous ('Queues the push'), and the mirror adopts the master playlist plus inherited settings once it runs. It stops short of saying how to confirm completion, which would have made it a 5.

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?

Four short sentences, front-loaded with the action and effect, then the endpoint and safety note. 'Changes remote state or starts work' slightly restates what readOnlyHint=false already conveys, but it is brief enough not to be wasteful.

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 non-idempotent, open-world mutation with a nested path object and no output schema, the description covers the essential async semantics and the resulting device state. The missing piece is how to verify that the queued push completed, though sibling read tools exist for that.

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 50%, so the description must carry some weight. It partially compensates by exposing the route template with {installation_id} and {device_id}, clarifying what those path values mean, but the optional 'profile' parameter is never mentioned. Baseline 3 is appropriate given the partial coverage.

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 first sentence states a specific verb, resource and scope: push the master playlist to one mirror. The 'one mirror' phrasing implicitly separates it from trmnl_push_fleet, but the sibling is never named, so an agent must infer the distinction from tool names alone.

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 implied rather than stated: 'Run only within the user-authorized scope' is a safety caution, not a when-to-use rule. Nothing tells the agent when to prefer this over trmnl_push_fleet or trmnl_resync_device_mirror, so the agent must infer from scope wording.

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