trmnl_update_fleet_settings

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

Annotations state this is a non-read-only, non-idempotent, open-world call; the description adds the important detail that the list is REPLACED rather than merged, and that the inheritance takes effect on each push. That is real behavioral context beyond the annotations, though it omits any error or permission behavior on the remote call.

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 core intent is front-loaded, but the opening line is an unpunctuated fragment and 'Changes remote state or starts work' is generic filler that adds little. Some tightening would help.

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 output schema and only 33% parameter coverage, the description covers the main semantics (replace, empty-list fallback, effect on push) but leaves the profile parameter and enum values unexplained and gives no indication of the response.

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 only 33%, and the description usefully explains that an empty inherited_settings list copies the playlist only. However, it says nothing about the installation_id path parameter, the profile parameter, or the four allowed enum values, so the compensation is partial.

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?

Opens with a specific verb and resource: choosing which settings mirrors inherit from the master, plus the concrete endpoint (PATCH /api/apps/fleet/{installation_id}/settings). This separates it from related fleet tools like trmnl_set_fleet_master and trmnl_update_fleet_alerts, though it doesn't name those siblings explicitly.

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?

'Each push copies these settings from the master' implies it is used before or alongside a fleet push, but there is no explicit when-to-use versus trmnl_push_fleet or trmnl_set_fleet_master. The only guardrail is the generic 'Run only within the user-authorized scope' line.

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