syncthing_devices

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. However, the description adds nothing beyond that: no mention of pagination behavior, what is enumerated, or the remote/open-world nature of the call implied by openWorldHint.

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?

One word is short but not concise in a useful sense — it is under-specification rather than economy. There is no front-loaded statement of purpose to build on.

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 tool with four undocumented parameters, no output schema, and a large family of near-identically named device/folder siblings, the description is completely inadequate. An agent has no basis for selecting or correctly invoking this tool.

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 description coverage is 0% across all four parameters (limit, cursor, fields, instance). The description does not name, explain, or hint at any of them, so pagination via limit/cursor and field projection via fields are entirely undocumented.

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 is the single word "Devices.", which merely restates the tool name syncthing_devices. It gives no verb and no indication of what is being done with devices (list, fetch, summarize), so an agent cannot distinguish it from syncthing_device_config, syncthing_device_defaults, syncthing_device_statistics, or syncthing_pending_devices.

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?

There is no guidance whatsoever about when to use this tool, when not to, or which sibling to prefer for device-related data. The agent must guess based on the name alone.

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