syncthing_overview

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. The word 'bounded' hints at pagination behavior, which is a small but real addition, yet nothing is said about what the overview returns, how it aggregates instance and folder data, or how pagination terminates.

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?

A single front-loaded sentence with no filler is structurally efficient. It is arguably too terse for the information load, but there is no wasted verbosity to penalize.

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?

An aggregate tool with four undocumented parameters, no output schema, and dozens of overlapping siblings needs more than one sentence. Nothing tells the agent what the overview contains, how it relates to the granular sibling tools, or how to page through it.

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% for four parameters (limit, cursor, fields, instance), so the schema gives no semantic help. 'Bounded' loosely gestures at limit/pagination but does not explain cursor semantics, what fields accepts, or how instance scopes the overview, leaving the bulk of parameter meaning 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 names a resource ('overview of this instance and folder synchronization state'), which is more specific than a bare restatement of the name. However, 'overview' and 'bounded' are vague, and it does not distinguish this aggregate tool from granular siblings such as syncthing_system_status, syncthing_folder_status, or syncthing_instances, so an agent cannot tell when the overview is preferable.

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 on when to use this tool versus the many narrower siblings, no prerequisites, and no exclusions. The name implies it is a starting-point summary, but the description never states that, leaving usage entirely to inference.

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