update_hub_setting

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

Annotations indicate readOnlyHint=false, so the tool is known to be mutating. The description adds valuable behavioral context: backup creation, restart requirement, and confirm=true necessity, which go beyond the annotation flags.

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?

Three concise sentences front-loaded with the purpose, followed by essential behavioral notes. No redundant information.

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?

Given no output schema, the description covers core aspects: functionality, path syntax, side effects (backup, restart), and a crucial input requirement (confirm=true). Missing details on errors or return values, but still informative for an agent.

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%, so the description must compensate. It explains the dotted path format for key_path and stresses that confirm must be true, but does not describe the 'value' parameter. This partial coverage is adequate but not thorough.

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 the tool sets a Hub setting value, using dotted path notation (e.g., 'download.maxConcurrentDownloads'). It distinguishes itself from sibling tool 'get_hub_settings' by focusing on updating rather than reading.

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?

The description explicitly states that confirm=true is necessary and that changes take effect after a Hub restart. However, it does not specify when not to use this tool or compare to alternatives beyond the implicit sibling distinction.

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