plugins_install_url

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

With no annotations, the description carries the full behavioral burden, but it only says 'Install a plugin from a URL.' It does not disclose side effects, whether an existing plugin is overwritten, whether a restart is needed, what confirmation actually gates, or any permission requirements.

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 description is short and front-loaded with the core purpose, and the Args list is compact. However, the 'confirm: Required.' line is ambiguous and potentially contradictory, which slightly undermines its value.

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 mutating install operation with no annotations, the description is too thin. It omits what installation does to the system, what 'confirm' means, whether the operation is idempotent, and how it relates to existing plugin versions. The output schema may cover return values, but behavioral and safety context is missing.

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 does add useful meaning for url ('https URL to a .tar.gz plugin'), but the confirm parameter is only described as 'Required,' which contradicts the input schema where confirm is optional with a default of false. This is misleading and incomplete.

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 states a specific action and resource: 'Install a plugin from a URL.' This clearly distinguishes it from sibling plugin tools like plugins_list, plugins_activate, and plugins_delete, especially since the sibling list contains no other install-by-URL tool.

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 only implied: use this when installing a plugin from a URL. There is no explicit guidance about when to prefer this over related plugin operations, no prerequisites, and no alternative tool mentioned.

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