pvsyst_license_info

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

With no annotations, the description carries the full burden, and it does add one genuinely useful disclosure: keys and Host ID are intentionally withheld from the response. However, it says nothing about whether the CLI must be running, whether the call requires authentication, or what happens if no license is present.

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 dense sentence with the scope caveat front-loaded; nothing is wasted. The '[Setup & License]' prefix is mild redundancy against the tool name, which keeps it just short of a 5.

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?

There is no output schema, so the description must hint at return contents, and it only names 'state and quota' without any shape or field detail. For a zero-parameter, no-annotation tool this is serviceable but leaves the agent guessing what it will get back.

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?

The tool takes zero parameters, so there is no parameter semantics to document and the baseline of 4 applies.

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?

States a specific verb and resource: 'Read CLI license state and quota.' The sibling set (license_activate, license_deactivate, license_sync) makes the read-only variant distinguishable, though the description never explicitly contrasts itself with those siblings.

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 by the word 'Read' and the bracketed '[Setup & License]' tag. The description gives no explicit when-to-use guidance, no prerequisites (e.g., does the license need to be activated first?), and no reference to the sibling license_* tools that an agent must choose between.

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