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

Annotations already declare it is a non-read, non-destructive mutation; the description adds the genuinely useful behavioral fact that module settings are kept when toggled off, which is exactly the risk an agent would otherwise have to guess at. It does not explain plan gating, permission requirements, or whether disabling takes the public page offline, so it stops short of full disclosure.

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 the action and object stated first, followed by a compact inline list that earns its space by defining each module. The closing sentence on retained settings is four words and carries an important guarantee.

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 three-parameter toggle with full schema coverage and no output schema, the definition gives an agent enough to call it correctly and tells it settings survive toggling. Missing is any statement of what a caller gets back or whether the change propagates immediately to the public site, which matters for a live-site mutation.

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 coverage is 100%, so the baseline is 3, but the description goes beyond the schema by explaining what each enum value actually is (feedback = feature request board, remote_config = app-config.json for force updates/maintenance/notices, press = press kit). The enum in the schema carries only bare names, so this gloss is real added meaning for selecting the right module.

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 concrete verb (turn on/off) and resource (one of the site's extras), then enumerates every module with a one-line gloss so the agent knows exactly what can be toggled. The only gap is that it never distinguishes itself from the set_remote_config sibling, even though 'remote_config' is one of the modules listed here, which could leave an agent unsure which tool configures versus enables that module.

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 when-to-use is implied by the enable/disable semantics and the enabled flag, but nothing is said about checking current state first (get_modules exists as a sibling) or about the relationship with set_remote_config. No exclusions or prerequisites are stated, so the agent must infer the workflow.

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