activate_domain

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

No annotations are provided, so the description must bear the burden of disclosing behavior. The description only states the basic action and a prerequisite, but does not mention any side effects, permissions, or reversibility of activation. It also has a broken placeholder 'Domains: .'.

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 (2 sentences), but includes a confusing broken fragment 'Domains: .' which detracts from conciseness. It is front-loaded with the main action but ends with an incomplete thought.

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 the lack of annotations and output schema, the description should provide more context, such as the list of available domains or what 'activation' entails. It fails to do so, leaving the user uncertain about the domains that can be activated.

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 input schema has 100% description coverage for both parameters, so the description does not need to add much. It does not elaborate on the parameters beyond the schema, so it meets the baseline for no added value.

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 action: 'Activate all tools in a domain at once.' It distinguishes from siblings like 'activate_tools' (which likely activates individual tools) by specifying it operates on a whole domain. However, the incomplete sentence 'Domains: .' reduces clarity.

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 gives a prerequisite: 'Use reload_extensions first...', which implies when to use it. But it does not explicitly contrast with alternatives like 'activate_tools' or state when not to use this tool.

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