List CCU Targets

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

Annotations already declare readOnlyHint=true, and the description adds critical safety information: 'Never exposes passwords'. This goes beyond the annotation to assure the agent that sensitive credentials are not leaked.

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?

Single sentence that efficiently conveys all necessary information without extraneous words. Purpose is front-loaded and every part of the sentence adds 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?

Given no parameters and an output schema present, the description fully explains what the output contains and the tool's role relative to use_ccu. No gaps in information.

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?

No parameters exist in the schema, so the description does not need to elaborate on parameter meaning. Base score of 4 for zero parameters is appropriate.

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?

Description clearly states it lists CCU targets, specifies exactly what information is included (name, host, user, protected/read-only, active, login state), and distinguishes from the sibling tool use_ccu by noting these are profiles to switch between.

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?

Implicitly indicates use before use_ccu by saying 'you can switch between with use_ccu', providing context on when to retrieve this list. However, it does not explicitly state when not to use this tool or mention alternatives beyond use_ccu.

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