Manage PubNub Keyset

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

No annotations are provided, so the description carries the full burden. It discloses that create sets default values for certain features, but it lacks information on authorization, rate limits, or whether update is partial or full replacement. Some behavioral traits are mentioned but gaps remain.

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 uses bullet points and is well-structured. It front-loads the overall purpose and then details each operation. It is relatively concise, though could be slightly more terse without losing meaning.

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 complex tool with 4 operations and no output schema, the description covers key aspects like required fields, defaults, and operation-specific instructions. It does not mention return values or error handling, which would be beneficial, but given the complexity, the description is reasonably complete.

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 baseline is 3. The description adds value by summarizing parameter usage per operation (e.g., 'for create: {name, appId?, type, config}') and explaining the structure of config. This helps the agent understand the complex nested parameters beyond the schema.

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 tool manages PubNub keysets with four distinct operations: get, list, create, update. It uses specific verbs and resource (keysets), distinguishing it from sibling tools like manage_apps or manage_app_context.

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 provides clear context for each operation (e.g., 'get' requires keyset ID, 'create' requires name and type and config). It includes guidance like asking for missing parameters. However, it does not explicitly compare to alternatives 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.
