redis_config_set

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

No annotations are present, so the description carries the full burden. It fails to disclose behavioral traits such as potential side effects, permission requirements, or persistence behavior. For a configuration mutation, these details are critical for safe usage.

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 extremely short (one line). While concise, it sacrifices necessary detail. A more structured description could include usage notes without significant bloat.

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?

Despite presence of an output schema (not shown), the description lacks important context about the nature of the configuration change, such as whether it is immediate, persistent, or requires a restart. This is insufficient for a potentially destructive operation.

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 provides full descriptions for both parameters (name and value), achieving 100% coverage. The description adds no additional semantics beyond the schema, meeting the baseline without adding extra 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 states 'Set Redis configuration,' which uses a specific verb and resource. It clearly indicates a set operation for Redis configuration, distinguishing it from the sibling redis_config_get. However, it could be more specific about the type of configuration (e.g., server settings).

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?

No guidance is provided on when to use this tool versus alternatives. While it is a set operation for configuration, there is no explanation of context, prerequisites, or when not to use it (e.g., for transient settings or key-value stores).

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