redis_update_persistence_conf

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

No annotations are provided, so the description carries the full burden of behavioral disclosure for a mutation tool. It says nothing about whether changes require a Redis restart, whether they apply at runtime, required permissions, or reversibility - all critical for a live persistence-config change.

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 single clause is short, but it is under-specified rather than concise - it omits all information an agent would need. Brevity here reflects missing content, not efficient editing.

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 4-parameter mutation tool with no annotations, no output schema, and zero parameter documentation, the description is completely inadequate. Nothing about parameters, side effects, or return behavior is conveyed.

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 description coverage is 0% across 4 parameters (id, save, appendonly, appendfsync), and the description adds no meaning for any of them. An agent cannot tell what values 'save' expects, what 'appendfsync' policies are valid, or what 'id' identifies.

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 a verb (Update) and resource (Redis persistence), which is enough to distinguish it from the read-side sibling redis_get_persistence_conf. However, it gives no indication of which persistence settings are being updated, so the purpose is only generically clear.

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?

There is no guidance about when to use this tool versus redis_update_conf, redis_get_persistence_conf, or redis_get_conf. No prerequisites, no context, no exclusions are provided.

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