manage_persistence

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 does not disclose behavioral traits such as mutability (e.g., 'store_data' is a write operation), required permissions, or side effects. The minimal description adds no behavioral context beyond what the schema implies.

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: one sentence plus a list. It is front-loaded but lacks detail. It is not overly verbose, but it misses important information that would justify its length. It earns a 3 as minimally acceptable.

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?

With 7 parameters, 5 actions, no output schema, and no annotations, the description is insufficient. It does not explain return values, error handling, or relationships between parameters. The schema partially compensates, but the description alone does not provide a complete picture for an agent to invoke the tool correctly.

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 86%, which is high, so the baseline is 3. The description adds no additional meaning beyond the schema; it only lists actions that are already in the enum. The parameter descriptions in the schema already tell which params are used by which actions, so the description does not improve semantics.

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 the tool handles 'Persistence data operations' and lists specific actions (services, get_data, store_data, etc.), making the purpose clear. However, the phrase 'Persistence data operations' is somewhat generic; a more specific verb+resource would improve clarity. It does distinguish from siblings like 'manage_item' or 'manage_logs'.

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 sibling tools. The description simply lists sub-actions without mentioning prerequisites, alternatives, or exclusion criteria. An agent would not know when to choose this over 'manage_item' or 'manage_logs' for data operations.

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