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

Annotations cover the safety profile (readOnlyHint=false, idempotentHint=true, destructiveHint=false), and the description adds genuinely new context: writes live in an in-memory queue and this call is what makes them durable. It does not mention whether flushing with nothing pending is a no-op or an error, but the core behavioral model is disclosed.

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?

Two sentences, no padding, with the core action front-loaded and the triggering tools in the supporting clause. Every sentence earns its place.

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?

No output schema exists, and the annotations already carry the safety profile, so the description's job is to explain the in-memory queue model, which it does. Minor gaps remain around failure/no-op behavior when nothing is pending.

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 100%, with 'database' documented and 'business' richly explained in the schema (including multi-business write guidance). The description adds nothing parameter-specific, so the baseline 3 applies.

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?

States a specific verb and resource: flushing pending writes to disk for a named database. This is clearly distinguishable from siblings like apply_structure or aql_write, which produce the queued writes rather than persisting them.

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?

Explicitly tells the agent when to call it: after edits made via edit_name_attributes, apply_structure, and AQL edit primitives, which are queued in-memory. It names the producing tools and the durability goal, though it gives no explicit when-not-to-call case (e.g. no pending writes).

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