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

With no annotations, the description carries the full burden, and it discloses the non-obvious behavioral trait: writes are queued in memory and only this call makes them durable. It does not cover idempotency, blocking behavior, failure modes, or permission requirements, but the durability semantics are the key missing piece and they are present.

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, zero waste, with the core action front-loaded before the explanatory context about queued writes. Every clause 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?

For a single-parameter tool with no output schema, the description covers the essential mental model of the write queue and durability. It omits error/return behavior and whether all write paths are covered by the queue, which keeps it from being fully 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?

Only one parameter, and schema description coverage is 100% ('Database name'), so the schema already does the work. The description's phrase 'this database' adds no syntax, format, or scope detail beyond the schema, making the baseline 3 appropriate.

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+resource: 'Flush pending writes for this database to disk.' It also distinguishes itself from sibling write tools by explaining the in-memory queue model, so an agent can tell it apart from apply_structure or aql_write without opening a schema.

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 names the triggering siblings ('Edits via edit_name_attributes, apply_structure, AQL edit: primitives etc. are queued in-memory; call this to make them durable'), which is clear when-to-use guidance. It stops short of saying when persistence is unnecessary or whether it is mandatory after every write.

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