get_kv_namespace

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

No annotations are present, so the description carries the full burden of behavioral disclosure. 'Get details' implies a read, but it does not state that the operation has no side effects, what happens for a missing namespace, or what the returned details contain. This is too thin to fully compensate for the absence of annotations.

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 a single concise sentence with no filler and the key idea is front-loaded. It is appropriately brief for a simple two-parameter getter, though it sacrifices behavioral richness for brevity.

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 no output schema and no annotations, the description should explain what 'details' actually include or what the response looks like. It only says 'details' without specifying namespace metadata, so an agent cannot predict the return shape or interpret the result confidently.

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 already describes both parameters with 100% coverage, so the baseline is 3. The description adds no extra meaning about how account_id or namespace_id should be formatted or where they come from, but the schema covers the essential 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 uses a clear verb ('Get') and resource ('a KV namespace'), so an agent can tell it retrieves a single namespace rather than listing namespaces. It doesn't explicitly name sibling tools like list_kv_namespaces or distinguish itself from list_kv_keys, so it stops short of the strongest scoring.

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 choose this tool over list_kv_namespaces or list_kv_keys, and no indication that a namespace must already exist or that account_id/namespace_id should be obtained from a prior call. The description leaves all usage decisions to the agent.

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