quipu_namespaces

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true; "no writes or allocation" largely restates those hints. The genuinely non-obvious behavior — what "effective" resolution means (inherited vs. explicitly owned namespaces), whether results are tenant-scoped, and whether the list can be empty — goes unaddressed.

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?

One front-loaded sentence with the operation stated first and the scope constraint second; no filler. The trailing "no writes or allocation" clause is near-redundant with the annotations, which is the only wasted wording.

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 one-parameter read-only listing tool this is close to sufficient, but with no output schema the description could have indicated what a returned namespace entry contains or what "effective" means. As written, an agent knows it gets a namespace list but not how to interpret the results.

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?

There is a single optional parameter, action, with a one-value enum ("list") and 0% schema description coverage. The description's verb "List" implicitly maps to that enum value, so nothing is truly ambiguous, but no added meaning beyond the schema is provided.

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 ("List") and resource ("owner namespace registry"), so an agent knows this is a read of namespace metadata. However, "effective" is unexplained jargon and the description does not differentiate this from adjacent registry-like siblings such as quipu_datasets, quipu_shapes, or quipu_context.

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 writes or allocation" rules out a category of behavior but gives no when-to-use condition and names no alternative tool. An agent cannot tell from this text whether to call quipu_namespaces or quipu_datasets/quipu_shapes to discover available scopes.

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