pbs_namespace_create

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

Describes mutation behavior, dry-run default, confirm flag, and return value. No annotations provided, so description covers full burden. Lacks mention of authorization requirements or rate limits, but sufficient given context.

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?

Three concise sentences front-loading the verb and critical info (dry-run, confirm). No unnecessary words; every sentence adds value.

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?

Covers purpose, usage, behavior, and references siblings. Missing prerequisites like authentication or datastore existence, but output schema is described in description. Adequately 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?

Schema covers all parameters with descriptions (100% coverage). Description does not add additional parameter meaning beyond schema, meeting the baseline.

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?

Clearly states 'create a namespace within a PBS datastore', specifying verb (create) and resource (namespace). Differentiates from siblings by referencing pbs_namespaces_list and pbs_namespace_delete.

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 advises to use pbs_namespaces_list to check for name collisions first, and pbs_namespace_delete to remove one. Also explains dry-run vs confirm=True usage.

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