list_personas

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

With no annotations, the description carries the full behavioral burden. 'List' implies a safe read, but the description says nothing about pagination, how 'limit' behaves, ordering, or result caps — all relevant for a listing tool with a default limit of 100.

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 short, front-loaded sentence with no filler, which is structurally clean. But the terseness is under-specification rather than economical writing — it omits information an agent needs rather than trimming excess.

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?

An output schema exists, so return shape need not be described. Still, with no annotations, an undocumented limit parameter, and no sibling differentiation, the definition leaves key agent decisions unaddressed.

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 0% and the single parameter (limit, default 100) is not mentioned or explained in the description. Since coverage is far below 50%, the description was expected to compensate and does not.

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 ('personas') plus the source system ('Persona Studio'), so the agent knows exactly what it returns. However, it offers no differentiation from close siblings such as list_shadow_personas or list_studio_catalogue, leaving ambiguity about which persona-listing tool to pick.

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 on when to use this tool versus the many other list_* siblings (list_shadow_personas, list_crews, list_workspaces, etc.). No prerequisites, no exclusions, no alternatives are named; usage must be fully inferred.

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