persona.validate

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

With no annotations, the description carries full behavioral burdenasia it only says 'Return actionable diagnostics' and does not disclose whether validation is read-only, whether it checks syntax/semantics/deployment, or how failures are reported. This is minimal behavioral transparency.

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?

A single, front-loaded sentence with no filler. It communicates the core action and object economically, though it does sacrifice some contextual detail.

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 validation tool with an output schema, the description is minimally viable but lacks usage context, parameter semantics, and behavioral assurances. It is complete enough for a simple call, but not for confident routing or edge-case handling.

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 schema has 0% description coverage and one optional persona_id parameter, but the description adds no parameter-level guidance. The agent must infer that persona_id scopes validation, and the meaning of a null default is left ambiguous.

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 clearly names a specific verb ('Return') and resource ('actionable diagnostics for declarative persona packs'). It implies validation of persona definitions)Skip comparing to siblings like skill.validate, but does not explicitly name them or distinguish itself.

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 guidance is provided about when to use this tool versus alternatives such as skill.validate or persona.list. There are no exclusions, prerequisites, or typical use-case context, leaving the agent to infer suitability.

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