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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds the scope of what is loaded (identity, permissions, skills, context), which is useful, but says nothing about failure modes, required authorization, or what happens when the referenced agent cannot be resolved. With annotations doing the heavy lifting, a 3 is appropriate.

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 the verb first and zero filler. It is tight, though arguably undersized for a five-parameter tool with a resolution/mount semantic.

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 and annotations exist, so return values and the safety profile need not be described. The remaining gap is selection guidance: the description does not explain that at least one of agentId/agentWallet must be supplied or how controllerWallet defaults, leaving the caller to reconstruct intent from the schema.

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 100%, so the schema already explains agentId, agentWallet, identityQHash, controllerWallet, and requiredResources. The description adds no parameter-level meaning, such as the interplay between agentId and agentWallet or how requiredResources is enforced. Baseline 3 applies when the schema carries the 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 names a specific verb ('Load') and a concrete set of resources (agent identity, permissions, skills, context) plus the destination ('into this project'). However, it does not distinguish itself from siblings such as proofable_agent_create or proofable_agent_link, so an agent cannot tell from the text alone why it would mount rather than create or link an agent.

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 when-to-use guidance, no prerequisites, and no reference to alternatives among the many agent/proof/secret siblings. The agent must infer from the name alone that this resolves an existing agent into the project rather than creating or linking one.

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