Compute on a sealed tower in transit

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

Annotations already declare readOnlyHint=false, idempotentHint=true, destructiveHint=false and openWorldHint=true, yet the description adds meaningful context: the seal is verified before execution, a broken seal causes refusal with no charge, and cost is one job per operation. That is real behavioral value beyond the annotations, though what twist_in_transit overwrites is only implied.

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?

Purpose is front-loaded, followed by operations, safety behavior, inputs, and cost in a logical order. The 'sealed tower' metaphor is repeated enough to add some noise, but every sentence still conveys operational information.

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?

With annotations covering safety and an output schema covering return values, the description fills the remaining gaps: operation meanings, seal-verification behavior, required inputs, and cost. Only minor details (e.g., how params are structured and what 'portal energy' reports) are left 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 'op' has no enum, so the description must carry the load. It supplies the valid op values and their semantics plus the sub-parameters (tower_in path, tower_out for twist, ridge), which the schema does not expose. It is slightly ambiguous about how these nest under the opaque 'params' object, keeping it from a 5.

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+resource (compute on a sealed tower in transit) and enumerates three concrete operations (fuse_in_transit, twist_in_transit, energy_audit), which lets an agent distinguish the modes of this tool. It does not explicitly differentiate itself from siblings like mind_merge_v2 or mind_combine_v2, so it stops short of a 5.

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?

The operation list implies what each mode is for, but there is no explicit when-to-use / when-not guidance or named alternative (e.g., versus mind_merge_v2 or data_carry). Usage must be inferred from the operation glosses.

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