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

Annotations already declare readOnlyHint=true and destructiveHint=false, so no side-effect warning is needed. The description adds a genuinely useful behavioral detail: the prepared binding is tied to the current ownership epoch, and a later publish step revalidates ownerOf and epoch, meaning the prepared text can become stale.

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?

Two compact, front-loaded sentences contain the essential purpose and an important validity warning. The second sentence is slightly cryptic because 'Publish' is not identified as an operation, but overall the description is well structured and waste-free.

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?

Given the full parameter schema, output schema, and safety annotations, this description gives an agent enough context to call the tool correctly. The only minor gap is the undefined 'Publish' step, but it does not prevent correct invocation.

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 input schema already describes all four required parameters at 100% coverage, so the baseline is 3. The description adds conceptual glue among principal, space, transport, and current epoch, but it does not provide additional field-level detail beyond the schema.

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 is specific: it prepares an EIP-191 text binding the current ownership epoch to one Tasq principal, space, and transport. It is clearly distinct from the many sibling prepare_* tools and from get_tasq_principal_binding, though it does not explicitly name an alternative.

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 idea of 'prepare' plus the mention that publish later rechecks ownerOf and epoch implies this is an async pre-publication step. However, the description does not explicitly say when to use this tool versus get_tasq_principal_binding, nor does it outline prerequisites such as valid current ownership.

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