Create DRep Registration Certificate

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

Annotations already declare readOnlyHint=false, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds nothing beyond that: it does not say the certificate is only written to a file and still needs to be wrapped in a transaction, nor what the output artifact looks like.

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?

The purpose sentence is properly front-loaded, but the following args list duplicates all five parameters that the schema already documents completely, adding length without information. Half the text is redundant.

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 mutation tool with no output schema, the description omits what file is produced, how it integrates with transaction_build/transaction_sign, and whether an existing out_file is overwritten. The required-vs-optional anchor pairing is also 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 100%, and the description simply restates each schema property description verbatim. With the schema fully documented, the baseline of 3 applies — no extra meaning such as deposit-source rules or anchor pairing constraints is added.

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 states a specific verb+resource ("Create a DRep registration certificate"), which is enough to distinguish it from the retirement/update certificate siblings that appear in the tool list. However, it never names or contrasts those siblings explicitly, so the differentiation is left implicit.

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 versus cardano_governance_drep_update_certificate or the retirement variant, nor any prerequisites (e.g., that a DRep key must first be generated, or where the deposit amount comes from). An agent must infer the whole workflow.

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