Generate Stake Key Pair

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

Annotations already declare readOnlyHint=false, idempotentHint=false, destructiveHint=false, so the agent knows this is a non-repeatable write. The description adds the file-output nature and the return value, but never addresses what happens if the target files already exist, whether directories must exist, or key file permissions — meaningful gaps for a write-to-disk tool.

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?

Front-loaded with the core action in one sentence, then compact Args/Returns sections. Efficient and easy to scan, though the Args block is pure duplication of the schema.

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 no output schema, the description does supply a minimal return statement, and annotations cover the safety profile. Still missing file-overwrite behavior and environment assumptions, which matter for a key-material write operation, so it is only minimally adequate.

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 both parameters are already documented in the schema, and the description repeats them verbatim without adding format, permission, or overwrite semantics. Baseline 3 is appropriate when the schema does all the work.

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 and resource ('Generate a stake signing and verification key pair'), which is clear and unambiguous on its own. However, it offers no differentiation from the many adjacent key-generation siblings (cardano_key_generate_payment, cardano_stake_address_key_gen, cardano_stake_pool_key_gen), leaving the agent to infer selection from the name alone.

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 mention of alternatives. Nothing tells the agent when a stake key is the right choice versus a payment or stake-address key, which is a real risk given the crowded sibling set.

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