Generate Address Key Pair

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

Annotations already declare destructiveHint=false, idempotentHint=false and openWorldHint=false, so the safety profile is supplied structurally. The description adds that the operation writes keys to disk paths and returns only a confirmation, but it omits important behavior such as whether existing files at those paths are overwritten and whether the keys are written to a specific network/format.

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-loads the purpose in the first sentence and uses a tight Args/Returns layout with no filler. Minor redundancy: the Args block restates exactly what the schema already documents.

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 two-parameter, no-output-schema tool the description is minimally sufficient — the args are covered and the return is characterized as a confirmation. It stops short of the details that matter for a key-generation write (file overwrite behavior, key format, downstream use of the generated keys).

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 reproduces the two parameter descriptions verbatim ('Output path for the verification/signing key') without adding format, overwrite, or directory-existence semantics. Baseline 3 applies since the schema already carries the parameter meaning.

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 (generate) and resource (a payment address key pair of verification + signing keys), which is more precise than the title alone. However, it never distinguishes itself from the closely named siblings cardano_key_generate_payment and cardano_stake_address_key_gen, leaving an agent unsure which key-pair generator applies.

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 the other key-generation tools, nor any prerequisite or ordering advice (e.g. that the resulting signing key feeds cardano_transaction_sign). The only context is the implicit 'payment' qualifier.

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