Generate KES Key Pair

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

Annotations already disclose readOnlyHint=false, destructiveHint=false, idempotentHint=false, openWorldHint=false, so the safety profile is partly covered. The description adds that the operation writes key material to two file paths, but it omits the genuinely useful behaviors: whether existing files are overwritten, whether parent directories are created, and what (if anything) is printed on success. For a key-material writer that is a meaningful gap.

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 single-sentence purpose followed by a compact Args list. Every line is short and readable, though the Args block duplicates the schema descriptions rather than adding anything new.

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?

A simple two-parameter tool with no output schema, so the description need not explain return values. However, it leaves unanswered the practical details an agent needs for a file-writing crypto operation: overwrite behavior, directory assumptions, and failure modes.

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 both parameters are fully documented in the schema; the description merely repeats the same text verbatim. Baseline 3 is appropriate – it adds no syntax, format, or constraint information 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?

States a specific verb (Generate) and resource (KES key pair) scoped to 'for a stake pool', which cleanly separates it from cardano_stake_pool_key_gen, cardano_stake_pool_vrf_key_gen and cardano_node_key_gen_kes. It does not explicitly name those siblings, but the resource is distinct enough to select correctly.

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 statement of when to use this tool versus the many sibling key-generation tools, nor any prerequisite (e.g. whether a pool key must already exist, whether files may already exist). Usage is only implied by the tool name.

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