Create New Op Cert Counter

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 and repeatability profile is covered structurally. The description adds only the fact that a file is written to operational_certificate_counter_file; it says nothing about whether an existing counter file is overwritten, what permissions or node state are required, or the counter's role in op-cert issuance.

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 single purpose sentence is front-loaded and clear, but the Args list is a straight duplication of the input schema and therefore does not earn its place. The overall size is small, so the waste is moderate rather than severe.

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 three-parameter, all-required tool with no output schema, the description covers the inputs but is silent on return behavior and on the operational workflow linking this counter to op-cert issuance. It is minimally adequate rather than complete.

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 the baseline is 3. The Args block in the description restates the three schema descriptions verbatim (counter value, key file path, output path) and adds no format, range, or domain 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 names a specific verb and resource (create a new operational certificate counter) and specifies the output artifact, so an agent can identify the operation. It does not differentiate itself from nearby siblings such as cardano_node_issue_op_cert, which also revolves around operational certificates, leaving the boundary to inference.

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 how this tool relates to the sibling cardano_node_issue_op_cert that consumes such a counter file. The description only states what happens, not when an agent should choose this over alternatives.

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