Выпуск SSL-сертификата для поддомена S3-хранилища

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

Annotations already convey that the operation is not read-only and not idempotent. The description adds useful behavioral context by referencing Let's Encrypt and stating that the subdomain must be pre-added with a correct CNAME record. No contradictions with annotations were found.

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 description consists of two short, focused sentences. It front-loads the core action and adds one prerequisite sentence, with no redundant or filler words.

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 single-parameter tool without an output schema, the description provides the essential purpose, prerequisites, and a key requirement (CNAME). It is sufficiently complete, though it could optionally mention error handling or issuance time, which are not critical.

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 coverage for the single 'subdomain' parameter is 100%, so the baseline is 3. The description adds extra meaning by specifying that the subdomain must be tied to an S3 bucket and must meet CNAME requirements, which goes beyond the raw schema description.

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 clearly states the tool's function: issuing an SSL certificate (Let's Encrypt) for an S3 bucket subdomain. It uses a specific verb ('выпускает') and names the resource, distinguishing it from sibling tools like add_bucket_subdomains and list_bucket_subdomains.

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?

The description explicitly names the prerequisite tool (add_bucket_subdomains) and mentions the required CNAME record, telling the agent when this tool can be used. It does not explicitly list alternatives for when not to use it, but the context is clear enough.

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