Register HTTP Target

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

Annotations indicate a write operation (readOnlyHint=false) and no destructive behavior. The description adds meaningful context beyond annotations: GET-only restriction, supported assertion types, and allowlist requirements for private origins. There is no contradiction with annotations.

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 is a single, well-structured sentence that front-loads the verb and resource type. Every phrase provides useful information without redundancy.

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?

The description covers the core behavior, supported assertion types, and network constraints. It lacks explicit return-value or setup details, but no output schema exists and the tool is reasonably scoped. Sufficient for a registration tool.

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?

The input schema has zero parameters, so baseline is 4. The description mentions endpoint and assertion types, but there are no parameters to document. This is acceptable given the empty 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 clearly states the action ('Register'), the resource ('GET-only HTTP or HTTPS endpoint'), and the specific features (status, header, body, JSON, TLS-expiry assertions). This distinguishes it from sibling register tools for GitHub Actions, GitLab pipelines, and servers.

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 implies use for HTTP/HTTPS monitoring targets and provides context on network restrictions and prerequisites for private origins. It does not explicitly name alternatives, but sibling tools make the differentiation clear enough.

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