phpipam.addresses.allocate

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

No annotations are provided, so the description carries the full burden of disclosure. It mentions the write-enable requirement and that allocation picks the first available IP, but it does not specify return values, failure modes (e.g., subnet full), persistence guarantees, or any other side effects. For a mutating tool this is a significant transparency 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?

The description is a single, front-loaded sentence that directly states the purpose and the critical environment requirement. Every word is useful; there is no redundancy or fluff.

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?

With no output schema, the description should ideally mention what the tool returns or how to interpret success, but it only covers the core action and the write-enable prerequisite. For a simple allocation tool with well-described parameters, it is minimally adequate but leaves important context (e.g., returned IP, error behavior) unstated.

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 already provides descriptions for all 6 parameters (100% coverage), so the baseline is 3. The description adds no parameter-level detail beyond 'in a subnet', but it also does not need to since the schema already documents each parameter clearly.

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 ('Allocate'), the resource ('first available IP address in a subnet'), and the scope ('in a subnet'). It distinguishes itself from sibling tools like release (frees an address) and upsert (sets a specific address) by emphasizing automatic first-available allocation.

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 gives an important usage precondition (PHPIPAM_WRITE_ENABLED=true) and implies the tool is for automatically assigning a free IP rather than a specific one. However, it does not explicitly compare itself to alternatives like addresses.upsert or addresses.release, nor does it state when not to use it.

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