register_model

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

With no annotations, the description carries the full burden of behavioral disclosure. It only says 'register,' which implies a write operation, but it does not state side effects, idempotency, permissions, reversibility, or what output to expect. This is a serious gap for an action that likely creates a persistent record.

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, efficient sentence front-loaded with the verb and object. It wastes no words and is easy to parse. However, its brevity borders on under-specification, so it does not earn a 5 for structure.

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 tool with 4 parameters, no annotations, and an implied mutation, this description is far too thin. It lacks usage context, parameter explanations, behavioral details, and any sense of what the tool accomplishes beyond a vague registration. An agent cannot confidently call it correctly.

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 0%, so the description must compensate for the 4 parameters (model_key, access_path, provider, metadata). The phrase 'model/access-path identity' only hints at two of them, and provider and metadata are left entirely unexplained. No parameter-level meaning is added.

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 uses a specific verb ('register') and names its resource ('model/access-path identity') with a purpose clause ('for empirical execution comparisons'). This distinguishes it from sibling registration tools like register_contract, though it does not explicitly name alternatives. It is clear but could be more concrete about what 'register' entails.

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?

No guidance is given on when to use this tool versus alternatives, no prerequisites, and no exclusions. The phrase 'for empirical execution comparisons' hints at a use case, but it does not tell the agent when to prefer this over register_contract or other siblings.

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