set_model_allowlist

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

No annotations provided, so description carries full burden. It adds '[WRITE][risk=medium]' indicating a write operation with risk level, and explains empty list behavior. However, it does not disclose if the replace is atomic, requires permissions, or has immediate effect.

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 extremely concise: two lines with no wasted words. It front-loads the risk indication and directly states purpose, followed by a clear parameter definition.

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 simple tool with one parameter and no output schema, the description is largely complete. It covers parameter format, replace behavior, and empty list semantics. Minor gap: lack of contrast with set_model_denylist sibling.

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 is 0% (no description in schema), so description must compensate. It explains that models are 'Shell-glob patterns of permitted model names' with an example, adding significant meaning beyond the schema's array type.

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 verb 'Replace' and the resource 'model allowlist', specifying glob patterns and the behavior for empty list (allow-all). This distinguishes it from siblings like set_model_denylist.

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 usage for setting allowed models via glob patterns, but does not explicitly contrast with siblings like set_model_denylist or provide when-not-to-use guidance.

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