gc_local_model

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

No annotations are provided, so the description carries the full burden. It mentions provisioning and offline operation, which implies state-changing behavior, but doesn't disclose side effects, prerequisites (e.g., does provisioning require an existing model file?), or whether these operations persist state. The mention of 'Story 2.10, AD-34' adds no behavioral information.

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 very compact - two sentences listing the action enum. It's efficient with no wasted prose. However, the second action list is fairly redundant with the schema enum, since it duplicates what the input schema already declares.

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 4-action dispatcher with no output schema and no annotations, the description is under-specified. It doesn't explain return values, error behavior, or how actions interact with each other. Each action behaves differently, yet the description treats them uniformly. The 'Story 2.10, AD-34' reference is opaque to an agent.

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 100%, so the schema documents all three parameters. The description adds minimal param context beyond noting model and endpoint are 'for provision' through the inline parenthetical. It doesn't explain what each action expects in terms of parameters (does status require model? does connectivity require endpoint?), which is a significant gap for a multi-action dispatcher.

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 states it handles local MLX model provisioning and offline operation status, which is clear enough as a purpose. However, it's a multi-action dispatcher (four distinct actions) rather than a single-focused verb+resource, so it's more a category description than a specific operation. It does distinguish from siblings via the MLX model scope.

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?

There is no guidance on when to use this tool vs alternatives. It lists four actions (provision, status, offline, connectivity) but doesn't explain when each would be appropriate, nor does it mention any exclusions or alternatives. The sibling set includes many gc_* tools where such guidance would be crucial.

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