merge_adapter

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

Annotations already declare destructiveHint=false and openWorldHint=false, so safety is covered; the description usefully adds that the base and adapter are preserved and a new model is created. However, "Launch" strongly implies an asynchronous job, and the description never says whether it returns a job handle requiring job_status/cancel_job follow-up, nor anything about cost, GPU/device requirements, or failure modes.

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?

A single front-loaded sentence with no filler; the operation and its key invariant (preserve inputs) are both stated up front.

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?

An output schema exists, so return-value explanation is not needed, and the core operation plus non-destructive guarantee are stated. What remains missing is the async/job-lifecycle context and the semantics of dtype/device, which matter for correct invocation of a launch-style 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?

Schema description coverage is 0% for a nested request object with five fields, so the description carries the burden and only partially compensates: it implies model (base), adapter, and output (new standalone model), but says nothing about the dtype and device options, their defaults, or the name-pattern constraints enforced by the 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?

"Launch a LoRA merge into a new standalone model" gives a specific verb (launch/merge) and a specific resource (LoRA adapter + base model -> new standalone model), which distinguishes it from fine-tuning (start_fine_tune) and weight editing (apply_weight_edits). It stops short of explicitly contrasting with those siblings, so it is clear but not fully differentiated.

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?

Usage is only implied: an agent can infer this is the tool for combining an existing base model and adapter into a permanent artifact, but there is no explicit when-to-use, when-not-to-use, or prerequisite (e.g. both inputs must already exist in inventory). No alternative tool is named.

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