live_setup_system

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 disclosing side effects. It only says 'Generate live update system' without explaining whether it writes files to the directory, requires an API key, prompts for input, creates a project scaffold, or modifies existing code. Behaviorally, this is a black box.

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 one sentence and technically short, but this is under-specification rather than conciseness. It provides no useful information that isn't already inferable from the name, so the brevity does not earn a higher score.

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 annotations, no output schema, minimal parameter docs, and a two-parameter schema, the description is not complete enough for an agent to select or invoke the tool correctly. It lacks any context about what the generated system includes, how it is configured, or what the agent should expect as a result.

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 only 50% and api_key is undocumented in the schema. The description does not mention either parameter, so it adds no meaning beyond the schema. An agent cannot tell what 'directory' should point to or why api_key is optional.

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 'Generate live update system' is essentially a restatement of the tool name and provides no concrete definition of what a 'live update system' is, what files or artifacts are generated, or what technology it targets. It has a verb and resource but the resource is vague, so it doesn't clearly distinguish the tool from siblings like live_add_optimistic or live_add_conflict.

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 about when to use this tool, what the generated system is for, or how it relates to sibling tools such as live_add_optimistic and live_add_conflict. An agent has no way to know whether this is a prerequisite, an alternative, or a standalone operation.

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