live_add_optimistic

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 behavioral disclosure. It only implies a mutation via 'Add' but discloses nothing about side effects: what files get modified, whether api_key triggers network calls, whether the operation is reversible, or what happens on failure. For a tool that clearly needs safe-guarding context, this is a significant gap.

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 three words and front-loaded in the sense that there's nothing else to read. But this is under-specification rather than genuine conciseness: it omits essential semantic content (domain, parameters, behavior), so the brevity harms rather than helps.

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 and no output schema, the description must be self-sufficient, and it is not. An agent cannot determine what optimistic updates are, what api_key is for, where directory should point, or how this differs from the closely related live_add_conflict tool. The minimal signature and ample sibling context make this incompleteness especially costly.

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 50%: 'directory' is documented as 'Project directory', but 'api_key' has no schema description. The tool description adds nothing about either parameter — it doesn't explain what api_key authenticates or how directory relates to adding optimistic updates. The description fails to compensate for the undocumented parameter.

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 does state a verb ('Add') and a resource ('optimistic updates'), so it conveys the general intent at a high level. However, it is vague: it never explains what an 'optimistic update' means in this domain, what system it applies to (the 'live' context), or how it differs from siblings like live_setup_system and live_add_conflict. It barely adds information beyond the tool name itself.

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 versus alternatives. It doesn't mention live_add_conflict or live_setup_system, doesn't state prerequisites (e.g., needing a live system already set up), and gives no exclusions. An agent has no way to know if this is the right tool for the task.

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