Fire or invoke a RemoteEvent or RemoteFunction

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

With no annotations, the description carries the full burden. It does convey the side-effecting nature of the operation and the yield-vs-return distinction between InvokeServer and FireServer, but omits error behavior (e.g. missing remote), serialization constraints on arguments, and whether a live client session is required.

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, stating the action before the mode detail. It is efficient, though it is thin enough that the brevity reads as under-specification rather than disciplined concision.

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?

There is no output schema and no annotations, yet the description never explains what an invocation returns (the RemoteFunction result) or what happens on failure. For an action tool with zero structured behavioral coverage, this leaves meaningful gaps for 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 description coverage is 100%, so all three parameters are already documented in the schema, including the loadstring: convention and the isFunction yield semantics. The description only adds the generic phrase 'with custom arguments' and does not go beyond the schema, so the baseline 3 applies.

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 names a specific action (firing/invoking remotes) and distinguishes the two modes with the concrete API calls FireServer and InvokeServer. It is clear what the tool does, though it does not differentiate itself from adjacent siblings like ignore-remote or block-remote.

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 versus ignore-remote, block-remote, or the remote-spy tools, nor any prerequisite such as needing an active client (set-active-client). The agent is left to infer the whole usage context.

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