rba_execute_file

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

With no annotations available, the description must disclose behavioral traits itself. It only mentions the two modes ('fire-and-forget' and 'structured results') but omits important behaviors like code execution side effects, permission requirements, client targeting implications, or error handling. The description adds minimal behavioral context beyond what the schema already encodes.

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 a single, dense sentence with no redundant text. It front-loads the primary action and efficiently conveys the two operation modes without wasting words.

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?

The tool has six parameters and no output schema, requiring a fairly detailed description for safe and effective use. The description fails to explain the 'target' selection semantics, 'timeoutMs' constraints, 'syntaxCheck' effect, or what 'structured results' actually include. The description is too terse for a tool of this complexity, leaving significant 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 0%, so the description is the sole source of parameter meaning. It does add clarity for 'mode' (send vs eval) and path (workspace file), but 'label', 'target', 'timeoutMs', and 'syntaxCheck' remain unexplained. The description only partially compensates for the missing schema descriptions.

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 clearly specifies the tool's function: 'Execute a workspace Lua file in Roblox', and distinguishes between two modes: 'fire-and-forget send' and 'eval with structured results'. This verb+resource+mode structure clearly sets it apart from sibling tools like rba_send_lua_file or rba_eval_lua_file.

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?

The description provides no guidance on when to choose this tool over siblings such as rba_send_lua_file, rba_eval_lua_file, or rba_execute_bundle. It does not state alternatives, exclusions, or prerequisites, leaving the agent to guess which tool to invoke for a given scenario.

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