Roblox Set Script Source

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

With no annotations, the description bears the full burden. It describes the destructive action of replacing source code but does not disclose whether changes are reversible, if the script is automatically saved, or if events are triggered. No mention of permissions or error handling.

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, front-loaded sentence that conveys the essential action and target with no extraneous words. It earns its place efficiently.

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?

Given the tool's moderate complexity (3 params, no output schema, no annotations), the description should clarify return behavior, potential errors, or side effects. It does not mention whether the tool returns a success indicator or waits for confirmation, leaving gaps for the 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 coverage is 100% for the three parameters, each having a description in the schema. The tool description reiterates the overall purpose but adds no new meaning for individual parameters beyond what the schema already provides. Baseline 3 is appropriate.

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 states the action ('Replace the entire source code') and specifies the resource types (Script, LocalScript, ModuleScript) and the environment (Roblox Studio). It effectively distinguishes from siblings like roblox_get_script_source and roblox_edit_script_lines.

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 lacks guidance on when to use this tool versus alternatives (e.g., roblox_edit_script_lines for partial edits, roblox_inject_code). It does not mention prerequisites like script existence or path validity, and omits context such as side effects or limitations.

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