sync_config

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

With no annotations, the description carries the full burden; it does disclose the key traits of idempotency and that it mutates the game's Luau config file, which is valuable. It omits what happens on partial failure, whether existing config content is preserved or overwritten, permission/auth requirements, and what is returned after creation.

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?

Short and front-loaded: the core action and idempotency come first, with the input-mode and dryRun notes following. Each sentence carries content, though the phrasing is clipped to the point of underspecifying the alternative input path.

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?

For a 7-parameter mutation tool with no annotations and no output schema, the description is thin: it never explains default config location, how items and specPath interact if both are given, or what the caller gets back after IDs are written.

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 must compensate, and it only covers specPath, dryRun, and vaguely "fields inline." Four parameters (passTable, productTable, configPath, universeId) and the required-key structure of items (key/kind/name/price) receive no explanation anywhere.

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?

States specific verbs and resources: create missing passes/products and write their IDs into the Luau config. This distinguishes it from the pure-creation siblings by its sync/ID-writeback scope, though it doesn't explicitly name create_game_pass or create_developer_product as the single-item alternatives.

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?

Gives a useful operating hint ("Use dryRun first") and a choice of input modes (specPath or inline fields), but never states when to prefer this bulk sync over the sibling create_game_pass/create_developer_product tools, or what preconditions (e.g., existing config file) are needed.

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