search_modpacks

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

With no annotations, the description carries the full burden. It adds useful context about the embedded CurseForge API key and the return type, but does not explicitly state read-only behavior, rate limits, pagination, or default limits. The 'search' verb implies no side effects, but this is not explicitly disclosed.

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 two sentences, front-loaded with the main verb, and includes only essential details. Every sentence contributes value without redundancy.

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 description covers the return value shape (ModpackSummary[] with fields) and the special API key detail, which is important context. However, it omits default source/limit, pagination, and error scenarios. For a search tool with no output schema, this is mostly complete but missing some operational details.

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 should compensate for parameter meanings. It indirectly explains the 'source' parameter by naming Modrinth and CurseForge, but does not mention 'query' or 'limit' at all, leaving two of three parameters unexplained beyond the schema.

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 starts with a specific verb 'Search' and resource 'modpacks', and clearly distinguishes from siblings by specifying the repositories (Modrinth/CurseForge). It differentiates from list_modpacks and get_modpack by focusing on search behavior and return type.

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 clearly indicates the tool's purpose (searching modpacks) and context (HMCL repositories), implying when to use it. However, it does not explicitly contrast with alternative tools like list_modpacks or get_modpack, nor state when not to use it.

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