get_node_pack_details

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

With no annotations provided, the description bears the full burden of behavioral disclosure. It does not state whether the operation is read-only, requires authentication, has rate limits, or what errors may occur. The phrase 'from the Registry' hints at a network call but lacks sufficient detail for an agent to anticipate behavior.

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 concise sentence. It is front-loaded with the action and resource, and every word contributes meaning. No extraneous information is present.

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 lack of output schema and annotations, the description is incomplete. It does not explain what 'detailed information' entails (e.g., attributes of the node pack), error responses, or pagination. An agent cannot fully understand the tool's behavior or output from this description alone.

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?

The input schema covers the single parameter 'id' with a description and example. Since schema description coverage is 100%, the description adds no extra semantics. The tool description's mention of 'specific ComfyUI custom node pack' aligns with the parameter but does not elaborate on format or constraints beyond what the schema already provides.

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 ('get detailed information'), the resource ('ComfyUI custom node pack'), and the source ('from the Registry'). It distinguishes itself from sibling tools like 'get_node_info' (which likely targets individual nodes) and 'search_custom_nodes' (which is for searching, not fetching details).

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 use this tool versus alternatives. For example, it does not indicate whether to first search for node packs using 'search_custom_nodes' or whether this tool complements 'get_node_info'. No when-not-to-use or prerequisite information is included.

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