get_all_spell_lists

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states this is a 'get' operation for reference, implying read-only behavior, but doesn't clarify aspects like rate limits, authentication needs, or what 'quick reference' entails (e.g., format, pagination). For a tool with zero annotation coverage, this is a significant gap in transparency.

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, efficient sentence that front-loads the core purpose ('Get all available D&D 5E spell lists') and adds a brief usage note ('for quick reference'). There is no wasted text, and every word contributes to understanding the tool's intent.

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 has no parameters, no annotations, and no output schema, the description is minimally adequate. It explains what the tool does but lacks details on behavioral traits (e.g., response format, limitations) and doesn't leverage context from siblings. For a simple read operation, this is passable but leaves gaps in completeness.

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 tool has 0 parameters, and schema description coverage is 100% (though empty). The description doesn't need to add parameter details, and it appropriately avoids redundancy. A baseline of 4 is applied for zero-parameter tools, as no compensation is needed 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 clearly states the verb ('Get') and resource ('all available D&D 5E spell lists'), making the purpose specific and understandable. However, it doesn't explicitly differentiate from sibling tools like 'get_spell_list_details' or 'search_spell_lists', which would require more specific scope or usage context to earn a 5.

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 like 'get_spell_list_details' (for specific lists) or 'search_spell_lists' (for filtered searches). It implies usage for 'quick reference' but lacks explicit when/when-not instructions or named alternatives, leaving the agent to infer context.

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