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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states 'Create' which implies a write/mutation operation, but doesn't address permissions, side effects (e.g., whether this affects existing cards), error conditions, or response format. This is inadequate for a tool with 13 parameters and no output schema.

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 action and resource. There's no wasted verbiage, making it easy to parse quickly.

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 complexity (13 parameters, mutation operation), lack of annotations, and no output schema, the description is insufficient. It doesn't explain behavioral aspects, parameter meanings, or usage context, leaving significant gaps for an agent to operate effectively.

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 low (23%), with only 3 of 13 parameters having descriptions. The description mentions 'Hero card with Code/Design/Art/Audio sub-cards', which hints at the purpose of some parameters (e.g., hero_deck, code_deck), but doesn't explain most parameters like 'owner', 'priority', 'effort', or 'allow_duplicate'. It fails to compensate for the schema's gaps.

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 ('Create') and the specific resource ('a Hero card with Code/Design/Art/Audio sub-cards'), making the purpose immediately understandable. However, it doesn't explicitly differentiate this tool from sibling tools like 'create_card' or 'split_features', which might also involve card creation or feature management.

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. It doesn't mention prerequisites, context (e.g., project planning phases), or comparisons to siblings like 'create_card' or 'split_features', leaving the agent to infer usage scenarios.

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