score_checklist_item

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 implies a mutation (scoring/marking), but doesn't specify whether this is a toggle, requires permissions, has side effects (e.g., affecting task completion), or what the response looks like. For a mutation 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 very concise with a single phrase, making it front-loaded and efficient. However, it borders on under-specification, as it could benefit from slightly more detail to clarify the action without becoming verbose.

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 mutation tool with no annotations and no output schema, the description is incomplete. It lacks details on behavioral traits (e.g., how scoring works, error conditions), doesn't explain return values, and provides minimal context beyond the basic action, making it inadequate for full agent understanding.

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 schema description coverage is 100%, with clear descriptions for 'taskId' and 'itemId' in the input schema. The description adds no additional parameter semantics beyond what the schema provides, such as format examples or relationships between parameters. Given the high schema coverage, the baseline score of 3 is appropriate.

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 'Score checklist item (mark complete/incomplete)' states the action (score/mark) and target (checklist item), which clarifies the basic purpose. However, it's somewhat vague about what 'score' specifically means in this context (e.g., is it toggling status, setting a specific value?), and it doesn't distinguish this tool from sibling tools like 'score_task' or 'update_checklist_item', which might have overlapping functionality.

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 (e.g., needing an existing checklist item), exclusions, or how it differs from similar tools like 'score_task' or 'update_checklist_item', leaving the agent to infer usage from the name alone.

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