voicebox_update_story_item_times

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

Since no annotations exist, the description must disclose behavioral traits. It does not mention that the update is destructive (overwrites existing times), whether it is atomic, or any error handling. Output schema exists but its content is unknown, so the description should at least note that updates are applied immediately.

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?

Single sentence, zero waste. All words are meaningful and front-loaded.

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 tool with a JSON input and an output schema, the description could be sufficient but lacks context about validation, failure modes, or whether partial updates are allowed. The presence of an output schema somewhat reduces the need to explain return values, but the description should cover key behavioral aspects.

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 coverage is 100%, so the schema already documents both parameters. The description adds minimal value beyond the schema, only implying batch capability. Baseline 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 clearly states it performs batch updates of start/end times for story items, using specific verbs and resource names, and distinguishes from sibling tools like voicebox_edit_story_item (which likely updates other fields) and voicebox_reorder_story_items.

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?

No guidance on when to use this tool versus alternatives (e.g., voicebox_edit_story_item for single item time updates). The description does not mention prerequisites or exclusions.

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