spaces_add_item

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

With no annotations, the description carries the full burden of behavioral disclosure. It only states the action ('Add an item') without mentioning side effects, required permissions, failure modes, or what happens on success. Mutation behavior is implied but not elaborated.

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 front-loaded sentence with no fluff. While extremely concise, it lacks any structure to convey the additional context needed for a tool with 8 parameters, but it is appropriately small in size.

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 severely incomplete. It does not explain return values, required setup, default behavior, or the meaning of fields like assignee and priority. An agent would struggle to use it correctly without additional information.

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 100% of parameters with descriptions, so the description doesn't need to add parameter details. However, it doesn't highlight defaults or interdependencies (e.g., status defaults to the first bucket status). Baseline 3 applies.

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 uses 'Add' as a specific verb and identifies the resource as 'an item to a Spaces bucket', making the operation clear. It implicitly distinguishes from siblings like spaces_update_item and spaces_create_bucket, though it doesn't explicitly address the difference.

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 is given on when to use this tool versus alternatives such as spaces_update_item or spaces_create_bucket. There are no prerequisites, typical use cases, or exclusions mentioned.

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