Create a Bucket

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

Annotations provide readOnlyHint=false and destructiveHint=false, so the write nature is clear. The description adds the semantic detail that a bucket is a column, but it doesn't disclose additional behavioral traits such as duplicate name handling or side effects beyond what annotations already signal.

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 that contains no fluff. It succinctly conveys the core action and target.

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 simple create tool with two clearly documented parameters, the description is adequate. It clarifies the domain-specific term 'bucket' as a column. No output schema exists, but the description doesn't need to detail returns for such a straightforward operation. Minor gap: no mention of return value or potential errors, but not critical.

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 100% (both plan_id and name have descriptions). The description itself doesn't add parameter-level detail beyond the schema, so the baseline of 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 a specific verb and resource: 'Create a new bucket (column) in a plan.' It clearly states what the tool does and distinguishes it from sibling tools like planner_create_task by explicitly referencing 'bucket' and clarifying it as a column within a plan.

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 implies usage when you need to add a bucket to a plan, but it doesn't explicitly contrast with alternatives or state when not to use it. The sibling list shows other creation tools (e.g., planner_create_task), but no explicit differentiation is provided.

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