update_customformat_bulk

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

The annotations already provide idempotentHint=true and destructiveHint=false, but the description adds little behavioral context beyond saying it updates. It does not disclose whether the bulk operation is all-or-nothing, how partial failures are handled, or whether missing fields are overwritten.

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 short and front-loads the operation and endpoint. The 'Args' block is minimal and earns its place by pointing to the schema. Slightly more explicit wording like 'bulk update' would improve it, but there is no wasted text.

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 bulk mutation with an open body object, the description tells the agent where to find field definitions, and an output schema exists to describe return data. Still, it omits important context about validation, error behavior, and how the bulk update interacts with existing custom formats.

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 0% and body is an opaque additionalProperties object. The description adds the useful directive to read the matching GET or /schema endpoint to discover expected fields, which is the main semantic guidance available to the agent. It stops short of documenting any actual body structure.

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 states the operation 'Update CustomFormat' and provides the endpoint 'PUT /api/v3/customformat/bulk', which identifies both the resource and that this is the bulk variant. However, it does not explicitly say 'bulk update', leaving some differentiation from update_customformat_by_id implicit.

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 about when to use this bulk endpoint versus the sibling update_customformat_by_id, nor any preconditions such as existing records or required IDs. The instruction to read the GET/schema endpoint is useful but does not address tool selection or exclusions.

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