A3.7/5.0
Behavior4/5

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

Annotations already mark this destructive and idempotent; the description adds useful specificity by stating that any existing rules are replaced. It does not go as far as noting the conditional confirm requirement, but the schema covers that, so the added behavioral insight is sufficient for a scoring of 4.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences with the key action and destructive effect front-loaded. No filler or redundant restating of the schema.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Adequate for a clear mutating operation with detailed schema and annotations, but it omits when-to-use guidance and the confirm/destructive-policy context that would make it fully self-contained, especially given the absence of an output schema describing the result.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds only a webhook hint and the replacement consequence; it does not explain bucketId, confirm, or rule construction. With schema description coverage at 67% and rich per-property documentation in the schema, the description neither meaningfully compensates nor detracts from what the agent can already read.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific operation: setting event notification webhook rules for a B2 bucket, and adds the non-obvious behavior that existing rules are replaced. This distinguishes it from sibling b2_get_bucket_notification_rules without needing to open the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool vs alternatives, no prerequisites, and no mention that b2_get_bucket_notification_rules is the read counterpart. The description only states what the tool does, leaving the agent to infer selection context.

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