update_cluster_firewall_rule

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

No annotations are provided, and the description lacks critical behavioral traits. It does not disclose whether updates are incremental or full replacements, what happens on error, or any side effects. For a mutation tool, this is a major gap.

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 lengthy parameter list without a concise summary. It lacks structured formatting (e.g., bullet points or sections) and includes unnecessary repetition (e.g., 'pos' mentioned twice). Not appropriately sized for a tool with 12 parameters.

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?

Despite having an output schema, the description does not explain the return value or behavior (e.g., whether it returns the updated rule). It covers parameter meanings but misses operational context like idempotency or required permissions. Incomplete for a complex tool.

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%, but the description provides detailed explanations for all 12 parameters, including possible values for 'action' and format for 'delete'. This significantly adds value beyond the bare schema, though some parameters like 'enable' could be clarified further.

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 'Update a cluster-level firewall rule' with a specific verb and resource. It is distinct from sibling tools like create_cluster_firewall_rule and delete_cluster_firewall_rule, providing clear differentiation.

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. It does not mention prerequisites (e.g., rule must exist) or scenarios where delete or create would be more appropriate. No explicit when-to-use or when-not-to-use context.

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