updateDenylistEntry

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

No annotations are provided, so the description carries the full burden. It mentions updating and enabling/disabling but does not specify if the entry must exist, what happens on failure, or any side effects. The safety note hints at destructiveness but is insufficient.

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 two sentences, directly stating purpose and a safety warning. No unnecessary words; information is front-loaded and efficient.

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?

Given the large number of sibling tools related to denylist management, the description does not clarify how this update tool differs from add/remove/replace counterparts. It also lacks details about return values or error handling, leaving gaps for an agent.

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 100%, so parameters are already described. The description adds 'enable/disable' which aligns with the 'active' parameter but does not provide significant additional meaning beyond the schema.

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 it updates properties of a denylist entry with an example of enable/disable. This is specific and distinguishes from siblings like addToDenylist or removeFromDenylist, though it does not explicitly exclude other operations.

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 safety note provides a usage constraint (test profiles only), but there is no guidance on when to use update versus sibling tools like addToDenylist or removeFromDenylist, leaving some ambiguity.

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