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

With no annotations, the description carries the burden, and it does convey that this gates a 'high-impact action' and that the decision is binary. However, it omits what happens to the action on 'no', whether a pending confirmation expires, and what permissions are needed to approve. Useful context, but not the full behavioral picture for an approval-mutation tool.

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?

Two tight sentences with the action and its trigger front-loaded, then the invocation mechanics. Nothing extraneous and nothing buried.

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?

Covers the essential flow an agent needs for a confirmation tool with no output schema, and the schema fully fills in the workspace/token details the description skips. Only edge-case behavior (what declining does, confirmation lifetime) is left implicit.

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 the schema already documents message_id, the yes/no enum, workspace_id, and token precedence. The description only restates that message_id comes from the confirmation request and that decision is 'yes' or 'no', adding little beyond the schema's own text. Baseline 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?

Names a specific verb pair (approve/decline) and the exact resource (a confirmation request) it acts on. It also identifies the originating siblings (autowhisper_cmo, autowhisper_action), so an agent can distinguish this from the tools that raise the request.

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?

States the selecting condition clearly: use this when the CMO or autowhisper_action asked you to confirm a high-impact action, passing the message_id it supplied. There are no explicit exclusions or named alternatives, but the trigger is unambiguous enough to route correctly.

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