outlook_reply_all

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

No annotations are provided, so the description must carry the full behavioral burden, and it does not. It omits whether the reply is sent immediately or drafted, how the target message is identified given zero parameters, and whether recipients are auto-populated.

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?

A single, front-loaded sentence with no filler. It is efficient, though it is arguably too terse given the behavioral gaps.

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 messaging action with no annotations, no output schema, and no parameters, the description should explain the invocation context (selected email, body source) and the send-vs-draft behavior. Almost none of that is covered.

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?

Zero parameters means there is nothing to document in the schema (baseline 4), but the description does not compensate by explaining how the tool resolves which email to reply to or where the reply body comes from. That omission is meaningful for a zero-parameter action tool.

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?

Clear specific verb ('Replies') and resource ('Outlook email') with a scope qualifier ('all recipients') that separates it from outlook_reply_email. It does not explicitly name the sibling, but the distinction is inferable from the description alone.

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 when-to-use or when-not-to-use guidance is given, and no alternatives are named. The description never states the precondition (an email must already be selected/identified) required to invoke a reply-all.

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