approve_queued_email

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

With no annotations, the description carries the full burden and does disclose key traits: this is an irreversible-ish mutation (draft creation or actual send), it is gated on explicit user approval, and the draft becomes 'visible'. It omits whether send can be blocked by send policy or what it returns, so it is strong but not exhaustive.

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 short sentences, front-loaded with the action and followed by the precondition. Every clause earns its place with no filler.

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?

No output schema or annotations exist, so the description must stand alone; it covers the action, the gate, and the two delivery outcomes adequately. It stops short of describing the return payload or failure modes, which an agent calling a send path would benefit from.

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 67% and the enum on 'delivery' is documented in the schema itself. The description only restates that the item and delivery mode must match the approved one, adding no syntax or format detail beyond the schema. Baseline 3 is appropriate.

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?

States a specific verb and resource ('turn one pending approval-queue item into a visible draft or send it') and constrains the unit of work to exactly one item. It clearly differentiates from siblings like queue_email_for_approval and discard_queued_email by describing the approval-outcome action.

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?

Gives an explicit precondition: only call after the user explicitly approved this exact item and delivery mode. It does not name an alternative sibling for the not-yet-approved or rejection case, but the when-to-use gate is unambiguous.

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