Overwing

Load the starter workflow (Overwing Tower)

tower_load_template
Idempotent

Set up Overwing Tower for this organization by loading the starter workflow: email purchase order to order entry, with create_order, update_order and cancel_order against a mock IBM i system, and a starter policy. Idempotent. Needs an organization key. Returns a sample input you can submit. Next: tower_create_agent.

A4.3/5.0
Behavior4/5

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

Annotations declare readOnlyHint=false and idempotentHint=true; the description restates idempotency (consistent, no contradiction) and adds meaningful extra context: the exact artifacts created, the environment it touches ('mock IBM i system'), the auth precondition ('Needs an organization key'), and the return value ('Returns a sample input you can submit'). No annotation contradiction, and it goes beyond what annotations provide.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the setup purpose, then the concrete contents, the idempotency/auth notes, and finally the next step. Dense but each clause earns its place. The single long appositive sentence listing the workflow contents is slightly heavy, keeping it just under a 5.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-param setup tool with no output schema, the description covers what is created, the auth precondition, idempotency, and the return value, plus the natural next tool. Little an agent needs to invoke it correctly is missing, though a note on behavior when the org is already set up would complete it.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Zero parameters, so per the baseline rule this is a 4. The description does hint at an out-of-band input ('Needs an organization key') that is not represented in the schema, which is useful context even though there is nothing to document parameter-wise.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a concrete verb and resource ('Set up Overwing Tower... by loading the starter workflow') and enumerates exactly what is provisioned: email-po-to-order entry, three specific tools (create_order, update_order, cancel_order) against a mock IBM i system, and a starter policy. This is far more specific than its siblings and lets an agent recognize it as the bootstrap/setup entry point.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives real contextual guidance: it operates 'for this organization', 'Needs an organization key', and explicitly routes forward with 'Next: tower_create_agent'. It does not state when NOT to use it (e.g., against an already-configured org other than via idempotency), so it falls short of a full 5, but the when/where and next-step are clear.

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