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

Annotations only cover idempotency and open-world scope, so the description carries most of the behavioral burden. It discloses a genuinely non-obvious trait: when the provider's API cannot flip the hold (Printful today), the call is deferred and returns a dashboard_url, with the hold remaining active until the provider's release fires. Minor gap: no statement about required permissions.

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 front-loaded sentences that lead with the action and then the fallback behavior; no filler. The trailing '[#7b5295]' artifact is stray noise that slightly detracts from otherwise tight prose.

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?

With no output schema, the description correctly compensates by explaining the deferred-result shape (dashboard_url) an agent should expect. For a 3-param mutation tool this covers what's needed, though the absence of any permission or failure-mode guidance leaves a small gap.

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 description coverage is 100%, so all three parameters (hold_uuid, order_uuid, workspace) are already documented in the schema. The description's note that hold_uuid comes from list_order_holds restates what the schema already says, adding no new semantics — 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?

States a specific verb and resource ('Approve a design-approval hold on an order') plus the downstream effect ('so the provider can proceed'). This cleanly separates it from sibling tools like approve_order, hold_order, and request_hold_changes.

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?

It tells the agent where to source the identifier ('Get the hold_uuid from list_order_holds'), which is a useful routing hint. However, it never states when to prefer this over approve_order or unapprove_order, nor any preconditions; usage is implied rather than spelled out.

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