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

No annotations are supplied, so the description carries the full burden. It usefully discloses sort order and recency ('sorted by creation time', 'recent orders'), but says nothing about pagination, how to retrieve older orders, authorization requirements, or whether limit truncation silently drops results.

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 core action and followed by return behavior. No filler, though the second sentence partly overlaps the first by restating that results are recent orders.

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 must convey return shape; it gives sort order and recency but omits pagination semantics, ordering direction, and what fields an order contains. For a simple two-parameter list tool this is adequate but not complete.

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 both limit and status are already documented with bounds, defaults, and an enum. The description only restates the status filter and adds no syntax, default, or interaction detail beyond the schema, which is the baseline case.

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?

The description names a specific verb and resource ('Get your order history') and states the scope is history rather than a single order. However, it never distinguishes itself from the sibling get_order_status, so an agent must infer which one returns a list versus a single record.

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?

The phrase 'with optional status filter' implies the main use case (browse recent orders, optionally narrowed by status), but there is no explicit when-to-use rule and no mention of when to prefer get_order_status or get_auto_action_history instead.

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