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

Annotations already declare a write, open-world operation (readOnlyHint=false, openWorldHint=true), and the description adds real context beyond them: it reaches the client, involves money, requires an API key with app access, and notes the per-call confirmation is on by default but can be switched off. It stops short of describing what state changes on release or whether it is reversible.

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?

The leading 'Buildertrend:' prefix and the 'approve or decline in their portal' clause are restated twice, padding an otherwise front-loaded description. Every sentence is useful but several repeat the same point.

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?

Covers the key facts for a mutation tool with no output schema: external client reach, financial impact, confirmation policy, API key requirement, and where to check the resulting decision. It lacks only the mutation's side effects/irreversibility detail.

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 change_order_id and message are already documented in the schema. The description does not add format, sourcing, or constraint detail beyond the schema, so the 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 (release/send) plus the resource (change order) and its effect: the client approves or declines it in the portal. This clearly separates it from sibling buildertrend_create_change_order (creation) and buildertrend_list_change_orders (read), so an agent can route without opening the schema.

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?

Explicitly routes status-checking to list_change_orders and states the confirmation precondition ('confirm with the user before each call'). It gives clear context for when to call, though it never states when NOT to release a change order.

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