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

Annotations already indicate this is a non-read-only, non-idempotent, non-destructive write. The description adds meaningful context beyond that: it does not itself approve, it targets an existing human approval workflow, and organization-level MCP approval config plus business workflow approvals always apply. It does not disclose prerequisites such as budget state or 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?

The definition is short and front-loaded with the core action, followed by an important scope caveat and workflow context. No sentence is wasted, though the workflow-configuration sentence is somewhat peripheral.

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?

An output schema exists and annotations cover the safety profile, so the description does not need to explain return values. However, for a non-idempotent submission action it omits relevant state or preconditions, such as whether the budget must be in a specific status, and it gives no parameter guidance.

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 0%, so the schema provides only parameter names and formats without explanatory descriptions. The tool description mentions neither the required budgetId nor the optional data.notes field, leaving the agent to infer parameter meaning entirely from names and constraints.

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 states a specific verb and resource: submitting a budget into its existing human approval workflow. It also clarifies the key scope boundary ('This does not approve it'), which helps distinguish it from decide_budget_approval_request, though it does not name any sibling tool explicitly.

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 description implies this is the step before a human decision and that it should not be confused with an approval action. However, it does not explicitly say when to use this tool versus alternatives such as submit_budget_approval_request, decide_budget_approval_request, or cancel_budget_approval_request.

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