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

Annotations already flag destructiveHint=true and idempotentHint=false, and the description adds substantial value beyond them: the change is gated on human approval of the exact request, requires execute_approved_action afterward, and organizational approval policy is administrator-configurable. That is real workflow context an agent cannot get from the annotations. It stops short of saying whether the update overwrites omitted fields or how rejection surfaces.

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?

Five short sentences, with the approval gating placed early enough to inform the decision. The generic 'Use this when working with RetailHardHat budgets records' opener is boilerplate that could be cut without loss.

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, so return values need not be explained, and the approval workflow is well covered. However, for a three-parameter mutation with a nested, entirely undescribed data object, the description leaves the agent guessing what a valid update payload looks like.

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% – the nested data fields are documented only as 'notes', 'category', 'description', 'planned Amount', and plannedAmount is typed as a string with no format guidance. The description adds no information about any of the three required parameters, so it fails to compensate for the coverage gap.

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 ('Update a project budget item') that an agent can match against the sibling create_project_budget_item and delete_project_budget_item. The opening clause about 'RetailHardHat budgets records' adds little, and the description never distinguishes this from adjacent tools like update_budget_line_item or update_project_budget_template_item.

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?

'Use this when working with RetailHardHat budgets records in the connected organization' gestures at context but does not tell the agent when to pick this over the many siblings. The approval-flow sentences clarify a precondition for use, but no alternatives or exclusions are named.

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