Budget Set Budget Amount

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

Annotations already indicate readOnlyHint=false, so the description's statement 'may create or update' adds no new behavioral insight. No additional effects (e.g., idempotency, side effects on existing budgets) are disclosed beyond the annotations.

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 description is very short (two sentences), which is concise, but it is overly minimal given the tool's complexity. It lacks substance needed for effective agent usage, so while brief, it is not appropriately informative.

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?

Given the high parameter count, low schema coverage, absence of output schema, and many sibling tools, the description is severely incomplete. It does not cover return values, parameter details, or usage context, leaving the agent with insufficient information.

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?

With schema description coverage at only 25%, the description does not compensate by explaining any of the 8 parameters. It provides no meaning beyond the bare schema names, which is insufficient for an agent to correctly set parameters like 'fields', 'session_path', or 'apply_to_future'.

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 the verb 'Set budget amount' which matches the tool name and title, but it fails to differentiate from sibling tools like budget_set_budget_group_amount. The phrase 'create or update Monarch data' adds minimal context and does not specify which budget entity is being set (e.g., monthly category budget).

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?

No guidance is provided on when to use this tool versus alternatives such as budget_set_budget_group_amount or budget_create_budget. The description lacks any context for selection, leaving the agent without direction.

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