set_budget

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

With no annotations, the description carries full burden. It explains when alerts and CI failures trigger based on alert_at_pct and block_at_pct, and scope usage. But it lacks details on update behavior (merge or replace), required permissions, rate limits, or reversibility.

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?

Well-structured with a clear intro, parameter list, and examples. Every sentence adds value; no fluff. Front-loaded purpose.

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 7 parameters and no output schema, the description is fairly comprehensive with parameter details and examples. Missing update behavior details and return value info, but overall adequate.

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 coverage is 0%, yet the description provides thorough explanations for all 7 parameters in the Args section, including default values and scope_value usage (e.g., '*' for total account). Examples further clarify parameter meaning.

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 clearly states 'Create or update a spending budget' with specifics on what budgets do (fire Slack alerts and fail CI checks). It distinguishes itself from siblings like list_budgets, delete_budget, or check_budget_status.

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?

Examples provide context on when to use the tool (e.g., 'Set a $50,000 monthly budget for AWS'). However, it does not explicitly mention alternatives like sync_budgets_from_yaml for bulk setup or when not to use it.

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