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

The description describes removing/deleting a budget, yet the annotations declare destructiveHint: false, sending opposite signals on the central question of whether invoking this tool destroys anything. Beyond the bulk note, no idempotency behavior, error handling, or reversibility is disclosed, and idempotentHint is false. This is an annotation contradiction.

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?

Two short sentences with the core purpose front-loaded and the bulk capability following; no filler or repetition. The Portuguese-only description amid English sibling names is a minor structural weakness but does not hurt scannability.

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?

For a delete tool with no output schema and 0% parameter coverage, the definition omits success/error behavior, what happens when budget_id doesn't exist, and the relationship between the two parameters. The annotation contradiction leaves the side-effect profile unresolved, so an agent cannot confidently predict consequences.

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 description bears the responsibility of defining the parameters; it only states that budget_ids enables 'batched execution,' leaving budget_id's meaning to inference from the tool name. It doesn't clarify whether budget_id and budget_ids are mutually exclusive, optional together, or how batch failures are reported.

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 uses a specific verb ('Remove') tied to a concrete resource — 'um orçamento (limite de gastos) de uma categoria' — clarifying the domain meaning of a budget as a category spending limit. Within the budget-related sibling set (create_budget, update_budget, clone_budgets, list_budgets), the delete intent is unambiguous. It doesn't explicitly contrast with update_budget, which keeps it from a 5.

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?

There is no guidance on when to use this tool versus siblings like organizze_update_budget (adjust an existing limit) or organizze_clone_budgets (copy budgets). The bulk-support sentence explains how to batch calls, not when this tool is the right choice; no exclusions or alternatives are mentioned.

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