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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=false. The description adds useful behavioral detail that updates are partial and support bulk execution via ids, but it does not clarify mutation effects, required permissions, or response behavior. There is no 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?

The description is short and front-loads the core operation before bulk support. It is structurally efficient, though the field list is not aligned with the schema and therefore creates avoidable confusion.

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?

This is a mutation tool with six parameters, a nested extra object, no output schema, and minimal annotations. The description covers the general update intent and bulk mode, but it fails to document the actual schema parameters and gives incorrect field names, leaving the agent without enough reliable information to call it correctly.

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 must carry parameter meaning, but it lists fields that do not exist in the schema (amount, date_due, date_payment, description, entry_type, categories_id) and omits actual parameters such as value, status, extra, and due_date. Only id and ids are meaningfully covered. This is misleading for invocation.

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 a specific verb and resource: updates a transaction by ID. It distinguishes the operation from create/get/list siblings, though it does not explicitly contrast alternatives. The purpose is clear despite the later parameter inconsistencies.

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?

It gives partial usage guidance: send only fields to change, and use ids for batched execution. However, it does not explain when to choose this tool over siblings like advbox_get_transaction or advbox_create_transaction, nor does it state preconditions or exclusions.

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