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

The annotations already show readOnlyHint=false and destructiveHint=false, so the important read/write and safety traits are given. The description adds essentially only 'bulk support', but it does not disclose behavior around unsafe, account, what happens when the label is absent, or how the note association may be affected.

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 contains only two short sentences, both useful and front-loaded. The action, target, label semantics, and bulk support are communicated without filler, so every sentence earns its place.

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 the simplest invocation, the description is sufficient: a note_id and a label by name can be supplied to remove the label. It is less complete for batch and edge cases, especially because unsafe and account are unexplained and there are no output shapes or error/behavioral expectations disclosed.

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%, and the description compensates only partly: it clarifies that label is matched by name and that note_ids enables bulk execution. It leaves unsafe and account undefined, and the relationship between required note_id and optional note_ids is ambiguous from the provided text.

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 and target: "Remove uma label (por nome) de uma nota" clearly states that it removes a label by name from a note. The bulk note about note_ids adds scope and distinguishes it from singular add/delete label operations, and the action is clearly differentiated from sibling tools like keep_add_label_to_note and keep_delete_label.

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?

The description gives a clear use context for removing labels from notes and adds a useful batch-use hint with note_ids. However, it does not explicitly say when not to use it, does not mention alternatives, and does not state any prerequisites or constraints such as account requirements.

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