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

With no annotations, the description carries the full burden, and it does disclose two important behaviors: retry consumes credits, and items that don't fit the action are skipped and counted in 'skipped'. It does not cover permissions, whether 'remove' is reversible, or what null owner does at scale beyond the parenthetical.

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?

A single dense sentence, front-loaded with the action enumeration and followed by the skip-count behavior. Efficient with no filler, though the nested parentheticals make it slightly harder to parse.

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 5-parameter mutation tool with no annotations and no output schema, the description covers the action semantics, credit cost, and the 'skipped' output field reasonably well. It still leaves diligence_id undefined and says nothing about permissions or the irreversibility of 'remove'.

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%, so the description must compensate. It fully explains the action enum and the owner parameter (including null to clear), and implicitly covers reason via 'na' com reason and item_ids via 'vários itens'. diligence_id is never explained, leaving a required parameter undocumented in both schema and description.

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 a specific verb+resource — applying one action to many items — and enumerates the four supported actions with their meaning. It implicitly parallels the single-item siblings (assign_item, retry_item, mark_not_applicable, remove_item) by referencing 'owner como em assign_item', but never explicitly contrasts bulk vs single-item use.

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?

Usage is implied through the action enumeration: the agent can infer which action value maps to which intent. However, there is no explicit 'use this when acting on many items, use X for a single item', and no statement of prerequisites or when-not-to-use.

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