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

With no annotations provided, the description must disclose behavioral traits on its own. It only states the action 'renames a column' without mentioning side effects, permissions, error conditions, or whether the operation is reversible. This is minimal transparency for a mutation tool.

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 a single, compact sentence with no filler or redundant information. It is front-loaded with the core action and resource, making it highly efficient.

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?

The tool has no annotations, no output schema, and low schema coverage. The description is too terse to provide sufficient context: it omits what the parameters mean, how the rename affects the board, and any operational details. A simple rename still requires more explanation to be used 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?

The schema has low description coverage (33%), with only 'column' having any explanation ('current name or ID'). The description fails to clarify the roles of 'board_id' or 'new_name', and does not compensate for the schema's gaps. For a tool with three required parameters, this is a significant omission.

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 'Benennt eine Spalte um' (Renames a column) uses a specific verb (rename) and resource (column), making the tool's purpose immediately clear. It distinguishes from siblings like update_card or add_column, as no other tool explicitly handles renaming.

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?

No guidance is provided about when to use this tool versus alternatives. There is no mention of prerequisites, such as needing an existing column, or when to prefer rename_column over update_board or other tools. The description gives no contextual usage clues.

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