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

With no annotations provided, the description carries full burden for behavioral disclosure. While 'rename' implies a mutation operation, the description doesn't address permission requirements, whether the rename affects existing references to the column, potential rate limits, or error conditions. The description states what the tool does but not how it behaves beyond the basic operation.

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 well-structured with clear sections (purpose, args, returns) and uses minimal words to convey essential information. The front-loaded purpose statement is efficient, though the Args/Returns formatting is more documentation-style than natural language guidance.

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 mutation tool with 3 parameters, 0% schema coverage, no annotations, but with an output schema, the description covers the basic operation and parameters adequately. However, it lacks important context about permissions, side effects, and error handling that would be valuable for an agent invoking this mutation operation on a critical resource like a column.

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?

With 0% schema description coverage, the description adds significant value by explaining all three parameters: 'column' as ID or name, 'name' as new column name, and 'board' as ID or name required for name lookup. This clarifies the purpose of each parameter beyond just their types, though it doesn't provide format examples or constraints beyond what's implied.

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 the verb 'rename' and resource 'column', making the purpose immediately understandable. However, it doesn't differentiate from sibling tools like 'update_card' or 'move_column' which could also modify column properties, leaving some ambiguity about when this specific rename operation is needed versus other column-modifying tools.

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 provides no guidance on when to use this tool versus alternatives. With sibling tools like 'move_column' and 'update_card' that might also affect columns, there's no indication of when renaming is the appropriate operation versus other column modifications. The Args/Returns sections are structural documentation, not usage guidance.

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