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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is known. The description adds genuinely new behavioral context: row records are never deleted by this operation, and user-created columns require confirmation. It still does not say whether the column's stored values are lost or whether the action is reversible.

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 core sentence is tight and front-loaded, but the leading token 'FREE (key, Set up, Full on the list)' is cryptic and reads like a plan/tier marker that an agent cannot act on, which costs clarity in the most prominent position.

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 3-parameter destructive mutation with annotations and no output schema, the description covers the essential safety point and the records-are-preserved guarantee. It is still silent on what happens to the column's cell values and what the call returns, which matters for a destructive tool.

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 100%, so the schema already documents all three parameters, and the description's '(by name or title)' reinforces that the column parameter accepts either form rather than an id. Given full schema coverage, this matches the baseline expectation without adding confusion.

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?

States a specific verb and resource — 'remove a column from a list' — and adds the lookup mode '(by name or title)'. It implicitly contrasts with the sibling add_column through the verb, but never names that sibling or any other alternative.

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?

There is one real usage rule: 'ask your user before you remove a column a person made', which tells the agent to confirm before deleting user-created structure. Beyond that there is no guidance on when to remove a column versus reconfiguring with fix_list or update_records, and no stated preconditions.

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