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

Annotations already declare destructiveHint=true, so the base bar is met by structured data; the description nonetheless adds two facts not present there: deletion has dependent-record effects that should be reviewed first, and an approval gate may apply at both the MCP-configuration level and the business workflow level. It stops short of saying the deletion is permanent or what happens to data held in the column.

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?

Three short sentences, front-loaded with the operation, then the risk warning, then the approval caveat. Little waste, though the opening sentence duplicates the title and the approval sentence is generic boilerplate that recurs across the tool set.

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?

With an output schema present and destructive annotations covering the safety profile, the description only needs to add the human-judgment context, which it partly does (cascade risk, approval gates). It remains incomplete on permanence and on what dependent records are actually affected, which is the key question before invoking a destructive delete.

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%, so the description must compensate but says nothing at all about the single `id` parameter. The parameter is a required UUID and its meaning as the milestone-column identifier is fairly self-evident from the tool name, so this is a gap rather than a blocker.

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?

"Delete milestone_column" restates the tool name and title verbatim without adding scope, so it reads as a tautology. The one distinguishing fact an agent needs — that this removes a column definition (and presumably its stored values) from the milestone matrix rather than a milestone itself — is not stated, leaving it ambiguous against delete_milestone and update_milestone_column.

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 only guidance is the caution "Review dependent-record effects before confirming," which is a warning rather than a when-to-use rule. Nothing says when to prefer this over update_milestone_column, reorder_milestone_columns, or when deletion is simply not appropriate, and no prerequisites or alternatives are named.

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