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

With no annotations, the description carries the full safety burden, and it does disclose one genuinely useful behavioral trait: queued Nova posts survive the row removal. It omits whether the deletion is permanent/reversible, what happens to already-scheduled or published assets attached to the row, and whether special permissions are needed.

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 tight sentence with the core action front-loaded and the caveat placed in a parenthetical. Nothing is wasted and nothing needs reordering.

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 destructive tool with zero annotations, no output schema, and two of three parameters undocumented, the description is too thin: permanence, effects on attached assets, and error/edge conditions (e.g. deleting a scheduled row) are all unaddressed.

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 only 33% — only notification_message is documented, and that documentation lives in the schema, not the description. The description says nothing about what calendar_id and row_id must reference or how to obtain them, so it fails to compensate for the coverage gap.

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 gives a specific verb ('Remove') and a bounded resource ('one post row from a content calendar'), which also implicitly distinguishes it from the plural sibling delete_calendar_rows. It does not name that sibling or the cancel_* alternatives explicitly, so an agent still has to infer the boundary.

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 parenthetical 'does not cancel Nova-queued posts' hints at when this tool is insufficient and points at the cancel_* family by implication. However, there is no explicit 'use X instead' routing versus delete_calendar_rows, cancel_publishing_history, or unschedule_calendar_row, so the usage guidance remains inferred rather than stated.

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