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

No annotations are provided, so the description carries the full burden. It usefully discloses the side effect of syncing pending items from Nova and the publisher_pid path requirement, but it does not state whether the operation is read-only overall, what happens to existing history, or any auth/rate-limit details.

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?

Two sentences, front-loaded with the core action and immediately followed by the important sync side effect and prerequisite. There is no wasted text, though 'same as schedule_calendar_row' is slightly cryptic without that tool's context.

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 simple list tool with one optional parameter and no output schema, the description covers the action, side effect, and path prerequisite. However, it lacks detail about return shape/pagination and does not clarify its relationship to get_publishing_history_item, leaving some contextual gaps.

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 100%, so the schema already documents the single optional notification_message parameter. The description adds useful context about a publisher_pid path parameter not present in the input schema, but it does not explain notification_message semantics beyond what the schema provides.

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 states a specific verb and resource ('List publishing history') and scopes it to the project. It also discloses a notable behavior ('syncs pending items from Nova') that distinguishes it from a pure read. It does not explicitly distinguish itself from the sibling get_publishing_history_item, but the purpose is clear.

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?

Usage is implied by the tool name and the mention of syncing pending items, but there is no explicit guidance on when to use this versus get_publishing_history_item or cancel_publishing_history. It does provide the prerequisite that publisher_pid is required in the URL path, which is useful context.

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