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

Annotations already declare readOnlyHint=false, openWorldHint=false and destructiveHint=true, lowering the bar. The description adds real context beyond that: privacy scope ("Only the user sees it") and a quota (free plan allows 3 per board). However, it never explains the destructiveHint at all -- no mention of what happens when the 3-view limit is hit, whether an existing view is replaced, or what permissions are needed. Given the annotation explicitly flags destruction, that omission is a meaningful gap.

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 compact sentences with the core action front-loaded and zero filler. Each sentence adds something (what is saved, who sees it, plan limit). Slightly fragmentary parenthetical style keeps it from being a model of structure.

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 no output schema, the description need not explain return values, and annotations cover the safety profile. Yet for a 6-parameter creation tool at 0% schema coverage it leaves the required parameters unexplained and says nothing about failure modes (limit exceeded) or whether the created view is returned/addressable. Adequate conceptual framing, incomplete operational detail.

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% across 6 parameters, so the description must carry the load. It partially does: it names the four view enum values and maps the three filter categories (due date, labels, assignees) to the due/labelIds/assigneeIds properties. But neither required parameter (boardId, name) is explained, the due enum values are not enumerated, and the ID-array format for labelIds/assigneeIds is left implicit.

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?

Specific verb + resource: "Saves a personal view of a board," and it goes further by enumerating what the view contains (board/table/calendar/timeline plus due date, labels, assignees filters). An agent immediately knows this writes a per-user view configuration. It stops short of naming the obvious counterpart (delete_saved_view) or otherwise differentiating itself from the many other create_* siblings, so a 5 is not warranted.

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 implies when this is relevant (you want a personal board view) but never states when to use it versus alternatives or any exclusions. The two facts it does give -- "Only the user sees it" and the 3-per-board free-plan cap -- are constraints rather than selection guidance. Minimum-viable context, no routing help.

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