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

Annotations already declare destructiveHint=true, readOnlyHint=false, and openWorldHint=false, so the agent knows this is an irreversible write. The description adds nothing beyond that: it never says what "resolve" does to the notification (delete it, mark it closed, change status), whether it can be undone, or whether permissions are needed. For a destructive tool, that 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?

It is a single short sentence with no filler and the action is front-loaded, which is structurally sound. But the brevity reflects under-specification rather than tight editing, so it does not earn above a middling score.

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?

An output schema exists, so return values need not be described. Still, for a destructive mutation with a 0%-covered schema and a sibling that may overlap (notifications_ack), the definition leaves the agent guessing about effect, prerequisites, and parameter formats — insufficient for the tool's complexity.

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 for two undocumented parameters. It does not: the format/source of notification_id is unexplained, and connection_context (an opaque mctx_v1_ token) is never mentioned. With a low-coverage schema and no compensating text, this is a clear failure.

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 names a verb ("Resolve") and a resource ("TaskTools notification"), so the basic action is identifiable. However, "resolve" is ambiguous — it could mean acknowledge, dismiss, or delete — and nothing distinguishes it from the close sibling notifications_ack, which appears to do something similar. Purpose is stated but not disambiguated.

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 no guidance on when to use this tool versus notifications_ack, notifications_scan, or notifications_list. No preconditions, no mention of which notification states are resolvable. The agent must infer the routing decision entirely.

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