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

Annotations declare destructiveHint=true and readOnlyHint=false, so the agent knows this mutates state, but the description adds nothing about what acknowledging actually does (silences? deletes? marks read?), whether it is reversible, or whether it requires ownership of the notification. With annotations carrying the safety profile, the description still should have clarified the semantics of 'acknowledge' versus 'resolve'.

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 front-loaded sentence with no filler or repetition. It is efficient, though its brevity comes partly from omitting information the agent needs rather than from tight editing.

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, state-mutating tool with a required ID and an unexplained second parameter, the description is too thin. Output schema handles return values, but nothing addresses the ack-vs-resolve distinction, prerequisites, or parameter meaning.

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 and does not. It implies a target notification via 'one notification' but never explains notification_id's format or what the opaque mctx_v1_... connection_context pattern is for.

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?

States a specific verb ('Acknowledge') and resource ('one TaskTools notification') with explicit singular scope. However, it does not distinguish itself from the sibling notifications_resolve, leaving the agent unsure whether ack and resolve are the same action or different.

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 statement of when to use this tool versus notifications_resolve, notifications_list, notifications_scan, or notifications_summary. The agent must infer intent from the name alone.

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