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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so safety is covered. The description adds genuinely non-obvious behavior: removal is soft (the curated copy keeps its note, links and saves), it only affects the working version, and readers continue seeing the last approved version until the owner approves an update. It does not restate auth requirements beyond the implied curator confirmation.

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 tight sentences, front-loaded with the action, then recovery, then the publication-model caveat. The middle sentence's phrasing ('Curated keeps it with its note, links and saves') is slightly compressed and takes a beat to parse, but nothing is wasted.

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 one-parameter mutation with no output schema and annotations that already declare the safety profile, the description supplies everything an agent needs: reversibility, scope of effect, and the staged-versus-published visibility model. No material gap remains.

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?

There is a single parameter with 100% schema description coverage ('Item id from list_items or search_items'), so the schema already carries the semantics. The description adds nothing about itemId format or sourcing beyond what the schema states, which is the expected baseline when the schema does the heavy lifting.

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 and resource ('Remove one pick from a list') and immediately distinguishes the operation from its inverse by naming restore_item. An agent can tell this apart from delete_list, unsave_item, or update_item without opening any schema.

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?

Gives a prerequisite ('Confirm with the curator first') and names restore_item as the recovery path, which is clear context for when to use it. It stops short of explicit when-not-to-use guidance (e.g., versus delete_list for removing a whole list), so it is clear but not fully routing.

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