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

Annotations already declare readOnlyHint=false and destructiveHint=true, so the safety profile is covered. The description adds one useful behavioral detail — the index ordering convention (0 = top) — but says nothing about how moving a checklist shifts the other checklists, what happens with an out-of-range index, or permission requirements.

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 twelve-word sentence with the primary action front-loaded and the ordering caveat tucked into a parenthetical. No filler, nothing repeated from the title.

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 and a mutation annotation set, the description covers what changes but omits the reordering side effects on sibling checklists, error behavior for bad indices, and partial-update semantics. Sufficient to attempt a call, not to predict its full effect.

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 carry parameter meaning. It does explain the index parameter's ordering semantics (0 = top), but title and checklistId are left entirely undocumented, and it never states whether title and index can be supplied together in one call.

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 two specific operations (rename, move) on a precisely scoped resource (a checklist within a task), which cleanly separates it from add_checklist, delete_checklist, and update_checklist_item. An agent can select this tool without opening the 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?

Usage is implied by the stated operations (use this to rename or reorder a checklist), but there is no explicit when-to-use guidance, no mention of alternatives such as update_checklist_item, and no stated prerequisites. Adequate but not directive.

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