Change the items on Plan boards

change_items
Destructive

Add, change, move or delete cards, in order: add {title, type, status, fields}, set {item, fields, clear, type}, move {item, status, before}, delete {item}. Name things as the board shows them: a column by its name ("In Progress"), a card type by name ("Bug"), a custom field by name, an assignee by a person’s name, an item by its number ("#12"). An unknown column, type or field is refused with the ones there are. Everyone with the document open sees each change at once.

Input Schema

  5. Added

TDQS

A4.5/5.0
Behavior4/5

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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the write/destructive profile is covered. The description adds genuine context beyond that: unknown columns/types/fields are refused, and 'Everyone with the document open sees each change at once' discloses the real-time broadcast behavior. Sequential ordering/abort semantics are present but partly duplicated from the schema.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the four operations, then naming conventions, then refusal behavior, then the real-time note. Dense but every sentence carries actionable content with no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, return values need not be explained, and annotations cover the destructive profile. The description still supplies operation ordering, naming resolution, error handling, and visibility semantics, so an agent has everything needed to invoke it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3 and the schema already documents every field in depth. The description adds a compact per-op signature (add {title, type, status, fields}, set {item, fields, clear, type}, etc.) plus a unified naming-resolution rule ('name things as the board shows them') that spans parameters the schema documents only individually.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States specific verbs (add, change, move, delete) against a concrete resource (cards/items on Plan boards) and enumerates the four operations with their argument shapes. This clearly distinguishes it from siblings like change_board (board settings) and change_card_types (type schema), which it explicitly routes to.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives clear operating context: name things as the board shows them, and if a field is missing 'add it with change_card_types', while card types come from list_items. It does not explicitly state when to prefer this over change_board, so it stops short of full when/when-not routing.

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