List child boards

list_board_children

Read-only

List the direct child boards of a given board. Use this to navigate the board hierarchy one level at a time — more efficient than list_boards with depth when you only need one node's immediate children. asset_count covers the board AND every board nested under it (each group/stack counted once); list_assets on a board returns only assets sitting directly on it unless you pass nested_assets: true, so compare the count against that, not the plain listing.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Input Schema

Name	Required	Description	Default
`token`	Yes	Parent board token — the parameter name is `token`, not `board_token` or `collection_token`.
`organization`	No	Workspace slug, as returned by list_organizations. Omit it when the account has a single workspace — it is then resolved from your token. Pass it only when the account has several, or when you mean a workspace other than the obvious one.

A4.7/5.0

Behavior5/5

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

The annotations already establish a non-destructive, read-only operation. The description adds substantial behavior not captured there: `asset_count` is recursive across the board and all nested boards, groups and stacks are counted once, and `list_assets` is direct-only unless `nested_assets: true` is passed.

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?

The purpose and selection guidance are front-loaded, followed by a relevant counting caveat. Although the final sentence is dense, all three sentences provide actionable information 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?

For a two-parameter read tool, the definition supplies the hierarchy scope, an alternative, and the key output-count interpretation needed to avoid misuse. The fully documented schema covers invocation inputs, and the lack of an output schema is substantially mitigated by the explanation of `asset_count`.

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

Parameters3/5

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

Schema coverage is 100%, and both `token` and `organization` already have detailed semantics, so the baseline is 3. The description's reference to a given board adds no meaningful input guidance beyond that schema; its extra detail concerns output and count behavior instead.

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?

The opening sentence gives a specific verb, resource, and scope: listing only the direct children of a specified board. The comparison with `list_boards` with depth further distinguishes it from a close sibling.

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

Usage Guidelines5/5

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

It explicitly says to use this tool for navigating the hierarchy one level at a time or when only one node's immediate children are needed. It also identifies `list_boards` with depth as the less efficient alternative for that case.

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