list-contact-folder-child-folders

list-contact-folder-child-folders
Read-only

List child contact folders beneath a specified parent folder to navigate nested folder structures. Returns each subfolder's id, display name, and parent ID.

Instructions

Get a collection of child folders under the specified contact folder.

đź’ˇ TIP: Lists immediate sub-folders under a given contact folder. Returns id, displayName, parentFolderId. Use list-contact-folders to discover top-level folders, then this tool to traverse one level deeper. Supports $filter, $top, $orderby. Note: contact folders are typically a flat list in Outlook clients, but Graph allows nesting via this endpoint.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
topNoPage size (Graph $top). Start small (e.g. 5–15) so responses fit the model context; raise only if needed. Use $select to return fewer fields per item. For more rows, use @odata.nextLink from the response instead of a very large $top.
skipNoItems to skip for pagination. Not supported with $search.
countNoSet true to enable advanced query mode (ConsistencyLevel: eventual). Required for complex $filter on flag/flagStatus or contains().
expandNoNavigation properties to inline, e.g. attachments on a message or event. Only navigation properties can be expanded: expanding a non-navigation property such as a message body fails with "Parsing OData Select and Expand failed", and an unsupported value may be ignored rather than reported. Request ordinary fields with $select instead.
filterNoOData filter expression. Add $count=true for advanced filters (flag/flagStatus, contains()). Cannot combine with $search.
searchNoKQL search query in one pair of double quotes; directory (users/groups) instead quotes each clause with no outer pair. Cannot combine with $filter.
selectNoComma-separated fields to return, e.g. id,subject,from,receivedDateTime
orderbyNoSort expression, e.g. receivedDateTime desc
skiptokenNoNext page: the @odata.nextLink from the previous response. Keep the other arguments the same.
fetchAllPagesNoFollow @odata.nextLink and merge up to 100 pages into one response. Can return enormous payloads—only when the user explicitly needs a full export. Prefer a small $top first, then paginate or narrow with $filter/$search.
includeHeadersNoInclude response headers (including ETag) in the response metadata
contactFolderIdYesValue for the 'contactFolderId' path segment. Pass it under the name 'contactFolderId', not as 'id'. Use the 'id' field of the contact folder object as returned by Microsoft Graph.
excludeResponseNoExclude the full response body and only return success or failure indication

TDQS

A4.3/5.0
Behavior4/5

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

The annotations already establish readOnlyHint and non-destructive behavior. The description adds useful behavioral context beyond that: it returns only immediate children, lists the expected fields (id, displayName, parentFolderId), and notes that Graph supports nesting even though Outlook clients usually show a flat list. It does not address pagination behavior, but the parameter docs cover nextLink and fetchAllPages.

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

Conciseness4/5

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

The purpose is front-loaded and the TIP/note provide useful orientation. The opening sentence and the TIP restate essentially the same operation, so there is minor redundancy that prevents a top score.

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

Completeness4/5

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

For a read-only list tool, the description covers return fields, traversal depth, and the nesting caveat, while the schema fully documents all 13 parameters. Since there is no output schema and the tool has many parameters, a short example of chaining list-contact-folders to this tool would make it even more complete.

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 description coverage is 100%, so the baseline applies; every parameter already has detailed semantics in the schema. The description adds only a high-level mention of $filter/$top/$orderby and the list-contact-folders workflow, which does not materially extend the parameter documentation.

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 description opens with a specific verb+resource statement ('Get a collection of child folders under the specified contact folder') and reinforces it with 'Lists immediate sub-folders under a given contact folder.' It explicitly contrasts this with list-contact-folders for top-level discovery, so the tool is distinguishable from its nearest sibling without inspecting schemas.

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 gives an explicit workflow: use list-contact-folders to find top-level folders, then this tool to traverse one level deeper. It also cautions that contact folders are typically flat in Outlook, which implicitly tells an agent when child-folder traversal may not be needed.

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