threads_update

✏️ Update a conversation thread: rename it, add notes/description, move it to a folder, or take it out of sync.

When to use:

  • User wants to rename a chat or group

  • User wants to add notes/context about a conversation

  • User wants to organize threads into folders

  • User wants a chat to stop showing up and stop syncing (synced=false) — e.g. the personal chats on an account that is only in the workspace for its work groups. Nothing is deleted; synced=true brings it back.

For DM threads, renaming also updates the linked contact's display name by default. Pass thread_id for one thread, or thread_ids to apply the same change to several. Ids come from threads.list / search.threads.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
titleNoNew title for the thread (max 255 chars). For a DM this ALSO renames the linked contact, so an empty string is ignored, not applied — omit the parameter when you are not renaming.
syncedNofalse takes the chat out of sync: it disappears from the inbox, from knowledge/RAG search, and the sync service stops fetching it. Messages already stored are kept and nothing is deleted. true puts it back. The decision survives later syncs. OMIT to leave sync as it is.
folder_idNoMove thread to this folder (null removes from folder)
thread_idNoThread ID from threads.list. Use this OR thread_ids.
thread_idsNoSeveral thread IDs to apply the same change to, e.g. taking a batch of personal chats out of sync in one call. Use this OR thread_id.
descriptionNoAI context / notes for this thread. Empty string clears description.
in_workspaceNoRun this one call in this workspace id instead of the session's. Nothing is stored; other sessions are not affected.
update_contactNoFor DM threads, also rename the linked contact (default: true)

TDQS

A4.5/5.0
Behavior4/5

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

Annotations declare readOnlyHint=false and destructiveHint=false; the description confirms and enriches this with 'Nothing is deleted; synced=true brings it back' and that the sync decision persists across later syncs. It also discloses the DM rename side-effect and the ignored-empty-string rule. Idempotency behavior (idempotentHint=false) is left unaddressed, so it falls just short of a 5.

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?

Front-loaded one-line summary followed by clean, scannable bullets; each sentence largely earns its place. There is mild redundancy with the schema (DM rename and synced behavior are restated), which keeps it from a 5.

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 mutation tool with 8 optional parameters and no output schema, the description covers the key operations, side effects, and persistence rules. It omits any mention of return values or error behavior and does not address the in_workspace override, leaving minor gaps.

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; the description still adds value by telling the agent where ids come from (threads.list / search.threads) and reinforcing the thread_id/thread_ids mutual-exclusion semantics. It does not add much beyond the richly documented schema for the remaining parameters.

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 a specific verb+resource ('Update a conversation thread') and enumerates the exact operations (rename, add notes/description, move to folder, take out of sync). An agent can immediately tell this is the mutation counterpart to threads_list/search_threads and distinct from threads_delete.

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?

Provides an explicit 'When to use' list with concrete scenarios, including the non-obvious case of taking personal chats out of sync on a work-only account. It also explains the thread_id vs thread_ids choice and clarifies that nothing is deleted, effectively steering away from delete semantics.

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