list_side_conversations

Read-onlyIdempotent

Fetch side conversations attached to a ticket to surface parallel email or Slack threads from the Collaboration add-on.

Instructions

List side conversations (Collaboration add-on) attached to a ticket as paginated skeletons. Plan-gated, on instances without the Collaboration add-on the call degrades to a structured upstream_error envelope with the underlying http_status, not a thrown failure. Also scope-gated (config_plus_audits or full). Use to surface the parallel email/Slack thread on a ticket; for the main public conversation use get_ticket_comments.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
limitNoMax items to return. Default 100. The full corpus is fetched and cached server-side; this only limits what the response carries.
cursorNoOpaque pagination token from a previous response. Slices the next page from the cached corpus. Stale cursors (older than the cache TTL) auto-reset to offset 0 and set cursor_invalidated: true.
fieldsNoWhitelist of field names. Overrides the default projection. Use to opt into extra fields (e.g. ["id","title","active","position","category_id","updated_at"]) without going fully verbose.
filterNoStructured filter applied to the cached corpus before slicing. Supported keys: active (bool), category_id (number/string), title_contains (string, case-insensitive), updated_since (ISO timestamp). Unsupported keys are ignored with a note in the response.
refreshNoBypass cache and re-fetch from Zendesk
verboseNoReturn full side-conversation objects instead of the thin projection
instanceNoOverride the sticky instance for this call
ticket_idYesTicket ID
Behavior5/5

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

Annotations provide readOnlyHint, openWorldHint, idempotentHint. Description adds plan-gated degradation to upstream_error envelope, scope-gating, caching behavior with cursor staleness, and pagination details, all beyond annotations.

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?

Two sentences plus succinct details. Front-loaded with main purpose, then constraints and usage. No wasted words.

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?

Covers plan-gating, scope-gating, and usage alternative. However, without output schema, the description could describe the return format (what skeleton fields are included) for completeness.

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% with detailed parameter descriptions. The description does not add extra parameter meaning beyond the schema, so baseline 3 applies.

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?

Clearly states it lists side conversations attached to a ticket as paginated skeletons, distinguishing from get_ticket_comments for the main public conversation. Specific verb and resource.

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?

Explicitly tells when to use (surface parallel email/Slack thread) and when not (use get_ticket_comments for main conversation). Also mentions plan-gating and scope-gating.

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