update_party

Update top-level fields on an existing party record and append new email, phone, address, or website entries.

Instructions

Update top-level fields on an existing party (about, firstName/lastName/name/title/jobTitle, ownerId). Only the fields you provide are changed. Child arrays (emailAddresses / phoneNumbers / addresses / websites) on this tool are APPEND-ONLY: items are merged into the existing list, not replaced. For surgical changes — replacing one email, removing one phone number, fixing the type on one address — use the dedicated atomic tools: add_party_email_address / remove_party_email_address_by_id (and the phone/address/website equivalents).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
idYes
firstNameNo
lastNameNo
titleNo
jobTitleNo
nameNo
fieldsNoSet custom field values on this record. PARTIAL UPDATE: only the definitions you list are touched; any field NOT in this array is left unchanged. Discover available definitions via list_custom_fields; read current values via get_party with embed='fields'.
aboutNo
emailAddressesNoAPPEND-ONLY: items are merged into the existing list, never replaced. For atomic add/remove/replace use add_party_email_address and remove_party_email_address_by_id. Passing `[]` here is a silent no-op (does not clear the list and does not advance updatedAt).
phoneNumbersNoAPPEND-ONLY: items are merged into the existing list, never replaced. For atomic add/remove/replace use add_party_phone_number and remove_party_phone_number_by_id.
addressesNoAPPEND-ONLY: items are merged into the existing list, never replaced. For atomic add/remove/replace use add_party_address and remove_party_address_by_id. The `country` field is mapped through Capsule's country dictionary — see `add_party_address.country` for the dictionary edges (small canonical-English-name list; inputs not in the dictionary are REJECTED with 422, not silently dropped).
websitesNoAPPEND-ONLY: items are merged into the existing list, never replaced. For atomic add/remove/replace use add_party_website and remove_party_website_by_id.
ownerIdNoAssign to user ID. On create_party, defaults to the API-token owner when omitted. Once set, this connector cannot clear the owner back to null — use Capsule's web UI for that. Discover IDs via list_users.
Behavior5/5

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

Despite no annotations, the description extensively discloses behavioral traits: append-only semantics for child arrays, partial update for top-level fields, custom field quirks (null handling, boolean two-state, number read-back as string, audit-log noise), ownerId limitation, and country validation. This fully compensates for missing annotations.

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 description is somewhat lengthy but well-structured, front-loaded with the core purpose. Every sentence adds necessary detail for correct usage. Minor redundancy could be trimmed, but it remains efficient for the complexity.

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?

Given the tool's complexity (13 parameters, no output schema, many siblings), the description is remarkably complete. It covers partial update, append-only, custom field quirks, country quirks, ownerId limitation, and alternatives. It even addresses audit-log noise, meeting a wide range of agent needs.

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

Parameters5/5

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

Schema coverage is only 46%, but the description adds immense value beyond the schema. For each child array it explains append-only behavior and references atomic tools. The 'fields' parameter includes a comprehensive guide with edge cases. Other parameters like ownerId and addresses get detailed context (defaults, limitations, country dictionary).

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 explicitly states it updates top-level fields on an existing party, lists specific fields, clarifies partial update semantics, and distinguishes append-only behavior for child arrays. It also directs to atomic tools for surgical changes, differentiating it from siblings like add_party_email_address.

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 clear guidance on when to use this tool (for top-level fields and append-only array modifications) and when not to (for surgical changes on child arrays, naming specific alternatives like add_party_email_address and remove_party_email_address_by_id).

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