List smart fields

list_smart_fields

Read-onlyIdempotent

List the workspace's smart-field definitions — the merge fields available to signature templates (e.g. first name, job position, custom fields). Each carries its kind, whether it's a default field, and an integration_id when its values are synced. The computed Email field is not exposed. Paginated (page/limit).

Input Schema

TableJSON Schema

Name	Required	Description
`page`	No	1-based page (default 1).
`limit`	No	Page size, 1–100 (default 50).
`context`	Yes	Explain in 15-25 words, in third person, why this tool is called and how it supports the user's goal. For analytics only. You MUST describe only the abstract purpose of the tool call. NEVER include, repeat, paraphrase, or infer personal, sensitive, or identifying information from the user request or tool results, including names, emails, phone numbers, IPs, IDs, or credentials. You MUST generalize specific entities into roles such as "a user", "the customer", or "an account". Example: "Retrieving a customer's recent orders to investigate a billing issue and help support determine the appropriate resolution."
`max_pages`	No	Page cap when auto_paginate is true (default 5).
`auto_paginate`	No	Fetch multiple pages up to `max_pages` (default false).

Output Schema

TableJSON Schema

Name	Required	Description
`data`	Yes
`truncated`	Yes	True when auto_paginate stopped at max_pages with more results remaining.
`pagination`	Yes
`pages_fetched`	Yes

A4.1/5.0

Behavior4/5

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

Annotations already declare the safe read-only, idempotent, non-destructive profile, so the bar is lower. The description adds real value beyond them: the computed Email field is deliberately not exposed, results are paginated, and returned fields carry kind/default/integration_id semantics.

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?

Three sentences, no waste, front-loaded with the verb and resource before the caveats (Email field excluded) and the pagination note. Every sentence earns its place.

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?

An output schema exists, so return values need not be spelled out, and a full 100% schema coverage plus read-only annotations mean the description only needs to add scope and exclusions. It does both, leaving nothing an agent needs to call this correctly.

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%, including page/limit/auto_paginate/max_pages/context, so the schema carries parameter meaning. The description only restates pagination ('page/limit') and adds no format or default details beyond the schema; 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?

States a specific verb (List) and resource (smart-field definitions) and immediately clarifies what those are: the merge fields available to signature templates. The scope ('the workspace's') plus the examples (first name, job position, custom fields) distinguish it from sibling list_* tools and from create/update/delete_smart_field.

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

Usage Guidelines3/5

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

Usage is implied rather than stated: an agent can infer you call this to discover available merge fields for signature templates, and the exclusion of the computed Email field is a useful boundary. But there is no explicit when-to-use/when-not or pointer to an alternative sibling, so it stays at minimum-viable.

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