List the groups of a LinkedIn profile

linkedin_get_profile_interests_groups

Read-onlyIdempotent

List the groups from the interests section of a LinkedIn member's profile, each with its name, link, logo and member count. Page on with the nextStart from the previous response. Read-only: returns public data and changes nothing. Costs 1 credit per request.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Input Schema

Name	Required	Description
`count`	Yes	Number of results to return (1–100). Defaults to 100.
`start`	No	Number of results to skip. Defaults to 0.
`publicId`	Yes	The member public identity, or the profile link itself, e.g. "williamhgates" or "https://www.linkedin.com/in/williamhgates".
`cacheOnly`	No	Return only a cached result and never scrape live. With `cacheMaxAgeHours`, only a result that recent is returned; without it, the latest cached result of any age. Responds 404, at no cost, when there is none, e.g. true.
`cacheMaxAgeHours`	No	Accept a cached result scraped up to this many hours ago. A cached result costs no credits, and its `cachedAt` says when it was scraped. When no cached result is that recent, the data is scraped live at the normal price. Leave it out to always scrape live, e.g. 24.

A3.7/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so 'read-only … changes nothing' largely restates structured data. However, 'Costs 1 credit per request' is genuinely new cost/rate context not present in any structured field, and the pagination note adds continuation behavior. That is meaningful added value beyond the 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?

Three short sentences, front-loaded with purpose, then pagination and cost. Nearly every sentence earns its place; the 'returns public data and changes nothing' clause is somewhat redundant against the annotations, 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?

There is no output schema, but the description compensates by naming the returned fields (name, link, logo, member count). Pagination and per-request credit cost are covered, and cache behavior is fully described in the schema, so the definition is nearly self-sufficient for a 5-parameter read tool.

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%, with count, start, publicId, cacheOnly and cacheMaxAgeHours all documented in-schema, so the baseline is 3. The description adds only pagination guidance via `nextStart`, which isn't itself a parameter name in the schema and could mildly confuse an agent mapping it onto `start`.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('List the groups') and narrows the scope to 'the interests section of a LinkedIn member's profile', which separates it from search-style siblings. It also enumerates the returned fields, so an agent knows exactly what data comes back. It stops short of naming a sibling to avoid, so a 4 rather than a 5.

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?

The 'interests section' scoping implies when to use it, and the pagination sentence tells the agent how to continue an existing result set. There is no explicit guidance on when to prefer this over linkedin_search_groups or the sibling interests endpoints (companies, schools, newsletters), so the agent must infer the boundary.

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