Well

List product add-ons

well_list_product_addons

Read-only

List a product's add-ons, ordered by position. The default page has 50 rows; pages contain at most 100. Pass the returned next_cursor to continue. The response uses public ids only.

When the token authorizes one workspace, call this directly — no workspace call is needed first. When it authorizes several, this read will not guess which one you mean: pass workspace_id on the call.

Input Schema

Name	Required	Description
`limit`	No
`cursor`	No
`product_id`	Yes
`workspace_id`	No	Target workspace. Omit when the token authorizes one workspace. Required when it authorizes several: this read reports one workspace's own figures and will not choose which.
`conversation_id`	No	The conversation id returned by the previous Well result, in its meta under well/conversation_id, in its structuredContent, or in its JSON text block. Pass it back on every call in the same conversation, including a call a card makes, so the chosen workspace and the earlier answers still apply. It decides the conversation on its own: nothing the host states about the session replaces it. Omit it only on the first call of a conversation.
`workspace_scope`	No	Restrict this call to the family: the token's primary workspace plus the company workspaces under it that you are a member of. Unrelated authorized workspaces drop out of the read; row reads merge across the family, while a per-workspace figure still reports exactly one workspace.

Output Schema

Name	Required	Description
`error`	No
`links`	No
`success`	Yes
`next_cursor`	No
`conversation_id`	No	The conversation this result belongs to. Pass it back as the conversation_id argument on every later Well call in the same conversation.
`newly_connected`	No	Tools that connected to this workspace since the last result and that no session was told about yet, oldest first. Present only when at least one tool is new. The connected-line rule says when to tell an entry; when it does, one line per entry, in the person's language: "<name> is connected.". Never fold several entries into one sentence. Each entry comes back once, on one result only: never repeat its line later.
`resolved_workspace`	No	The workspace that answered, when the caller named none and the token authorizes several.
`conversation_id_note`	No	Present only when the server opened a fresh lane, stating that no choice recorded earlier was read.
`conversation_id_source`	No	Where the conversation id came from: the host's own request meta, the caller's argument, or a fresh lane the server opened.

A4.3/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true, so the safety profile is covered; the description adds substance beyond that: default page size of 50, a hard cap of 100, cursor-based continuation via next_cursor, position ordering, and public-id-only responses. The ambiguity behavior for multi-workspace tokens is genuinely useful operational context.

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 with purpose and pagination, then the workspace precondition. Two tight paragraphs with no filler. The workspace paragraph is slightly verbose but every sentence carries decision-relevant information.

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?

With an output schema present, return values need not be explained, yet the description still flags cursor continuation and public-id responses. Combined with the workspace disambiguation rules, an agent has everything needed to call correctly; the remaining gap is minor (no mention of sibling list tools for components/media).

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 50%, so the description must compensate, and it does for three of the undocumented parameters: limit semantics (default 50, max 100), cursor semantics (pass the returned next_cursor), and workspace_id usage rules. Only product_id is left without explanatory text, which the schema pattern and required flag make self-evident.

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 and resource ('List a product's add-ons'), plus ordering ('by position') and scoping ('a product's'), which immediately separates it from well_list_products, well_list_product_components, and well_list_product_media. An agent can identify the right tool without opening any schema.

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

Usage Guidelines4/5

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

Gives explicit prerequisite guidance: call directly when the token authorizes one workspace, no prior workspace call needed; pass workspace_id when it authorizes several because the read 'will not guess.' It does not name alternatives such as well_list_product_components, but the workspace-selection conditions are concrete and actionable.

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