List company relations

well_list_company_relations
Read-only

List the typed relations between this workspace's companies and other companies: who is a customer, a supplier, a parent or a partner of whom. Use it to answer "who do we sell to", "who do we buy from", "which company owns this one".

An edge runs from the source company to the target company: a customer link points from the customer to the own company it bills, a supplier link from the company the workspace buys from to the own company. Each row carries link_type_code — the stable code of the relation kind ("client", "supplier", "parent", "partner") — next to link_type, its older native twin; read link_type_code. Rows a legacy writer has not re-stamped yet carry link_type_code null: treat those as link_type. valid_to null means the edge is open; a set valid_to means it closed.

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

NameRequiredDescriptionDefault
limitNoMax edges returned (default 25).
workspace_idNoTarget 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_idNoThe 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_scopeNoRestrict 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

NameRequiredDescriptionDefault
errorNo
successYes
relationsYes
conversation_idNoThe conversation this result belongs to. Pass it back as the conversation_id argument on every later Well call in the same conversation.
newly_connectedNoTools 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_workspaceNoThe workspace that answered, when the caller named none and the token authorizes several.
conversation_id_noteNoPresent only when the server opened a fresh lane, stating that no choice recorded earlier was read.
conversation_id_sourceNoWhere the conversation id came from: the host's own request meta, the caller's argument, or a fresh lane the server opened.

TDQS

A4.5/5.0
Behavior5/5

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

Annotations already mark it read-only and non-destructive, and the description adds substantial semantics beyond them: edge direction, link_type_code vs legacy link_type null handling, valid_to open/closed meaning, and workspace scoping behavior. This is rich disclosure for interpreting the returned rows correctly.

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?

Purpose is front-loaded, followed by structured edge semantics and workspace instructions. Despite its length, each paragraph adds needed context for correctly reading or scoping the relation list, with no evident filler.

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 output schema and annotations, the description supplies the remaining domain semantics an agent needs: what an edge means, how to interpret link_type_code and valid_to, and when workspace_id is required. Nothing essential for correct invocation is missing.

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%, so all four parameters are already documented in the schema. The description reinforces workspace_id usage but adds no syntax or format details beyond the schema, making 3 the appropriate baseline.

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 the typed relations between this workspace's companies and other companies") and enumerates the relation kinds and questions it answers. An agent can distinguish it from generic company or counterparty tools by the typed-edge scope.

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 concrete usage contexts ("who do we sell to", "who do we buy from", "which company owns this one") and clarifies workspace_id behavior when the token authorizes multiple workspaces. It does not explicitly contrast with sibling tools such as well_list_counterparties or well_list_customers, so full when-not/alternatives guidance is missing.

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