Well

Remove contact channel

well_remove_contact_channel

Destructive

Remove a contact channel from a company or person.

Wraps the resource-scoped DELETE endpoints (DELETE /v1/{companies,people}/:id/{emails,phones,web-links,locations}/:channelId).

Pass channel_id = the UUID of the specific channel row to remove (NOT the parent). Find it by reading the parent with well_query_records and selecting the channel's id field.

Input Schema

TableJSON Schema

Name	Required	Description
`parent`	Yes	Parent record type: company or person
`channel`	Yes	Channel to remove: email \| phone \| web_link \| location
`parent_id`	Yes	UUID of the parent company or person
`channel_id`	Yes	UUID of the specific channel row to remove
`workspace_id`	No	Target workspace. Omit when the token authorizes one workspace. Required when it authorizes several — a write lands in exactly one workspace and this call would not say 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.
`idempotency_key`	No	Optional client-supplied key. A retried write with the same key returns the original result instead of re-applying the operation.

Output Schema

TableJSON Schema

Name	Required	Description
`error`	No
`parent`	No
`channel`	No
`success`	Yes
`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.
`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.

TDQS

A4.4/5.0

Behavior4/5

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

Beyond the destructiveHint=true annotation, the description discloses that this wraps DELETE endpoints and warns that channel_id must be the specific channel row, NOT the parent — a meaningful scoping caveat that prevents an agent from accidentally deleting the parent record. It doesn't cover consequences to related data, but the annotation already carries the destructive profile.

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 short sentences, zero filler. Purpose is front-loaded, then endpoint context, then the critical usage instruction. Every sentence earns its place.

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?

Complete for a 7-param tool with an output schema and destructiveHint annotation. The main pitfall (confusing channel_id with parent_id) is addressed, and workspace_id/conversation_id/idempotency_key are fully documented in the schema. Minor gaps like permission requirements are not covered, but they are not glaring given the schema richness.

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 100%, so the baseline is 3. The description adds genuine value by clarifying the parent/channel relationship — channel_id is the row to remove, not the parent — and by chaining to well_query_records for how to obtain it, which the schema alone does not convey.

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 ('Remove a contact channel from a company or person') and clarifies the exact target by distinguishing the channel row from the parent. The 'NOT the parent' note disambiguates it from broader deletion tools like well_delete_company and well_delete_person.

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 an explicit lookup procedure: find channel_id by reading the parent with well_query_records and selecting the channel's id field. It names the alternative for discovery (well_query_records) yet doesn't explicitly contrast with the sibling well_add_contact_channel, though the verb 'remove' vs 'add' makes the pairing self-evident.

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