Delete ledger account

well_delete_ledger_account

Destructive

Soft-delete one unused native ledger account. Use ledger_account_id from well_query_records on ledger_accounts. Connector-owned accounts and accounts referenced by journal lines cannot be deleted. Ask for confirmation before deleting the definition.

Input Schema

Name	Required	Description
`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.
`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.
`ledger_account_id`	Yes

Output Schema

Name	Required	Description
`code`	No
`error`	No
`success`	Yes
`reply_lines`	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.
`near_candidates`	No
`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.
`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.
`near_candidates_truncated`	No

TDQS

A4.4/5.0

Behavior4/5

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

Annotations already carry destructiveHint=true and readOnlyHint=false, so the safety profile is known; the description adds real value by revealing that the delete is a soft-delete, that connector-owned and journal-referenced accounts are blocked, and that confirmation is expected. It does not spell out what a soft-delete leaves behind or how to restore it, which keeps it from a 5.

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 tight sentences: the action first, then the id source and eligibility constraints, then the confirmation requirement. No repetition of the title and no filler.

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 and destructive annotations already present, the description covers what the agent needs to decide and invoke correctly. It leaves open what soft-deletion means for recovery and what happens to references, a minor gap for a single-parameter destructive tool.

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 80%, and the one undocumented parameter (ledger_account_id has no schema description) is precisely the one the description explains — it must come from well_query_records on ledger_accounts. That compensates for the schema gap beyond the baseline 3.

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?

"Soft-delete one unused native ledger account" gives a specific verb (soft-delete), resource (ledger account), and scope qualifiers (one, unused, native), which cleanly separates it from well_create_ledger_account, well_update_ledger_account and the other well_delete_* tools.

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?

It tells the agent where to source the id (well_query_records on ledger_accounts), states two hard preconditions under which deletion is impossible, and requires confirmation before acting. It stops short of naming an alternative action (e.g. deactivating via well_update_ledger_account) for accounts that cannot be deleted.

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