Show retargetable connectors

well_show_retargetable_connectors

Read-only

Draw the connector-retarget card so the USER brings a bank (or other ledger) connector across from the membership workspace to this company workspace.

A connector connected on the parent (membership) workspace syncs its transactions there, where they cannot post. This card lists each such connector that could follow this workspace, with how strongly it was proved to belong here and how much history is behind it, pre-ticks the strong matches, and on Confirm retargets the ones the user keeps: a new connector row is created here that borrows the parent's credentials and pulls the history in on its own first sync.

Draw it on the close-books bank step to SHOW the user the connectors they can bring across, let them pick which, and CONFIRM the bring-across, once at least one candidate carries a proof tier other than "no_match" and a transaction count above zero. Drawing the card IS that step, and it waits for the user's Confirm. ONLY when a step needs the candidate count WITHOUT the user seeing a card (a silent gate check that decides whether to offer the card at all) call well_list_retargetable_connectors instead.

Input Schema

TableJSON Schema

Name	Required	Description
`title`	No	Heading for the connector-retarget card, OVERRIDING the default wording. Use it to frame the step in its flow (e.g. "Bring your bank across for the close"). At most 120 characters. Omit for the default wording.
`subtitle`	No	Supporting line under the card's heading. At most 240 characters. Omit for the default.
`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.

Output Schema

TableJSON Schema

Name	Required	Description
`error`	No
`success`	Yes
`next_step`	No	What to do with the card this result renders. Added by the dispatcher when the card asks for a click.
`candidates`	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.
`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.

A4.6/5.0

Behavior5/5

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

Beyond the readOnlyHint annotation, the description discloses the full interaction flow: the card lists candidates, pre-ticks strong matches, waits for the user's Confirm, and on Confirm creates a new connector row that borrows the parent's credentials. It also explains the data model (parent membership workspace, transactions that cannot post there) and that drawing the card IS the step.

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?

The description is long but information-dense)Skip; it front-loads the core action and then explains mechanics, when-to-use, and the alternative. A few phrases are slightly repetitive (e.g., 'Draw it on the close-books bank step to SHOW the user...' restates earlier points), but every paragraph earns its place.

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?

For a tool with an output schema and rich annotations, the description covers everything needed to call it correctly: purpose, prerequisites, user-facing flow, the alternative sibling, and parameter context. Nothing critical 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 coverage is 100% and each parameter already has detailed descriptions (title overrides wording, workspace_id tells which workspace, conversation_id must be passed back). The tool description itself does not add parameter-level meaning, so the baseline 3 applies.

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?

The description states a specific verb and resource: 'Draw the connector-retarget card' that lets the user bring a connector across workspaces. It also explains exactly what the card does (lists candidates, pre-ticks strong matches, retargets on Confirm), which distinguishes it sharply from the sibling well_list_retargetable_connectors.

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

Usage Guidelines5/5

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

The description is explicit about when to use the tool: on the close-books bank step, once at least one candidate has a proof tier other than 'no_match' and a transaction count above zero. It also gives a clear exclusion, telling the agent to call well_list_retargetable_connectors instead when only a silent candidate count is needed without showing the card.

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