IndyKite Capture - delete relationships

This skill builds the request body for the Capture API's batch relationship delete endpoint - removing typed connections between nodes in the IndyKite Knowledge Graph (IKG) while leaving the nodes in place:

POST <API_URL>/capture/v1/relationships/delete

Each entry identifies one relationship the same way it was created: source node, target node, and relationship type. The JSON file is the deliverable, ready to be POSTed by any application.

The [MCP server](../indykite-mcp-server/SKILL.md) does not currently expose Capture endpoints; the JSON bodies this skill produces are for direct REST use and remain valid if Capture tools are added later.

When to use

Activate this skill when the user wants to:

• disconnect two entities - revoke an OWNS / CAN_DRIVE / ACCEPTED edge - while keeping both nodes;
• undo a batch created with [indykite-capture-upsert-relationships](../indykite-capture-upsert-relationships/SKILL.md).

Do not activate this skill to:

• delete the nodes themselves - use [indykite-capture-delete-nodes](../indykite-capture-delete-nodes/SKILL.md);
• remove only a relationship's properties (edge survives) - use [indykite-capture-delete-relationship-properties](../indykite-capture-delete-relationship-properties/SKILL.md);
• create relationships - use [indykite-capture-upsert-relationships](../indykite-capture-upsert-relationships/SKILL.md);
• delete through a CIQ policy + Knowledge Query - use [indykite-ciq-delete](../indykite-ciq-delete/SKILL.md).

Prerequisites

• An IndyKite project with an AppAgent whose credentials are configured for the calling application (Credentials guide).
• For each relationship: the source and target (type, external_id) pairs and the relationship type.

Steps

1. List the relationships to delete

2. Assemble the request body

One JSON object: { "relationships": [ … ] }, 1-250 entries per request. On a composite IKG, add top-level "useglobaldb": true to delete relationships stored in the global constituent (Data Residency guide); omit it on a regular IKG. A ready example: [assets/delete-relationships.json](assets/delete-relationships.json).

{
  "relationships": [
    {
      "source": { "external_id": "ryan", "type": "Person" },
      "target": { "external_id": "kitt", "type": "Car" },
      "type": "CAN_DRIVE"
    }
  ]
}

This file is the deliverable - any HTTP-capable application can send it.

3. Send it (optional)

The endpoint authenticates the calling application (its AppAgent credentials). Which credential goes in which request header is covered by the Credentials guide.

A runnable shell helper builds the authenticated request: [scripts/capture.sh](scripts/capture.sh) — run with --print to preview the curl (host-pinned; token redacted). Deletion is destructive: preview with --print, and confirm the edge list, before sending.

4. Read the results

A 200 returns one result per relationship, in order: { "results": [ { "id": "gid:…" } ] }. Field shapes and error semantics: [references/capture-reference.md](references/capture-reference.md).

Outcome

• A valid { "relationships": [ … ] } delete body exists, each entry naming source, target, and type.
• If sent, those relationships are gone from the IKG - policy conditions and queries that traversed them no longer match - while both endpoint nodes remain.

• [references/capture-reference.md](references/capture-reference.md) - field reference, useglobaldb behavior, batch limits, and error semantics.
• [assets/delete-relationships.json](assets/delete-relationships.json) - ready request body removing a CAN_DRIVE edge.
• [scripts/capture.sh](scripts/capture.sh) - Bash helper that POSTs a body file to /capture/v1/relationships/delete (host-pinned; --print to preview).

Agent-specific notes

This skill uses generic markdown instructions and works across all agents listed in the [README](../README.md). The agent needs to be able to write a JSON file; sending it additionally requires HTTP access (curl or any HTTP client).
