DBOPS Changeset Generation

Generate Liquibase database changesets from natural language descriptions, anchored to a real schema and instance from the Harness DBOPS service.

When to Use

When the user asks to:

Create, add, modify, or drop tables, columns, indexes, constraints, or views as Liquibase changeset operations
Generate a database migration or changeset
Fix a failed migration or update an existing changeset
Apply schema changes as Liquibase YAML

Prerequisites

The Skill tool loads this file (SKILL.md) automatically — do not Read it again.

Before generating Liquibase YAML, Read reference.md using the exact path listed in the Skill tool result. It contains all Liquibase YAML rules, change types, rollback patterns, batch migration guidelines, MongoDB JSON string requirements, and the clarifying questions policy. Apply those rules in Step 4 when generating the changeset.

Full Workflow

Step 0: Check for Pre-Seeded Context (ALWAYS do this first)

At conversation start, the initial message may contain a JSON block with pre-selected identifiers injected by the Harness frontend UI:

{
  "dbops_schema_id": "users-schema",
  "dbops_instance_id": "prod-instance"
}

Read this JSON block (if present) before doing any tool calls.

What's in context	What to do
`dbops_schema_id` + `dbops_instance_id`	Skip Steps 1 AND 2 — but immediately fetch instance metadata via `harness_get(resource_type="database_instance", resource_id="<dbops_instance_id>", dbschema_id="<dbops_schema_id>")` to obtain `connector` (needed in Step 3) and check `hasSnapshot` (needed in Step 3-B).
Only `dbops_schema_id`	Skip Step 1 — use this schema ID. Then go to Step 2-A
Neither	Full Steps 1 and 2

Step 1: Discover Database Schemas (skip if `dbops_schema_id` is in context)

Call harness_list for the available schemas:

harness_list(resource_type="database_schema")

The response is a plain JSON array of objects. Each object has:

identifier — used as the schema ID in subsequent calls
name — human-readable name
migrationType — "Liquibase" or "Flyway" (only Liquibase supported)
instanceCount — number of linked instances
primaryDbInstanceId — the designated instance for LLM authoring (may be empty). If non-empty, Step 2-A uses this directly as the instance_id without further discovery.

Disambiguation:

If the array has one schema, select it automatically.
If the array has multiple schemas, use AskUserQuestion (selection mode): Show: [<name> (<identifier>) — <migrationType>, <instanceCount> instances] for each.
If the array is empty: "No database schemas found in this project. Create one in Harness DBOPS first."
If migrationType is "Flyway": "This skill supports Liquibase schemas only."

Step 2-A: Resolve Instance from Schema (when only `dbops_schema_id` is known)

When you have a schema_id but no instance_id (from context OR after Step 1 selection):

Call harness_get to fetch the full schema:

 harness_get(resource_type="database_schema", dbschema_id="<schema_id>")

Check the primaryDbInstanceId field in the response:

If set: use it as the instance_id. Inform the user: "Using primary instance <primaryDbInstanceId> for schema <name>." Then fetch the instance to obtain the connector field needed in Step 3:

harness_get(resource_type="database_instance", resource_id="<primaryDbInstanceId>",
            dbschema_id="<schema_id>")

Read connector from the response.

If empty or missing: fall through to Step 2-B.

Step 2-B: Auto-select Best Instance (when `primaryDbInstanceId` is empty)

Use the database_default_authoring_instance resource to let the server pick the best instance (oldest with a metadata snapshot; falls back to oldest overall):

harness_get(resource_type="database_default_authoring_instance", dbschema_id="<schema_identifier>")

The response is { identifier: string, name: string, hasSnapshot: boolean, connector: string }.

Handling the response:

If the tool call returns results: Use identifier as the instance_id and connector as the connector identifier for Step 3 (no separate instance detail fetch needed). Inform the user: "Using instance <name> (<identifier>) for schema <schema_name>." If hasSnapshot is true, the instance has metadata available for snapshot lookups — proceed to Step 3-B for any changeset intent (create, modify, or drop). If false, skip Step 3-B entirely.
Not found (404 OR empty result): Reply: "No instances found for schema <schema_name>. Please add an instance in Harness DBOPS first — open Harness → DBOPS → Schemas → <schema_name> → Add Instance." — STOP. Do NOT prompt the user for a connector identifier. Do NOT proceed to Step 3. Do NOT generate a changeset.

Step 3: Resolve Database Engine Type from Connector

Invariant. By this point you MUST have a non-empty connector value from Step 0 (fast-path instance fetch), Step 2-A, or Step 2-B — whichever applied. If you do not — for any reason — STOP and surface the Step 2 "instance not found" message to the user. Never ask the user to provide a connector identifier directly; connectors are always derived from an existing DBOPS instance.

Use the connector field obtained in Step 0, Step 2-A, or Step 2-B (whichever ran). Fetch the connector to determine the engine type:

harness_get(resource_type="connector", resource_id="<connector>",
            org_id="<org_id>", project_id="<project_id>")

The connector is always a JDBC connector. Read connector.spec.url and map the prefix:

`connector.spec.url` prefix	Engine
`jdbc:mysql://` or `jdbc:mariadb://`	MySQL
`jdbc:postgresql://`	PostgreSQL
`jdbc:oracle:thin:`	Oracle
`jdbc:sqlserver://`	MSSQL
`jdbc:mongodb://`	MongoDB
`jdbc:cloudspanner:`	Spanner
`jdbc:db2://`	DB2
`jdbc:sybase:`	Sybase
`jdbc:sqlite:`	SQLite

If the URL prefix is unrecognised, proceed with generic ANSI SQL. Do NOT ask the user.

Step 3-B (Optional): Snapshot metadata check

Run this step for any changeset intent (create, modify, or drop) when hasSnapshot is true.

Purpose:

For CREATE intents: verify the target object does not already exist (conflict check).
For modify/drop intents: align names with the latest snapshot.
For foreign key intents: resolve column mappings from snapshot metadata (Step 3-B-4).

3-B-1: List existing object names

Call with dbschema_id, dbinstance_id, and the relevant object_type ("Table", "Index", "View", etc.):

harness_list(
  resource_type="database_snapshot_object",
  filters={
    dbschema_id: "<schema_id>",
    dbinstance_id: "<instance_id>",
    object_type: "Table"
  }
)

Returns { data: string[] } — names of objects of that type in the current snapshot.

If the list API errors or returns an empty data array, treat the snapshot as stale — proceed to Step 4 without blocking the user (stale-snapshot tolerance).

3-B-2: Conflict check for CREATE intents

If the user's intent is to create an object (new table, index, view, etc.) and the target name appears in the data list returned above:

Do NOT generate a CREATE changeset.
Inform the user clearly:

"The <object_type> <name> already exists in the current snapshot for instance <instance_name>. A CREATE changeset would fail. Did you mean to modify it instead? I can generate an ALTER TABLE (add column / modify column / add index / add constraint) changeset if you describe the change you need."
Stop and wait for the user's response. Resume from Step 4 once the user clarifies.

If the name is not in the list (expected case for a genuine new object), proceed to Step 4.

3-B-3: Fetch full metadata for modify/drop intents

When modifying or dropping an existing object, fetch its full metadata (columns, indexes, etc.) — requires non-empty object_names:

harness_get(
  resource_type="database_snapshot_object",
  resource_id="<instance_id>",
  params={
    dbschema_id: "<schema_id>",
    object_type: "Table",
    object_names: ["<table_name>"]
  }
)

If the target name is not in the snapshot list for a modify/drop intent, proceed anyway — the snapshot may be stale; do not block the user.

3-B-4: Resolve foreign key column mappings

Run when the intent involves adding or modifying a foreign key (addForeignKeyConstraint), including FK constraints added during createTable.

Fetch snapshot metadata in one harness_get call. Which tables to include depends on intent:

addForeignKeyConstraint on an existing table: fetch both baseTableName and referencedTableName — needed for snapshot name alignment and column scoring on both sides.
createTable with inline FK constraints: fetch only referencedTableName — the new base table is not in the snapshot yet; base columns come from the changeset definition.

harness_get(
  resource_type="database_snapshot_object",
  resource_id="<instance_id>",
  params={
    dbschema_id: "<schema_id>",
    object_type: "Table",
    object_names: ["<base_table>", "<referenced_table>"]
  }
)

For createTable with inline FK, use object_names: ["<referenced_table>"] only.

Apply column-resolution rules in reference.md → Foreign Key Column Resolution → Column resolution. If snapshot metadata is unavailable, proceed using user-provided names only.

Canonical DBOPS resource_type values (see dbops toolset): database_schema, database_instance, database_default_authoring_instance, database_snapshot_object, database_execute_llm_authoring_pipeline.

Step 4: Generate the Changeset

Produce a valid Liquibase YAML changeset. All YAML generation rules (structure, required fields, rollback, preconditions, timestamps, batch migrations, MongoDB formats, clarifying questions) are in **reference.md** in this directory — follow them exactly.

Changeset author: Derive the author name from .harness_context/user_context.json (if present) or the ## User Context: block in the conversation. Apply these rules in order:

Check for username: Look for user.display_name, uid, or username in the user context.
Normalize the username: Apply these transformations in order:

Convert to lowercase
Remove extra spaces
Convert internal spaces into - (hyphen)
Remove all special c

# DBOPS Changeset Generation

Generate Liquibase database changesets from natural language descriptions,
anchored to a real schema and instance from the Harness DBOPS service.

## When to Use

When the user asks to:

- Create, add, modify, or drop tables, columns, indexes, constraints, or views as Liquibase changeset operations
- Generate a database migration or changeset
- Fix a failed migration or update an existing changeset
- Apply schema changes as Liquibase YAML

## Prerequisites

The Skill tool loads this file (SKILL.md) automatically — do not Read it again.

Before generating Liquibase YAML, Read `reference.md` using the exact path listed in
the Skill tool result. It contains all Liquibase YAML rules, change types, rollback
patterns, batch migration guidelines, MongoDB JSON string requirements, and the
clarifying questions policy. Apply those rules in Step 4 when generating the changeset.

## Full Workflow

### Step 0: Check for Pre-Seeded Context (ALWAYS do this first)

At conversation start, the initial message may contain a JSON block with
pre-selected identifiers injected by the Harness frontend UI:

```json
{
  "dbops_schema_id": "users-schema",
  "dbops_instance_id": "prod-instance"
}
```

**Read this JSON block** (if present) before doing any tool calls.


| What's in context                       | What to do                                            |
| --------------------------------------- | ----------------------------------------------------- |
| `dbops_schema_id` + `dbops_instance_id` | Skip Steps 1 AND 2 — but **immediately fetch instance metadata** via `harness_get(resource_type="database_instance", resource_id="<dbops_instance_id>", dbschema_id="<dbops_schema_id>")` to obtain `connector` (needed in Step 3) and check `hasSnapshot` (needed in Step 3-B). |
| Only `dbops_schema_id`                  | Skip Step 1 — use this schema ID. Then go to Step 2-A |
| Neither                                 | Full Steps 1 and 2                                    |


### Step 1: Discover Database Schemas (skip if `dbops_schema_id` is in context)

Call `harness_list` for the available schemas:

```
harness_list(resource_type="database_schema")
```

The response is a plain JSON array of objects. Each object has:

- `identifier` — used as the schema ID in subsequent calls
- `name` — human-readable name
- `migrationType` — `"Liquibase"` or `"Flyway"` (only Liquibase supported)
- `instanceCount` — number of linked instances
- `primaryDbInstanceId` — the designated instance for LLM authoring (may be empty). If non-empty, Step 2-A uses this directly as the `instance_id` without further discovery.

**Disambiguation:**

- If the array has **one schema**, select it automatically.
- If the array has **multiple schemas**, use `AskUserQuestion` (selection mode):
Show: `[<name> (<identifier>) — <migrationType>, <instanceCount> instances]` for each.
- If the array is **empty**: "No database schemas found in this project. Create one in Harness DBOPS first."
- If `migrationType` is `"Flyway"`: "This skill supports Liquibase schemas only."

### Step 2-A: Resolve Instance from Schema (when only `dbops_schema_id` is known)

When you have a `schema_id` but no `instance_id` (from context OR after Step 1 selection):

1. Call `harness_get` to fetch the full schema:
  ```
   harness_get(resource_type="database_schema", dbschema_id="<schema_id>")
  ```
2. Check the `primaryDbInstanceId` field in the response:
  - **If set**: use it as the `instance_id`. Inform the user:
   "Using primary instance `<primaryDbInstanceId>` for schema `<name>`."
   Then fetch the instance to obtain the `connector` field needed in Step 3:
   ```
   harness_get(resource_type="database_instance", resource_id="<primaryDbInstanceId>",
               dbschema_id="<schema_id>")
   ```
   Read `connector` from the response.
  - **If empty or missing**: fall through to Step 2-B.

### Step 2-B: Auto-select Best Instance (when `primaryDbInstanceId` is empty)

Use the `database_default_authoring_instance` resource to let the server pick the best
instance (oldest with a metadata snapshot; falls back to oldest overall):

```
harness_get(resource_type="database_default_authoring_instance", dbschema_id="<schema_identifier>")
```

The response is `{ identifier: string, name: string, hasSnapshot: boolean, connector: string }`.

**Handling the response:**

- **If the tool call returns results:** Use `identifier` as the `instance_id` and `connector` as the
connector identifier for Step 3 (no separate instance detail fetch needed). Inform the user:
"Using instance `<name>` (`<identifier>`) for schema `<schema_name>`."
If `hasSnapshot` is `true`, the instance has metadata available for snapshot lookups — proceed
to Step 3-B for **any** changeset intent (create, modify, or drop). If `false`, skip Step 3-B entirely.
- **Not found (404 OR empty result):** Reply: *"No instances found for schema `<schema_name>`. Please add an instance in Harness DBOPS first — open **Harness → DBOPS → Schemas → `<schema_name>` → Add Instance**."* — STOP. Do NOT prompt the user for a connector identifier. Do NOT proceed to Step 3. Do NOT generate a changeset.

### Step 3: Resolve Database Engine Type from Connector

**Invariant.** By this point you MUST have a non-empty `connector` value from Step 0 (fast-path
instance fetch), Step 2-A, or Step 2-B — whichever applied. If you do not — for any reason —
STOP and surface the Step 2 "instance not found" message to the user. Never ask the user to
provide a connector identifier directly; connectors are always derived from an existing DBOPS
instance.

Use the `connector` field obtained in Step 0, Step 2-A, or Step 2-B (whichever ran). Fetch the
connector to determine the engine type:

```
harness_get(resource_type="connector", resource_id="<connector>",
            org_id="<org_id>", project_id="<project_id>")
```

The connector is always a JDBC connector. Read `connector.spec.url` and map the prefix:


| `connector.spec.url` prefix          | Engine     |
| ------------------------------------ | ---------- |
| `jdbc:mysql://` or `jdbc:mariadb://` | MySQL      |
| `jdbc:postgresql://`                 | PostgreSQL |
| `jdbc:oracle:thin:`                  | Oracle     |
| `jdbc:sqlserver://`                  | MSSQL      |
| `jdbc:mongodb://`                    | MongoDB    |
| `jdbc:cloudspanner:`                 | Spanner    |
| `jdbc:db2://`                        | DB2        |
| `jdbc:sybase:`                       | Sybase     |
| `jdbc:sqlite:`                       | SQLite     |


**If the URL prefix is unrecognised**, proceed with generic ANSI SQL. Do NOT ask the user.

### Step 3-B (Optional): Snapshot metadata check

Run this step for **any** changeset intent (create, modify, or drop) when `hasSnapshot` is `true`.

**Purpose:**
- For **CREATE** intents: verify the target object does not already exist (conflict check).
- For **modify/drop** intents: align names with the latest snapshot.
- For **foreign key** intents: resolve column mappings from snapshot metadata (Step 3-B-4).

#### 3-B-1: List existing object names

Call with `dbschema_id`, `dbinstance_id`, and the relevant `object_type` (`"Table"`, `"Index"`, `"View"`, etc.):

```
harness_list(
  resource_type="database_snapshot_object",
  filters={
    dbschema_id: "<schema_id>",
    dbinstance_id: "<instance_id>",
    object_type: "Table"
  }
)
```

Returns `{ data: string[] }` — names of objects of that type in the current snapshot.

**If the list API errors or returns an empty `data` array**, treat the snapshot as stale — proceed to Step 4 without blocking the user (stale-snapshot tolerance).

#### 3-B-2: Conflict check for CREATE intents

If the user's intent is to **create** an object (new table, index, view, etc.) and the target name
appears in the `data` list returned above:

- **Do NOT generate a CREATE changeset.**
- Inform the user clearly:
  > "The `<object_type>` `<name>` already exists in the current snapshot for instance `<instance_name>`.
  > A CREATE changeset would fail. Did you mean to modify it instead?
  > I can generate an **ALTER TABLE** (add column / modify column / add index / add constraint)
  > changeset if you describe the change you need."
- **Stop and wait for the user's response.** Resume from Step 4 once the user clarifies.

If the name is **not** in the list (expected case for a genuine new object), proceed to Step 4.

#### 3-B-3: Fetch full metadata for modify/drop intents

When modifying or dropping an **existing** object, fetch its full metadata (columns, indexes, etc.) — requires **non-empty** `object_names`:

```
harness_get(
  resource_type="database_snapshot_object",
  resource_id="<instance_id>",
  params={
    dbschema_id: "<schema_id>",
    object_type: "Table",
    object_names: ["<table_name>"]
  }
)
```

If the target name is **not** in the snapshot list for a modify/drop intent, proceed anyway — the snapshot may be stale; do not block the user.

#### 3-B-4: Resolve foreign key column mappings

Run when the intent involves adding or modifying a foreign key (`addForeignKeyConstraint`),
including FK constraints added during `createTable`.

Fetch snapshot metadata in one `harness_get` call. Which tables to include depends on intent:

- **`addForeignKeyConstraint` on an existing table:** fetch **both** `baseTableName` and
  `referencedTableName` — needed for snapshot name alignment and column scoring on both sides.
- **`createTable` with inline FK constraints:** fetch **only** `referencedTableName` — the
  new base table is not in the snapshot yet; base columns come from the changeset definition.

```
harness_get(
  resource_type="database_snapshot_object",
  resource_id="<instance_id>",
  params={
    dbschema_id: "<schema_id>",
    object_type: "Table",
    object_names: ["<base_table>", "<referenced_table>"]
  }
)
```

For `createTable` with inline FK, use `object_names: ["<referenced_table>"]` only.

Apply column-resolution rules in `reference.md` → **Foreign Key Column Resolution** →
**Column resolution**. If snapshot metadata is unavailable, proceed using user-provided
names only.

**Canonical DBOPS `resource_type` values** (see `dbops` toolset): `database_schema`, `database_instance`, `database_default_authoring_instance`, `database_snapshot_object`, `database_execute_llm_authoring_pipeline`.

### Step 4: Generate the Changeset

Produce a valid Liquibase YAML changeset. All YAML generation rules (structure,
required fields, rollback, preconditions, timestamps, batch migrations, MongoDB
formats, clarifying questions) are in `**reference.md`** in this directory — follow
them exactly.

**Changeset author:** Derive the author name from `.harness_context/user_context.json` (if present) or the `## User Context:` block in the conversation. Apply these rules in order:

1. **Check for username:** Look for `user.display_name`, `uid`, or `username` in the user context.
2. **Normalize the username:** Apply these transformations in order:
  - Convert to lowercase
  - Remove extra spaces
  - Convert internal spaces into `-` (hyphen)
  - Remove all special c
